Spam Advice

The main aim of our spam advice section is to keep you up to date with the latest news on new email spam campaigns, email-based threats and anti-spam solutions that can be deployed to block those threats.

Email spam is more than a nuisance. Even if the number of spam emails received by employees is relatively low, it can be a major drain on productivity, especially for organizations with hundreds or thousands of employees. This section includes articles offering advice on how to reclaim those lost hours by reducing the number of messages that are delivered to your employees’ inboxes.

However, far worse than the lost hours are the malware and ransomware threats that arrive via spam email. Email is now the number one attack vector used by cybercriminals to deliver malware and ransomware. Cybercriminals are now using increasingly sophisticated methods to bypass security solutions. Today’s spam emails use advanced social engineering techniques to fool end users into revealing login credentials and other sensitive information, and installing malicious software on their computers.

Considerable advances have also been made to malware and ransomware. Self-replicating worms are being used to infiltrate entire networks before ransomware attacks occur, maximizing the damage caused and the ransom payments that can be generated. The cost to industry is considerable. Last year ransomware attacks resulted in $1 billion in losses by businesses, with 2017 expected to see those losses rise to a staggering $4 billion. Blocking spam email messages from being delivered is therefore an essential element of any cybersecurity strategy.

Good spam advice can help organizations take action promptly to reduce the risk of email-based attacks. You will find a range of articles in this section on the latest spam email campaigns, data breaches that started with a phishing email and advice on mitigating the risk of phishing and business email compromise scams.

2017 Saw 24% Increase in Tech Support Scams

Microsoft has released new figures that show there has been a sizeable increase in tech support scams over the past year. The number of victims that have reported these scams to Microsoft increased by 24% in 2017. The true increase could be much higher. Many victims fail to report the incidents.

According to Microsoft, in 2017 there were 153,000 reports submitted from customers in 183 countries who had been fooled by such a scam. While not all of the complainants admitted to losing money as a result, 15% said they paid for technical support. The average cost of support was between $200 and $400, although many individuals were scammed out of much more significant amounts. While victims may not willingly pay much more to fix the fictitious problem on their computers, if bank account details are provided to the scammers, accounts can easily be drained. One victim from the Netherlands claims a scammer emptied a bank account and stole €89,000.

The rise in complaints about tech support scams could, in part, be explained by more scammers pretending to be software engineers from Microsoft, prompting them to report the incidents to Microsoft when they realize they have been scammed.

However, the rise in tech support scams is backed up by figures released by the FBI. Its Internet Crime Complaint Center (IC3) received 86% more complaints in 2017 from victims of tech support scams. Around 11,000 complaints were received by IC3 about tech support scams last year and more than $15 million was lost to the scams.

It is easy to see why these scams are so attractive for would-be cybercriminals. In many cases, little effort is required to pull off the scam. All that is required in many cases is a telephone. Cold calling is still common, although many of the scams are now much more sophisticated and have a much higher success rate.

Email is also used. Some tech support scams involve warnings and use social engineering techniques to convince the recipient to call the helpline. Others involve malware, sent as an attachment or downloaded as a result of visiting a malicious website via a hyperlink supplied in the email.

Once installed, the malware displays fake warning messages that convince the user that they have been infected with malware that requires a call to the technical support department.

The use of popups on websites is common. These popups cannot be closed and remain on screen. Browser lockers are also common which serve the same purpose. To prompt the user to call the support helpline.

While many more experienced users would know how to close the browser – CTRL+ALT+DEL and shut down the browser via Windows Task Manager – less experienced users may panic and call the helpline number, especially when the popup claims to be from a well-known company such as Microsoft or even law enforcement.

The typical process used in these tech support scams is to establish contact by telephone, get the user to download software to remove a fictitious virus or malware that has previously been installed by the attackers. Remote administration tools are used that allows the scammer to access the computer. The user is convinced there is malware installed and told they must pay for support. Payment is made and the fictitious problem is fixed.

These techniques are nothing new, it is just that more cybercriminals have got in on the act and operations have been expanded due to the high success rate. Fortunately, there are simple steps to take that can prevent users from falling for these tech support scams.

To avoid becoming a victim of such a scam:

  • Never open any email attachments you receive from unknown senders
  • Do not visit hyperlinks in email messages from unknown senders
  • If contacted by phone, take a number and say you will call back. Then contact the service provider using verified contact information, not the details supplied over the telephone
  • If you are presented with a warning via a popup message or website claiming your device has been infected, stop and think before acting. Genuine warnings do not include telephone numbers and do not have spelling mistakes or questionable grammar
  • If you receive a warning about viruses online and want to perform a scan, download free antivirus software from a reputable firm from the official website (Malwarebytes, AVG, Avast for instance)
  • Before making any call, verify the phone number. Use a search engine to search for the number and see if it has been associated with scams in the past
  • ISPs and service providers rarely make unsolicited telephone calls to customers about viruses and technical issues and offer to fix the device

If you believe you are a victim of a tech support scam, report the incident to the service provider who was spoofed and notify appropriate authorities in your country of residence.

In the USA, that is the Federal Trade Commission or the FBI’s IC3; in the UK it is the National Fraud and Cyber Crime Reporting Center, the European Consumer Center in Ireland, or the equivalent organizations in other countries.

Study Highlights Lack of Effective Security Awareness Training for Employees

Providing security awareness training for employees helps to eradicate risky behaviors that could potentially lead to a network compromise. Training programs should cover all the major threats faced by your organization, including web-based attacks, phishing emails, malware, and social engineering scams via the telephone, text message, or social media channels.

All too often, businesses concentrate on securing the network perimeter with firewalls, deploying advanced anti-malware solutions, and implementing other technological controls such as spam filters and endpoint protection systems, yet they fail to provide effective security awareness training for employees. Even when security awareness training programs are developed, they are often once-a-year classroom-based training sessions that are forgotten quickly.

If you view security awareness training for employees as a once-a-year checkbox item that needs to be completed to ensure compliance with industry regulations, chances are your training will not have been effective.

The threat landscape is changing rapidly. Cybercriminals often change their tactics and develop new methods to attack organizations. If your security program does not incorporate these new methods of attack, and you do not provider refresher security awareness training for employees throughout the year, your employees will be more likely to fall for a scam or engage in actions that threaten the security of your data and the integrity of your network.

Many Businesses Fail to Provide Effective Security Awareness Training for Employees

One recent study has highlighted just own ineffective many security awareness training programs are. Positive Technologies ran a phishing and social engineering study on ten organizations to determine how effective their security awareness programs were and how susceptible employees are to some of the most common email-based scams.

These include emails with potentially malicious attachments, emails with hyperlinks to websites where the employee was required to enter their login credentials, and emails with attachments and links to a website. While none of the emails were malicious in nature, they mirrored real-world attack scenarios.

27% of employees responded to the emails with a link that required them to enter their login credentials, 15% responded to emails with links and attachments, and 7% responded to emails with attachments.

Even a business with 100 employees could see multiple email accounts compromised by a single phishing campaign or have to deal with multiple ransomware downloads. The cost of mitigating real world attacks is considerable. Take the recent City of Atlanta ransomware attack as an example. Resolving the attack has cost the city $2.7 million, according to Channel 2 Action News.

The study revealed a lack of security awareness across each organization. While employees were the biggest threat to network security, accounting for 31% of all individuals who responded to the emails, 25% were team supervisors who would have elevated privileges. 19% were accountants, administrative workers, or finance department employees, whose computers and login credentials would be considerably more valuable to attackers. Department managers accounted for 13% of the responders.

Even the IT department was not immune. While there may not have been a lack of security awareness, 9% of responders were in IT and 3% were in information security.

The study highlights just how important it is not only to provide security awareness training for employees, but to test the effectiveness of training and ensure training is continuous, not just a once a year session to ensure compliance.

Tips for Developing Effective Employee Security Awareness Training Programs

Employee security awareness training programs can reduce susceptibility to phishing attacks and other email and web-based threats. If you want to improve your security posture, consider the following when developing security awareness training for employees:

  • Create a benchmark against which the effectiveness of your training can be measured. Conduct phishing simulations and determine the overall level of susceptibility and which departments are most at risk
  • Offer a classroom-style training session once a year in which the importance of security awareness is explained and the threats that employees should be aware of are covered
  • Use computer-based training sessions throughout the year and ensure all employees complete the training session. Everyone with access to email or the network should receive general training, with job and department-specific training sessions provided to tackle specific threats
  • Training should be followed by further phishing and social engineering simulations to determine the effectiveness of training. A phishing simulation failure should be turned into a training opportunity. If employees continue to fail, re-evaluate the style of training provided
  • Use different training methods to help with knowledge retention
  • Keep security fresh in the mind with newsletters, posters, quizzes, and games
  • Implement a one-click reporting system that allows employees to report potentially suspicious emails to their security teams, who can quickly take action to remove all instances of the email from company inboxes

How to Develop an Effective Security Awareness Program

No matter how many cybersecurity solutions you have deployed or the maturity of your cybersecurity program, it is now essential for develop and effective security awareness program and to ensure all employees and board members are trained how to recognize email threats.

Threat actors are now using highly sophisticated tactics to install malware, ransomware, and obtain login credentials and email is the attack method of choice. Businesses are being targeted and it will only be a matter of time before a malicious email is delivered to an employee’s inbox. It is therefore essential that employees are trained how to recognize email threats and told how they should respond when a suspicious email arrives in their inbox.

The failure to provide security awareness training to staff amounts to negligence and will leave a gaping hole in your security defenses. To help get you on the right track, we have listed some key elements of an effective security awareness program.

Important Elements of an Effective Security Awareness Program

Get the C-Suite Involved

One of the most important starting points is to ensure the C-Suite is on board. With board involvement you are likely to be able to obtain larger budgets for your security training program and it should be easier to get your plan rolled out and followed by all departments in your organization.

In practice, getting executives to support a security awareness program can be difficult. One of the best tactics to adopt to maximize the chance of success is to clearly explain the importance of developing a security culture and to back this up with the financial benefits that come from having an effective security awareness program. Provide data on the extent that businesses are being attacked, the volume of phishing and malicious emails being sent, and the costs other businesses have had to cover mitigating email-based attacks.

The Ponemon Institute has conducted several major surveys and provides annual reports on the cost of cyberattacks and data breaches and is a good source for facts and figures. Security awareness training companies are also good sources of stats. Present information clearly and show the benefit of the program and what you require to ensure it is a success.

Get Involvement from Other Departments

The IT department should not be solely responsible for developing an effective security awareness training program. Other departments can provide assistance and may be able to offer additional materials. Try to get the marketing department on board, human resources, the compliance department, privacy officers. Individuals outside of the security team may have some valuable input not only in terms of content but also how to conduct the training to get the best results.

Develop a Continuous Security Awareness Program

A one-time classroom-based training session performed once a year may have once been sufficient, but with the rapidly changing threat landscape and the volume of phishing emails now being sent, an annual training session is no longer enough.

Training should be an ongoing process provided throughout the year, with up to date information included on current and emerging threats. Each employee is different, and while classroom-based training sessions work for some, they do not work for everyone. Develop a training program using a variety of training methods including annual classroom-based training sessions, regular computer-based training sessions, and use posters, games, newsletters, and email alerts to keep security issues fresh in the mind.

Use Incentives and Gamification

Recognize individuals who have completed training, alerted the organization to a new phishing threat, or have scored highly in security awareness training and tests. Try to create competition between departments by publishing details of departments that have performed particularly well and have the highest percentage of employees who have completed training, have reported the most phishing threats, scored the highest in tests, or have correctly identified the most phishing emails in a round of phishing simulations.

Security awareness training should ideally be enjoyable. If the training is fun, employees are more likely to want to take part and retain knowledge. Use gamification techniques and choose security awareness training providers that offer interesting and engaging content.

Test Employees Knowledge with Phishing Email Simulations

You can provide training, but unless you test your employees’ security awareness you will have no idea how effective your training program has been and if your employees have been paying attention.

Before you commence your training program it is important to have a baseline against which you can measure success. This can be achieved using security questionnaires and conducting phishing simulation exercises.

Conducting phishing simulation exercises using real world examples of phishing emails after training has been completed will highlight which employees are security titans and which need further training. A failed phishing simulation exercise can be turned into a training opportunity.

Comparing the before and after results will show the benefits of your program and could be used to help get more funding.

Train your staff regularly and test their understanding and in a relatively short space of time you can develop a highly effective human firewall that complements your technological cybersecurity defenses. If a malicious email makes it past your spam filter, you can be confident that your employees will have the skills to recognize the threat and alert your security team.

City of Atlanta Ransomware Attack Causes Major Disruption

A city of Atlanta ransomware attack has been causing havoc for city officials and Atlanta residents alike. Computer systems have been taken out of action for several days, with city workers forced to work on pen and paper. Many government services have ground to a halt as a result of the attack.

The attack, like many that have been conducted on the healthcare industry, involved a variant of ransomware known as SamSam.

The criminal group behind the attack is well known for conducting attacks on major targets. SamSam ransomware campaigns have been conducted on large healthcare providers, major educational institutions, and government organizations.

Large targets are chosen and targeted as they have deep pockets and it is believed the massive disruption caused by the attacks will see the victims pay the ransom. Those ransom payments are considerable. Demands of $50,000 or more are the norm for this group. The City of Atlanta ransomware attack saw a ransom demand issued for 6 Bitcoin – Approximately $51,000. In exchange for that sum, the gang behind the attack has offered the keys to unlock the encryption.

SamSam ransomware attacks in 2018 include the cyberattack on the electronic health record system provider Allscripts. The Allscripts ransomware attack saw its systems crippled, with many of its online services taken out of action for several days preventing some healthcare organizations from accessing health records. The Colorado Department of Transportation was also attacked with SamSam ransomware.

SamSam ransomware was also used in an attack on Adams Memorial Hospital and Hancock Health Hospital in Indiana, although a different variant of the ransomware was used in those attacks.

A copy of the ransom note from the city of Atlanta ransomware attack was shared with the media which shows the same Bitcoin wallet was used as other major attacks, tying this attack to the same group.

SecureWorks, the cybersecurity firm called in to help the City of Atlanta recover from the attack, has been tracking the SamSam ransomware campaigns over the past few months and attributes the attacks to a cybercriminal group known as GOLD LOWELL, which has been using ransomware in attacks since 2015.

While many ransomware attacks occur via spam email with downloaders sent as attachments, the GOLD LOWELL group is known for leveraging vulnerabilities in software to install ransomware. The gang has exploited vulnerabilities in JBoss in past attacks on healthcare organizations and the education sector. Flaws in VPNs and remote desktop protocol are also exploited.

The ransomware is typically deployed after access to a network has been gained. SecureWorks tracked one campaign in late 2017 and early 2018 that netted the gang $350,000 in ransom payments. The earnings for the group have now been estimated to be in the region of $850,000.

Payment of the ransom is never wise, as this encourages further attacks, although many organizations have no choice. For some, it is not a case of not having backups. Backups of all data are made, but the time taken to restore files across multiple servers and end points is considerable. The disruption caused while that process takes place and the losses suffered as a result are often far higher than any ransom payment. A decision is therefore made to pay the ransom and recover from the attack more quickly. However, the GOLD LOWELL gang has been known to ask for additional payments when the ransom has been paid.

The city of Atlanta ransomware attack commenced on Thursday March 22, and with the gang typically giving victims 7 days to make the payment. The city of Atlanta only has until today to make that decision before the keys to unlock the encryption are permanently deleted.

However, yesterday there were signs that certain systems had been restored and the ransomware had been eradicated. City employees were advised that they could turn their computers back on, although not all systems had been restored and disruptions are expected to continue.

As of today, no statement has been released about whether the ransom was paid or if files were recovered from backups.

How to Defend Against Ransomware Attacks

The city of Atlanta ransomware attack most likely involved the exploitation of a software vulnerability; however, most ransomware attacks occur as a result of employees opening malicious email attachments or visiting hyperlinks sent in spam emails.

Last year, 64% of all malicious emails involved ransomware. An advanced spam filter such as SpamTitan is therefore essential to prevent attacks. End users must also be trained how to recognize malicious emails and instructed never to open email attachments or click on links from unknown senders.

Software must be kept up to date with patches applied promptly. Vulnerability scans should be conducted, and any issues addressed promptly. All unused ports should be closed, RDP and SMBv1 disabled if not required, privileged access management solutions deployed, and sound backup strategies implemented.

Phishing Attacks in Healthcare Prompt HHS’ Office for Civil Rights to Issue Warning and Advice

Phishing attacks in healthcare are to be expected. Healthcare providers hold vast quantities of data on patients. Hospitals typically employ hundreds or thousands of members of staff, use many third-party vendors, and historically they have had relatively poor cybersecurity defenses compared to other industry sectors. That makes them an attractive target for phishers.

Phishing is a method of gaining access to sensitive information which typically involves a malicious actor sending an email to an employee in which they attempt to get that individual to reveal their login credentials. This is achieved using social engineering techniques to make the email recipient believe the email is a genuine.  For instance, a security alert could inform the email recipient that an online account has been compromised and a password change is required. They are directed to a spoofed website where they are asked to login. The site is fake but looks genuine.

Credentials are entered and passed to the attacker who uses them to gain access to that individual’s account. Phishing can also involve malware. Emails attempt to convince the recipient to open a malware-infected attachment or download a malicious file from a compromised website.

Compliance with HIPAA Rules Helps to Prevent Phishing Attacks in Healthcare

HIPAA Rules require healthcare providers to implement administrative, technical, and physical safeguards to reduce the risk of cyberattacks and phishing. HIPAA only demands a minimum standard for data security be reached, although complying with HIPAA Rules can help to prevent phishing attacks in healthcare.

HIPAA is not technologically specific on the defenses that should be used to protect patient data. Healthcare providers can choose appropriate defenses based on the results of a risk analysis.

It is possible for healthcare organizations to be compliant with HIPAA Rules but still be vulnerable to phishing attacks. If healthcare providers are to block the majority of phishing attacks and truly secure patients’ data, they must go above and beyond the requirements of HIPAA.

HHS’ Office for Civil Rights Warns of Phishing Attacks in Healthcare

Recent phishing attacks in healthcare have prompted the HHS’ Office for Civil Rights to issue a warning about the risk from phishing.

Attacks are now highly sophisticated and can be hard to detect. The emails are often free from spelling mistakes, have near perfect grammar, include brand images and logos, and appear to have been sent from genuine domains. The reasons given for taking a specific course of action are perfectly plausible as is the need for urgent action.

OCR also highlights the rise in spear phishing attacks in healthcare. These attacks involve more targeted attempts to gain access to sensitive information and can be conducted on specific individuals or groups of individuals in an organization – The payroll or HR department for instance.

These attacks often see a CEO or superiors impersonated to add legitimacy to the attack. These attacks tend to require the opening of attachments or visiting links to download malware. Spear phishing emails are also used to request bank transfers or for sensitive information to be sent via email – W2-Forms of employees for instance. Many healthcare employees have been fooled by these scams.

Recent Phishing Attacks in Healthcare

Listed below are some of the recent examples of phishing attacks in healthcare. This is just a small selection of incidents that have resulted in healthcare records being exposed or stolen. The reality is that many data breaches start with a phishing email. Security awareness training company Cofense suggests that as many as 91% of data breaches have their root in a phishing campaign.

November 2017: 1,670 patients of Forrest General Hospital have their PHI exposed following a phishing attack on business associate HORNE.

October 2017: Henry Ford Health System discovers several email accounts were compromised as a result of employees responding to phishing emails. The PHI of 18,470 patients may have been stolen.

September 2017: Employees of UPMC Susquehanna responded to phishing emails with the attackers able to gain access to the PHI of 1,200 patients.

September 2017: A phishing attack on Wisconsin-based Network Health resulted in the PHI of approximately 51,000 patients being exposed.

August 2017: Chase Brexton Health Care in Maryland experienced a phishing attack that saw several email accounts compromised along with the PHI of 16,000 patients.

July 2017: The Medical College of Wisconsin experienced a phishing attack that allowed attackers to gain access to email accounts and the PHI of 9,500 patients.

July 2017: RiverMend Health employees responded to phishing emails and their accounts were accessed by the attackers. The PHI of 1,200 patients was potentially viewed or stolen.

June 2017: A phishing attack on Elderplan Inc., saw several email accounts compromised along with the PHI of 22,000 individuals.

June 2017: MJHS Home Care experienced a phishing attack that saw email access gained by an unauthorized individual. The compromised email accounts contained the PHI of 6,000 patients.

Staff Training and Anti-Phishing Technology

HIPAA does not specifically mention spam filters, but since phishing is used to target employees via email, spam filtering can be considered essential. By filtering out the majority of spam and malicious messages there is less potential for an employee to click on a malicious link or open a malware infected email attachment.

SpamTitan is a cloud-based anti-spam service that blocks more than 99.9% of spam emails from being delivered to inboxes and has a 0.03% false positive rate. Dual antivirus engines (Bitdefender/ClamAV) ensure malicious email attachments are blocked.

Healthcare employees are the last line of defense, so it is important for them to be able to recognize email threats and anti-phishing training is a requirement of HIPAA. In July 2017, OCR issued advice to healthcare organizations on anti-phishing training in its cybersecurity newsletter.

OCR also recommends using multi-factor authentication to ensure email accounts are not compromised when a password is guessed or stolen. Software and operating systems must be kept up to date and fully patched to prevent vulnerabilities from being exploited, and anti-virus and anti-malware solutions should be deployed to prevent infection. Regular backups can also prevent data loss in the event of a malware or ransomware infection.

Sophisticated Multi-Stage Phishing Scam Used to Obtain Millions of Dollars from Businesses

Cybercriminal gangs operating in Nigeria have been discovered to be using phishing kits in a highly sophisticated phishing campaign that has seen millions of dollars obtained from big businesses.

The scammers are regularly fooling employees into revealing their email login credentials – The first stage of the complex scam. The ultimate goal of the attackers is to gain access to corporate bank accounts and convince accounts department employees to make sizeable transfers to their accounts.

According to research conducted by IBM, these scams have been highly successful. Fortune 500 companies are being targeted and losses have been estimated to be of the order of several million dollars.

These scams take time to pull off and considerable effort is required on the part of the scammers. However, the potential rewards are worth the effort. Bank transfers of tens or hundreds of thousands of dollars can be made and business email accounts can be plundered.

A Sophisticated Multi-Stage Phishing Scam

In order to pull off the scam, the attackers must first gain access to at least one corporate email account. Access is gained using phishing emails, with social engineering tactics used to convince employees to click on a malicious link. Those links direct the email recipients to malicious DocuSign login pages where credentials are harvested. These malicious pages have been created on multiple websites.

According to IBM, the gang behind this campaign has created more than 100 of these pages, many of which have been loaded onto genuine websites that have been compromised by the attackers.

Once access to one email account is gained, it is easy to obtain email addresses from the contact list to fool other employees. When an email account is accessed, the attackers search the account for messages involving accounts and payments. The attackers then send emails carrying on conversations between staff members, inserting themselves into conversations and continuing active discussions.

“The attackers typically took a week between the point they gained initial access to a user’s email account and the time they started setting up the infrastructure to prepare a credible ruse,” said IBM’s X-Force researchers.  “During this time, they likely conducted extensive research on the target’s organizational structure, specifically focusing on the finance department’s processes and vendors.”

By setting up email rules and filters, it is possible to block genuine conversations between the employees that could uncover the scam. By doing this, all conversations take place between a specific individual and the attacker.

This method of attack allows the attackers to gain access to banking credentials and send highly convincing emails requesting transfers to their accounts. Targeted employees are unlikely to be unaware that they are not emailing a legitimate contact.

This is a manual, labor-intensive scam involving no malware. That has the advantage of allowing the attackers to evade anti-malware technologies.

How to Protect Against These Sophisticated Email Scams

While these scams are complex, they start with a simple phishing email to gain access to a corporate email account. Once access to an email account has been gained, stopping the scam becomes much harder. The easiest time to prevent such an attack is at the initial stage, by preventing the phishing emails from reaching the inboxes of employees and training employees how to identify phishing emails.

That requires an advanced spam filtering solution that can identify the common signatures of spam and scam emails. By setting aggressive filtering policies, the vast majority of spam emails will be captured and quarantined. With the SpamTitan cloud-based anti-spam service, that equates to more than 99.9% of all spam and malicious emails. SpamTitan also has a particularly low false positive rate – less than 0.03% – ensuring genuine emails are still delivered.

No spam solution can be 100% effective, so it is also important to prepare the workforce and train staff how to identify malicious emails. Security awareness and anti-phishing training allows organizations to create a ‘human firewall’ to complement technical solutions.

Spear phishing – highly targeted email attacks – are harder to block, but it is possible to implement solutions to prevent scams such as this from resulting in credentials being obtained. In this campaign, links are sent in emails. By implementing a web filtering solution, those links can be blocked. In tandem with a spam filter, organizations with a security aware workforce will be well protected from phishing attacks.

Further, the use of two-factor authentication is an important security measure to implement. This will prevent attackers from using an unknown device to access an email account.

Malware Campaign Uses Microsoft Word Without Macros

A new malware campaign has been detected that uses Microsoft Word without macros. Opening a Word document sent via email will not generate the usual warnings that macros must be enabled.

Employees may have been warned to be wary of any emails containing attachments, and never to enable macros on documents received via email. However, the use of Microsoft Word without macros means that even opening email attachments can see malware downloaded, if patches have not been applied.

The multi-stage infection process uses the CVE-2017-11822 Word vulnerability to install an information stealer. CVE-2017-11822 was patched by Microsoft last year, although companies that have not patched their systems recently will be vulnerable to this attack.

CVE-2017-11822 is a vulnerability in Office Equation Editor. The bug has been present in Microsoft Office for the past 17 years. Last year, Microsoft rated the code execution vulnerability as important rather than critical, but many security professionals disagreed and claimed the vulnerability was very dangerous as the bug could be exploited to run arbitrary code and the vulnerability was present in all Office versions.

Microsoft Equation Editor is an application that allows the insertion and editing of complex equations in Office documents as OLE items. Last year, security researchers were able to exploit the vulnerability to run a sequence of commands, including the downloading of files from the Internet. This campaign similarly triggers the downloading of a document – a Rich Text File (RTF) via an OLE object embedded in the Word document.

The OLE object opens the RTF file which uses the vulnerability to run a MSHTA command line, which downloads and runs an HTA file containing a VBScript. The VBScript unpacks a PowerShell script, which in turn downloads and runs the information-stealing malware. The purpose of the malware is to steal passwords from web browsers, email accounts and FTP servers.

The email campaign has been developed to target businesses. So far, four email templates have been detected by SpiderLabs researchers, although more will almost certainly be used over the coming days and weeks.

The four emails intercepted by have the subject lines:

  • TNT Statement of Account
  • Request for Quotation (RFQ)
  • Telex Transfer Notification
  • Swift Copy for Balance Payment

While a patch was released last year to address the vulnerability, Microsoft has taken further steps this Patch Tuesday by removing some of the functionality of Microsoft Equation Editor to prevent CVE-2017-11882 from being exploited.

Businesses can mitigate this attack in three main ways:

  • Ensuring Office installations and operating systems are kept patched and 100% up to date
  • Use of anti spam software to prevent malicious emails from being delivered to end users
  • Training end users on cybersecurity best practices and the danger of opening Office documents from unknown individuals. Consider sending a warning about this campaign and the email subject lines being used

Cryptocurrency Mining Malware Spreading at Lightning Speed

The exponential growth in the price of cryptocurrencies has been accompanied by similar growth in email campaigns spreading cryptocurrency mining malware.  There has also been a big rise in new mining malware variants, with three new malware variants detected in the past week. Conservative estimates suggest one malware variant has already been installed on at least 15 million systems, although the true figure could well be closer to 30 million.

The data comes from the cybersecurity firm Palo Alto Networks, which performed an analysis of the URLs used in the campaign using Bitly telemetry. It is difficult to determine how many systems have been affected since Bitly is not the only URL shortening service being used in the campaign. AdFly is also in use, which suggests the number of infected systems could well be twice as high.

The malicious links for this campaign are being sent in spam email. Clicking the links will direct the user to a malicious website containing executable files that install the Monero mining application XMRig using VBS scripts. The popularity of Monero mining is due to the lower processor demands than cryptocurrencies such as Bitcoin. Monero mining can take place on less powerful computers such as those typically at home. In addition to spam email campaigns, the malicious executable files are being loaded to popular file sharing websites

Symantec reports there has been a rise in browser-based cryptocurrency mining. Websites owners are loading cryptocurrency miners onto their websites that is implemented using a scripting language. The ease of access to JavaScript APIs that can be used for this purpose has increased the popularity of this mining technique. Symantec also reports there has been a 34% rise in mobile applications containing cryptocurrency mining code.

Cryptocurrency mining malware does not pose such a big threat to organizations as other forms of malware and ransomware, but there are implications for businesses. The malware does require a considerable amount of processing power, so there will be an impact on performance on infected machines. Infection will see applications slow considerably, and that will have an impact on productivity.

Campaigns are also being conducted that target businesses. The aim is to installing cryptocurrency mining malware on business servers. These attacks are not email-based, instead vulnerabilities are identified and exploited to install the malware, with Apache Struts (CVE-2017-5638) and DotNetNuke (CVE-2017-9822) vulnerabilities commonly exploited.

Preventing Infection with Cryptocurrency Mining Malware

Businesses can prevent cryptocurrency mining malware from being installed on their servers by ensuring all applications are patched and kept up to date. The patch to fix the Apache Struts vulnerability was released in September 2017, yet many businesses have not applied the patch. The DNN vulnerability has also been patched.

The risk of infections on employee and home computers requires antivirus and antimalware software and an advanced spam filter to prevent malicious messages from reaching inboxes. Businesses should also be training their staff how to recognize malicious emails. Training programs and phishing email simulations have been shown to help reduce susceptibility to email-based attacks by up to 95%.

The past few months have also seen a rise in cryptocurrency mining malware infections via unsecured WiFi networks, with cybercriminals performing man-in-the-middle attacks that hack the WiFi sessions of any user connected to one of the rogue WiFi access points. Unsecured public WiFi hotspots should be avoided, or VPNs used.

How to Block Phishing and Ransomware Attacks

In this post we explain two of the most important strategies to adopt to block phishing and ransomware attacks.

Ensure Malicious Messages Do Not Reach Inboxes

Last year, Netwrix released a report based on a survey that showed 100% of government IT workers believed employees were the biggest threat to security. While those figures are the highest of many such surveys, the common theme throughout all of the research is employees are the most likely cause of a data breach.

One of the biggest areas of weakness is email-based attacks. Research conducted by the Friedrich Alexander University in Germany suggests half of users click links in emails from unknown senders. Those links often lead employees to phishing and malware-laced websites. With such high click rates, it is no surprise that so many IT workers believe employees are the weakest link in their security defenses.

Stopping employees from taking risky actions is difficult, so organizations must do all they can to ensure malicious emails are not delivered to inboxes. Only then, can IT workers be sure that employees will not click links or open dangerous email attachments.

How Does SpamTitan Work?

TitanHQ is a leading provider of spam filtering solutions for enterprises. SpamTitan ensures the vast majority of spam and malicious emails are identified and quarantined and are not delivered to inboxes. SpamTitan has been independently tested and shown to block 99.97% of spam emails, ensuring end users are protected. But what can organizations do to protect their employees from the 0.03% of emails that are delivered to inboxes?

There is No Silver Bullet That Will Block Phishing and Ransomware Threats 100% of the Time

No business can no survive without email and unfortunately, no spam filtering solution can block 100% of all spam emails, 100% of the time. At least not without also blocking many genuine messages. Organizations cannot rely on a spam filter to block phishing and ransomware threats. It is just one important layer of security. Several other layers are required.

Anti-virus and anti-malware solutions are essential for detecting malicious software, but these signature-based security controls are proving less and less effective as years go by. For instance, the solutions are not particularly good at detecting fileless malware.

Most businesses further reduce risk by implementing endpoint protection systems that can detect anomalies and unnatural behavior on endpoints, indicative of an intrusion, malware activity, or ransomware scanning for files and making changes.

However, AV software and endpoint detection systems only detect phishing and ransomware attacks when they are occurring. If you want to block phishing and ransomware attacks, the most effective solution is a human firewall.

IT departments can blame employees for being the weakest link when it comes to security, but if employees are not trained and shown how to recognize malicious emails, they will remain the biggest security threat to an organization.

The Human Firewall – The Best Defense Against Phishing, Malware, and Ransomware Emails

A firewall is the first line of defense, and anti spam software will help to keep inboxes free from malicious messages. The rear guard is made up of your employees. To ensure you have a strong defensive backline, you must provide security awareness training. Many employees do not know that they are taking big risks that could compromise the network. It is up to organizations to ensure that those risks are explained.

Most malware and ransomware attacks involve at least some user interaction: The clicking of a link, the opening of a malicious document, or the enabling of a macro. Employees must be told this is how malware is installed and how access to email accounts and networks is gained. By training the workforce to be more security aware, employees can be turned into a formidable last line of defense.

Security Awareness Training Should Be Continuous

While it was once possible to provide annual security training and be reasonably confident that employees would be able to recognize malicious emails, that is no longer the case. Email-based cyberattacks are now far more sophisticated, and cybercriminals are investing considerably more time in developing highly convincing campaigns. Cybercriminals’ tactics are constantly changing. Training programs must reflect that.

To develop a strong human firewall, training should be ongoing. An annual classroom-based training session should be accompanied by regular CBT training sessions, provided in bite-sized chunks. Cybersecurity should be kept fresh in the mind with monthly email bulletins, as well as ad hoc alerts about new threats.

Research conducted by several security awareness training companies shows, training is very effective. PhishMe, Wombat Security Technologies, and Knowbe4 all suggest that with regular training it is possible to reduce susceptibility to email-based attacks by up to 95%.

Test the Effectiveness of Security Awareness Training with Phishing Simulations

You can backup all your data to ensure you can recover files in the event of a disaster, but if your backups are never tested you can never be sure file recovery is possible.

Similarly, providing security awareness training to employees will not guarantee you have created a strong human firewall. Your firewall must be tested. By sending phishing simulations to your workforce you can find out just how effective your training has been. You can identify weak links – employees that have not grasped the concept of phishing and email security and those individuals can be scheduled additional training. Phishing simulation exercises also help to reinforce training. When a test is failed, it can be turned into a learning opportunity, which helps to improve knowledge retention.

Implement technological solutions to block phishing and ransomware attacks and train your employees and test them on all manner of email-based attacks. When the real deal arrives in an inbox they will be prepared and deal with it appropriately. Fail to block emails or provide high quality training, and your company is likely to have to deal with a costly, and potentially disastrous, email-based attack.

Its Tax Season: Time to Prepare for W2 Phishing Attacks

Tax season is open season for cybercriminals and phishers, who increase their efforts to obtain personal information and Social Security numbers in the run up to – and during – tax season. Until April, we can expect many W2 phishing attacks. Make sure you are prepared and do not fall for a scam.

Anatomy of a W2 Phishing Attack

The most common method of stealing the information needed to file fraudulent tax returns is phishing. Phishing emails are sent in the millions to individuals in an effort to obtain their sensitive information. Individuals must be on high alert for malicious emails during tax season, but it is businesses that are most likely to be targeted.

Payroll employees have access to the W2 forms of the entire workforce. If a single worker can be convinced to email the data, the attacker can file thousands of fraudulent tax returns in the names of employees.

The way cybercriminals get payroll staff to part with sensitive data is by impersonating the CEO or CFO in what is referred to as a Business Email Compromise Scam – otherwise known as a BEC attack or CEO fraud.

The most successful attacks require access to the CEO or CFO’s email account to be gained. That means the CEO or CFO must first be targeted with a spear phishing email and lured into parting with his/her login credentials. Once access to the email account is gained, the impostor can craft an email and send it to a select group of individuals in the company: Payroll and accounts department employees.

The company is researched, individuals likely to have access to W2 forms are identified, and emails are sent. A request is made to attach the W2 forms of all employees who worked for the company in the past year, or for a specific group of employees. A series of emails may be sent, rather than asking for the information straight away.

Since the attacker has access to the CEO’s or CFO’s email account, they can delete sent emails and replies before they are seen by the account holder.

An alternative way of conducting BEC attacks is to spoof an email address. The CFO or CEO is identified from social media sites or LinkedIn, the email address is obtained or guessed based on the format used by the company, and the email is made to appear as if it has come from that email account. An alternative is for the attacker to purchase a similar domain to that used by the company, with two transposed letters for instance. Enough to fool an inattentive worker.

Oftentimes, W2 phishing attacks are not detected until days or weeks after the W2 forms have been sent, by which times IRS tax refund checks have been received and cashed.

How to Defend Against W2 Phishing Attacks

There are several methods that can be used to block W2 phishing attacks. A software or cloud-based anti-spam service should be used to block attacks that come from outside the company. Configured correctly, the spam filter should block spoofed emails and emails sent from similar domains to that used by the company. However, a spam filter will not block emails that come from the CFO or CEOs account.

Multi-factor authentication should be set up on all email accounts to help prevent the first phish that gives the attacker access to a C-suite email address. W2 phishing attacks using spoofed email addresses are much easier to identify and block.

It is therefore important to raise awareness of the threat of W2 phishing attacks with accounts and payroll staff, and anyone else with access to W2 forms. Training can greatly reduce susceptibility to W2 phishing attacks. Training should also be provided to the C-suite, not just employees.

The number of staff who have access to W2 forms should be restricted as far as is possible. Policies should also be introduced that require any request for W2 data to be verified. At a minimum, a request for the data should be checked by a supervisor. Ideally, the request should be confirmed face to face with the sender of the email, or with a quick phone call. The scammers rely on this check not taking place.

AdultSwine Malware Targets Children and Displays Pornographic Ads

More than 60 apps have now been removed from Google Play Store that were laced with AdultSwine Malware – A malware variant that displays pornographic adverts on users’ devices. Many of the apps that contained the malware were aimed at children, including Drawing Lessons Lego Star Wars, Mcqueen Car Racing Game, and Spinner Toy for Slither. The apps had been downloaded by between 3.5 and 7 million users before they were identified and removed.

While the malicious apps have been removed, users who have already downloaded the infected apps onto their devices must uninstall the apps to remove the malware. Simply deleting the apps from the Play Store only prevents more users from being infected. Google has said that it will display warnings on Android phones that have the malicious apps installed to alert users to the malware infection. It will be up to users to then uninstall those apps to remove the AdultSwine malware infection.

Malicious Activities of AdultSwine Malware

AdultSwine malware, and the apps that infect users, were identified and analyzed by security researchers at CheckPoint. The researchers note that once downloaded onto a device, the malware sends information about the user to its command and control server and performs three malicious activities: Displaying advertisements, signing up users to premium services, and installing scareware to fool victims into paying for security software that is not necessary. Information is also stolen from the infected device which can potentially be used for a variety of malicious purposes.

The advertisements are displayed when users are playing games or browsing the Internet, with the adverts coming from legitimate ad networks and the AdultSwine library. The AdultSwine malware library includes extreme adverts containing hardcore pornographic images. Those images appear on screen without warning.

The scareware claims the victim’s device has been infected with a virus that requires the download of an anti-malware app from the Google Play Store, although the virus removal tool is a fake app. Users are told that their phone will be rendered unusable if the app is not downloaded, with a countdown timer used to add urgency.

Registering for premium services requires the user to supply further information, which is done through pop-up phishing adverts. The user is told they have won a prize, but that they must answer four questions to claim their prize. The information they supply is used to register for premium services.

Preventing Infection of Mobile Devices

Generally, users can reduce the risk of a malware infection by only downloading apps from official app stores, although this latest malware campaign has shown that even official stores can be compromised and have malicious apps uploaded.

Google does scan all apps for malware, but new forms of malware can be sneaked into Google Play Store on occasion. Google has announced that from the end of January it will be rolling out a new service called Google Play Protect that is capable of scanning previously downloaded apps to ensure they are still safe to use.

Google recommends only downloading apps for children that have been verified by Google as being ‘Designed for Families’. Those apps may contain adverts, but they have been vetted and strict rules apply covering the advertisements that can be displayed.

It is also important to install some form of anti-malware solution – from a reputable and well-known company – that will scan downloaded content and apps for malware.

Digimine Malware Turns Infected Devices into Cryptocurrency Miners

Digimine malware is a new threat that was first identified from a campaign in South Korea; however, the attacks have now gone global.

Ransomware is still a popular tool that allows cybercriminals to earn a quick payout, but raised awareness of the threat means more companies are taking precautions. Ransomware defenses are being improved and frequent backups are made to ensure files can be recovered without paying the ransom. Not only is it now much harder to infect systems with ransomware, rapid detection means large-scale attacks on companies are prevented. It’s harder to get a big payday and the ability to restore files from backups mean fewer organizations are paying up.

The surge in popularity of cryptocurrency, and its meteoric rise in value, have presented cybercriminals with another lucrative opportunity. Rather than spread ransomware, they are developing and distributing cryptocurrency miners. By infecting a computer with a cryptocurrency miner, attackers do not need to rely on a victim paying a ransom.

Rather than locking devices and encrypting files, malware is installed that starts mining (creating) the cryptocurrency Monero, an alternative to Bitcoin. Mining cryptocurrency is the verification of cryptocurrency transactions for digital exchanges, which involves using computers to solve complex numeric problems. For verifying transactions, cryptocurrency miners are rewarded with coins, but cryptocurrency mining requires a great deal of processing power. To make it profitable, it must be performed on an industrial scale.

The processing power of hundreds of thousands of devices would make the operation highly profitable for cybercriminals, a fact that has certainly not been lost on the creators of Digimine malware.

Infection with Digimine malware will see the victim’s device slowed, as its processing power is being taken up mining Monero. However, that is not all. The campaign spreading this malware variant works via Facebook Messenger, and infection can see the victim’s contacts targeted, and could potentially result in the victim’s Facebook account being hijacked.

The Digimine malware campaign is being spread through the Desktop version of Facebook Messenger, via Google Chrome rather than the mobile app. Once a victim is infected, if their Facebook account is set to login automatically, the malware will send links to the victim’s contact list. Clicking those links will result in a download of the malware, the generation of more messages to contacts and more infections, building up an army of hijacked devices for mining Monero.

Infections were first identified in South Korea; however, they have now spread throughout east and south-east Asia, and beyond to Vietnam, Thailand, Philippines, Azerbaijan, Ukraine, and Venezuela, according to Trend Micro.

A similar campaign has also been detected by FortiGuard Labs. That campaign is being conducted by the actors behind the ransomware VenusLocker, who have similarly switched to Monero mining malware. That campaign also started in South Korea and is spreading rapidly. Rather than use Facebook Messenger, the VenusLocker gang is using phishing emails.

Phishing emails for this campaign contain infected email attachments that download the miner. One of the emails claims the victim’s credentials have been accidentally exposed in a data breach, with the attachment containing details of the attack and instructions to follow to mitigate risk.

These attacks appear to mark a new trend and as ransomware defenses continue to improve, it is likely that even more gangs will change tactics and switch to cryptocurrency mining.

The Cost of HIPAA Noncompliance

In this article we explore the cost of HIPAA noncompliance for healthcare organizations, including the financial penalties and data breach costs, and one of the most important technologies to deploy to prevent healthcare data breaches.

The Health Insurance Portability and Accountability Act (HIPAA)

In the United States, healthcare organizations that transmit health information electronically are required to comply with the Health Insurance Portability and Accountability Act (HIPAA). HIPAA was introduced in 1996 with the primary aim of improving healthcare coverage for employees between jobs, although it has since been expanded to include many privacy and security provisions following the introduction of the HIPAA Privacy and Security Rules.

These rules require HIPAA-covered entities – health plans, healthcare providers, healthcare clearinghouses and business associates – to implement a range of safeguards to ensure the confidentiality, integrity, and availability of protected health information (PHI). Those safeguards include protections for stored PHI and PHI in transit.

HIPAA is not technology specific, if that were the case, the legislation would need to be frequently updated to include new protections and the removal of outdated technologies that are discovered not to be as secure as was initially thought. Instead, HIPAA leaves the actual technologies to the discretion of each covered entity.

In order to determine what technologies are required to keep PHI secure, covered entities must first conduct a risk analysis: A comprehensive, organization-wide analysis of all risks to the confidentiality, integrity, and availability of PHI. All risks identified must be managed and reduced to an appropriate and acceptable level.

The risk analysis is one of the most common areas where healthcare organizations fall afoul of HIPAA Rules. Healthcare organizations have been discovered not to have included all systems, hardware and software in the risk analysis, or fail to conduct the analysis on the entire organization. Vulnerabilities are missed and gaps remain in security controls. Those gaps allow hackers to take advantage and gain access to computers, servers, and databases.

When vulnerabilities are exploited, and a data breach occurs, HIPAA-covered entities must report the security breach to the Department of Health and Human Services’ Office for Civil Rights (OCR): The main enforcer of HIPAA Rules. OCR investigates data breaches to determine whether they could realistically have been prevented and if HIPAA Rules have been violated.

What is the Cost of HIPAA Noncompliance?

When healthcare organizations are discovered not to have complied with HIPAA Rules, financial penalties are often issued. Fines of up to $1.5 million per violation category (per year that the violation has been allowed to persist) can be issued by OCR. The cost of HIPAA noncompliance can therefore be severe. Multi-million-dollar fines can, and are, issued.

The cost of HIPAA noncompliance is far more than any financial penalty issued by OCR, or state attorneys general, who are also permitted to issue fines for noncompliance. HIPAA requires covered entities to notify individuals impacted by a data breach. The breach notification costs can be considerable if the breach has impacted hundreds of thousands of patients. Each patient will need to be notified by mail. If Social Security numbers or other highly sensitive information is exposed, identity theft protection services should be offered to all breach victims.

Forensic investigations must be conducted to determine how access to data was gained, and to establish whether all malware and backdoors have been removed. Security must then be enhanced to prevent similar breaches from occurring in the future.

A data breach often sees multiple lawsuits filed by the victims, who seek damages for the exposure of their information. Data breaches have a major negative impact on brand image and increase patient churn rate. Patients often switch providers after their sensitive information is stolen.

On average, a data breach of less than 50,000 records costs $4.5 million to resolve according to the Ponemon Institute and has an average organizational cost of $7.35 million.

The 78.8 million-record breach experienced by Anthem Inc. in 2015 is expected to have cost the insurer upwards of $200 million. That figure does not include lost brand value and reputation damage, and neither a HIPAA fine from OCR.

A summary of the cost of HIPAA noncompliance, including recent fines issued by attorneys general and OCR has been detailed in the infographic below.

 

The Importance of Protecting Email Accounts

There are many ways that unauthorized individuals can gain access to protected health information – via remote desktop applications, by exploiting vulnerabilities that have not been patched, accessing databases that have been left exposed on the Internet, or when devices containing unencrypted PHI are stolen. However, the biggest single threat to healthcare data comes from phishing.

Research from PhishMe indicates more than 90% of data breaches start with a phishing email, and a recent HIMSS Analytics survey confirmed that phishing is the biggest threat, with email ranked as the most likely source of a healthcare data breach.

Protecting email accounts is therefore an essential part of HIPAA compliance. OCR has already fined healthcare organizations for data breaches that have resulted from phishing emails.

Healthcare organizations should implement a solution that blocks malicious emails and scans for malware and ransomware. In addition to technology, employees must also be trained how to identify malicious emails and taught to be more security aware.

Tips to Avoid Holiday Season Email Scams

Black Friday deals and Cyber Monday discounts see consumers head online in droves looking for bargain Christmas presents, but each year many thousands of consumers are fooled by holiday season email scams. This year will be no different. Scammers are already hard at work developing new ruses to fool unwary online shoppers into parting with their credentials or installing malware.

In the rush to purchase at discounted rates, security awareness often goes out the window and cybercriminals are waiting to take advantage. Hidden among the countless emails sent by retailers to advise past customers of the latest special offers and deals are a great many holiday season email scams. To an untrained eye, these scam emails appear to be no different from those sent by legitimate retailers. Then there are the phishing websites that capture credentials and credit card numbers and websites hosting exploit kits that silently download malware.  It is a dangerous time to be online.

Fortunately, if you take care, you can avoid holiday season email scams, phishing websites, and malware this holiday period. To help you stay safe, we have compiled some tips to avoid holiday season email scams, phishing websites and malware this festive period.

Tips to Keep You Safe This Holiday Season

In the run up to Christmas there will be scams aplenty. To stay safe online, consider the following:

Always carefully check the URL of websites before parting with your card details

Spoofed websites often look exactly like the genuine sites that they mimic. They use the same layouts, the same imagery, and the same branding as retail sites. The only thing different is the URL. Before entering your card details or parting with any sensitive information, double check the URL of the site and make sure you are not on a scam website.

Never allow retailers to store your card details for future purchases

It is a service that makes for quick purchases. Sure, it is a pain to have to enter your card details each time you want to make a purchase, but by taking an extra minute to enter your card details each time you will reduce the risk of your account being emptied by scammers. Cyberattacks on retailers are rife, and SQL injection attacks can give attackers access to retailer’s websites – and a treasure trove of stored card numbers.

Holiday season email scams are rife – Be extra vigilant during holiday season

While holiday season email scams used to be easy to detect, phishers and scammers have become a lot better at crafting highly convincing emails. It is now difficult to distinguish between a genuine offer and a scam email. Emails contain images and company branding, are free from spelling and grammatical errors, and the email requests are highly convincing.  Be wary of unsolicited emails, never open email attachments from unknown senders, and check the destination URL of any links before clicking.

If a deal sounds too good to be true, it probably is

What better time than holiday season to discover you have won a PlayStation 4 or the latest iPhone in a prize draw. While it is possible that you may have won a prize, it is very unlikely if you haven’t actually entered a prize draw. Similarly, if you are offered a 50% discount on a purchase via email, there is a high chance it is a scam. Scammers take advantage of the fact that everyone loves a bargain, and never more so than during holiday season.

If you buy online, use your credit card

Avoid the holiday season crowds and buy presents online, but use your credit card for purchases rather than a debit card.  If you have been fooled by a holiday season scam or your debit card details are stolen from a retailer, it is highly unlikely that you be able to recover stolen funds. With a credit card, you have better protections and getting a refund is much more likely.

Avoid HTTP sites

Websites secured by the SSL protocol are safer. If a website starts with HTTPS it means the connection between your browser and the website is encrypted. It makes it much harder for sensitive information to be intercepted. Never give out your credit card details on a website that does not start with HTTPS.

Beware of order and delivery confirmations

If you order online, you will no doubt want to check the status of your order and find out when your purchases will be delivered. If you recent an email with tracking information or a delivery confirmation, treat the email as potentially malicious. Always visit the delivery company’s website by entering in the URL into your browser, rather than clicking links sent via email. Fake delivery confirmations and parcel tracking links are common. The links can direct you to phishing websites and sites that download malware, while email attachments often contain malware and ransomware downloaders.

Holiday season is a busy, but take your time online

One of the main reason that holiday season email scams are successful is because people are in a rush and fail to take the time to read emails carefully and check attachments and links are genuine. Scammers take advantage of busy people. Check the destination URL of any email link before you click. Take time to think before you take any action online or respond to an email request.

Don’t use the same password on multiple websites

You may choose to buy all of your Christmas gifts on Amazon, but if you need to register on multiple sites, never reuse your password. Password reuse is one of the easiest ways that hackers can gain access to your social media networks and bank accounts. If there is a data breach at one retailer and your password is stolen, hackers will attempt to use that password on other websites.

Holiday season is a time for giving, but take care online and when responding to emails to make sure your hard-earned cash is not given to scammers.

How to Spot a Phishing Email

All organizations should take steps to mitigate the risk of phishing, and one of those steps should be training employees how to spot a phishing email. Employees will frequently have their phishing email identification skills put to the test.

Since all it takes is for one employee to fall for a phishing scam to compromise a network, not only is it essential that all employees are trained how to spot a phishing email, their skills should assessed post-training, otherwise organizations will not know how effective the training has been.

How Common are Phishing Attacks?

Phishing is now the number one security threat faced by businesses in all sectors. Research conducted by the security awareness training company PhishMe suggests that more than 90% of cyberattacks start with a phishing or spear phishing email. While all industry sectors have to deal with the threat from phishing, the education and healthcare industries are particularly at risk. They are commonly targeted by scammers and spammers, and all too often those phishing attacks are successful.

The Intermedia 2017 Data Vulnerability Report showed just how common phishing attacks succeed. Workers were quizzed on security awareness training and successful phishing attacks at their organizations. 34% of high level execs admitted falling for a phishing scam, as did 25% of IT professionals – Individuals who should, in theory, be the best in an organization at identifying phishing scams. The same study revealed 30% of office workers do not receive regular security awareness training. 11% said they were given no training whatsoever and have not been taught how to spot a phishing email.

Overconfidence in Phishing Detection Capabilities Results in Data Breaches

Studies on data breaches and cybersecurity defenses often reveal that many organizations are confident in their phishing defenses. However, many of those companies still suffer data breaches and fall for phishing attacks. Overconfidence in phishing detection and prevention leaves many companies at risk. This was recently highlighted by a study conducted by H.R. Rao at the University of Texas at San Antonio. Rao explained that many people believe they are smarter than phishers and scammers, which plays into the scammers’ hands.

Training Should be Put to The Test

You can train employees how to spot a phishing email, but how can you tell how effective your training has been? If you do not conduct phishing simulation exercises, you cannot be sure that your training has been effective. There will always be some employees that require more training than others and employees that do not pay attention during training. You need to find these weak links. The best way to do that is with phishing simulation exercises.

Conduct dummy phishing exercises and see whether your employees are routinely putting their training into action. If an employee fails a phishing test, you can single them out to receive further training. Each failed simulation can be taken as a training opportunity. With practice, phishing email identification skills will improve.

How to Spot a Phishing Email

Most employees receive phishing emails on a daily basis. Some are easy to identify, others less so. Fortunately spam filters catch most of these emails, but not all of them. It is therefore essential to train employees how to spot a phishing email and to conduct regular training sessions. One training session a year is no longer sufficient. Scammers are constantly changing tactics. It is important to ensure employees are kept up to speed on the latest threats.

During your regular training sessions, show your employees how to spot a phishing email and what to do when they receive suspicious messages. In particular, warn them about the following tactics:

Spoofed Display Names

The 2017 Spear Phishing Report from GreatHorn indicates 91% of spear phishing attacks spoof display names. This tactic makes the recipient believe the email has been sent from a trusted colleague, friend, family member or company. This is one of the most important ways to spot a phishing email.

Mitigation: Train employees to hover their mouse arrow over the sender to display the true email address. Train employees to forward emails rather than reply. The true email address will be displayed.

Email Account Compromises

This year, business email compromise (BEC) scams have soared. These scams were extensively used to obtain W-2 Form tax information during tax season. This attack method involves the use of real email accounts – typically those of the CEO or senior executives – to send requests to employees to make bank transfers and send sensitive data.

Mitigation: Implement policies that require any email requests for sensitive information to be verified over the phone, and for all new bank transfer requests and account changes to be verified.

Hyperlinks to Phishing Websites

The Proofpoint Quarterly Threat Report for Q3 showed there was a 600% increase in the use of malicious URLs in phishing emails quarter over quarter, and a 2,200% increase from this time last year. These URLs usually direct users to sites where they are asked to login using their email credentials. Oftentimes they link to sites where malware is silently downloaded.

Mitigation: Train employees to hover their mouse arrow over the URL to display the true URL. Encourage employees to visit websites by entering the URL manually, rather than using embedded links.

Security Alerts and Other Urgent Situations

Scammers want email recipients to take action quickly. The faster the response the better. If employees stop and think about the request, or check the email carefully, there is a high chance the scam will be detected. Phishing emails often include some urgent request or immediate need for action. “Your account will be closed,” “You will lose your credit,” “Your parcel will not be delivered,” “Your computer is at risk,” Etc.

Mitigation: Train employees to stop and think. An email request may seem urgent and contain a threat, but this tactic is commonly used to get people to take quick action without engaging their brains.

Look for Spelling Mistakes and Grammatical Errors

Many phishing scams come from African countries, Eastern Europe and Russia – Places where English is not the main language. While phishing scams are becoming more sophisticated, and more care is taken crafting emails, spelling mistakes and poor grammar are still common and are a key indicator that emails are not genuine.

Mitigation: Train employees to look for spelling mistakes and grammatical errors. Companies check their emails carefully before sending them.

Why a Spam Filter is Now Essential

Training employees how to spot a phishing email should be included in your cybersecurity strategy, but training alone will not prevent all phishing-related data breaches.  There may be a security culture at your organizations, and employees skilled phish detectors, but every employee can have an off day from time to time. It is therefore important to make sure as few phishing emails as possible reach employees’ inboxes, and for that to happen, you need an advanced spam filtering solution.

SpamTitan blocks more than 99.9% of spam email and includes dual anti-virus engines to ensure malicious messages are blocked. The low false positive rate also ensures genuine emails do not trigger the spam filter and are delivered.

If you want to improve your security defenses, train employees how to spot a phishing email and implement SpamTitan to stop phishing emails from reaching inboxes. With technological and human solutions you will be better protected.

Microsoft Patches 17-Year Old MS Office Remote Code Execution Vulnerability

A serious MS Office remote code execution vulnerability has been patched by Microsoft – One that would allow malware to be installed remotely with no user interaction required. The flaw has been present in MS Office for the past 17 years.

The flaw, which was discovered by researchers at Embedi, is being tracked as CVE-2017-11882. The vulnerability is in the Microsoft Equation Editor, a part of MS Office that is used for inserting and editing equations – OLE objects – in documents: Specifically, the vulnerability is in the executable file EQNEDT32.exe.

The memory corruption vulnerability allows remote code execution on a targeted computer, and would allow an attacker to take full control of the system, if used with Windows Kernel privilege exploits. The flaw can be exploited on all Windows operating systems, including unpatched systems with the Windows 10 Creators Update.

Microsoft addressed the vulnerability in its November round of security updates. Any unpatched system is vulnerable to attack, so it is strongly advisable to apply the patch promptly. While the vulnerability could potentially have been exploited at any point in the past 17 years, attacks exploiting this MS Office remote code execution vulnerability are much more likely now that a patch has been released.

The flaw does not require the use of macros, only for the victim to open a specially crafted malicious Office document. Malicious documents designed to exploit the vulnerability would likely arrive via spam email, highlighting the importance of implementing a spam filtering solution such as SpamTitan to block the threat.

End users who are fooled into opening a malicious document can prevent infection by closing the document without enabling macros. In this case, malware would be installed simply by opening the document.

Microsoft has rated the vulnerability as important, rather than critical, although researchers at Embedi say this flaw is “extremely dangerous.” Embedi has developed a proof of concept attack that allowed them to successfully exploit the vulnerability. The researchers said, “By inserting several OLEs that exploited the described vulnerability, it was possible to execute an arbitrary sequence of commands (e.g. to download an arbitrary file from the Internet and execute it),”

EQNEDT32.exe is run outside of the Microsoft Office environment, so it is therefore not subject to Office and many Windows 10 protections. In addition to applying the patch, security researchers at Embedi recommend disabling EQNEDT32.EXE in the registry, as even with the patch applied, the executable still has a number of other vulnerabilities. Disabling the executable will not impact users since this is a feature of Office that is never needed by most users.

Malicious Spam Email Volume Jumps 85%: Malicious URLs Favored Over Attachments

2017 has seen a major rise in malicious spam email volume. As the year has progressed, the volume of malicious messages sent each month has grown. A new report from Proofpoint shows malicious spam email volume rose by 85% in Q3, 2017.

A deeper dive into the content of those messages shows cybercriminals’ tactics have changed. In 2017, there has been a notable rise in the use of malicious URLs sent via email compared to malicious attachments containing malware. URL links to sites hosting malware have jumped by an astonishing 600% in Q3, which represents a 2,200% increase since this time last year. This level of malicious URLs has not been seen since 2014.

The links direct users to malicious websites that have been registered by cybercriminals, and legitimate sites that have been hijacked and loaded hacking toolkits. In many cases, simply clicking on the links is all that is required to infect the user’s computer with malware.

While there is a myriad of malware types now in use, the biggest threat category in Q3 was ransomware, which accounted for 64% of all email-based malware attacks. There are many ransomware variants in use, but the undisputed king in Q3 was Locky, accounting for 55% of total message volume and 86% of all ransomware attacks. There was also a rising trend in destructive ransomware – ransomware that encrypts files but does not include the option of letting victims’ recover their files.

The second biggest malware threat category was banking Trojans, which accounted for 24% of malicious spam email volume. Dridex has long been a major threat, although in Q3 it was a Trojan called The Trick that become the top banking Trojan threat. The Trick Trojan was used in 70% of all banking Trojan attacks.

Unsurprisingly, with such as substantial rise in malicious spam email volume, email fraud has also risen, up 12% quarter over quarter and up 32% from this time last year.

Cybercriminals are constantly changing tactics and frequently switch malware variants and attack methods, but for the time being at least, exploit kits are still not favored. Exploit kit attacks are at just 10% of the level of last year’s high, with spam email now the main method of malware delivery.

With malicious spam email volume having increased once again, and a plethora of new threats and highly damaging malware attacks posing a very real risk, it is essential that businesses double down on their defenses. The best way to defend against email threats is to improve spam defenses. An advanced spam filtering solution is essential for blocking email threats. The more malicious emails that are captured and prevented from being delivered, the lower the chance of end users clicking on malicious links and downloading malware.

SpamTitan blocks more than 99.9% of spam emails and is one of the most advanced and best spam filters for business use. SpamTitan helps keep inboxes free from malware threats. No single solution can block all email threats, so a spam filtering solution should be accompanied with endpoint security solutions, web filters to block malicious links from being visited, antimalware and antivirus solutions, and email authentication technology.

While it is easy to concentrate on technology to protect against email threats, it is important not to forget to train employees to be more security aware. Regular training sessions, cybersecurity newsletters and bulletins about the latest threats, and phishing simulation exercises can help employees improve their threat detection skills and raise cybersecurity awareness.

US-CERT Warns of Phishing Attacks on Energy Companies

On Friday, the U.S. Department of Homeland Security’s (DHS) computer emergency readiness team (US-CERT) issued a new warning about phishing attacks on energy companies and other critical infrastructure sectors.

Advanced persistent threat (APT) actors are conducting widespread attacks on organizations in the energy, aviation, nuclear, water, and critical manufacturing sectors. Those attacks, some of which have been successful, have been occurring with increasing frequency since at least May 2017. The group behind the attack has been called Dragonfly by AV firm Symantec, which reported on the attacks in September.

DHS believes the Dragonfly group is a nation-state sponsored hacking group whose intentions are espionage, open source reconnaissance and cyberattacks designed to disrupt energy systems.

These cyberattacks are not opportunistic like most phishing campaigns. They are targeted attacks on specific firms within the critical infrastructure sectors. While some firms have been attacked directly, in many cases the attacks occur through a ‘staging’ company that has previously been compromised. These staging companies are trusted vendors of the targeted organization. By conducting attacks through those companies, the probability of an attack on the target firm succeeding is increased.

DHS warns that the attackers are using several methods to install malware and obtain login credentials. The phishing attacks on energy companies have included spear phishing emails designed to get end users to reveal their login credentials and malicious attachments that install malware.

In the case of the former, emails direct users to malicious websites where they are required to enter in their credentials to confirm their identity and view content. While some websites have been created by the attackers, watering hole attacks are also occurring on legitimate websites that have been compromised with malicious code. DHS warns that approximately half of the attacks have occurred through sites used by trade publications and informational websites “related to process control, ICS, or critical infrastructure.”

Phishing emails containing malicious attachments are used to directly install malware or the files contain hyperlinks that direct the user to websites where a drive-by malware download occurs. The links are often shortened URLS creating using the bit.ly and tinyurl URL shortening services. The attackers are also using email attachments to leverage Windows functions such as Server Message Block (SMB) protocol to retrieve malicious files. A similar SMB technique is also used to harvest login credentials.

The malicious attachments are often PDF files which claim to be policy documents, invitations, or resumés. Some of the phishing attacks on energy companies have used a PDF file attachment with the name “AGREEMENT & Confidential.” In this case, the PDF file does not include any malicious code, only a hyperlink to a website where the user is prompted to download the malicious payload.

US-CERT has advised companies in the targeted sectors that the attacks are ongoing, and action should be taken to minimize risk. Those actions include implementing standard defenses to prevent web and email-based phishing attacks such as spam filtering solutions and web filters.

Since it is possible that systems may have already been breached, firms should be regularly checking for signs of an intrusion, such as event and application logs, file deletions, file changes, and the creation of new user accounts.

FormBook Malware Used in Targeted Attacks on Manufacturing and Aerospace Sectors

FormBook malware is being used in targeted attacks on the manufacturing and aerospace sectors according to researchers at FireEye, although attacks are not confined to these industries.

So far, the attacks appear to have been concentrated on organizations in the United States and South Korea, although it is highly likely that attacks will spread to other areas due to the low cost of this malware-as-a-service, the ease of using the malware, and its extensive functionality.

FormBook malware is being sold on underground forms and can be rented cheaply for as little as $29 a month. Executables can be generated using an online control panel, a process that requires next to no skill. This malware-as-a-service is therefore likely to be used by many cybercriminals.

FormBook malware is an information stealer that can log keystrokes, extract data from HTTP sessions and steal clipboard content. Via the connection to its C2 server, the malware can receive and run commands and can download files, including other malware variants. Malware variants discovered to have already been downloaded by FormBook include the NanoCore RAT.

FireEye researchers also point out that the malware can steal passwords and cookies, start and stop Windows processes, and force a reboot of an infected device.

FormBook malware is being spread via spam email campaigns using compressed file attachments (.zip, .rar), .iso and .ace files in South Korea, while the attacks in the United States have mostly involved .doc, .xls and .pdf files. Large scale spam campaigns have been conducted to spread the malware in both countries.

The U.S campaigns detected by FireEye used spam emails related to shipments sent via DHL and FedEx – a common choice for cybercriminals. The shipment labels, which the emails say must be printed in order to collect the packages, are in PDF form. Hidden in the document is a tny.im URL that directs victims to a staging server that downloads the malware. The campaigns using Office documents deliver the malware via malicious macros. The campaigns conducted in South Korea typically include the executables in the attachments.

While the manufacturing industry and aerospace/defense contractors are being targeted, attacks have been conducted on a wide range of industries, including education, services/consulting, energy and utility companies, and the financial services. All organizations, regardless of their sector, should be alert to this threat.

Organizations can protect against this new threat by adopting good cybersecurity best practices such as implementing a spam filtering solution to block malicious messages and stop files such as ISOs and ACE files from being delivered to end users. Organizations should also alert their employees to the threat of attack and provide training to help employees recognize this spam email campaign. Macros should also be disabled on all devices if they are not necessary for general work duties, and at the very least, should be set to be run manually.

It’s National Cyber Security Month: Time to Start Developing a Security Culture

Today is the start of the 14th National Cyber Security Month – A time when U.S. citizens are reminded of the importance of practicing good cyber hygiene, and awareness is raised about the threat from malware, phishing, and social engineering attacks.

The cybersecurity initiative was launched in 2004 by the National Cyber Security Alliance (NCSA) and the U.S. Department of Homeland Security (DHS) with the aim of creating resources for all Americans to help them stay safe online.

While protecting consumers has been the main focus of National Cyber Security Month since its creation, during the past 14 years the initiative has been expanded considerably. Now small and medium-sized businesses, corporations, and healthcare and educational institutions are assisted over the 31 days of October, with advice given to help develop policies, procedures, and implement technology to keep networks and data secure.

National Cyber Security Month Themes

2017 National Cyber Security Month focuses on a new theme each week, with resources provided to improve understanding of the main cybersecurity threats and explain the actions that can be taken to mitigate risk.

Week 1: Oct 2-6 – Simple Steps to Online Safety

It’s been 7 years since the STOP. THINK. CONNECT campaign was launched by the NCSA and the Anti-Phishing Workshop. As the name suggests, the campaign encourages users learn good cybersecurity habits – To assume that every email and website may be a scam, and to be cautions online and when opening emails. Week one will see more resources provided to help consumers learn cybersecurity best practices.

Week 2: Oct 9-13 – Cybersecurity in the Workplace

With awareness of cyber threats raised with consumers, the DHS and NCSA turn their attention to businesses. Employees may be the weakest link in the security chain, but that need not be the case. Education programs can be highly effective at improving resilience to cyberattacks. Week 2 will see businesses given help with their cyber education programs to develop a cybersecurity culture and address vulnerabilities. DHS/NCSA will also be promoting the NIST Cybersecurity Framework and explaining how its adoption can greatly improve organizations’ security posture.

Week 3: Oct 16-20 –Predictions for Tomorrow’s Internet

The proliferation of IoT devices has introduced many new risks. The aim of week three is to raise awareness of those risks – both for consumers and businesses – and to provide practical advice on taking advantage of the benefits of smart devices, while ensuring they are deployed in a secure and safe way.

Week 4: Oct 23-27 –Careers in Cybersecurity

There is a crisis looming – A severe lack of cybersecurity professionals and not enough students taking up cybersecurity as a profession. The aim of week 4 is to encourage students to consider taking up cybersecurity as a career, by providing resources for students and guidance for key influencers to help engage the younger generation and encourage them to pursue a career in cybersecurity.

Week 5: Oct 30-31 – Protecting Critical Infrastructure

As we have seen already this year, nation-state sponsored groups have been sabotaging critical infrastructure and cybercriminals have been targeting critical infrastructure to extort money. The last two days of October will see awareness raised of the need for cybersecurity to protect critical infrastructure, which will serve as an introduction to Critical Infrastructure Security and Resilience Month in November.

European Cyber Security Month

While National Cyber Security Month takes place in the United States, across the Atlantic, European Cyber Security Month is running in tandem. In Europe, similar themes will be covered with the aim of raising awareness of cyber threats and explaining the actions EU citizens and businesses can take to stay secure.

This year is the 5th anniversary of European Cyber Security Month – a collaboration between The European Union Agency for Network and Information Security (ENISA), the European Commission DG CONNECT and public and private sector partners.

As in the United States, each week of October has a different theme with new resources and reports released, and events and activities being conducted to educate the public and businesses on cybersecurity.

European Cyber Security Month Themes

This year, the program for European Cyber Security Month is as follows:

Week 1: Oct 2-6 – Cybersecurity in the Workplace

A week dedicated to helping businesses train their employees to be security assets and raise awareness of the risks from phishing, ransomware, and malware. Resources will be provided to help businesses teach their employees about good cyber hygiene.

Week 2: Oct 9-13 – Governance, Privacy & Data Protection

With the GDPR compliance date just around the corner, businesses will receive guidance on compliance with GDPR and the NIS Directive to help businesses get ready for May 2018.

Week 3: Oct 16-20 – Cybersecurity in the Home

As more IoT devices are being used in the home, the risk of cyberattacks has grown. The aim of week 3 is to raise awareness of the threats from IoT devices and to explain how to keep home networks secure. Awareness will also be raised about online fraud and scams targeting consumers.

Week 4: Oct 23-27 – Skills in Cyber Security

The aim in week 4 is to encourage the younger generation to gain the cyber skills they will need to embark upon a career in cybersecurity. Educational resources will be made available to help train the next generation of cybersecurity professionals.

Use October to Improve Your Cybersecurity Defenses and Train Your Workforce to Be Security Titans

This Cyber Security Month, why not take advantage of the additional resources available and use October to improve your cybersecurity awareness and train your employees to be more security conscious.

When the month is over, don’t shelve cybersecurity for another 12 months. The key to remaining secure and creating a security culture in the workplace is to continue training, assessments, and phishing tests throughout the year. October should be taken as a month to develop and implement training programs and to work toward creating a secure work environment and build a cybersecurity culture in your place of work.

Phishing Warning Issued to Digital Civil Liberties Activists

A warning has been issued to digital civil liberties activists by the Electronic Frontier Foundation about the risk of targeted spear phishing attacks. The phishing warning comes after spate of phishing attacks on digital civil liberties groups over the summer, at least one of which resulted in the disclosure of login credentials.

The attacks were directed at two NGOs – Free Press and Fight for Future – both of which are advocates of net neutrality. The campaign appears to have been conducted by the same individual and included at least 70 phishing attempts between July and August. The attacks started on July 12, which is Save Net Neutrality Day of Action – a day of protest against the FCC’s proposed rollback of net neutrality protections.

While phishing emails are often sent with the purpose of installing malware, in this case the aim was to obtain login credentials to LinkedIn, Google, and Dropbox accounts.

Spear phishing emails were sent using a variety of themes from standard phishing emails to sophisticated and highly creative scams. While most of the attempts failed, the scammer was able to obtain the credentials of at least one account. The compromised Google account was used to send further spear phishing emails to other individuals in the organization. It is unclear what other goals the attacker had, and what the purpose of gaining access to the accounts was.

The phishing campaign was analysed by Eva Galperin and Cooper Quintin at the Electronic Frontier Foundation. They said some of the phishing emails were simple phishing attempts, where the attacker attempted to direct end users to a fake Google document. Clicking the link would direct the user to a site where they were required to enter their Google account details to view the document. Similar phishing emails were sent in an attempt to obtain LinkedIn credentials, using fake LinkedIn notifications. Others contained links to news stories that appeared to have been shared by contacts.

As the campaign progressed, the attacker got more inventive and the attacker started researching the targets and using personal information in the emails. One email was sent in which the scammer pretended to be the target’s husband, signing the email with his name.  Another email was sent masquerading as a hateful comment on a video the target had uploaded to YouTube.

A pornography-related phishing scam was one of the most inventive attempts to gain access to login credentials. Emails were sent to targets masquerading as confirmations from well-known pornographic websites such as Pornhub and RedTube. The emails claimed the recipient had subscribed to the portals.

The initial email was then followed up with a further email containing a sexually explicit subject line. The sender name was spoofed to make it appear that the email was sent from Pornhub. The unsubscribe link on the email directed the user to a Google login page where they were asked for their credentials.

It is not clear whether the two NGOs were the only organizations targeted. Since these attacks may be part of a wider campaign, EFF is alerting all digital civil liberties activists to be aware of the threat. Indicators of compromise have been made available here.

Retefe Banking Trojan Upgraded with SMB Exploit

Ransomware developers have leveraged the EternalBlue exploit, now the criminals behind the Retefe banking Trojan have added the NSA exploit to their arsenal.

The EternalBlue exploit was released in April by the hacking group Shadow Brokers and was used in the global WannaCry ransomware attacks. The exploit was also used, along with other attack vectors, to deliver the NotPetya wiper and more recently, has been incorporated into the TrickBot banking Trojan.

The Retefe banking Trojan is distributed via malicious Microsoft Office documents sent via spam email. In order for the Trojan to be installed, the emails and the attachments must be opened and code must be run. The attackers typically use Office documents with embedded objects which run malicious PowerShell code if clicked. Macros have also been used in some campaigns to deliver the malicious payload.

Researchers at Proofpoint have now obtained a sample of the Retefe banking Trojan that includes the EternalBlue SMBv1 exploit. The EternalBlue module downloads a PowerShell script and an executable. The script runs the executable, which installs the Trojan.

The researchers noted the module used in the WannaCry attacks that allowed rapid propagation within networks – Pseb – was lacking in Retefe, although that may be added at a later date. It would appear that the criminals behind the campaign are just starting to experiment with EternalBlue.

Other banking Trojans such as Zeus have been used in widespread attacks, although so far attacks using the Retefe banking Trojan have largely been confined to a limited number of countries – Austria, Sweden, Switzerland, Japan, and the United Kingdom.

Businesses in these countries will be vulnerable to Retefe, although due to the number of malware variants that are now using EternalBlue, all businesses should ensure they mitigate the threat. Other malware variants will almost certainly be upgraded to include EternalBlue.

Mitigating the threat from EternalBlue (CVE-2017-0144) includes applying the MS17-010 patch and also blocking traffic associated with the threat through your IDS system and firewall. Even if systems have been patched, a scan for vulnerable systems should still be conducted to ensure no devices have been missed.

Since the Retefe Trojan is primarily being spread via spam email, a spam filter should be implemented to prevent malicious messages from reaching end users. By implementing SpamTitan, businesses can protect their networks against this and other malware threats delivered via spam email.

Beware of Equifax Phishing Scams – Cybercriminals Are Typosquatting to Catch the Unwary

Consumers should be wary of Equifax phishing scams in the wake of the massive data breach announced earlier this month. The 143 million records potentially stolen in the breach will be monetized, which means many will likely be sold to scammers.

Trend Micro has suggested a batch of data of this scale could easily be sold for $27 million on underground marketplaces and there would be no shortage of individuals happy to pay for the data. The records include the exact types of information that is sought by identity thieves, phishers, and scammers.

However, it is not necessary to have access to the stolen records to pull of scams. Many opportunistic cybercriminals are taking advantage of consumer interest in the breach and are preparing phishing websites to fool the unwary into revealing their sensitive information. Equifax’s response to the breach has also made it easier for phishers to ply their trade.

Equifax has taken the decision not to inform all breach victims by mail. Only the 209,000 individuals whose credit card numbers were exposed will be receiving a breach notification letter in the mail. All the remaining breach victims will have to check the Equifax website to find out if their information was compromised in the breach. With almost half the population affected, and next to no one being directly informed, virtually the entire population of the United States will need to head online to find out if they have been affected by the breach.

Equifax has set up a new domain where information is provided to consumers on the steps they can take to secure their accounts and minimize the risk of financial harm. The official website is equifaxsecurity2017.com. Via this website, U.S consumers can get regular updates and enroll in the free credit monitoring services being offered.

To obtain the free credit monitoring services, consumers will be routed to a website with the domain trustedidpremier.com and will need to enter their name and the last six digits of their social security number to start the process. Cybercriminals have been quick to take advantage and have registered swathes of websites and are using them to phish for sensitive information.

Consumers Should Be Wary of Equifax Phishing Scams

USA Today reports that 194 domains closely resembling the site used by Equifax have already been registered in the past few days. Those domains closely mimic the site used by Equifax, with transposed letters and common typos likely to be made by careless typists. Many of the sites have already been shut down, but more are likely to be registered.

The purpose of these sites is simple. To obtain sensitive information such as names, addresses, Social Security numbers and dates of birth.

The technique is called typosquatting. It is extremely common and very effective. The websites use the same logos and layouts as the genuine sites and they fool many visitors into revealing their sensitive information. Links to the websites are sneaked into malicious adverts displayed via third-party ad networks and are emailed out in large scale phishing campaigns. Consumers should therefore exercise extreme caution and be alert to Equifax phishing scams sent via email and text message.

Consumers should also be careful about revealing sensitive information online and should treat all email attachments and emailed hyperlinks as potentially malicious. Consumers should look for the warning signs of phishing attacks in any email received, especially if it appears to have been sent from Equifax or another credit monitoring bureau, a credit card company, bank or credit union. Email, text messages and telephone scams are likely to be rife following an attack on this scale.

Additionally, all U.S. citizens should closely monitor their credit and bank accounts, Explanation of Benefits Statements, and check their credit reports carefully. Criminals already have access to a large amount of data and will be using that information for identity theft and fraud over the coming days, weeks, months and years.

Its Time to Increase Office 365 Email Security and Improve Resilience Against Cyberattacks

Cyberattacks on Office 365 users are increasing and Office 365 email security controls are not preventing account compromises at many businesses. If you want to block phishing and malware attacks and prevent costly data breaches, there is no better time than the present to improve Office 365 email security.

Microsoft Office 365 – An Attractive Target for Cybercriminals

Microsoft’s figures suggest there are now more than 70 million active users of Office 365 making it the most widely adopted enterprise cloud service by some distance. 78% of IT decision makers say they have already signed up to Office 365 or plan to do so in 2017 and Microsoft says it is now signing up a further 50,000 small businesses to Office 365 every month. 70% of Fortune 500 companies are already using Office 365 and the number of enterprises transitioning to Office 365 is likely to significantly increase.

Office 365 offers many advantages for businesses but as the number of users grows, the platform becomes and even bigger target for hackers. Hackers are actively seeking flaws in Office 365 and users of the service are increasingly coming under attack. The more users an operating system or service has, the more likely hackers are to concentrate their resources on developing new methods to attack that system.

Cyberattacks on Office 365 are Soaring

Microsoft is well aware of the problem. Its figures show that malware attacks on Office 365 users increased by a staggering 600% last year and a recent survey conducted by Skyhigh Networks showed 71.4% of Office 365 business users have to deal with at least one compromised email account every month. Surveys often overestimate security problems due to having a limited sample size. That is unlikely to be the case here. The survey was conducted on 27 million users of Office 365 and 600 enterprises.

The majority of new malware targets Windows systems simply because there are substantially more users of Windows than Macs. As Apple increases its market share, it becomes more profitable to develop malware to attack MacOS. Consequently, MacOS malware is becoming more common. The same is true for Office 365. More users means successful attacks are much more profitable. If a flaw is found and a new attack method developed, it can be used on millions of users, making searching for flaws and developing exploits well worth the time and effort.

Phishers and hackers are also studying how the security functions of O365 work and are searching for flaws and developing exploits to take advantage. For a few dollars a month, hackers can sign up for accounts to study Office 365. Hackers are also taking advantage of poor password choices to gain access to other users’ accounts to trial their phishing campaigns to ensure they bypass Office 365 email security controls.

Office 365 Email Security Controls are Often Lacking

Given the resources available to Microsoft and its frequent updates, you would expect Office 355 email security to be pretty good. While Office 365 email security is not terrible, for standard users it is not great either. Standard subscriptions include scant security features. To get enhanced security, the enterprise subscription must be purchased or extra email security add-ons must be purchased separately at a not insignificant cost.

Pay for the enterprise subscription and you will get a host of extra security features provided through the Advanced Threat Protection (ATP) security package. This includes message sandboxing, phishing protection, URL tracking and reporting, and link reputation checking. Even when Advanced Threat Protection is used, getting the settings right to maximize protection is not always straightforward.

APT will certainly improve email security, but it is worth bearing in mind that hackers can also sign up for those features and have access to the sandbox. That makes it easier for them to develop campaigns that bypass Office 365 security protections.

Even with both layers of security, the level of protection against malware and phishing is only OK. A 2017 study by SE Labs revealed that even with Microsoft’s Exchange Online Protection and Advanced Threat Protection enabled, email security only achieved a similar score to solutions in the low-middle level of the market. Far lower than the level of protection provided by advanced third party email spam filters such as SpamTitan that work alongside Office 365 to provide even greater protection from malicious email threats.

The Cost of Mitigating an Cybersecurity Incident is Considerable

The cost of mitigating a cyberattack can be considerable, and certainly substantially more than the cost of prevention. The Ponemon Institute/IBM Security 2017 Cost of a Data Breach study shows the average cost of mitigating a cyberattack is $3.62 million.

The recent NotPetya and WannaCry attacks also highlighted the high cost of breach mitigation. The NotPetya attack on Maersk, for example, has been estimated to cost the company up to $300 million, the vast majority of which could have been saved if the patches released by Microsoft in March had been applied promptly.

These large companies can absorb the cost of mitigating cyberattacks to a certain extent, although smaller businesses simply do not have the funds. It is no therefore no surprise that 60% of SMBs end up permanently closing their doors within 6 months of experiencing a cyberattack. Even cash-strapped businesses should be able to afford to improve security to prevent email-based attacks – The most common vector used by cybercriminals to gain access to systems and data.

Increase Office Email 365 Security with a Specialist Email Security Solution

No system can be made totally impervious to hackers and remain usable, but it is possible to improve Office 365 email security and reduce the potential for attacks to an minimal level. To do that, many enterprises are turning to third-party solution providers – specialists in email security – to increase Office 365 email security instead of paying extra for the protection offered by APT.

According to figures from Gartner, an estimated 40% of Microsoft Office 365 deployments will incorporate third-party tools by the end of 2018 with the figure predicted to rise to half of all deployments by 2020.

One of the best ways of improving Office 365 email security is to use an advanced, comprehensive email spam filtering solution developed by a specialist in email security, TitanHQ.

TitanHQ’s SpamTitan offers excellent protection against email-based attacks. The solution has also been developed to perfectly compliment Office 365 to block more attacks and keep inboxes spam and malware free. SpamTitan filters out more than 99.97% of spam and malicious emails, giving businesses the extra level of protection they need. Furthermore, it is also one of the most cost-effective enterprise email security solutions for Office 365 on the market.

SpamTitan Offers Defense In Depth for Office 365 Users

Even with Office 365 Advanced Threat Protection, there are areas where Office 365 does not perform well. According to a study by Osterman Research, Office 365 is capable of blocking all known malware threats. The solution is nowhere near as effective at blocking new malware variants, which are constantly being released. When these new threats are detected and the signatures are added to the database, the threats can be blocked. Until that point, users will be vulnerable. SpamTitan on the other hand is capable of detecting and blocking new malware threats.  SpamTitan is able to anticipate new attacks thanks to pattern learning and intelligence. These predictive capabilities ensures protection against the latest malware variants that signature-based email security solutions fail to detect. By using Bayesian analysis, heuristics and machine learning, new types of spear phishing, whaling, and zero day attacks can be detected and blocked that would otherwise be delivered to inboxes.

SpamTitan includes URL reputation analysis to assess all embedded hyperlinks in an email, including shortened URLs. SURBL filtering and URL detection mechanisms offer superior protection against malicious links contained in emails. Heuristics are used to identify phishing emails from message headers and are constantly updated to detect the latest emerging threats. SpamTitan also includes a greylisting option. Greylisting involves the rejection of all messages along with a request for the message to be resent. Most email servers respond and redeliver messages quickly. Email servers used for spamming are usually busy and these requests are ignored. This is included as an optional feature in SpamTitan, and can be used in combination with whitelists to ensure trusted senders’ messages are always delivered without any delay. Spam confidence levels can be set by user, user group or domain and the solution integrates with Active Directory and LDAP for easy synchronization.

These combinations of features provide superior protection against phishing, spear phishing, ransomware, malware, BEC, impersonation, and zero-day attacks via email, ensuring businesses are protected and messages do not reach end users’ inboxes.

Dropbox Phishing Attacks Used to Download Locky Ransomware

Dropbox phishing attacks are relatively common and frequently fool employees into revealing their sensitive information or downloading malware.

Dropbox is a popular platform for sharing files and employees are used to receiving links advising them that files have been shared with them by their colleagues and contacts and phishers are taking advantage of familiarity with the platform.

There are two main types of Dropbox phishing attacks. One involves sending a link that asks users to verify their email address. Clicking the link directs them to a spoofed Dropbox website that closely resembles the official website. They are then asked to enter in their login credentials as part of the confirmation process.

Dropbox phishing attacks are also used to deliver malware such as banking Trojans and ransomware. A link is sent to users relating to a shared file. Instead of accessing a document, clicking the link will result in malware being downloaded.

Over the past few days, there has been a massive campaign using both of these attack methods involving millions of spam email messages. Last week, more than 23 million messages were sent in a single day.

Most of the emails were distributing Locky ransomware, with a smaller percentage used to spread Shade ransomware. There is no free decryptor available to unlock files encrypted by Locky and Shade ransomware. If files cannot be recovered from backups, victioms will have to dig deep.

Due to the rise in value of Bitcoin of late the cost of recovery is considerable. The malicious actors behind these attacks are demanding 0.5 Bitcoin per infected device – Around $2,400. For a business with multiple devices infected, recovery will cost tens if not hundreds of thousands of dollars.

According to F-Secure, the majority of malware-related spam messages detected recently – 90% – are being used to distribute Locky. Other security researchers have issued similar reports of a surge in Locky infections and spam email campaigns.

To prevent Locky ransomware attacks, businesses should install an advanced spam filtering solution to prevent malicious emails from being delivered to end users’ inboxes. Occasional emails are likely to make it past spam filtering defenses so it is important that all users receive security awareness training to help them identify malicious emails.

A web filter can be highly effective at blocking attempts to visit malicious websites where malware is downloaded, while up to date antivirus and anti-malware solutions can detect and quarantine malicious files before they are opened.

Backups should also be made of all data and systems and those backups should be stored on an air-gapped device. Ransomware variants such as Locky can delete Windows Shadow Volume Copies and if a backup device remains connected, it is probable that backup files will also be encrypted.

Best practices for backing up data involve three backup files being created, on two different media, with one copy stored offsite and offline. Backups should also be tested to make sure files can be recovered in the event of disaster.

The increase in ransomware attacks has prompted the National Institute of Standards and Technology (NIST) to develop new guidance (NIST SPECIAL PUBLICATION 1800-11on recovering from ransomware attacks and other disasters. The draft guidance can be downloaded on this link.

Beware of Hurricane Harvey Phishing Scams

Scenes of the devastation caused by Hurricane Harvey are all over the newsstands and Internet. Videos of the devastation are being broadcast around the globe. The hurricane hit the Texas coast two days ago, forcing tens of thousands of Texas residents to flee their homes. While the hurricane has now been downgraded to a tropical storm, meteorologists are predicting the heavy rainfall will continue at lease for a couple more days and flood waters are continuing to rise.

Following any natural disaster, email scams are rife and extra care must be taken. Hurricane Harvey is no exception. While homeowners were preparing for the worst, cybercriminals were developing Hurricane Harvey phishing scams to fool the unwary into revealing their sensitive information or downloading malware.

Just as looters take advantage of abandoned homes, scammers take advantage of interest in the disaster and send malicious emails that direct users to phishing websites and exploit kits that silently download malware. Scammers capitalize on interest in disasters to conduct malicious activities.

The expected deluge of malicious emails has prompted US-CERT to issue a warning about Hurricane Harvey phishing scams, urging Americans to be extra vigilant. Similar warnings have also been issued by the Better Business Bureau and Federal Trade Commission (FTC).

Hurricane Harvey phishing scams are likely to have eye-catching subject lines offering updates on Hurricane Harvey and stories relating to the disaster or relief efforts. The scam emails contain malicious hyperlinks that will direct users to phishing websites and sites where malware is downloaded. Malicious email attachments are also used to install malware and ransomware.

Users should be extremely wary about opening any emails relating to Hurricane Harvey, especially emails sent from unknown senders. The best advice is not to click on any hyperlink in an email relating to Hurricane Harvey and not to open email attachments sent in those messages.

While email is favored by many scammers, Hurricane Harvey phishing scams can be found on social media sites. Facebook posts and tweets may direct users to phishing websites where credit card details can be obtained or to fake charity websites where donations can be made.

How to Give to Charity to Support the Victims and Avoid Being Scammed

A natural disaster such as this causes devastation for tens of thousands of families. Homes and businesses are lost and families are forced to take refuge in shelters. Displaced families need support and many charities are accepting donations to help the victims.

However, all may not be as it seems. Scammers spoof legitimate charities and set up bogus websites where donations can be made. Oftentimes, legitimate charities are spoofed and donations never make it to the victims.

The advice offered by the Federal Trade Commission is to be wary of any request for donations to support the victims of Hurricane Harvey. Rather than respond directly to email and social media requests for donations, visit the charity webpage directly and independently verify the charity is legitimate.

The Better Business Bureau is maintaining a list of BBB-accredited charities that are accepting donations to support the victims of Hurricane Harvey, as is Guidestar. By checking the legitimacy of the charity, users can make sure their donations reach the victims of the hurricane and do not end up lining criminals’ pockets.

If you are considering donating to a charity that is not on either list, before making a donation, check that the charity is registered by contacting the National Association of State Charity Officials.

Locky Ransomware Spam Campaigns Detected Spreading Two New Variants

Two new Locky ransomware spam campaigns have been detected this month, each being used to spread a new variant of the cryptoransomware. The campaigns have been launched after a relatively quiet period for ransomware attacks, although the latest campaigns show that the threat of ransomware attacks in never far away.

Previously, Locky ransomware spam campaigns have been conducted using the Necurs botnet – one of the largest botnets currently in use. One of the campaigns, spreading the Locky variant Lukitus is being conducted via Necurs. The other campaign, which is spreading the Diablo Locky variant, is being sent via a new botnet consisting of more than 11,000 infected devices. Those devices are located in 133 countries according to Comodo Threat Research Labs. The botnet appears to have been built quickly and is understood to be growing, with most infected devices in Vietnam, India, Mexico, Turkey and Indonesia.

The failure to backup files is likely to prove costly. The ransom demand issued by the attackers ranges between 0.5 and 1 Bitcoin per infected device – approximately $2,150 to $4,300 per machine. There is still no decryptor for Locky ransomware. Victims face file loss if they do not have a viable backup to restore files. Locky ransomware variants remove Shadow Volume Copies to hamper recovery without paying the ransom.

The Diablo Locky variant renames encrypted files with a unique 16-character file name and adds the diablo6 extension, while the Lukitus variant adds the .lukitus extension.

The two new Locky ransomware spam campaigns differ in their method of delivery of the ransomware, although both involve spam email. The Diablo campaign, which started on August 9, uses various attachments including pdf, doc, and docx files, although infection occurs via malicious macros.

Opening the infected documents will present the user with indecipherable data and a prompt to enable macros to view the content of the document. Enabling macro saves a binary to the device, runs it, and downloads the Locky payload.

The email subjects in this campaign are varied, although in many of the emails the attackers claim the attachment is a missed invoice or purchase order.

The Lukitus campaign was first detected on August 16 and has been mostly used in attacks in the United States, UK, and Austria, although there have also been successful attacks in Italy, Sweden, China, Russia, Botswana, Netherlands and Latvia.

This campaign uses zipped (zip and rar) attachments. The zip files contain JavaScript files, which if run, will download the Lukitus Locky variant.

As with all ransomware attacks via spam email, the best defense is an advanced spam filter to block the emails and prevent them from being delivered to end users. Employees should already have been trained on the threat from ransomware. Now would be a good time to issue a reminder via email to all employees of the current threat.

Recovery without paying the ransom depends on viable backup copies existing. Since Locky can encrypt backup files, backup devices should be disconnected after a backup has been made. Organizations should also ensure three copies of backups exist, on two different media, with one copy stored off site – the 3-2-1 approach to backing up.

Retail Industry Data Breaches Double in a Year

The retail industry is under attack with cybercriminals increasing their efforts to gain access to PoS systems. Retail industry data breaches are now being reported twice as frequently as last year, according to a recent report from UK law firm RPC.

Retailers are an attractive target. They process many thousands of credit card transactions each week and store huge volumes of personal information of consumers. If cybercriminals can gain access to Point of Sale systems, they can siphon off credit and debit card information and stolen consumer data can be used for a multitude of nefarious purposes.

Many retailers lack robust cybersecurity defenses and run complex systems on aging platforms, making attacks relatively easy.

While cyberattacks are common, the increase in data breaches does not necessarily mean hacks are on the rise. RPC points out that there are many possible causes of data breaches, including theft of data by insiders. Retailers need to improve they defenses against attacks by third parties, although it is important not to forget that systems need to be protected from internal threats.

Preventing retail industry data breaches requires a range of cybersecurity protections, but technology isn’t always the answer. Errors made by staff can easily result in cybercriminals gaining easy access to systems, such as when employees respond to phishing emails.

Employees are the last line of defense and that defensive line is frequently tested. It is therefore essential to improve security awareness. Security awareness training should be provided to all employees to raise awareness of the threat from phishing, malware and web-based attacks.

Phishing emails are the primary method of spreading malware and ransomware. Training staff how to identify phishing emails – and take the correct actions when email-based threats are received – will go a long way toward preventing retail industry data breaches. Employees should be taught the security basics such as never opening email attachments or clicking hyperlinks in emails from unknown individuals and never divulging login credentials online in response to email requests.

Employees can be trained to recognize email-based threats, although it is important to take steps to prevent threats from reaching inboxes. An advanced spam filtering solution is therefore a good investment. Spam filters can block the vast majority of spam and malicious emails, ensuring employees security awareness is not frequently put to the test. SpamTitan blocks more than 99.9% of spam and malicious emails, ensuring threats never reach inboxes.

Web-based attacks can be blocked with a web filtering solution. By carefully controlling the types of websites employees can access, retailers can greatly reduce the risk of malware downloads.

As the recent WannaCry and NotPetya malware attacks have shown, user interaction is not always required to install malware. Both of those global attacks were conducted remotely without any input from employees. Vulnerabilities in operating systems were exploited to download malware.

In both cases, patches had been released prior to the attacks that would have protected organizations from the threat. Keeping software up to date is therefore essential. Patches must be applied promptly and regular checks conducted to ensure all software is kept 100% up to date.

This is not only important for preventing retail industry data breaches. Next year, the General Data Protection Regulation (GDPR) comes into force and heavy fines await retailers that fail to do enough to improve data security. Ahead of the May 25, 2018 deadline for compliance, retailers need to improve security to prevent breaches and ensure systems are in place to detect breaches rapidly when they do occur.

NSA Exploit Used in Cyberattacks on Hotel WiFi Networks

Security researchers have discovered a wave of cyberattacks on hotel WiFi networks that leverage an NSA exploit – EternalBlue – for a vulnerability that was fixed by Microsoft in March.

The same exploit was used in the WannaCry ransomware attacks in May and the NotPetya wiper attacks in June. Even though the malware campaigns affected hundreds of companies and caused millions (if not billions) of dollars of losses, there are still companies that have yet to apply the update.

The recent cyberattacks on hotel WiFi networks have affected establishments in the Middle East and Europe. Once access is gained to hotel networks, the attackers spy on guests via hotel WiFi networks and steal their login credentials.

Researchers at FireEye discovered the new campaign, which they have attributed to the Russian hacking group APT28, also known as Fancy Bear. Fancy Bear is believed to receive backing from the Russian government and has performed many high profile cyberattacks in recent years, including the cyberattack on the World Anti-Doping agency (WADA). Following that attack, Fancy Bear published athletes’ therapeutic use exemption (TUE) data.

In contrast to the WannaCry and NotPetya attacks that were conducted remotely without any user involvement, the latest campaign is being conducted via a spear phishing campaign. The hacking group sends malicious emails to hotel employees and uses email attachments to download their backdoor – Gamefish. In this case, the attachment appears to be a reservation form for a hotel booking. Gamefish is installed if hotel employees run the macros in the document.

Once the backdoor is installed, the hackers search for internal and guest WiFi networks using EternalBlue and spread to other devices. Once embedded in computers that control the WiFi networks, the attackers can launch attacks on devices that attempt to connect to the hotel WiFi network.

The hackers use the open-source Responder tool to listen for MBT-NS (UDP/137) broadcasts from devices that are attempting to connect to WiFi network resources. Instead of connecting, they connect to Responder which obtains usernames and hashed passwords. That information is transferred to a computer controlled by the attackers. Once the hashed passwords have been cracked they can be used to attack hotel guests.

The names of the affected hotels have not been disclosed, although FireEye has confirmed that at least one Middle Eastern hotel and seven in Europe have been attacked. The hotels were well respected establishments likely to be frequented by high-net worth guests and business travellers.

The advice for travellers is to exercise caution when connecting to hotel WiFi networks, such as avoiding accessing online bank accounts or better still, avoiding connecting to hotel WiFi networks altogether. While the use of a VPN when connecting to hotel WiFi networks is a good idea, in this case the attack can occur before a secure VPN connection is made.

FireEye reports that this type of attack is difficult to detect and block. The attackers passively collect data and leave virtually no traces. Once login credentials have been obtained, guests are vulnerable and not just while they are at the hotel. FireEye believes the credentials are then used to attack individuals when they return home and connect to their home networks.

The best way for hotels to prevent cyberattacks on hotel WiFi networks such as this is by blocking the phishing and spear phishing attacks that lead to installation of the malware. Hotels should ensure all employees are provided with security awareness training and a spam filtering solution such as SpamTitan is deployed to stop malicious emails from being delivered to employees’ inboxes.

Phishing by SMS: Smishing Attacks on The Rise

Smishing attacks are on the rise. Cybercriminals have been turning to the Short Message Service – SMS – to conduct phishing campaigns to gather personal information for identity theft and fraud. Smishing is also used to fool mobile device users into installing malware.

Like phishing emails, smishing attacks use social engineering techniques to get users to complete a specific action, often to click on a link that will direct them to a webpage where they are asked to provide sensitive information or to download a file to their device. Most commonly, the aim of smishing is to obtain personal information such as usernames and passwords to online bank accounts.

Many organizations have implemented spam filtering solutions that capture phishing emails and prevent them from being delivered to end users’ inboxes. Security awareness training is also provided, with the threat of phishing explained to employees.  However, the best practices that are taught are not always applied to SMS messages and spam controls do not block SMS messages.

In contrast to emails, which are often ignored, people also tend to access their SMS messages much more rapidly than emails. Text messages are typically opened within seconds, or minutes, of them being received. Cybercriminals are well aware that their malicious MS messages will be opened and read.

Cybercriminals use the same techniques for smishing attacks that are used on email phishing scams. The messages inject a sense of urgency, requiring an action to be taken quickly. The messages are designed to grab attention, with security threats one of the most common themes. The attackers typically impersonate banks, credit card companies, email providers, social media networks or online retailers and warn of security issues such as potential fraudulent activity, imminent charges that will be applied or they threaten account closure.

Messages may even appear to have been sent by a contact, either using a stolen mobile or by spoofing someone who is known and trusted. Messages may include a link to an interesting article, a photograph or a social media post for example.

Smishing attacks started with SMS messages, although similar scams are now being conducted on other messaging platforms such as WhatsApp, Skype and Facebook Messenger.

Blocking smishing attacks is difficult. The key to avoiding becoming a victim is awareness of the threat and adopting the same security best practices that can protect end users on email.

  • As with email, when receiving an odd message, stop and think about the request. Could it be a scam?
  • Even if the message suggests urgent action is required, take time to consider what is being asked. Smishing attacks work because people respond without thinking.
  • It is important not to respond to a SMS message that has been sent from an unknown sender. If you respond, the person who sent the message will be aware that messages are being received.
  • If a message containing a hyperlink is received, do not click on the link. Delete the message.
  • Never send any sensitive information via text message. Legitimate companies will not ask you to send sensitive information by text message.
  • If you are concerned about the contents of a text message, check with the institution concerned, but do not use links or telephone numbers sent in the message. Independently verify the phone number and call or find the correct website via the search engines.
  • If you are a business that provides employees with access to a WiFi network, it is possible to prevent employees from visiting malicious websites linked in smishing campaigns. WebTitan Cloud for WiFi is a web filter for WiFi networks that prevents users from visiting malicious websites, such as those used in smishing attacks.

Supreme Court Phishing Scam Targets Law Firms in Ireland

Law firms in Eire and Northern Ireland are being targeted with a new Supreme Court phishing campaign that is being used to fool recipients into visiting a malicious website.

The email appears to have been sent from the Supreme Court and refers to a new/updated Statutory Instrument. The emails that have been detected so far include a PDF file containing further details, although the attachment will divert the recipient to a malicious domain.

The Supreme Court phishing emails add a sense of urgency, as is common in phishing campaigns, telling the recipient to read the information in the attached document by this Friday.

The emails that have been reported have the subject line – Supreme Court (S.I. No691/2017) – although it is possible there are other variations along the same theme.  The Courts Service has confirmed that the emails are not genuine and should be deleted without being opened. The phishing scam has been reported to the Gardaí and the Courts Service IT team is also investigating and a warning has been issued.

Supreme Court phishing scams are common. In February this year, the UK Supreme Court also issued a warning after numerous emails were received claiming to be subpoenas for court appearances in relation to a crime that the recipient had committed. In that case, a link was included to provide the court with all of the necessary information about the case. Receipents of the email were told to submit the information within 12 days or the case would proceed in their absence.

As the UK Supreme Court pointed out, it does not issue subpoenas to appear in court for criminal cases, although many law-abiding citizens would be aware of typical procedures associated with criminal cases. The fear generated by a potential court appearance for an unknown crime would likely see many email recipients open the message, click on the link and reveal their personal information.

The purpose of Supreme Court phishing emails is usually to obtain sensitive information under the guise of confirming the recipient’s identity. The information gathered by the phishing emails can be used for identity theft or other forms of fraud. Emails such as this are also used to spread malware or ransomware.

The emails are designed to scare people into responding and they can be highly effective. However, there are usually a variety of telltale signs that the email is not genuine. Before clicking or taking any requested action, it is important to stop, think and not to panic. Check the email for misspellings, grammatical errors and anything out of the ordinary.

If a link is included in the email, hover the mouse arrow over it to find out the true URL to see if it will direct you to a genuine domain. If the email contains an attachment, do not open it. If you are worried about the email, contact the organization that claims to have sent the message by obtaining the correct contact details from the Internet and verify the authenticity of the request.

In the most part, any serious matter such as a subpoena or important change to legislation would be unlikely to be communicated via email, and certainly not in an email attachment or via a link to a domain.

IRS Launches Campaign to Raise Awareness of Phishing Attacks on Tax Professionals

Phishing attacks on tax professionals are soaring. Tax professionals across the United States have been extensively targeted by cybercriminals this tax season who fool them into disclosing sensitive information such as login credentials and tax information.

The IRS has received 177 reports from tax professionals that have fallen for the scams this year and have disclosed sensitive information, although the victim count is likely to be much higher since not all phishing attacks are reported. Currently, the IRS is receiving between three and five new reports of successful phishing scams each week.

Many of the victims have reported large data losses as a result of the phishing scams. Tax information is used by cybercriminals to file fraudulent tax returns in the victims’ names. The data can also be used for identity theft.

The IRS says tax professionals are being extensively targeted by highly organized criminal gangs in the United States, as well as international crime rings.  The IRS points out that the criminals conducting phishing attacks on tax professionals “are well funded, knowledgeable and creative.”

Targets are researched and information is often included in the emails that is relevant to the recipient. The name and address of the target are often used in the emails and the requests are highly credible. Emails may request data or provide a hyperlink for the recipient to click. Clicking the link results in malware being downloaded that gives the attacker access to the computer. Keyloggers are often downloaded that record and transmit passwords.

The Anti Phishing Working Group tracked 1.2 million unique phishing attacks last year, representing a 65% rise from 2015. Those scams often involve millions of emails. Currently, APWG is tracking an average of 92,564 unique phishing attacks each month.

Phishing attacks on tax professionals can be highly sophisticated, but in the majority of cases it is possible to block attacks by employing basic security measures. Unfortunately, many organizations overlook these steps.

The IRS is working closely with the tax industry and state tax agencies as the ‘Security Summit’. The Security Summit has recently launched a new campaign to help tackle the problem of phishing by raising awareness of the threat via a new “Don’t Take the Bait” campaign.

Over the next 10 weeks, the Security Summit will send weekly emails to raise awareness of the different types of phishing scams and other threats. The Security Summit has kicked off the campaign with spear phishing, which will be followed by education efforts to raise awareness of CEO fraud/BEC scams, ransomware attacks, remote account takeovers, EFIN thefts and business identity theft.

Blocking phishing attacks on tax professionals requires layered defenses, one of the most important being the use of software solutions to prevent phishing emails from being delivered to end users’ inboxes. SpamTitan blocks more than 99.9% of email spam and keeps inboxes free from malicious messages. If emails are not delivered, employees will not be tested.

Even with software solutions in place it is important for all employees to be aware of the threat from phishing. Security training should be provided to teach employees how to recognize the tell-tale signs of phishing emails and organizations should try to develop a culture of security awareness.

IRS Commissioner John Koskinen said “Doing nothing or making a minimal effort is no longer an option. Anyone who handles taxpayer information has a legal responsibility to protect it.”

The IRS recommends several measures to reduce risk:

  • Educate all employees on the risk from spear phishing and phishing in general
  • Ensure strong passwords are used
  • Always question emails – Never take them at face value
  • Never click a link without first checking the destination URL – Hover the mouse arrow over a masked link to find the true URL
  • Use two-factor authentication for all email requests to send sensitive data – Confirm with the sender via the telephone
  • Use security software to block phishing emails and malware and ensure the software is updated automatically
  • Use the security settings in tax preparation software
  • Report suspicious emails to the IRS

URL Padding Used in Latest Facebook Phishing Scam

A new Facebook phishing scam has been detected that attempts to fools end users into believing they are on the genuine Facebook site using a technique called URL padding. The attack method is being used in targeted attacks on users of the mobile Facebook website.

As with other Facebook phishing scams, the aim of the attackers is to get end users to reveal their Facebook login credentials. The scam takes advantage of poor security awareness and a lack of attentiveness.

URL padding – as the name suggests – involves padding the URL with hyphens to mask the real website that is being visited. The URLs being used by the attackers start with m.facebook.com, which is the correct domain for the genuine Facebook website. In a small URL bar on mobile phones, this part of the URL will be clearly visible.

What follows that apparent domain is a series of hyphens: m.facebook.com————-. That takes the latter part of the domain outside the viewable area of the address bar. End users may therefore be fooled into thinking they are on the genuine website as they will not see the last part of the URL. If they were to check, they would see that m.facebook.com————- is actually a subdomain of the site they are visiting.

The hyphens would be a giveaway that the site is not genuine, but the attackers add in an additional word into the URL such as ‘validate’ or ‘secure’ or ‘login’ to add authenticity.

The attackers have lifted the login box and branding from Facebook, so the login page that is presented appears to be the same as is used on the genuine site.

One telltale sign that all is not as it appears is the use of hxxp:// instead of https:// at the start of the URL, a sure sign that the site is not genuine. Even so, many Facebook users would be fooled by such a scam. URL padding is also being used to target users of other online services such as Apple iCloud and Comcast.

Facebook accounts contain a wealth of information that can be used in future spear phishing campaigns or attacks on the victims’ contacts.  PhishLabs, which discovered the new scam, says the attackers are currently using this phishing scam for the latter and are using the account access to spam end users’ contacts and conduct further phishing campaigns.

While the scam has been detected, it is currently unclear how links to the phishing website are being distributed. While it is possible that they are arriving via spam email, Phishlabs suggests SMS messages or messenger services are being used.

Phishing Attacks Likely to Follow Hotels.com Breach

The Texas-based online hotel booking website Hotels.com is notifying customers that some of their sensitive information has been exposed. The Hotels.com breach potentially involved usernames and passwords, email addresses, and the last four digits of site users’ credit card numbers.

Users’ accounts were hacked between May 22 and May 29, although at this stage it is unclear exactly how many individuals have been affected. While full credit card numbers were not obtained, the Hotels.com breach will see users face an elevated risk of phishing attacks.

Phishing emails come in many guises, although it is common for users of a site that has experienced a data breach or security incident to receive warning emails about the attack. The emails rightly claim that a user’s sensitive information has been compromised; however, the emails do not come from the company that experienced the breach. Instead, it is the cybercriminals who conducted the attack, or individuals who have bought stolen data from the attackers, that send the emails.

A typical phishing scenario sees individuals informed that their usernames and passwords have been compromised. A link is included in the emails to allow the user to reset their password or activate additional security controls on their account.

That link will direct the user to a phishing website where further information is obtained – the missing digits from their credit card number for example – or other personal information. Alternatively, the link could direct the user to a malicious website containing an exploit kit that downloads malware onto their computer.

Hotels.com customers were targeted in a 2015 phishing campaign which resulted in many site users divulging information such as names, phone numbers, email addresses and travel details. That information could be used in further scams or even for robberies when victims are known to be on vacation.

The Hotels.com breach is the latest in a number of attacks on online companies. While it is currently unclear how access to customers’ accounts was gained, a letter emailed to affected users suggests the attacks could be linked to breaches at other websites. The letter suggests access to online accounts could have resulted from password reuse.

Reusing passwords on multiple online platforms is a bad idea. While it is easier to remember one password, a breach at any online website means the attackers will be able to access accounts on multiple sites.

To prevent this, strong, unique passwords should be used for each online account. While these can be difficult to remember, a password manager can be used to store those passwords. Many password managers also help users generate strong, unique passwords. Users should also take advantage of two-factor authentication controls on sites whenever possible to improve security.

Since many businesses use hotel booking websites such as Hotels.com, they should be particularly vigilant for phishing emails over the coming weeks, especially any related to hotels.com. To protect against phishing attacks, we recommend using SpamTitan. SpamTitan blocks more than 99.9% of phishing and other spam emails, reducing the risk of those messages being delivered to end users. Along with security awareness training and phishing simulation exercises, businesses can successfully defend against phishing attacks.

Phishing Attacks on Healthcare Organizations Can Result in HIPAA Fines

In the United States, the healthcare industry is being targeted by cybercriminals, with phishing attacks on healthcare organizations one of the easiest and most common methods of gaining access to email accounts and protected health information. A phishing email is sent to a healthcare employee along with a seemingly legitimate reason for revealing their login credentials. Doing so will give the attackers access to an email account and the protected health information of patients in those emails. Emails accounts contain a wealth of information that can be used for further attacks. A compromised email account can be used to send further phishing emails within a company. One response to a phishing email can see many email accounts compromised. A single phishing email can result in a major security incident and costly data breach.

There have been many phishing attacks on healthcare organizations this year and the past 12 months has seen numerous phishing-related data breaches added to the Department of Health and Human Services’ Office for Civil Rights (OCR) Breach Portal. Any breach of protected health information that results in more than 500 records being exposed is investigated by OCR. During investigations of phishing attacks on healthcare organizations, OCR often finds that Health Insurance Portability and Accountability Act Rules have been violated. Healthcare organizations are discovered not to have performed risk assessments – as is required by the HIPAA Security Rule – and have failed to identify the risk of phishing and take appropriate steps to reduce risk to an acceptable level.

When organizations are found to have violated HIPAA Rules, heavy fines may follow. Recently, OCR has investigated several healthcare phishing attacks and has taken some cases forward to settlement. The HIPAA fines can be considerable.

In 2015, OCR announced its first HIPAA settlement for a phishing attack. University of Washington Medicine was fined $750,000 as a result of a malware installation that occurred when an employee responded to a phishing email. In that case, 90,000 patients had their information revealed to the attackers. A HIPAA penalty for a phishing attack was also announced last month, with the Colorado based Metro Community Provider Network (MCPN) having to pay OCR $400,000 to resolve HIPAA violations discovered during the investigation of the phishing attack. The phishing attack resulted in an email account being compromised, and along with it, the protected health information of 3,200 patients. The employee did not reveal their email credentials in that case, at least not directly. Instead, the response to the email resulted in a malware installation that gave the attacker access to the email account. Phishing attacks on healthcare organizations are to be expected. OCR is aware that it may not be possible to prevent 100% of phishing attacks, 100% of the time. Not all phishing attacks on healthcare organizations will therefore result in a HIPAA fine. However, failing to reduce risk to an acceptable level is another matter. If healthcare organizations do not do enough to prevent phishing attacks, fines are likely to result.

So, how can phishing attacks on healthcare organizations be prevented and what can healthcare organizations do to reduce risk to a level that will be deemed acceptable by OCR?  The HIPAA Security Rule requires protections to be put in place to safeguard the confidentiality, integrity, and availability of PHI. While the Security Rule does not specify exactly which security solutions should be used, there are two essential anti-phishing controls that should be employed.

A spam filtering solution should be used to prevent phishing and other malicious emails from being delivered to end users’ inboxes. It would be hard to argue that the threat from phishing has been reduced to an acceptable level if no controls are in place to block phishing emails from being delivered. Healthcare employees must also receive security awareness training. All employees should be informed of the risk of phishing and the methods used by cybercriminals to gain access to computers and data. They should be taught best practices and shown how to identify phishing emails and other malicious email threats. By blocking phishing emails and training end users, the risk from phishing can be significantly reduced.

Beware of WannaCry Phishing Emails

Cybercriminals have started sending WannaCry phishing emails, taking advantage of the fear surrounding the global network worm attacks.

An email campaign has been identified in the United Kingdom, with BT customers being targeted. The attackers have spoofed BT domains and made their WannaCry phishing emails look extremely realistic. BT branding is used, the emails are well written and they claim to have been sent from Libby Barr, Managing Director, Customer Care at BT. A quick check of her name on Google will reveal she is who she claims to be. The WannaCry phishing emails are convincing, cleverly put together, and are likely to fool many customers.

The emails claim that BT is working on improving its security in the wake of the massive ransomware campaign that affected more than 300,000 computers in 150 countries on May 12, 2017. In the UK, 20% of NHS Trusts were affected by the incident and had data encrypted and services majorly disrupted by the ransomware attacks. It would be extremely hard if you live in the UK to have avoided the news of the attacks and the extent of the damage they have caused.

The WannaCry phishing emails provide a very good reason for taking prompt action. BT is offering a security upgrade to prevent its customers from being affected by the attacks. The emails claim that in order to keep customers’ sensitive information secure, access to certain features have been disabled on BT accounts. Customers are told that to restore their full BT account functionality they need to confirm the security upgrade by clicking on the upgrade box contained in the email.

Of course, clicking on the link will not result in a security upgrade being applied. Customers are required to disclose their login credentials to the attackers.

Other WannaCry phishing emails are likely to be sent claiming to be from other broadband service providers. Similar campaigns could be used to silently download malware or ransomware.

Cybercriminals often take advantage of global news events that are attracting a lot of media interest. During the Olympics there were many Olympic themed spam emails. Phishing emails were also rife during the U.S. presidential elections, the World Cup, the Zika Virus epidemic, and following every major news event.

The golden rule is never to click on links sent in email from individuals you do not know, be extremely careful about clicking links from people you do know, and assume that any email you receive could be a phishing email or other malicious message.

A single phishing email sent to an employee can result in a data breach, email or network compromise. It is therefore important for employers to take precautions. Employees should be provided with phishing awareness training and taught the tell-tale signs that emails are not genuine.  It is also essential that an advanced spam filtering solution is employed to prevent the vast majority of phishing emails from reaching end users inboxes.

DocuSign Phishing Emails Sent to Account Holders Following Data Breach

A recent wave of DocuSign phishing emails has been linked to a data breach at the digital signature technology provider. A hacker gained access to a ‘non-core’ system that was used to send communications to users via email and stole users’ email addresses.

DocuSign reports that the peripheral system was compromised and only email addresses were accessed and stolen. No other data has been compromised as a result of the cyberattack. The data breach only affected DocuSign account holders, not registered users of eSignature.

It is currently unclear exactly how many email addresses were stolen, although the DocuSign website indicates the firm has more than 200 million users.

The attacker used customers’ email addresses to send specially crafted DocuSign phishing emails. The emails containing links to documents requiring a signature. The purpose of the emails was to fool recipients into downloading a document containing a malicious macro designed to infect computers with malware.

As is typical in phishing attacks, the DocuSign phishing emails appeared official with official branding in the headers and email body. The subject lines of the email were also typical of recent phishing campaigns, referring to invoices and wire transfer instructions.

The san Francisco based firm has been tracking the phishing emails and reports there are two main variations with the subject lines: “Completed: docusign.com – Wire Transfer Instructions for recipient-name Document Ready for Signature,” or “Completed *company name* – Accounting Invoice *number* Document Ready for Signature.”

The emails have been sent from a domain not linked to DocuSign – a sign that the emails are not genuine. However, due to the realism of the emails, many end users may end up clicking the link, downloading the document and infecting their computers.

Recipients are more likely to click on links and open infected email attachments if they relate to a service that the recipient uses. Since DocuSign is used by many business users, there is a significant threat of a network compromise if end users open the emails and follow the instructions provided by the threat actors.

Businesses can reduce the risk of malicious emails reaching end users inboxes by implementing an advanced spam filtering solution such as SpamTitan. SpamTitan blocks 99.97% of spam emails and 100% of known malware using dual antivirus engines for maximum protection.

Fatboy Ransomware – A New RaaS That Sets Ransoms by Location

A new email-borne threat has recently been discovered. Fatboy ransomware is a new ransomware-as-a-service (RaaS) being offered on darknet forums in Russia. The RaaS offers would-be cybercriminals the opportunity to conduct ransomware campaigns without having to develop their own malicious code.

RaaS has proven incredibly popular. By offering RaaS, malicious code authors can infect more end users by increasing the number of individuals distributing the ransomware.  In the case of Fatboy ransomware, the code author is offering limited partnerships and is dealing with affiliates directly via the instant messaging platform Jabber.

Fatboy ransomware encrypts files using AES-256, generating an individual key for the files and then encrypting those keys using RSA-2048. A separate bitcoin wallet is used for each client and a promise is made to transfer funds to the affiliates as soon as the money is paid. By offering to deal directly with the affiliates, being transparent about the RaaS and offering support, it is thought that the code author is trying to earn trust and maximize the appeal of the service.

Further, the ransomware interface has been translated into 12 languages, allowing campaigns to be conducted in many countries around the world. Many RaaS offerings are limited geographically by language.

Fatboy ransomware also has an interesting new feature that is intended to maximize the chance of the victim paying the ransom demand. This RaaS allows attackers to set the ransom payment automatically based on the victim’s location. In locations with a high standard of living, the ransom payment will be higher and vice versa.

To determine the cost of living, Fatboy ransomware uses the Big Mac Index. The Big Mac Index was developed by The Economist as a method of determining whether currencies were at their correct values. If all currencies are at their correct value, the cost of a product in each country should be the same. The product chosen was a Big Mac. In short, the higher the cost of a Big Mac in the victim’s country, the higher the ransom demand will be.

So far, Recorded Future – the firm that discovered the ransomware variant – says the code author has generated around $5,000 in ransom payments since February. That total is likely to rise considerably as more affiliates come on board and more end users are infected. There is no known decryptor for Fatboy ransomware at this time.

New ransomware variants are constantly being developed and RaaS allows many more individuals to conduct ransomware campaigns. Unsurprisingly, the number of ransomware attacks has grown.

The cost of resolving a ransomware infection can be considerable. Businesses therefore need to ensure they have defenses in place to block attacks and ensure they can recover fast.

Backups need to be made regularly to ensure files can be easily recovered. Staff need to be trained on security best practices to prevent them inadvertently installing ransomware. Antispam solutions should also be implemented to prevent malicious emails from reaching end users’ inboxes. Fortunately, even with a predicted increase in ransomware attacks, businesses can effectively mitigate risk if appropriate defenses are implemented.

IC3 Issues Warning About Business Email Compromise Scams

The Internet Crime Complaint Center (IC3) has issued a new alert to businesses warning of the risk of business email compromise scams.

The businesses most at risk are those that deal with international suppliers as well as those that frequently perform wire transfers. However, businesses that only issue checks instead of sending wire transfers are also at risk of this type of cyberattack.

In contrast to phishing scams where the attacker makes emails appear as if they have come from within the company by spoofing an email address, business email compromise scams require a corporate email account to be accessed by the attackers.

Once access to an email account is gained, the attacker crafts an email and sends it to an individual responsible for making wire transfers, issuing other payments, or an individual that has access to employees PII/W-2 forms and requests a bank transfer or sensitive data.

The attackers often copy the format of emails previously sent to the billing/accounts department. This information can easily be gained from the compromised email account. They are also able to easily identify the person within the company who should be sent the request.

Not all business email compromise scams are concerned with fraudulent bank transfers. IC3 warns that the same scam is also used to obtain the W-2 tax statements of employees, as has been seen on numerous occasions during this year’s tax season.

Phishing scams are often sent out randomly in the hope that some individuals click on malicious links or open infected email attachments. However, business email compromise scams involve considerable research on the company to select victims and to identify appropriate protocols used by the company to make transfer requests.

Business email compromise scams often start with phishing emails. Phishing is used to get end users to reveal their login credentials or other sensitive information that can be used to gain access to business networks and perform the scam. Malware can also be used for this purpose. Emails are sent with links to malicious websites or with infected email attachments. Opening the attachments or clicking on the links downloads malware capable of logging keystrokes or provides the attackers with a foothold in the network.

IC3 warns that business email compromise scams are a major threat for all businesses, regardless of their size. Just because your business is small, it doesn’t mean that you face a low risk of attack.

Between January 2015 and December 2016, IC3 notes there was a 2,370% increase in BEC scams. While funds are most commonly sent to bank accounts in China and Hong Kong, IC3 says transfers have been made to 103 countries in the past two years.

The losses reported by businesses are staggering. Between October 2013 and December 2016, more than $5 billion has been obtained by cybercriminals. United States businesses have lost $1,594,503,669 in more than 22,000 successful scams. The average loss is $71,528.

IC3 lists the five most common types of business email compromise scams as:

  1. Businesses receiving requests from frequently used suppliers requesting transfers be made to a new bank account.This is also known as a bogus invoice scam.
  2. An executive within the company (CFO or CTO for example) requests a transfer be made by a second employee in the company. This is also known as a business executive scam.
  3. A compromised email account is used to send a payment request/invoice to a vendor in the employees contact list.
  4. The attackers impersonate an attorney used by the firm and request the transfer of funds. These scams are common at the end of the week or end of the business day. They are also known as Friday afternoon scams.
  5. A request is sent from a compromised email account to a member of the HR department requesting information on employees such as W-2 Forms or PII. These scams are most common during tax season.

There are a number of strategies that can be adopted to prevent business email compromise attacks from being successful.

IC3 recommends:

  • Using a domain-based email account rather than a web-based account for business email accounts
  • Exercising caution about the information posted to social media accounts. This is where the attackers do much of their research
  • Implement a two-step verification process to validate all transfer requests
  • Use two-factor authentication for corporate email accounts
  • Never respond to an email using the reply option. Always use forward and type in the address manually
  • Register all domains that are similar to the main domain used by the company
  • Use intrusion detection systems and spam filters that quarantine or flag emails that have been sent with extensions similar to those used by the company – Blocking emails sent from xxx_company.com if the company uses xxx-company.com for example
  • Be wary of any request that seems out of the ordinary or requires a change to the bank account usually used for transfers

Millions Affected by Google Phishing Scam

A Google phishing scam has been spreading like wildfire over the past couple of days. Emails have been sent in the millions inviting people to edit Google Docs files. The emails appear to have been sent by known individuals, increasing the likelihood of the messages being opened and the links being clicked.

In contrast to many email scams that include a link to a spoofed website, this scam directs the recipient to Google Docs. When the user arrives at the site they will be presented with a legitimate Google sign-in screen.

The Google phishing scam works within the Google platform, taking advantage of the fact that individuals can create a third-party app and give it a misleading name. In this case, the app has been named ‘Google Docs.’

This makes it appear that Google Docs is asking for permission to read, send, delete, and manage emails and access the user’s contacts. However, it is the creator of the app that is asking to be granted those permissions. If users check the developer name, they will see that all is not as it seems. Many individuals will not check, since the permission screen also includes Google logos.

Signing in will give the attacker access to the user’s Google account, including their emails, Google Docs files, and contact list. Further, signing in on the website will also result in the victim’s contact list being sent similar invitations. Unsurprisingly, many have fallen for the Google phishing scam and countless emails are still circulating.

The scam appears to have started at some point on Wednesday. Google has now issued an official statement saying it is taking action to protect users and has disabled the accounts that are being used to conduct the scam.

Google confirmed the actions it has taken in response to the phishing scam, saying “We’ve removed the fake pages, pushed updates through Safe Browsing, and our abuse team is working to prevent this kind of spoofing from happening again. We encourage users to report phishing emails in Gmail.”

Anyone who receives a request to edit a Google Doc should treat the request with suspicion, even if it has been sent from someone known to the recipient.

If you think you may have fallen for this phishing scam it is likely that emails will already have been generated and sent to your contacts. However, you can take action to block the threat by revoking the access rights you have given to the app through the Connected Apps and Sites page.

The Google phishing scam is highly convincing and clearly shows how sophisticated cybercriminals are getting in their attempts to gain access to sensitive information and why it is imperative that email users be permanently on their guard.
