Reports of Internet users that have been caught out by email scams continue to increase. Whether it is drivers being told to pay speeding fines via a link on an email, or Facebook users being advised that they have violated the terms of their account, innocent victims continue to be ripped off by cybercriminals using email scams.
Business email compromise scams are also reported to have increased. These email scams involve the cybercriminal gaining access to a corporate email account – such as that of the CEO. An email is then sent apparently from the CEO to a member of the finance department requesting a bank transfer to the cybercriminal´s account. All too often the transfer is made without question.
Many email scams attempt to extract log-in credentials by asking the recipient of the email to log into an account to resolve an issue. The email contains a link to a bogus website, where the recipient keys in their username and password. In the case of the Facebook email scam, this gives the cybercriminal access to the recipient´s genuine account and all their social media contacts.
Many individuals use similar username and password combinations for multiple accounts and a cybercriminal could get the individual´s log-in credentials to all their online accounts (personal and work accounts) from just one scam email. Alternatively they could use the log-in credentials to infect the user´s accounts with malware.
To protect against email scams, security experts advise if you are contacted by email and asked to click a link, pay a fine, or open an attachment, assume it is a scam. Try to contact the individual sender or company supposed to have sent the email to confirm its authenticity. Do not use the contact information supplied in the email. Perform an Internet search to independently obtain the sender´s genuine contact details.
Other measures that can be taken to protect yourself from email scams include:
- Carefully check the sender’s email. Does it look like it is genuine?
- Never open email attachments from someone you do not know
- If you receive an email offering you a prize or refund, stay safe and delete the email
- Ensure anti-virus software is installed on your computer and is up to date.
In the United Kingdom and Eire, homebuyers and sellers are being targeted by cybercriminals using a new solicitor email scam. The scam, which involves mimicking a solicitor, is costing victims thousands. There have also been some reported cases of cybercriminals sending solicitors emails claiming to be their clients and requesting changes of bank details. Any pending transfers are then made to the criminals’ accounts.
Since funds for home purchases are transferred to solicitors’ accounts before being passed on to the sellers, if cybercriminals are able to change the bank details for the transfers, the funds for the purchase will be paid directly into their accounts.
While email spoofing is commonplace, this solicitor email scam often involves the hacking of solicitors’ email accounts. Once access has been gained, cybercriminals search for emails sent to and from buyers and sellers of homes to identify potential targets. While the hacking of email accounts is occurring, there have also been instances where emails between buyers, sellers, and their solicitors have been intercepted. When bank details for a transfer are emailed, the hackers change the bank information in the email to their own and then forward the email on.
The solicitor email scam is highly targeted and communications are monitored until the crucial point in the purchasing process when a bank transfer is about to be made. Since the potential rewards are considerable, cybercriminals are willing to put the time and effort into the scam and be patient. Buyers, sellers, and solicitors are well researched and the emails are highly convincing.
Instances of this conveyancing scam have been increasing in recent months and it has now become the most common cybercrime affecting the legal sector. The Law Society, a representative body for solicitors in the UK, has issued a warning about the conveyancing scam due to an increased number of complaints, although it is currently unclear how many fraudulent transfers have been made.
There is of course an easy way for solicitors to prevent such a scam from being successful, and that is to contact the homebuyer or seller before any transfer is made and to verbally confirm the bank details by telephone. Alternatively, policies can be developed requiring bank account information to only be sent via regular mail.
The Solicitors Regulation Authority advises against the use of email for property transactions due to the potential for cybercriminals to intercept and spoof messages. Email may be convenient, but with such large sums being transferred it pays to exercise caution.
While this solicitor email scam is common in the UK and Eire, legal firms in the United States should also exercise caution. Since the conveyancing scam is proving to be lucrative, it will only be a matter of time before U.S. lawyers are targeted.
Cyberattacks on law firms have been steadily increasing over the past three years. According to data from PwC’s annual Law Firms Survey last year, 73% of the UK’s top 100 law firms have been attacked by cybercriminals in the past year. In 2014/2015, 62% of the top 100 law firms were attacked. The previous year the figure stood at 45%. In the past two years, cyberattacks on law firms have increased by a staggering 60%.
According to PwC’s figures, large law firms are the most frequently targeted. 90% of the top 25 legal firms had experienced a cyberattack in the past 12 months. The types of attacks are highly varied, although the most common way attacks occur is via the firm’s email system.
Spear phishing emails are sent to solicitors in an attempt to obtain banking credentials and access to email accounts. When solicitors respond to these phishing emails and divulge their banking credentials, client funds are transferred to the criminals’ accounts. According to the survey, 84% of legal firms said they had experienced a phishing attack in the past year.
Solicitors in the UK and Ireland and attorneys in the United States are also being sent bogus emails that claim to be from home buyers or sellers. Instructions are provided asking for funds to be transferred to alternate accounts. Hackers eavesdrop on email conversations and are aware when funds are about to be transferred. They then sent an email to an attorney/solicitor posing as the buyer/seller of a property and provide alternate bank accounts asking for the funds to be transferred to the new account.
Buyers and sellers of properties are also targeted in a similar fashion. They are sent emails with the hacker claiming to be their solicitor. Alternate bank account details are provided for transfers. This is now one of the main types of cyberattacks on law firms and their clients.
Direct attacks on networks still occur, with hackers taking advantage of vulnerabilities in security defenses. However, law firm hacking only accounts for around 16% of incidents. Malware is a much bigger threat. Malware is delivered via spam email or drive-by downloads from the Web. 55% of legal firms say they have experienced a malware attack in the past 12 months. Malware can be ransomware – which locks computers with powerful encryption until a ransom payment is made or keyloggers that record sensitive data such as usernames and passwords. Malware can also enable criminals to gain access to systems to steal sensitive data and extort money out of law firms.
Law firm cyberattacks can be costly to resolve; however, the biggest cost can be loss of reputation. If law firms suffer cyberattacks and client data is stolen or exposed, reputations can be permanently damaged. Legal firms that are unable to ensure that their clients’ information remains confidential may find the cost of removing malware the least of their problems.
To prevent phishing emails and malware from being delivered to inboxes, an advanced spam filter is required. SpamTitan includes a powerful anti-phishing component that recognizes the common signatures of phishing emails and ensures they are not delivered. SpamTitan also blocks 100% of known malware and ransomware, ensuring end users do not receive malicious email attachments and links to malware-ridden websites.
To find out how SpamTitan can improve your security posture, contact the TitanHQ team today and take the first step toward preventing your law firm from being added to next year’s PwC’s law firm cyberattack statistics.
Anti-phishing training can help an organization improve its security posture. However, even with training on phishing email identification, employees still fail to spot many email scams. Anti-phishing training alone is insufficient to prevent successful phishing attacks.
The Threat from Phishing is Growing
Your business is likely to be bombarded with phishing emails, especially at this time of year. Tax season sees millions of emails sent to businesses by cybercriminals who want access to employees’ W-2 Forms. However, phishing is a year-round problem. It has been estimated that an astonishing 156 million phishing emails are now being sent every single day.
As we have already seen this year, phishing scams can be highly convincing. Many businesses have discovered employees have responded to these scams in the belief that the email requests are genuine. The cost of those phishing attacks can be considerable for businesses, their customers and their employees.
Anti-Phishing Training Alone will Not Prevent Successful Phishing Attacks
To ensure employees are prepared, many businesses provide employees with anti-phishing training. They teach staff members how to identify phishing scams and the tell-tale signs that email requests are not genuine.
How effective is anti-phishing training? A recent analysis by Diligent showed that the average score on its phishing test was 76%. That means employees are failing to identify phishing scams 24% of the time and all it takes is one response to a phishing email for an employee’s email account to be compromised, a network login to be handed to cybercriminals, or the W-2 Forms of an entire workforce to be emailed to tax fraudsters.
Fortunately, as PhishMe’s data shows, with practice, employees get much better at identifying phishing emails. Providing training and conducting follow up tests using dummy phishing emails helps to show where training has failed. This allows organizations to provide further training to employees whose phishing email identification skills are poor. However, even with training and testing it will never be possible to ensure that 100% of employees identify 100% of phishing emails 100% of the time.
The Best Phishing Defense is to Prevent Phishing Emails from Being Delivered
Training should be provided and employees’ anti-phishing skills should be tested with dummy phishing exercises, but organizations should ensure that phishing emails are not delivered to end users’ inboxes. That means an advanced, powerful spam filtering solution is required.
SpamTitan blocks 99.97% of spam emails from being delivered. SpamTitan also includes a powerful anti-phishing component to block phishing attacks. However, blocking potentially malicious emails is only part of the story. It is also important to choose a solution that does not prevent genuine emails from being delivered.
Independent tests by VB Bulletin confirm SpamTitan has a consistently low false positive rate. Only 0.03% of genuine emails trigger SpamTitan’s anti-spam filters. The excellent catch rates and low false positives have seen SpamTitan win 36 consecutive VB Bulletin Anti-Spam Awards.
SpamTitan is available as a gateway appliance or a cloud-based solution, with both requiring minimal IT support. To suit the needs of service providers, the cloud-based version is available in a private cloud and is supplied in white-label format ready for rebranding.
The cost-effective solution is easy to implement, use and maintain and can be used to protect a limitless number of email accounts.
If you want to keep your employees’ inboxes free from phishing emails, malware, and ransomware, call the TitanHQ Sales Team today and say a fond farewell to email spam.
Another school phishing email attack has resulted in the W-2 Form data of school employees being emailed to tax fraudsters. This time, it was employees of Mercer County Schools in West Virginia whose data have been compromised.
The FBI has been called in to investigate the W-2 phishing scam and the IRS has been notified of the incident, while affected employees have been offered services to help them protect their identities.
The school phishing email attack is just one of many such attacks that have occurred this year. While businesses have been extensively targeted in the past, phishing attacks on schools are now commonplace. The problem has become so severe that the IRS recently issued a warning to schools of the risk of phishing email attacks, saying “This is one of the most dangerous email phishing scams we’ve seen in a long time.”
The Mercer County School District phishing attack was almost a carbon copy of many other tax season attacks this year. Already, there have been more than 29,000 victims of these attacks and there is still two months of tax season remaining.
The school phishing email attack involved the sending of an email to an employee in the HR/payroll department requesting a copy of W-2 Forms for all employees that worked in the previous fiscal year. The email was sent from an email account that was very similar to that used by the chief supervisor.
The email contained a slight variation from the genuine email address, which was enough to fool the recipient into thinking the email had been sent from the supervisor’s account. The employee then sent the W-2 forms of 1,800 staff members to the attackers as requested.
Databreaches.net has been tracking this year’s W-2 phishing scams and is maintaining a list of all organizations that have been scammed into revealing W-2 Form data. The list shows that school districts are being extensively targeted. Successful W-2 phishing attacks have been reported by the following schools and school districts in the past 6 weeks:
- Argyle School District, TX
- Belton Independent School District, TX
- Bloomington Public Schools, MN
- College of Southern Idaho, ID
- Davidson County Schools, NC
- Dracut Schools, MA
- Lexington School District 2, SC
- Manatee County School District, FL
- Mohave Community College, AZ
- Morton School District, IL
- Odessa School District, WA
- Tipton County Schools, TN
The Manatee County School District phishing attack resulted in the W-2 Form data of 7,900 employees being emailed to the scammers: The biggest school phishing email attack of the year to date. The Bloomington Public Schools attack also resulted in thousands of employees’ W-2 Forms being disclosed.
There are a number of measures that can be taken to reduce the risk of phishing attacks such as these. Training should be provided to HR and payroll staff and they should be instructed to carefully check senders’ email addresses to ensure the correct account has been used. Policies should also be developed requiring any W-2 Form requests to be verified with the sender via the telephone. It is also essential to implement a spam filtering solution with a powerful anti-phishing component. This will help to ensure that the emails are not delivered. A spam filtering solution will also block malware and ransomware emails from being delivered. The latter types of malicious emails have also been a major problem for school districts over the past year.
Spammers and scammers are constantly updating their malware distribution tactics to ensure their malicious payloads are delivered to unsuspecting end users. However, Microsoft has spotted a major change to malware distribution tactics used by cybercriminals. The change has prompted the software giant to issue a new warning.
Malware, including ransomware, is commonly distributed via spam email. Links to malicious websites are used in an attempt to bypass spam filter controls; however, malicious attachments are the delivery mechanism of choice for many cybercriminal gangs. Malicious links are commonly blocked by web filtering solutions – WebTitan for example prevents all users from visiting websites known to be malicious.
To bypass spam filter controls, attachments rarely include the actual malware or ransomware files, instead the files contain scripts that download the malicious payload.
Due to the ease at which these malicious downloaders are being identified, malware distribution tactics have been changed. Rather than use these suspect files, cybercriminals have switched to file types that are less obviously malicious. Microsoft has noticed a trend for using LNK files and SVG files containing malicious PowerShell scripts.
LNK files are Windows shortcut files which usually point to some form of executable file. SVG (Scalable Vector Graphics) files are image files, and are much more innocuous. These files are typically opened with image software such as Adobe Creative Suite or Illustrator. Double clicking on these malicious LNK and SVG files will launch PowerShell scripts that download malware or ransomware.
Protecting against these types of attacks may seem fairly straightforward. It is possible, for example, to set restrictions on PowerShell commands to prevent them from running. However, even with restrictions in place, those policies can be easily bypassed. Intel Security has recently explained one such method: “PowerShell’s Get-Content can access the content of a .ps2 malware script and pass it to Invoke-Expression (iex) for execution.”
Ransomware attacks on British schools have soared in recent weeks. The problem has become so serious that the British National Fraud and Cyber Crime Reporting Center, also known as Action Fraud, has issued a new ransomware warning to British schools.
Ransomware has grown in popularity with cybercriminals over the past 2 years, with attacks on organizations around the world soaring in 2016. 2017 may only be a few weeks old, but ransomware attacks are continuing at the high levels seen in 2016. Security experts predict that 2017 will see even more cyberattacks on schools and other educational institutions. Ransomware the attack method of choice.
Ransomware is a form of malware that encrypts data on a compromised system. A wide range of file types are locked with powerful encryption and a ransom demand is issued. If payment is made, the attackers claim they will supply the key to unlock the encryption. Without the key – the sole copy is held by the attackers – data will remain locked forever.
Some forms of ransomware have been cracked and free decryptors made available, but they number in the few. The majority of ransomware variants have yet to be cracked. Recovery depends on payment of the ransom or the wiping of the attacked system and restoration of files from backups.
While a standard charge per encrypted device was the norm early last year, ransomware is now more sophisticated. The attackers are able to set their payment demand based on the types of files encrypted, the extent of the infection, and the perceived likelihood of the victim paying up. Ransomware attacks on British schools have seen ransom demands of an average of £8,000 issued.
Ransomware Attacks on British Schools are Targeted, Not Random
Many ransomware attacks are random – Spam emails are sent in the millions in the hope that some of them reach inboxes and are opened by employees. However, ransomware attacks on British schools have seen a different approach used. Recent attacks have been highly targeted.
Rather than send emails out en masse, the spate of recent ransomware attacks on British schools start with a phone call. In order to find their target, the attackers call the school and ask for the email address of the head teacher. The email address is required because sensitive information needs to be sent that should only be read by the head teacher. Information such as mental health assessment forms and teacher guidance forms.
An email is then crafted and sent to the head teacher; addressed to that individual by name. While there are many types of ransomware emails, a number of recent ransomware attacks on British schools involved an email that appears to have been sent by the Department of Education. Other cases have involved the impersonation of the Department of Work and Pensions and telecom providers.
In the text of the email the attacker explains that they have sent some information in an attached file which is important and needs to be read. The attached file, usually in compressed format such as .ZIP or .RAR, contains files that install ransomware if opened.
How to Prevent Ransomware Attacks
Ransomware attacks on British schools can be highly sophisticated, although risk can be effectively mitigated.
- Ensure all staff with computer access are made aware of the risk of ransomware attacks
- Provide cybersecurity training to all staff, including how to identify ransomware and phishing emails
- Never open attachments or visit links in emails sent from unknown senders
- Implement a spam filter to capture and quarantine malicious spam emails
- Use a web filtering solution to prevent staff members from visiting malicious links and from downloading ‘risky’ files
- Ensure all software is kept up to date and patches are applied promptly
- Keep all anti-virus and anti-malware solutions up to date, setting updates to occur automatically
- Restrict the use of administrator accounts – Only use accounts with high levels of privileges for specific tasks
It is also essential to ensure that backups of all data are made on a daily basis and backup devices are disconnected after backups have been performed. Data should ideally be backed up to the cloud and on a physical backup device. In the event of an attack, data can then be recovered without paying the ransom.
University phishing scams targeting students have increased in recent months. Targeting some of the most well educated individuals may not appear to be the most rewarding strategy for scammers, but students are falling for these university phishing scams in their droves.
University Phishing Scams are Becoming Difficult to Identify
Awareness of phishing tactics has certainly improved thanks to educational programs, email warnings, and media coverage of phishing attacks, but in response, cybercriminals have got better at scamming. Today, phishing emails can be difficult to identify. In fact, in many cases, it is virtually impossible to tell a genuine email from a scam.
While students may be aware of the risks of clicking links in emails from unknown senders, the same cannot be said when the emails are sent from a contact. Emails from university IT departments, professors and colleagues are likely to be opened. Students’ guard is let down when the sender of the email is known.
When a convincing request is included, students often respond and have no idea that they have been scammed into revealing their login credentials or disclosing other sensitive information. All it takes is for one email account of a student to be compromised to start the process. Emails are then sent to that individual’s email address book. A number of those contacts respond. The same happens with their contacts and so on. Given that there are supposedly six degrees of separation between all individuals on the planet, it is easy to see how fast malware infections can spread and how multiple email accounts can be compromised rapidly.
University phishing scams have been increasing for some time, although the past few months have seen even more scams emails sent. Recently, the University of Connecticut sent warnings out to students following a spate of phishing scams. Some of those scams involved the impersonation of the University president. Students at the University of Georgia have also been targeted.
In the case of the latter, one student’s email account was compromised after she responded to a phishing email sent from UGA associate. The email did not arouse any suspicions because the contact was known. In the email the student was told that it was important for her to change her password. Failure to do so would result in her being locked out of her email account. She responded by clicking the link and changing her password. However, what she had done was disclose her old password and her new one to the attacker.
The attacker then used those credentials to set up a mail forwarder on the email account. The student only found out after querying why she was no longer receiving emails with the IT help desk. After investigating, the mail forwarder was discovered.
Other students were similarly targeted and their emails accounts were used to send out huge volumes of spam emails. It was only when spamming complaints were received about the compromised accounts that the problem was identified.
These university phishing scams are conducted for a wide range of nefarious purposes. Spamming and mail forwarders may cause limited harm, but that may not always be the case. Malware infections can result in serious financial harm to students and universities. Ransomware installations can occur after students respond to phishing campaigns, and those attacks can cost tens of thousands of dollars to resolve.
How to Protect Students and Networks from the Scammers
Since these phishing scams are now so hard to identify, training on email and cybersecurity best practices is no longer as effective as it once was. Technological solutions are therefore required to prevent emails from being delivered and to stop end users from being directed to malicious websites.
SpamTitan is an ideal spam filtering solution for universities. SpamTitan blocks 99.97% of spam emails and 100% of known malware. The solution is cost effective to install, easy to administer, and no additional hardware is required or any software updates necessary.
When used in conjunction with WebTitan – TitanHQ’s powerful web filtering solution –all attempts to visit malicious links and known phishing websites can be blocked.
Both solutions are available on a 30-day no obligation free trial. If you want to ensure your students and university networks are properly protected, contact the TitanHQ sales team today to register for the trials and discover the difference that each solution can make.
Sophisticated phishing emails and elaborate web-based scams are being used to target students at the University of Connecticut. The extent to which students have been targeted with these scams has prompted UConn Chief Information Officer and Provost for Information Technology to send a warning to all students to be on high alert.
A number of students at the university have received sophisticated phishing emails in recent months that appear to have been sent from University President Susan Herbst. Like many universities and other educational establishments, the email system is protected with a spam filter. The majority of spam and scam emails are filtered out, although some do make it through. If these emails are delivered to students, there is a high probability that they will be opened. After all, the messages do appear to have been sent from the University president.
The emails contain malicious attachments or links to websites that attempt to steal login information and the scam is sophisticated and highly convincing. Many students would be unaware that they have been scammed after disclosing their login credentials.
The same can be said of malware infections, which usually occur silently when a malicious website is visited. Criminals are attempting to install key-loggers that record all sensitive data entered on compromised computers.
These scams are intended to get students to disclose their bank account information, credit card data, or Social Security numbers and personal information. The attackers can then use this information for a wide range of nefarious purposes including identity theft.
Sophisticated Phishing Emails are the New Norm
Email scams of old were quite easy to identify. They often included many grammatical and spelling mistakes and included offers that sounded too good to be true. However, today, sophisticated phishing emails are the new norm and they can be very difficult to identify. Emails are sent from authority figures, are grammatically perfect, and the attackers use wide range of social engineering techniques to get victims to disclose sensitive data or take a particular action.
The scammers are also increasingly sending highly targeted emails. These ‘spear phishing’ emails use personal information unique to the recipient to add credibility. Information is often obtained from social media and professional networking sites.
One of the latest UConn email scams includes information about Blackboard Inc., the Mail Service used by UConn. The attachment has the title “Exclusive Important Announcement from President Susan Herbst.”
Warnings have been issued by email to all students alerting them to this scam and advising them to exercise caution when using email and surfing the Internet. Students have been told not to login on any websites that do not have a valid security certificate.
A Spam Filter and Web Filter in Tandem Offer Greater Protection Against Phishing Attacks
Users should always exercise caution when using email. Attachments from unknown senders should not be opened and links contained in emails from unfamiliar sources should not be visited. However, curiosity often gets the better of students and malicious links are often unwittingly visited.
For this reason, in addition to using an advanced spam filtering solution – such as SpamTitan – universities and other educational establishments should also employ a web filtering solution. The spam filter will block the vast majority of malicious messages. The web filter will ensure that malicious websites and infected webpages cannot be visited. In tandem, a spam filter and web filter will offer far greater protection against phishing attacks and malware/ransomware infections.
A W-2 Form phishing scam that has been extensively used to con businesses out of the tax information of their employees is now being used on educational institutions. School districts need to be on high alert as cybercriminals have them fixed in their cross-hairs.
Over the past few weeks, many school districts have fallen victim to the scammers and have disclosed the W-2 Form data of employees. Teachers, teaching assistants, and other members of school staff have had their Social Security numbers and earnings information sent to fraudsters. The data are used to file fraudulent tax returns in victims’ names.
At face value, the W-2 Form phishing scam is one of the simplest con-tricks used by cybercriminals. It involves sending an email to a member of the HR or payroll team asking for the W-2 Forms of all employees to be sent via email. Why would any employee send this highly sensitive data? Because the email appears to have been sent from individuals within the school district who have a genuine need for the information. This is why the W-2 Form phishing scam is so effective. In many cases, suspicions are not aroused for a number of days after the emails have been sent. By that time, fraudulent tax returns may have been filed in the names of all of the victims.
It is unknown how many school districts have been targeted to date with this W-2 Form phishing scam, although 10 school districts in the United States have announced that their employees have fallen for the scam this year and have emailed W-2 Form data to the attackers. In total, 23 organizations have announced that an employee has fallen for a W-2 Form phishing scam in 2017, and at least 145 organizations fell for similar scams last year.
Due to the number of attacks, the IRS issued a warning in early 2016 to alert all organizations to the threat. The increase in attacks in 2017 has prompted the IRS to issue a warning once again. While corporations are at risk, the IRS has issued a warning specifically mentioning school districts, as well as non-profits and tribal organizations.
The IRS warning explains how cybercriminals have started even earlier this year. While the W-2 Form phishing scam emerged last year, many attacks occurred relatively late in the tax season. Cybercriminals are attempting to get the data sooner this year. The sooner a fake tax return is filed, the greater the chance that a refund will be issued.
A variety of spoofing techniques are employed to make the email appear like it has come from the email account of an executive or other individual high up in the organization. In some cases, criminals have first compromised the email account of a board member, making the scam harder to identify.
This year has also seen a new twist to the scam with victims targeted twice. In addition to the W-2 Form scam, the victims are also subjected to a wire transfer scam. After W-2 Forms have been sent, a wire transfer request is made to the payroll department. Some organizations have been hit with both scams and have disclosed employees’ tax information and then made a wire transfer of several thousand dollars to the same attackers.
Protecting against these scams requires a combination of technology, training and policy/procedural updates. The first step for all organizations – including school districts – is to send an email to all HR and payroll staff warning them about these phishing scams. Staff must be made aware of the scam and told to be vigilant.
Policies and procedures should be updated requiring payroll and HR staff to authenticate any email request for W-2 Form data by telephone prior to sending the information.
An advanced spam filter – such as SpamTitan – can also greatly reduce the risk of W-2 Form scam emails being delivered to end users’ inboxes. Blocking suspicious emails will reduce reliance on training and user awareness of these scams. The spam filter will also be effective at blocking further scams and other malicious emails from being delivered.
Osiris ransomware is the latest variant of Locky. As with other versions of the ransomware, there is no free way of unlocking encrypted files if a viable backup of data does not exist.
Cybercriminals use a variety of techniques and attack vectors to spread malicious files such as ransomware and malware. Exploit kits are popular as they can be hidden on websites and used to silently probe visitors’ browsers for vulnerabilities in plugins such as Adobe Flash, Microsoft Silverlight, and Oracle Java. Those vulnerabilities are leveraged to download malware. Malvertising – malicious web adverts – are often used to direct users to these malicious webpages; however, all too often, links to these websites are sent via spam email.
The rise in malware and ransomware attacks over the past few years has prompted many organizations to start providing security awareness training to staff members. Employees are instructed never to click on a link contained in an email unless they are sure that it is genuine.
However, even with security awareness training, a great many employees inadvertently infect their computers with malware or accidentally download ransomware. One of the biggest problems is not malicious links in spam email but malicious attachments. Cybercriminals have increased the use of malicious file attachments in the last year, especially to infect end users with ransomware.
One of the biggest ransomware threats in the past 12 months has been Locky. Locky has been spread via exploit kits in the past, although spam email is now primarily used to infect users.
Office Macros Used to Infect Computers with Osiris Ransomware
The gang behind Locky frequently updates the ransomware, as well as the methods used to fool end users into installing the malicious file-encryptor. The latest Locky variant – Osiris ransomware – encrypts files and adds the .osiris extension to encrypted files.
Locky is commonly spread via malicious macros in Word documents. Typically, the malicious Word documents claim to be invoices, purchase orders, or notifications of missed parcel deliveries.
However, a recent campaign used to distribute the Osiris ransomware variant switches from .DOC files to Excel spreadsheets (.XLS). Recipients of the emails are told the Excel spreadsheet is an invoice. Opening the attached Excel spreadsheet will not automatically result in an Osiris ransomware infection if macros have not been set to run automatically. The user will be presented with a blank spreadsheet and a prompt to enable macros to view the content of the file.
Clicking on ‘Enable Content’ will launch a VBA script that downloads a Dynamic Link Library (DLL) file, which is automatically executed using the Windows file Rundll32.exe. That DLL file is used to download Osiris ransomware. Osiris ransomware encrypts a wide range of file types and deletes Windows Shadow Volume Copies, preventing the user from restoring the computer to the configuration before the ransomware was installed. The only option for recovery from an Osiris ransomware infection is to pay the ransom demand or to wipe the system and restore files from backups.
Protecting Networks From E-Mail-Based Ransomware and Malware Attacks
An advanced spam filtering solution such as SpamTitan can be used to block the vast majority of email-borne threats. SpamTitan performs a wide range of front line tests to rapidly identify spam email and prevent it from being delivered, including RBL, SPF, Greylisting and SMTP controls.
SpamTitan uses two enterprise-class anti-virus engines to scan for malicious attachments – Kaspersky Anti-Virus and ClamAV – to maximize detection rates.
Host-based tests are performed to examine mail headers, while the contents of messages are subjected to a Bayesian analysis to identify common spam signatures and spam-like content. Messages are also scanned for malicious links.
These extensive tests ensure SpamTitan blocks 99.97% of spam emails, preventing malicious messages from being delivered to end users. SpamTitan has also been independently tested and shown to have an exceptionally low false positive rate of just 0.03%.
If you want to keep your network protected from malicious spam emails and reduce reliance on employees’ spam detection abilities, contact the TitanHQ team today. SpamTitan is available on a 30-day free trial, allowing you to fully test the product and discover the difference SpamTitan makes at your organization before committing to a purchase.
Its tax season in the United States, which means the start of scamming season. W2 phishing scams and other tax-related email and telephone scams are rife at this time of year. Businesses need to be particularly careful. There have already been a number of victims of W2 phishing scams and the year has barely started.
2016 Saw a 400% Rise in Tax Season Phishing and Malware Incidents
Tax season in the United States runs from the start of January to April 15. It is the time of year when Americans calculate how much tax they need to pay from the previous financial year. It is also a busy time for cybercriminals. They will not be filing their own tax returns however. Instead they are concentrating on filing tax returns on behalf of their victims.
In order for tax refunds to be fraudulently filed, cybercriminals need information about their victims. Given the number of data breaches that have resulted in the theft of Social Security numbers in the past 12 months, 2017 could well be a record year for tax scams.
However, while past data breaches can provide cybercriminals with the information they need to file fraudulent tax returns, tax season usually sees a massive increase in phishing scams. The sole purpose of these scams is to get victims to reveal their Social Security numbers and the other personal information necessary to file tax returns.
Since the IRS started allowing Americans to e-file their tax returns, scammers had a new option for filing fraudulent tax returns. Phishing emails claiming to have been sent by the IRS request the recipients update their IRS e-file. A link is included in the emails for this purpose. Clicking on the link in the emails will not direct the recipient to the IRS website, but a spoofed version of the site. The information entered online is then used to e-file on behalf of the victims and the scammers pocket the tax refunds.
In 2016, the IRS reported a massive increase in phishing and malware incidents. These scams and malware infections increased by an incredible 400%. The massive rise in scams prompted the IRS to issue a warning to Americans about the scams, with the IRS confirming that it does not initiate contact with taxpayers by email to request personal or financial information.
2017 is likely to be no different. Until April 15, tax-related scams are likely to be rife. All Americans should therefore be wary and must exercise caution.
Tax Season Sees a Massive Rise in W2 Phishing Scams
While consumers are at risk. Businesses in the United States are also extensively targeted at this time of year. The scammers impersonate CEOs, CFOs, and other individuals with authority and make requests for W2 data and other financial information about employees. The requests can be highly convincing and each year many employees fall for these types of scams. The scammers are well aware that some employees would be nervous about questioning a request that has been emailed from their SEO or CFO.
It is difficult to determine how many attempted W2 phishing scams took place last year, but in the first quarter of 2016, at least 41 U.S companies reported that they were the victims of successful W2 phishing scams. Employees were sent email requests to send W2 data by return and they responded. By doing so, employees’ tax information was sent directly to the scammers’ inboxes.
2017 is not yet a month old, yet already W2 phishing scams have been reported. The week, the Tipton County Schools District in western Tennessee reported that it had fallen victim to one of these W2 phishing scams. The attacker had posed as the director of the schools and had requested W2 tax data on all employees. W2 form data were then emailed to the attacker by an employee.
A similar email phishing scam was reported to have been used to attack 8 school districts in Missouri, according to a report by the Missouri Department of Elementary and Secondary Education. In this case, only one of the eight school districts responded to the scam: An employee from the Odessa School District was fooled and send the tax details of the district’s employees to the attackers.
It is not only schools that are being targeted. A hospital in Campbell County, Wyoming was attacked this week. According to a Campbell County Health news release, a hospital executive was impersonated in this attack. A 66-year old hospital worker fell for the scam and emailed W-2 information about employees as requested.
Preventing successful W2 phishing scams requires a combination of technological solutions, employee training, and updates to policies and procedures. All employees with access to sensitive data must be advised of the risk and told to exercise caution. Policies should be introduced that require all email requests for employees’ tax information to be authenticated via telephone or other means. Organizations should also implement a robust spam filtering solution to prevent the scam emails from being delivered to employees’ inboxes.
However, if nothing is done to mitigate risk, 2017 is likely to be another record breaking year for the scammers.
You have no doubt heard of Locky and Cryptolocker, but what about Satan ransomware? Unfortunately, you may soon be introduced to this new ransomware variant. No matter where your organization is based, if you do not have a host of cybersecurity defenses to block ransomware attacks, this nasty file-encryptor may be installed on your network.
Satan Ransomware is being offered to any would-be hacker or cybercriminal free of charge via an affiliate model known as ransomware-as-a-service or RaaS. The idea behind RaaS is simple. Developers of ransomware can infect more computers and networks if they get an army of helpers to distribute their malicious software. Anyone willing to commit a little time to distributing the ransomware will receive a cut of any profits.
Ransomware authors commonly charge a nominal fee for individuals to participate in these RaaS schemes, in addition to taking a percentage of any ransomware payments that are generated. In the case of Satan ransomware, the developers offer RaaS totally free of charge. Anyone who wants to distribute the malicious software is free to do so. In exchange for their efforts they get to keep 70% of the ransom payments they generate. The remaining 30% goes to the ransomware authors. The gang behind the RaaS also offers higher percentages as infections increase as a reward for effort. All that is required to get started is to create a username and password. Access to the ransomware kit can then be gained.
What is alarming is how easy it is to participate in this RaaS scheme and custom-craft the malware. The gang behind the campaign has developed an affiliate console that allows the malware to be tweaked. The ransom amount can be easily set, as can the time frame for making payments and how much the ransom will increase if the payment deadline is exceeded.
Help is also offered with the distribution of the malware. Assistance is provided to make droppers that install the malware on victims’ systems. Help is offered to create malicious Word macros and CHM installers that can be used in spam email campaigns. Help is also offered to encrypt the ransomware to avoid detection. Even multi-language support is provided. Any would-be attacker can craft ransom demands in multiple languages via the RaaS affiliate console.
Satan ransomware performs a check to determine if it is running on a virtual machine. If it is, the ransomware will terminate. If not, it will run and will search for over 350 different file types. Those files will be locked with powerful encryption. File extensions are changed to. stn and the file names are scrambled to make it harder for victims to identify individual files. The ransomware will also wipe all free space on the hard drive before the ransom demand is dropped onto the desktop.
There is no decryptor for Satan ransomware. Recovery without paying the ransom will depend on organizations being able to restore files from backups. Since the ransomware also encrypts backup files, those backups will have to be in the cloud or on isolated devices.
RaaS is nothing new, but what is so worrying about Satan ransomware is how easy it has been made for affiliates. Next to no skill is required to run a ransomware campaign and that is likely to see many individuals take part in the RaaS program.
A spate of Gmail phishing attacks has hit the headlines this week. While the phishing scam is not new – it was first identified around a year ago – cybercriminals have adopted the campaign once more. The phishing emails are used to obtain Gmail login credentials are highly convincing,. A number of different tactics are used to evade detection, some of which are likely to fool even the most security aware individuals.
The Gmail phishing attacks start with an email sent to a Gmail account. Security aware individuals would be wary about an email sent from an unknown source. However, these attacks involve emails sent from a contact in the target’s address book. The email addresses are not masked to make them look like they have come from a contact. The email is actually sent from a contact’s account that has already been compromised.
Email recipients are far more likely to open emails sent from their contacts. Many people do not perform any further checks if the sender is known to them. They assume that emails are genuine solely from the source.
However, that is not the only technique used to fool targets. The attackers also use information that has been taken from the contact’s sent and received messages and add this to the email. An screenshot of an attachment or image that has already been included in a previous email between the contact and the target is included in the message. Even if the target is slightly suspicious about receiving an email, these additional touches should allay concern.
The aim of the email is to get the target to click on the image screenshot. Doing so will direct them to a Gmail login page where the target is required to sign in again. While this is perhaps odd, the page that the user is directed to looks exactly as it should. The page exactly mirrors what the user would normally expect.
Checking the website address bar should reveal that the site is not genuine; however, in this case it does not. The address bar shows the site is secure – HTTPS – and the web address includes accounts.google.com. The only sign of the scam is the inclusion of ‘data.text/html’ before accounts.google.com in the address bar.
Entering in account credentials will send that information directly to the attackers. The response is lightning quick. Account credentials are immediately used to log into the victim’s account. Before the victim even suspects they have been scammed, the entire contents of their Gmail account could be stolen, including sent and received emails and the address book. Contacts will be subjected to these Gmail phishing attacks in the same fashion.
Google is aware of the scam and is currently developing mitigations to prevent these types of attacks from occurring. In the meantime, however, users of Gmail should be particularly wary. Many users just glance at the address bar and look for the HTTPS and the web address. Failure to very carefully check the address bar and protocol before entering login credentials can – and certainly will in this case – result in the user’s account being compromised. Gmail accounts contain a huge amount of personal information. Information that could be used in future spear phishing attacks, extortion attempts, and other scams on the target and their contacts.
Research conducted by the anti-phishing training company PhishMe has shown a worrying increase in phishing attacks in 2016 and has highlighted the importance of taking steps to reduce the risk of spear phishing attacks.
Unfortunately, cybercriminals are becoming much more adept at crafting highly convincing spear phishing campaigns. A wide range of social engineering techniques are used to fool employees into responding to the emails and the campaigns are becoming much harder to identify.
Unfortunately responding to these emails can result in email and network credentials being compromised, malware and ransomware being installed on corporate networks, and sensitive data being emailed to the attackers.
The study of phishing attacks in 2016 showed attacks increased by 55% year on year. PhishMe research shows that out of the successful data breaches in 2016, 90% started with a spear phishing email.
In 2016, business email compromise attacks rose by an incredible 1300%, while ransomware attacks increased 400%. Cybercriminals are attacking companies with a vigor never before seen and unfortunately many of those attacks have been successful.
The figures from the U.S. Department of Health and Human Services’ Office for Civil Rights – which tracks U.S. healthcare data breaches – show that 2016 was the worst ever year on record for healthcare data breaches. At least 323 breaches of more than 500 records occurred in 2016. Undoubtedly many more breaches have yet to be discovered.
Cybercriminals and hackers have employees firmly in their crosshairs. Unfortunately, employees are easy targets. A recent survey conducted by cybersecurity firm Avecto showed that 65% of employees are now wary about clicking on links emailed to them by strangers. Alarmingly, that means 35% are not.
The same survey showed that 68% of respondents have no concerns about clicking on links sent by their friends and colleagues. Given the extent to which email addresses and passwords have been compromised in the last year, this is incredibly worrying. 1 billion Yahoo accounts were breached and 117 million email addresses were compromised as a result of the LinkedIn breach. Gaining access to email accounts is not a problem for cybercriminals. If those accounts are used to send spear-phishing emails, the chance of links being clicked are very high. Unfortunately, all it takes is for one email account to be compromised for access to a network to be gained.
The risk of spear phishing attacks was clearly demonstrated in 2015 when the largest ever healthcare data breach was discovered. 78.8-million health plan members’ records were stolen from Anthem Inc. That breach occurred as a result of an employee of one of the insurer’s subsidiaries responding to a spear phishing email.
Anthem Inc., is the second largest health insurer in the United States and the company spends many tens of millions of highly complex cybersecurity defenses. Those multi-million dollar defenses were undone with a single email.
Organizations must take steps to reduce the risk of speak phishing attacks. Unfortunately, there is no single solution to eradicate risk. A multi-layered defense strategy is required.
An advanced anti-spam solution is essential to prevent the vast majority of spam and phishing emails from being delivered to end users. SpamTitan for example, blocks 99.97% of spam email and 100% of known malware.
Employees must be trained and their training must be tested with phishing exercises. Practice really does make perfect when it comes to identifying email scams. Endpoint defenses should also be employed, along with anti-virus and antimalware software.
The risk of spear phishing attacks will increase again in 2017. Doing nothing to improve cybersecurity defenses and combat the spear phishing risk could prove to be a very costly mistake.
Last month, L.a. County reported one of the largest phishing attacks in the United States. A single phishing campaign directed at Los Angeles County employees saw an incredible 108 individuals fall for the scam. Each employee that responded to the campaign inadvertently divulged their email credentials to the attacker. 108 email accounts were compromised as a result of the one phishing campaign.
While it is not known whether the individual behind the campaign successfully retrieved any data from L.A County email accounts, the compromised email accounts were a treasure trove of sensitive information. The email accounts contained the sensitive information of more than 750,000 individuals.
While the announcement of the phishing attack was only made in December, the actual incident occurred on May 13, 2016. In contrast to the phishing and spam email campaigns of old that contained numerous spelling mistakes, grammatical errors, and bordered on the unbelievable, this campaign was expertly crafted. The attacker used realistic text and images, hence the reason why such a large number of employees fell for the scam.
Fortunately for L.A. County, the phishing attack was identified promptly – within 24 hours – therefore limiting the damage caused. A detailed forensic investigation revealed that 756,000 individuals had their sensitive information – including Social Security numbers and protected health information- exposed as a result of the attack.
There was further good news. The lengthy investigation confirmed the identity of the attacker, a Nigerian national – Austin Kelvin Onaghinor. A warrant has been issued for his arrest. Bringing that individual to justice may be another matter. Extraditing foreign nationals to the United States can be a difficult and long winded process. However, L.A District Attorney Jackie Lacey has vowed to “aggressively to bring this criminal hacker and others to Los Angeles County, where they will be prosecuted to the fullest extent of the law.”
Phishing attacks on this scale are unfortunately not that rare. Cybercriminals are becoming much better at crafting convincing emails and gaining access to corporate email accounts. All too often, the phishing attacks are not identified quickly, giving criminals plenty of time to exfiltrate data from compromised accounts. Many phishing campaigns are conducted to obtain network credentials and other information that can be used to gain a foothold in corporate networks. Once access is gained, all manner of nefarious activities take place.
This L.A. County phishing scam clearly demonstrates that employees are the weakest link in the security chain, which is why cybercriminals are committing more time and effort into phishing attacks. It is far easier to compromise an email account or gain access to a network if an employee provides their login credentials than attempting to find a chink in advanced cybersecurity defenses.
Protecting against phishing attacks requires an advanced spam filtering solution. Without such a solution in place, organizations have to rely on employees identifying emails as malicious. Something which is becoming much harder to do as cybercriminals perfect their social engineering techniques.
Blocking phishing emails and preventing them from being delivered to inboxes is the single-most effective solution to counter the phishing threat. Along with staff anti-phishing training and anti-phishing exercises, organizations can mount a defense against such attacks and avoid the not inconsiderable mitigation costs. Providing credit monitoring and identity theft protection services to 756,000 individuals is a sizeable cost for any organization to absorb.
2016 was a particularly bad year for data breaches. A large number of huge data breaches from years gone by were also discovered in 2016.
The largest breach of 2016 – by some distance – affected Yahoo. The credentials of more than 1 billion users were obtained by the gang behind the attack. A massive cyberattack on MySpace was discovered, with the attackers reportedly obtaining 427 million passwords. 171 million vk.com account details were stolen, including usernames, email addresses, and plaintext passwords. 2016 also saw the discovery of a massive cyberattack on the professional networking platform LinkedIn. The credentials of more than 117 million users were stolen in the attack. Then there was the 51-million iMesh account hack, and 43 million Last.fm accounts were stolen….to name but a few.
The data stolen in these attacks are now being sold on darknet marketplaces to cybercriminals and are being used to commit a multitude of fraud.
One of the biggest threats for businesses comes from business email compromise (BEC) scams. BEC scams involve an attacker impersonating a company executive or vendor and requesting payment of a missed invoice. The attacker sends an email to a member of the accounts team and requests payment of an invoice by wire transfer, usually for several thousand dollars. All too often, even larger transfers are made. Some companies have lost tens of millions of dollars to BEC fraudsters.
Since the email appears to have been sent from a trusted email account, transfer requests are often not questioned. Cybercriminals also spend a considerable amount of time researching their targets. If access to corporate email accounts is gained, the attackers are able to look at previous emails sent by the targets and copy their writing style.
They learn about how transfer requests are usually emailed, the terms used by each company and executive, how emails are addressed, and the amounts of the transfers that have been made. With this information an attacker can craft convincing emails that are unlikely to arouse suspicion.
The scale of the problem was highlighted earlier this year when the FBI released figures as part of a public awareness campaign in June. The FBI reported that $3.1 billion had been lost as a result of BEC scams. Just four months earlier, the losses were $2.3 billion, clearly showing that the threat was becoming more severe.
This year also saw a huge increase in W-2 scams in the United States. W-2 data is requested from HR departments in a similar manner to the BEC scams. Rather than trying to fool email recipients into making fraudulent transfers, the attackers request W-2 data on employees in order to allow them to file fraudulent tax returns in their names. The IRS issued a warning earlier this following a huge increase in W2 attacks on organizations in the United States.
Companies large and small were targeted, with major attacks conducted on Seagate, Snapchat, Central Concrete Supply Co. Inc, and Mainline Health. Between January and March 2016, 55 major – and successful – W-2 scams were reported to the IRS.
Attackers do not even need email account passwords to conduct these attacks. Email addresses of CEOs and executives can easily be spoofed to make them appear that they have been sent internally. The sheer number of stolen email addresses – and in many cases also passwords – makes the threat of BEC and W-2 attacks even greater. Security experts predict next year will be even tougher for businesses with even more cyberattacks than in 2016.
Improve Your Defenses Against Email-Borne Threats in 2017
Reducing the risk of these attacks requires multi-layered defenses. It is essential that all employees authorized to make corporate bank transfers receive training on email security and are alerted to the risk of BEC scams. Policies should be introduced that require bank transfer requests to be authorized by a supervisor and/or authenticated by phone prior to the transfer being made.
All employees should be instructed to use strong passwords and never to share work passwords anywhere else online. Many employees still use the same password for work as for personal accounts. However, if one online platform is breached, it can give the attackers access to all other platforms where the same password has been used – including corporate email accounts.
Organizations should also implement controls to block phishing and spear phishing attacks. Blocking phishing emails reduces reliance on the effectiveness of anti-phishing training for employees.
SpamTitan is a highly effective tool for blocking malicious spam emails, including phishing and spear phishing emails. SpamTitan uses a range of techniques to identify spam and scam emails including Bayesian analyses, greylisting and blacklists. SpamTitan incorporates robust anti-malware and anti-phishing protection, as well as outbound email scanning to block spam and scams from corporate email accounts. SpamTitan is regularly tested by independent experts and is shown to block 99.97% of spam email with a low false positive rate of just 0.03%.
2016 may have been a particularly bad year for data breaches and the outlook doesn’t look good for 2017, but by taking affirmative action and implementing better defenses against email-borne attacks, you could ensure that your company is not added to the 2017 list of data breach and scam statistics.
The email marketing service MailChimp employs security controls to ensure that its customers do not use the service to send spam; yet, this week malicious spam emails were sent from multiple accounts after a MailChimp account hack.
Customer accounts that were breached included Business News Australia, Brisbane’s The Sit Down Comedy Club, and gardening and home services provider Jim’ Group.
MailChimp accounts are valuable to spammers as subscribers to company newsletters are more likely to trust the emails than they would an email from an unknown sender. The hijacked accounts were used to send spam emails demanding an invoice be paid. Spammers often target businesses with malicious emails that spread malware. If malware such as a keylogger can be installed, the attackers can gain access to corporate email accounts or gain network access. Corporate bank account details can be stolen and fraudulent transfers made.
A fake invoice is a common ploy used to fool email recipients into opening an infected email attachment or clicking on a malicious link. A sense of urgency is often included to scare the recipient into opening the attachment. A threat of legal action if the outstanding invoice is not paid promptly is a common tactic.
In this case, a number of different variants were sent. Some emails contained an image with an embedded hyperlink which recipients could click to view the invoice. The spammers also included the logo of accounting software Quickbooks for extra authenticity.
Initially, it appeared that MailChimp had experienced a security breach that resulted in spammers gaining access to accounts; although the company issued a statement saying that an investigation of the incident did not point to an internal breach.
MailChimp told Motherboard “MailChimp’s normal compliance processes identified and disabled a small number of individual accounts sending fake invoices. We have investigated the situation and have found no evidence that MailChimp has been breached. The affected accounts have been disabled, and fraudulent activity has stopped.”
How the MailChimp account hack was pulled off remains a mystery. The spammers may have managed to guess the passwords that were used to secure accounts or they could have obtained those passwords by other means. The practice of reusing passwords on multiple platforms could be to blame. If a breach of one platform occurs, cybercriminals can gain access to all other online services that use the same password.
In a recent post, computer security blogger Graham Cluley suggested some passwords were obtained by the password stealing Trojan Vawtrak. Cluley was contacted by an anonymous source who claimed to be in possession of two thousand MailChimp login credentials which were recorded by Vawtrak.
Details of the MailChimp account hack are unlikely to be released, although the incident shows how important it is for businesses to use two-factor authentication to secure their online accounts. The incident also shows how important it is to exercise caution and to treat any email attachment of hyperlink as potentially malicious, even if the sender of the email is known.
The biggest hacking threat to businesses comes not from unpatched software, but phishing. An incredibly simple, yet highly effective way that cybercriminals gain access to networks. Phishing can be used to bypass even the most sophisticated of cybersecurity defenses. Why go to the trouble of trying to find a weakness in highly sophisticated cybersecurity defenses when a simple email can get an employee to give the attacker their login credentials?
As Jeh Johnson, Secretary for the U.S. Department of Homeland Security, recently explained to attendees at the Financial Crimes and Cybersecurity Symposium in New York, phishing is one of the department’s biggest fears.
“The most devastating attacks by the most sophisticated attackers almost always begin with the simple act of spear-phishing,” says Johnson. It is no surprise that phishing is the biggest hacking threat to businesses. Phishing is alarmingly effective.
Even multi-million dollar cybersecurity defenses can be bypassed with a simple phishing email. The social engineering techniques used by cybercriminals often get the desired response.
Most of the largest hacks in the United States were possible not due to a security weakness, but because an employee responded to a phishing email. The cyberattacks on Ebay, Target, the Office of Personnel Management, JP Morgan, Anthem, and Sony Pictures all started with a simple phishing email.
Cybercriminals have also started using phishing emails to distribute ransomware. Malicious links are sent to company employees along with a request to click for free items, to take part in prize draws, or even to secure their computers to prevent cyberattacks.
Phishing has been around for as long as email and cybercriminals will not stop using phishing to gain access to networks, install malware, lock files with ransomware, and steal data. Phishing is likely to remain the biggest hacking threat to businesses. Organizations – and their employees – just need to get better at identifying and blocking phishing attempts.
One of the best defenses against phishing is to ensure that all staff members from the CEO down receive security awareness and anti-phishing training.
Training alone is insufficient. Staff can be told how to identify phishing attempts, but their ability to spot a phishing email must be put to the test. Anti-phishing skills need to be regularly tested. Dummy phishing emails should be sent to check to see who responds. Johnson says his department often sends fake phishing emails – free Redskins tickets for example – to test anti-phishing prowess. Anyone who responds is provided with further training.
Training is important in case a phishing email reaches an employee’s inbox, although it is far better to ensure phishing emails are not delivered. The best technological defense against phishing is the use of a spam filter. If phishing emails are not delivered to inboxes, staff members will not be able to respond and their anti-phishing skills will not be put to the test.
SpamTitan is a highly effective spam filtering solution for businesses that blocks 99.97% of spam email. Each month SpamTitan is independently tested for effectiveness. SpamTitan has now won 36 consecutive VB Bulletin antispam awards.

Malicious email spam volume has increased again. According to the latest figures from Kaspersky Lab, malicious email spam volume in Q3, 2016 reached a two-year high.
In Q3 alone, Kaspersky Lab’s antivirus products identified 73,066,751 malicious email attachments which represents a 37% increase from the previous quarter. Malicious spam email volume has not been at the level seen in Q3 since the start of 2014. Kaspersky Lab’s figures show that six out of ten emails (59.19%) are spam; a rise of around 2% from Q2, 2016. September was the worst month of the year to date, with 61.25% of emails classified as unsolicited spam.
Spam includes a wide range of unsolicited emails including advertising and marketing by genuine companies, although cybercriminals extensively use email to distribute malware such as banking Trojans, keyloggers, and ransomware. The use of the latter has increased considerably throughout the year. In Q3, the majority of malicious emails contained either ransomware or downloaders that are used to install ransomware on personal computers and business networks.
Ransomware is a form of malware that locks files on a computer with powerful encryption, preventing the victim from gaining access to their data. Many ransomware variants are capable of spreading laterally and can encrypt files on other networked computers. All it takes is for one individual in a company to open an infected email attachment or click on a malicious link in an email for ransomware to be downloaded.
Spammers often use major news stories to trick people into opening the messages. The release of the iPhone 7 in Q3 saw spammers take advantage. Spam campaigns attempted to convince people that they had won an iPhone 7. Others offered the latest iPhone at rock bottom prices or offered an iPhone 7 for free in exchange for agreeing to test the device. Regardless of the scam, the purpose of the emails is the same. To infect computers with malware.
There was an increase in malicious email spam volume from India in Q3. India is now the largest source of spam, accounting for 14.02% of spam email volume. Vietnam was second with 11.01%, with the United States in third place, accounting for 8.88% of spam emails sent in the quarter.
Phishing emails also increased considerably in Q3, 2016. Kaspersky Lab identified 37,515,531 phishing emails in the quarter; a 15% increase compared to the Q2.
Business email compromise (BEC) attacks and CEO fraud are on the rise. These scams involve impersonating a CEO or executive and convincing workers in the accounts department to make fraudulent bank transfers or email sensitive data such as employee tax information. Some employees have been fooled into revealing login credentials for corporate bank accounts. Cybercriminals use a range of social engineering techniques to fool end users into opening emails and revealing sensitive information to attackers.
Security awareness training is important to ensure all individuals – from the CEO down – are aware of email-borne threats; although all it takes is for one individual to be fooled by a malicious email for a network to be infected or a fraudulent bank transfer to be made.
The rise in malicious email spam volume in Q3, 2016 shows just how important it is to install an effective spam filter such as SpamTitan.
SpamTitan has been independently tested by VB Bulletin and shown to block 99.97% of spam emails. SpamTitan has also been verified as having a low false positive rate of just 0.03%. Dual antivirus engines (Kaspersky Lab and ClamAV) make SpamTitan highly effective at identifying malicious emails and preventing them from being delivered to end users.
If your end users are still receiving spam emails you should consider switching antispam providers. To find out the difference that SpamTitan can make, contact the Sales Team today and register for a free, no obligation 30-day trial.
Thanksgiving weekend sees Americans head on line in the tens of millions to start online Christmas shopping in earnest and this year the holiday season scams have already started.
Black Friday and Cyber Monday are the busiest online shopping days, but some retailers are kickstarting their promotions early this year and have already started offering Black Friday deals. Amazon.com for example launches its first Black Friday offers tomorrow, well ahead of the big day on 25th November.
It is no surprise that retailers are trying to get ahead. 41% of shoppers start their holiday shopping in October according to a recent National Retail Federation survey. 41% of shoppers wait until November. 82% of shoppers like to make an early start, and this year so are the scammers.
A popular tactic used by cybercriminals is typosquatting – the registration of fake domains that closely match the brand names of well-known websites. Phishers use this tactic to obtain login credentials and credit card numbers. In recent weeks, there has been an increase in typosquatting activity targeting banks and retailers.
A fake domain is registered that closely matches that of the targeted website. For instance, the Amaz0n.com domain could be purchased, with the ‘o’ replaced with a zero. Alternatively, two letters could be transposed to catch out careless typists. A website is then created on that domain that closely matches the targeted website. Branding is copied and the layout of the genuine site is replicated.
There is another way that scammers can take advantage of careless typists. Each country has its own unique top level domain. Websites in the United States have .com. Whereas, websites registered in the Middle Eastern country of Oman have the .om domain. Scammers have been buying up the .om domains and using them to catch out careless typists. In the rush to get a holiday season bargain, many users may not notice they have typed zappos.om instead of zappos.com.
Visitors to these scam websites enter their login credentials as normal, yet all they are doing is giving them to the attackers. The scammers don’t even need to spoof an entire website. When the login fails, the site can simply redirect the user to the genuine site. Users then login as normal and complete their purchases. However, the scammers will have their login credentials and will be able to do the same.
However, many websites now have additional security features to prevent the use of stolen login credentials. If a login attempt is made from an unrecognized IP address, this may trigger additional security features. The user may have to answer a security question for example.
Some scammers have got around this problem. When a user attempts to login on a scam site, a login session is automatically opened on the genuine website. The information entered on the scam site is then used by the attackers on the genuine site. When the unusual IP address triggers an additional security element, this is then mirrored on the scam site with the same question forwarded to the user. The question is answered, and an error message is generated saying the login was unsuccessful. The user is then redirected to the genuine site and repeats the process and gains access. Chances are they will be unaware their account details have been compromised. Hours later, the scammers will login to the genuine site using the same credentials.
Businesses must also exercise caution at this time of year and should take steps to reduce the risk of employees falling for holiday season scams. Employees keen to get the latest bargains will undoubtedly complete some of their purchases at work.
Email scams increase at this time of year and business email accounts can be flooded with scam emails. Offers of discounts and special deals are likely to flood inboxes again this year. Email holiday season scams may not be about stealing login credentials. Given the increase in malware and ransomware infections in 2016, this holiday season is likely to see many holiday season scams infect businesses this year. A careless employee looking for an online bargain could all too easily click a link that results in a malware download or ransomware infection.
As holiday season fast approaches, the scammers will be out in force. It is therefore important for both businesses and consumers to take extra care. If you want to find out how you can protect your business from malware and ransomware, contact the TitanHQ team today and find out more about our security solutions.
