Los Angeles Valley College Ransomware Attack Highlights Importance of Solid Ransomware Defenses

A Los Angeles Valley College ransomware attack has resulted in file systems being taken out of action for seven days and considerable costs being incurred to resolve the infection.

Attackers succeeded in taking control of one of the college’s servers on December 30, 2016. When staff returned after the Christmas break they discovered the computer system to be out of action and essential files locked with powerful encryption.

The attackers had succeeded in locking a wide range of file types on network drives and computers. Unfortunately, the college was unable to recover the files from a backup. Administrators therefore faced a tough decision. To try to recover from the attack without paying the ransom and risk file loss or to give in to the attacker’s demands and pay for the keys to unlock the encryption.

Los Angeles Valley College Ransomware Attack Nets Criminal Gang $28,000

Due to the extent of the infection and the number of devices affected, the ransom payment was considerable. The attackers set the price at $28,000 for the decryption keys. The ransom demand was high but the college had little in the way of options.

The ransom note that was loaded onto the college’s X-drive said if the ransom was not paid within 7 days, the unique keys to unlock the encryption would be permanently deleted. That would likely have resulted in all of the locked files being permanently lost.

The college enlisted help from cybersecurity experts to determine the likelihood of files being recovered without paying the ransom. However, college administrators were advised to dig deep and pay the attackers for the key. While there is no guarantee that paying the ransom would result in viable keys being supplied, the college’s cybersecurity experts said there was a high probability of data recovery if the ransom was paid and a very low probability of data being recovered if the ransom demand was ignored. The likely cost of resolving the infection without paying the ransom was also estimated to be higher than attempting to remove the infection. The decision was therefore made to pay the attackers in Bitcoin as requested.

The attackers made good on their promise and supplied the keys to unlock the data. Now IT staff must apply those keys and remove the encryption on the server, network drives, and the many infected computers. Fortunately for the college, a cyber insurance policy will pay out and cover the cost of the ransom and resetting systems. However, there will be other costs that need to be covered, which will must be paid by the district.

Recovery from the Los Angeles Valley College ransomware attack will not be a quick and simple process, even though the decryption keys have been supplied by the attackers. The district’s Chief Information Officer Jorge Mata said “There are often a lot of steps where there’s no coming back, and if you pick the wrong path, there’s no return.” The recovery process therefore requires care and precision and cannot be rushed. The process could well take a number of weeks. The main priority is to recover the email system. Other systems and devices will then be methodically restored.

Los Angeles Valley College Ransomware Attack One of Many Such Attacks on Educational Institutions

The Los Angeles Valley College ransomware attack has hit the headlines due to the extent of the infection and high ransom demand, but it is one of many such attacks to have occurred over the past 12 months. Educational institutions have been heavily targeted by attackers due to the value of college and school data. Educational establishments cannot risk data loss and are therefore likely to pay the ransom to regain access to files.

In the past few months, other educational institutions in the United States that have been attacked with ransomware include M.I.T, University of California-Berkeley, and Harvard University as well as many K-12 schools throughout the country. Figures from Malwarebytes suggest that 9% of ransomware attacks targeted educational establishments.

How Can Educational Institutions Protect Against Ransomware Attacks?

There are a number of steps that educational institutions can take to reduce the risk of ransomware attacks and ensure that recovery is possible without having to resort to paying a ransom. The most important step to take is to ensure that all data is backed up regularly, including the email system. Backups should be stored on air-gapped devices, not on network drives. A separate backup should be stored in the cloud.

However, backups can fail and files can be corrupted. It is therefore important that protections are implemented to prevent ransomware from being delivered via the two most common attack vectors: Email and the Internet.

Email is commonly used to deliver ransomware or malicious code that downloads the file-encrypting software. Preventing these malicious emails from being delivered to staff and students’ inboxes is therefore essential. An advanced spam filter such as SpamTitan should therefore be installed. SpamTitan blocks 99.97% of spam emails and 100% of known malware.

To protect against web-borne attacks and prevent exploit kit activity and drive-by downloads, schools and colleges should use a web filter such as WebTitan. WebTitan uses a variety of methods to block access to malicious webpages where malware and ransomware is downloaded. WebTitan can also be configured to prevent malicious third-party adverts from being displayed. These adverts – called malvertising – are commonly used to infect end users by redirecting their browsers to websites containing exploit kits.

Risk of Spear Phishing Attacks Must Not be Ignored

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.

How Do Spam Filters Block Spam Email?

How do spam filters block spam email? Spammers are constantly adapting their strategies to bypass spam filters and deliver more malicious messages to corporate users’ inboxes, so how do antispam solutions keep pace and block these annoying and often malicious messages?

Many anti-spam solutions rely on blacklists to identify spammers’ email addresses and IP addresses. Once a spammer’s IP address has been identified, it is added to a global spam blacklist.

Antispam solutions check incoming messages against these blacklists. As soon as an IP address is blacklisted, any email sent from that IP address is automatically marked as spam and will be deleted or quarantined.

Spammers are aware that the lifespan of an email address for spamming is short. As anti-spam solutions have improved, the time delay between an email address being used for spamming and it being added to a global spam blacklist has reduced considerably. Whereas spammers used to be able to use an email address for weeks before it was identified by anti-spam solutions and blacklisted, now the lag has been reduced to days or even hours.

Spammers therefore have a very small window of opportunity to use email addresses and mail servers for spamming before they are detected and blacklisted.

Snowshoe and Hailstorm Spam Tactics to Get Messages to Inboxes

Spammers have attempted to increase the timespan for using email addresses using a number of methods, the most common being conducting snowshoe campaigns. This tactic involves sending out very low numbers of spam email messages from each IP address. If spam email volume is kept low, there is less chance of the IP address being recognized as used for spamming. To ensure sufficient numbers of messages are sent, spammers use millions of IP addresses. Even using this tactic will not allow the spammers to conduct their activities undetected for very long. Spammers therefore need to constantly add new IP addresses to their spamming networks to enable them to continue conducting their campaigns.

Snowshoe tactics are now widely used and the technique is highly effective, although a new tactic has recently been uncovered that is referred to as hailstorm spamming. Hailstorm spam campaigns similarly involve extremely large numbers of IP addresses, yet they are used very briefly and intensely. Rather than trying to stay under the radar, the spammers use those IP addresses to send huge volumes of messages very quickly.

Researchers at Cisco Talos recently analyzed both tactics and determined that the DNS query volume from a typical snowshoe campaign involved around 35 queries an hour. A hailstorm spam campaign involved around 75,000 queries an hour. The snowshoe campaign would continue at that rate for many hours, whereas the hailstorm spam campaign spiked and then fell to next to nothing. Hailstorm campaigns can therefore be used to deliver huge volumes of emails before the IP addresses are added to blacklists.

How do Spam Filters Block Spam Email?

How do spam filters block spam email when these tactics are used? Snowshoe and hailstorm spam campaigns are effective against antispam solutions that rely on blacklists to identify spammers. Only when an IP address is added to a blacklist will the spam email messages be blocked.  Advanced spam solutions offer far greater protection. Blacklist are still used, although a number of other methods of spam detection are employed.

Conducting a Bayesian analysis on all incoming spam email messages greatly reduces the volume of spam email messages that are delivered to end users. A Bayesian analysis involves reading the contents of a message and assessing the words, phrases, headers, message paths, and CSS or HTML contained in the message. While scoring, messages based on content can be effective, Bayesian spam filters also learn as they go. They constantly compare spam emails to legitimate emails and build up the range of spam characteristics that are checked. As spammers change tactics, this is picked up by a Bayesian spam filter and spam messages continue to be filtered.

The use of greylisting is also important in a spam filter. There will be some messages that pass all of the checks and some that monumentally fail. Categorizing these messages as genuine or spam is therefore simple. However, there is a sizeable grey area – messages that could potentially be spam.

If all of these messages are blocked, many genuine emails would not be delivered. If they are all allowed, many spam messages would get through. This would result in poor catch rates or extremely high false positive rates. Greylisting helps in this regard. Suspect messages are returned to the sender’s mail server and a request is made for the message to be resent. Since spammers mail servers are typically constantly busy, these requests are either ignored or they are not dealt with promptly. The time it takes for the message to be resent is therefore a good indicator of whether the message is genuine.

SpamTitan – Keep Your Inboxes Spam Free

SpamTitan uses a range of methods to identify spam emails including blacklists, Bayesian analyses, and greylisting. These checks ensure that more spam emails are identified and blocked, even if IP addresses have yet to be added to spam blacklists. This makes SpamTitan highly effective, even when spammers use snowshoe and hailstorm spamming tactics. By using a range of methods to identify spam emails, spam detection rates are improved and false positives are reduced.

SpamTitan is independently tested every month to determine its effectiveness. SpamTItan is consistently verified as capable of blocking more than 99.97% of spam emails, with a false positive rate below 0.03%.

Why Should Businesses Perform Outbound Email Scanning?

All antispam solutions and spam filters check inbound messages for common spam signatures; however, it is also important to choose a solution that performs outbound email scanning. Outbound email scanning ensures spam emails, or emails containing malware, are not sent from an organization’s email accounts or domains.

Your employees would be unlikely to knowingly use their corporate email accounts to send spam emails, but malware infections can allow cybercriminals to gain access to email accounts and use them to send high volumes of spam email messages. Cybercriminals could also compromise email accounts and use an organization’s domain to send malware and ransomware to clients and customers.

Should this happen, it can have a seriously detrimental effect on an organization’s reputation and may result in corporate email accounts or an entire domain being blacklisted.

Blacklists are maintained by a number of organizations – spamhaus.org for example. Internet Service Providers (ISPs), web servers, and antispam solutions check these blacklists before allowing emails to be delivered to end users. If a particular IP address, email account, or domain is listed in one of the blacklist databases, emails sent from the domain, IP address or email account will not be delivered.

Blacklists are updated in real-time and contain many millions of blocked domains and email addresses that have been reported as having been used for unwanted activity such as the sending of spam emails. If emails are sent from a blacklisted account, domain, or IP address those emails will either be directed to a quarantine folder, deleted, or will simply be rejected.

If a business has its domain added to a spam blacklist important emails to clients and customers will not get through. This can prove costly, as real estate firm Keller Williams has recently discovered.

Blacklisted Domains and Email Accounts Can Prove Costly for Businesses

Over the past few days, email messages sent from the kw.com domain used by Keller Williams have been rejected by AOL. Yahoo has been blocking emails from the kw.com account for some time. The problem appears to be the addition of the kw.com domain to spam blacklists.

If a Keller Williams real estate agent needs to send an email to a customer who has an AOL or Yahoo account, it will not be delivered. Agents have therefore been forced to get customers to open Google email accounts in order to send online paperwork or documents requiring e-signatures.

The issue also affects online paperwork sent via the transaction management software program Ziplogix, with one Keller Williams agent also claiming Dotloop is also affected. Some agents at Keller Williams have reportedly had to send important paperwork for listings and sales via personal email accounts to ensure emails are delivered.

The AOL website explains that when domains have been flagged as being abusive, the server will be temporarily blocked until the spamming stops. Until a domain is removed from its blacklist, AOL account holders will be prevented from receiving emails from the blocked domain. Removing the domain from the blacklist can take up to a week.

Removing a domain from the 80+ commonly used spam blacklists can be a time-consuming task; furthermore, if spam emails are sent from the account again, the domain will simply be added to the blacklists once more.

Outbound Email Scanning Prevents the Blacklisting of an Organization’s Domain

Unlike many third-party antispam solutions, SpamTitan checks incoming email messages for spam signatures as well as performing outbound email scanning. If an email account has been compromised and is being used to send spam emails, if malware is sending spam, those messages will be blocked and will not be sent. Outbound email scanning is an important protection that will prevent an organization’s domain or email accounts from being used to send spam or malware.

Organizations can therefore avoid the embarrassment and reputation damage that results from being suspected as engaging in spamming or malware delivery. They can also rest assured that in addition to blocking 99.97% of inbound email spam, their domains and email accounts will not be added to spam blacklists.

Malicious Spam Email Volume Increases Again

Spam email volume has reduced over the past couple of years following the takedown of key botnets – and individuals – behind some of the biggest spamming campaigns. It was starting to look like the super-spamming days of the early 2010s were a thing of the past. However, spam email volume has been increasing in recent months.

Necurs botnet activity has increased and last month the Tofsee botnet came back to life after years of dormancy. Both of these botnets had previously been used to send annoying but relatively harmless spam emails offering cheap pharmaceuticals and offers of beautiful Russian brides. However, the increase in activity is also coupled with the move to malicious email attachments containing malware and ransomware.

These and other botnets such as Helihos are also growing in size at alarming rates and spam email volume is soaring. Some reports suggest spam email volume has increased from around 200,000 spam emails per second to 450,000 emails per second over the past couple of months.

But what are these malicious email attachments, and how big is the risk?

97% of Malicious Spam Email Attachments Contain Locky Ransomware

Locky ransomware first appeared in February 2016. It has since become one of the biggest email threats. The ransomware is being sent in massive spam campaigns and increasingly sophisticated social engineering techniques are used to infect end users.

To put these email campaigns into some perspective, historically, the volume of spam email used to deliver malware, ransomware, and other email nasties stood at around 2% of the total spam email volume. By around April this year, two months after Locky first appeared on the scene, malicious spam emails containing the ransomware accounted for around 18% of total spam email volume.

The Quarterly Threat Report issued by ProofPoint earlier this month suggests the volume of spam email containing malicious attachments or links reached record levels in quarter 3, 2016. The vast majority of those emails contained Locky. According to the report, 97% of captured spam emails with malicious attachments were used to deliver Locky. That’s a 28% increase from Q2, and a 64% increase since Q1.

Since its release, Locky ransomware has been infecting users via Word documents containing malicious macros, JavaScript files, executable HTML files (HTA), and more recently Windows Script Files (WSF) hiding the Nemucod downloader. Now, another change has been detected. Earlier this month, researchers at the Microsoft Malware Protection Center discovered the actors behind Locky ransomware had made another change to the way they infect computers and made the switch to shortcut files (LNK) containing PowerShell commands.

This discovery coincided with a drop in detection and a relatively quiet period for the past two weeks. However, Locky is back with a vengeance. On Monday this week, three new campaigns were detected, one of which was massive and involved 14 million messages in around half a day. 6 million of those messages were sent in a single hour!

The risk from Locky is considerable. Locky is capable of deleting Windows Shadow Files and encrypting a wide range of data, including data on portable storage devices and network drives. Resolving an attack can prove extremely costly. It is therefore essential to improve defenses to prevent attacks.

Ransomware and Malware Protection

Larger botnets and the move to malicious messages means organizations need to be prepared and take steps to ensure that these messages are effectively blocked.

Protecting your organization from email attacks is critical. It is therefore essential to employ a robust enterprise spam filtering solution. SpamTitan blocks 99.7% of spam email, preventing malicious email attachments and links from being delivered to your end users. This reduces reliance on training programs to educate end users on email threats.

Preventing ransomware infections requires a multi-layered approach. There is no silver bullet that will offer total protection against ransomware infections, but there are security products that can greatly reduce risk.

Protecting against exploit kits and malvertising requires a web filtering solution. By blocking websites known to contain malware or exploit kits, and carefully controlling the website content that can be accessed by employees, organizations can effectively protect against web-borne infections. WebTitan offers that protection and can be used to block malicious websites and reduce the risk from infections via malvertising.

Along with intrusion detection systems, firewalls, antivirus and anti-malware solutions, it is possible to defend against ransomware and malware attacks and keep your data secured.

Surge in Ransomware Emails In March 2016

A new report by anti-phishing training company PhishMe shows a marked rise in the volume of ransomware emails in March. The report shows that spam emails are now predominantly being used to deliver ransomware to unsuspecting victims. The spike in ransomware emails highlights how important it is to conduct anti-phishing training and to use anti-spam solutions to prevent the malicious file-encrypting software from being delivered to employee’s inboxes.

Spike in Ransomware Emails as Criminals Seek Easy Cash

Ransomware has been around for about a decade, yet it has not been favored by cybercriminals until recently. Throughout 2015, under 10% of phishing emails were being used to transmit ransomware. However, in December there was a major spike in ransomware emails, which accounted for 56% of all phishing emails in December. The upward trend has continued in 2016 and by March, 93% of phishing emails contained ransomware – or were used to infect users by directing them to malicious websites where drive-by downloads of the malicious software occurred.

Spam email volume has been in general decline, in no small part to the shutting down of major botnets in recent years. However, that does not mean that the threat of cyberattacks via email can be ignored. In fact, PhishMe’s figures show there has been a surge in the number of phishing emails being sent. In the first quarter of 2016, the number of detected phishing emails soared to 6.3 million, which represents a 789% increase from the volume captured in the last quarter of 2015.

Ransomware is increasingly being used by cybercriminals for a number of reasons. Ransomware is now easy to obtain and send out. Many ransomware authors offer ransomware-as-a-service to any criminal looking to make a quick buck. Not only can the ransomware be hired for next to nothing, instructions are supplied on how to use it and criminals are allowed to set their own ransoms and timescales for payment. All they need to do is pay a percentage of the ransoms they obtain to the authors.

What makes the use of ransomware even more attractive is the speed at which criminals can get paid. Time limits for paying ransoms are usually very short. Demands for payment within 48 hours are not uncommon. While phishing emails have commonly been used to obtain credit card details from victims, which then need to be sold on, criminals can run a ransomware campaign and rake in Bitcoin payments in just a few days.

The ransoms being demanded are also relatively low. This means that many individuals can afford to pay the ransom to obtain the decryption keys to unlock their files, and businesses are also likely to pay. The cost of recovering data and restoring systems, together with the lost revenue from the time that computer systems are down, is often less than the ransom being demanded.

Ransomware Is Becoming Much More Sophisticated

The latest forms of ransomware now being used – Locky, CryptXXX, TeslaCrypt, and Samas (Samsam) – are capable of spreading laterally. Not only can the ransomware infect files on a single computer, other networked computers can also be infected, as can network drives, servers, portable storage devices, and backup drives. Some forms are also capable of deleting Windows shadow copies and preventing the restoration of files from backups.

All that the criminals need is for one business computer to be infected in order to encrypt files throughout the network. That means only one end user needs to be fooled into opening an infected attachment or visiting a malicious webpage.

Ransomware emails often contain personal information to increase the likelihood of an individual clicking a malicious link or opening an infected attachment. Word files are now commonly being used to infect users. Embedded macros contain code that downloads the malicious payload.

The malicious software is sent out in spear phishing campaigns targeting one or two users in a company, such as accounts and billing department executives. Personal information is often used in the emails – names, addresses, and job titles for example – to increase the likelihood of attachments being opened and links being clicked.

As criminals get better at crafting phishing emails and the ransomware becomes more sophisticated, it is more important than ever to use anti-spam solutions such as SpamTitan to trap ransomware emails and prevent them from being delivered. SpamTitan traps 99.9% of spam emails, helping organizations protect their networks from ransomware attacks.

Beware of GozNym Banking Malware – A Silent Threat That Can Empty Bank Accounts

Eastern European hackers may only have had access to GozNym banking malware for a few days, but they have already used the malicious software to make fraudulent bank transfers from more than two dozen bank accounts. The new malware is primarily being used to target banks and credit unions, although the attackers have also used the malware to attack e-commerce platforms. 22 attacks have been conducted on financial institutions in the United States with a further 2 attacks in Canada. So far the attackers behind the GozNym banking malware have managed to steal at least $4 million from U.S and Canadian banks.

GozNym Banking Malware Combines Gozi ISFB with Nymaim Source Code

As the name suggests, GozNym banking malware was developed by combining two different malware strains – Nymaim and Gozi ISFB.

IBMs X-Force Research team believe the new malware is the work of the team behind Nymaim malware, as the source code of Nymaim is understood to be only held by the original developers of the malware. The source code for Gozi ISFB malware has previously been leaked on two occasions. X-Force analysts think the Nymaim malware developers obtained that source code and used the best parts to form the new hybrid Trojan.

Nymaim malware has previously been used almost exclusively as a method of ransomware delivery, although the group behind the malware started using it as a banking Trojan late last year. Nymaim malware is a two stage malware dropper that is loaded onto computers using an exploit kit.

Links to a website containing the Blackhole Exploit Kit are sent via spam email. Once Nymaim has been loaded onto a computer, the second payload is deployed. In the case of GozNym banking malware the second stage is the running of Gozi ISFB code.

GozNym banking malware is stealthy and persistent. The malware remains dormant on a computer until the user logs into their bank account. When account details are entered, GozNym records the login credentials and silently sends them to the attackers’ command and control server. If GozNym banking malware is installed, the user will be unaware that their banking sessions have been compromised.

IBM recommends using adaptive malware detection solutions to reduce the risk of an attack. Anti-spam solutions such as SpamTitan can prevent emails containing the malicious links from being delivered, while WebTItan web filtering solutions can be used to block websites containing malicious code and exploit kits.

With new malware constantly being developed – around 1,000,000 new malware samples are now being released every day according to Symantec – organizations now need to implement sophisticated multi-layered defenses to protect their networks from malware infections.

Healthcare Ransomware Attack Sees Hospital Pay $17K Ransom to Unlock EHR

Over the past 12 months, cybercriminals have used ransomware with increasing frequency to extort money out of businesses, leading some security experts to predict that healthcare ransomware infections would become a major problem in 2016.

Would cybercriminals stoop so low and attack the providers of critical medical care? The answer is yes. This week a U.S. hospital has taken the decision to pay a ransom to obtain the security keys necessary to unlock data that had been encrypted by ransomware. The attack does not appear to have been targeted, but the ransom still needed to be paid to unlock the hospital’s electronic medical record system.

Last year, Cryptowall infections were regularly reported that required individuals to pay a ransom of around $500 to get the security key to recover files. However, when businesses accidentally install ransomware the ransom demand is usually far higher. Cybercriminals can name their price and it is usually well in excess of $500.

Healthcare Ransomware Infection Results in Hospital Paying $16,664 to Unlock EHR

While businesses have been targeted by cybercriminal gangs and have had their critical data locked by ransomware, it is rare for healthcare providers to be attacked. The latest healthcare ransomware infection does not appear to have been targeted, instead a member of staff inadvertently installed malware which locked the hospital’s enterprise-wide electronic health record system (EHR): The system that houses patient health records and critical medical files.

The EHR of Southern California’s Hollywood Presbyterian Medical Center was locked on February 5, 2016., with physicians and other members of the hospital staff unable to access the EHR to view and log patient health information. An investigation into the IT issue was immediately launched and it soon became apparent that the database had been locked by ransomware.

No one wants to have to pay cybercriminals for security keys, and the hospital took steps to try to recover without having to give in to ransom demands. The Police and FBI were contacted and started an investigation. Computer experts were also brought in to help restore the computer system but all to no avail.

The news of the healthcare ransomware attack broke late last week, with early reports suggesting the hospital had received a ransom demand of 9,000 Bitcoin, or around $3.4 million. The EHR was taken out of action for more than a week while the hospital attempted to recover and unlock its files.

Eventually, the decision had to be taken to pay the ransom. While it may have been possible for patient health data to be restored from backups, the time it would take, the resources required to do that, and the disruption it would likely cause was not deemed to be worth it. Allen Stefanek, CEO of Hollywood Presbyterian Medical Center, took the decision to pay the ransom to obtain the security key to unlock the data.

In a statement posted on the company’s website he confirmed that the reports of a ransom demand of 9,000 Bitcoin were untrue. The attackers were asking for 40 Bitcoin, or $16,664, to release the security key to unlock the hospital’s data.

Stefanek said, “The quickest and most efficient way to restore our systems and administrative functions was to pay the ransom and obtain the decryption key. In the best interest of restoring normal operations, we did this.”

Fortunately, healthcare ransomware attacks are relatively rare, as many healthcare providers in the United States already have controls in place to reduce the likelihood of an attack being successful. Staff are trained to be vigilant and not to install software on healthcare devices or open suspicious email attachments. Many use a spam filter to quarantine suspect emails. The latter being an essential protection against healthcare ransomware attacks.

The Importance of a Robust Spam Filter to Prevent Healthcare Ransomware Attacks

A healthcare ransomware attack does not just have a financial impact; it has potential to cause actual harm to patients. The delivery of healthcare services is slowed as a result of the inability to access and share healthcare data, and not being able to view patient health records could delay the delivery of critical patient care or result in incorrect medications being prescribed. That could be a life or death matter. Preventing healthcare ransomware attacks is therefore essential. A technological solution should be employed for maximum protection.

TitanHQ’s SpamTitan software has been developed to keep businesses protected from malware and ransomware attacks. SpamTitan uses two anti-malware engines to maximize the probability of spam emails and malicious attachments being caught and prevented from being delivered to end user inboxes. SpamTitan catches 99.9% of Spam email and quarantines emails with suspicious attachments to prevent them from being delivered.

If you want to reduce the risk of a suffering a ransomware attack and having to pay cybercriminals to unlock critical data, using a robust, powerful anti-spam solution such as SpamTitan is the best way to protect computers and networks from attack. Along with staff training to improve understanding of healthcare ransomware and other malware, it is possible to prevent attacks from being successful.

McAfee SaaS Email Protection Products Dropped by Intel Security

Following the recent news that Intel Security will be discontinuing McAfee SaaS Email Protection products, SpamTitan is preparing for 2016 when business customers start looking for a new email security vendor to ensure continued protection.

McAfee SaaS Email Protection to Come to an End

Intel Security, the new company name for McAfee, has taken the decision to exit the email security business. The company will be dropping McAfee SaaS Email Protection products and will be concentrating on other areas of business.

From January 11, 2016, McAfee SaaS Email Protection and Archiving and McAfee SaaS Endpoint will stop being sold by Intel Security. The news is not expected to trigger a mass exodus in early 2016, as Intel Security has announced that it will continue to provide support for the products for a further 3 years. Support for both McAfee SaaS Email Protection and Archiving and SaaS Endpoint will stop after January 11, 2019. However, many customers are expected to make the switch to a new email security provider in the new year.

Healthcare Industry Phishing Report: Greater Email Security Required

In the United States, healthcare industry phishing campaigns have been responsible for exposing the protected health records of well over 90 million Americans over the course of the past 12 months. That’s over 28% of the population of the United States.

This week, another case of healthcare industry phishing has come to light with the announcement of Connecticut’s Middlesex Hospital data breach. The hospital discovered four of its employees responded to a phishing email, resulting in their email account logins being sent to a hacker’s command and control center. In this case the damage caused by the phishing attack was limited, and only 946 patients had their data exposed. Other healthcare organizations have not been nearly so lucky.

Largest ever healthcare industry phishing attack suffered in 2015

In February, Anthem Inc., the second largest health insurance company in the United States, discovered it had suffered the mother of all healthcare data breaches. Approximately 78.8 million health insurance subscriber records were obtained by criminals in the attack. The breach did not occur in February, but months previously, with the hackers being allowed plenty of time to exfiltrate data.

Another U.S. health insurance company discovered it too had been hacked just a couple of weeks later. Premera Blue Cross similarly found out that hackers had gained access to its systems many months previously and had potentially obtained the records of over 11 million insurance subscribers.

Both security breaches were highly sophisticated in nature, but were discovered to have their roots in healthcare industry phishing campaigns. Employees had responded to phishing emails which ultimately allowed hackers to gain access to huge volumes of highly confidential healthcare data.

In 2014, Community Health Systems suffered a data breach that exposed the PHI of 4.5 million individuals in what was then the second largest healthcare data breach reported. That data breach had its roots in a phishing campaign sent to its employees.

Healthcare industry phishing attacks occurring with alarming frequency

In just 12 months, many healthcare providers and health plans have suffered at the hands of phishers. Some of the healthcare industry phishing attacks have been summarized in the table below:

Successful U.S. Healthcare Industry Phishing Attacks in 2015

Company Records Exposed
Anthem Inc. 78,800,000
Premera Blue Cross 11,000,000
CareFirst Blue Shield 1,100,000
Seton Healthcare 39,000
Saint Agnes HealthCare 25,000
Partners Healthcare 3,300
Middlesex Hospital 946
St. Vincent Medical Group 760

 

Cybercriminals attracted by easy targets and big rewards

In the United States, healthcare organizations and their business associates are covered by legislation which requires robust protections to be put in place to keep computer networks secure and patient health data safeguarded from attack. The Health Insurance Portability and Accountability Act (HIPAA) requires administrative, technical, and physical controls to be used to keep the Protected Health Information (PHI) of patients secure at all times.

Even though the industry is heavily regulated, the industry lags behind others when it comes to data security. Hackers often see healthcare organizations as an easy target. Their networks are complex and difficult to protect, and IT security budgets are insufficient to ensure that all of the appropriate protections are put in place to keep data secure.

On top of that, healthcare providers and health insurers store an extraordinary volume of highly sensitive data on patients and subscribers. Those data are much more valuable to thieves than credit card numbers. Health data, Social Security numbers, and personal information can be used to commit identity theft, medical fraud, insurance fraud, credit card fraud, and tax fraud. One set of patient data can allow criminals to fraudulently obtain tens of thousands of dollars, and the data can typically be used for much longer than credit card numbers before fraud is detected.

It is therefore no surprise that healthcare providers are such a big target. There are potentially big rewards to be gained and little effort is required. Healthcare industry phishing is therefore rife, and spear phishing campaigns are now increasingly being used to get busy healthcare employees to reveal their login credentials. Many of those campaigns are proving to be successful.

Industry reports suggest that the healthcare industry in the United States does not have sufficient controls in place to prevent against phishing attacks. A KMPG study conducted earlier this year showed that 81% of U.S. healthcare organizations had suffered cyberattacks, botnet, and malware infections. Other research conducted by Raytheon/Websense suggested that the healthcare industry in the United States suffered 340% more data breaches than other industries.

Healthcare industry phishing emails are not always easy to identify

Just a few years ago, a phishing email could be identified from a mile away. They contained numerous spelling mistakes and grammatical errors. Nigerian 419 scams were commonly seen and easily spotted. Malicious email attachments were sent, yet they could be easily identified as they were rarely masked. It is easy to train staff never to open an executable file sent via email.

Today, it’s a different story. Healthcare industry phishing emails are not always easy to identify. Malicious emails are crafted with a high level of skill, spell checks are used, subjects are researched, as are the targets. Links are sent to phishing websites that cybercriminals have spent a lot of time, money, and resources developing. Even a trained eye can have trouble identifying a fake site from a real one. The threat landscape has changed considerably in just a few years.

Sometimes healthcare industry phishing emails are so convincing that many members of staff are fooled into responding. Franciscan Health System is a good example. In 2014, a phishing campaign was sent to the healthcare provider via email. The scam was straightforward. Workers were sent an email containing a link and a good reason to click it. They clicked through to a website which required them to enter their login credentials. 19 workers reportedly fell for the campaign and revealed their email account login names and passwords. Contained in their email accounts were patient data. As many as 12,000 patients were affected.

What can be done to reduce the risk of phishing attacks?

There are a number of controls and safeguards that can be implemented to reduce the risk of healthcare industry phishing campaigns being successful, and multi-layered defenses are key to reducing risk.

Conduct Regular Staff Training

All members of staff should be trained on email and internet security, and told how to identify phishing emails and phishing websites. They must be issued with a list of best practices, and their knowledge should be tested. The sending of dummy phishing emails is a good way to check to see if they have taken onboard the information provided in training sessions.

Use Powerful Anti-Virus and Anti-Malware Software

Separate anti-virus and anti-malware solutions should be used and virus/malware definitions updated automatically. Regular scans of the network and individual devices should be scheduled at times of low network activity.

Employ Spam Filtering Software

Spam filtering solutions are essential. One of the best ways of preventing end users from falling for phishing emails is to make sure they never receive them. Powerful anti-spam solutions will block and quarantine malicious email attachments and prevent phishing emails from being delivered to end users.

Implement Web Filtering Solutions

Not all phishing campaigns come via email. Social media websites are often used as an attack vector and malicious website adverts can direct users to phishing websites. Implementing a web filter to limit the types of websites that users are permitted to visit can significantly reduce the risk of users falling for a phishing campaign. Web filtering solutions will also block access to known phishing websites.

Chimera Ransomware Raises Stakes to Get Victims to Pay Up

Criminals are increasingly using ransomware – Chimera ransomware for example – to extort victims. Ransomware encrypts certain file types with a powerful algorithm that cannot be unlocked without a security key. Unfortunately, the only person to hold that key is the hacker responsible for the ransomware infection.

Organizations and individuals that perform regular data backups can avoid paying the ransom demands and not face losing important files. If files are encrypted, they can be recovered from backups – provided of course that regular backups of critical data have been performed. Worst case scenario: Some data may be lost, but not a sufficient amount to warrant a ransom being paid.

Criminals are aware of this failsafe and have recently started to up the stakes. The criminals behind Chimera ransomware have been found to be using a new tactic to scare victims into giving into their demands. Even if a backup file has been made, victims can be easily convinced to pay the ransom. They are told that if the ransom is not paid, the files will be made public. Confidential information will be posted on darknet sites or listed for sale in online marketplaces.

Criminals Target Businesses and Encrypt Critical Files Using Chimera Ransomware

Hackers are known to send ransomware out randomly. The more computers that are infected; the more ransoms can be collected. Chimera ransomware on the other hand is being used more specifically, and small to medium sized businesses are being targeted. This stands to reason. An individual may not be willing, or able, to pay a ransom. Businesses are different. They may have no choice but to pay to have files unlocked. If data are posted online, the potential cost to the business could be far higher than the cost of the ransom.

How are computers infected with Chimera ransomware?

Spam emails are sent to specific individuals within an organization. Those emails contain innocent looking email attachments: the types of files that would commonly be received by the individuals being targeted. Business offers are sent, applications for employment, or invoices.

Attachments may not be opened or could be blocked by spam filters. To get around this issue, hackers often send links to cloud-storage services such as Dropbox. The user clicks the link and downloads the malware thinking it is a genuine file.

Once installed the malware gets to work encrypting files stored on local and mounted network drives. The user is not made aware of the infection until their computer is rebooted. In order to unencrypt files, the end user must pay the ransom. This is typically $500 in the form of Bitcoins.

It is not known whether hackers have acted on their threats to publish company data. Many businesses have been too scared to find out and have given in to the ransom demand.

How to protect your business from Chimera ransomware

There is no such thing as 100% protection from Chimera ransomware, but it is possible to reduce the risk of infection to a minimal level. Installing Anti-Spam solutions can prevent malware from reaching inboxes; however not all products offer protection from phishing links.

SpamTitan software on the other hand employs a powerful spam filter which uses dual AV engines to maximize the probability of malicious emails being caught. It also includes an anti-phishing module to protect against phishing links. If you don’t want to have to pay a ransom to recover your data, installing SpamTitan is the logical choice.

Are you protected from Chimera Ransomware? Would you risk the publishing of your business data or would you pay the ransom?

SpamTitan Technologies One of World’s Most Innovative Cybersecurity Companies

Ireland may not produce many highly innovative cybersecurity companies, but Galway-based SpamTitan technologies is bucking that trend. The company has recently been rising up the ranks and has now taken its place among the best cybersecurity companies in the world, according to the latest Cybersecurity Ventures report.

Only four Irish companies have made it into the Q2 2015 edition of the Cybersecurity Ventures Cybersecurity 500 list: Netfort, PixAlert, VigiTrust and SpamTitan Technologies, with SpamTitan now having ascended to position 123.

This is a major achievement, with the company having previously been placed at 393 for the previous quarterly report. The massive jump in position has been attributed to the hard work put in by all members of staff, who are committed to providing the best possible service in the fight against cybercrime. The company can now be considered one of the best, and also one of the hottest new prospects in the world of cybersecurity.

Each quarter, Cybersecurity Ventures publishes its new top 500 list, which features companies from all around the world. Experts in the field of cybersecurity assess companies for the efforts made, as well as determining each company’s potential. CISOs, VCs and a host of security professionals provide their input for the reports.

Many similar reports tend to focus on the size of the company, turnover and profits achieved. This list is different as it is more concerned with potential and innovation. Founder and CEO of Cybersecurity Ventures, Steve Morgan, said, “We do not think a list of the largest cybersecurity companies is useful to our target audience of cyber and IT security decision makers, evaluators, and recommenders”. He went on to say, “They already know who the biggest vendors are. Instead, we give a nod to the hottest and most innovative companies.” It is, after all, these companies that really need the recognition.

The list contains all of the hottest new prospects and top performers, with the ranking based on each company’s merits and prospects. Ronan Kavanagh, CEO of SpamTitan Technologies is proud of the rise in position, and the value of the list. After hearing of the new position in the top 125 cybersecurity companies, he said, “We recognize the importance of being included on such a significant industry list as the Cybersecurity 500.” He went on to say, “At SpamTitan, our staff are assisting our customers on a daily basis in dealing with the constant threat of cyber attack, and this is now as important for the smaller businesses as it is for the fortune 500 company. We are delighted to be working with Cybersecurity 500 in highlighting the need for vigilance and raising awareness for all businesses.”

Prevent Cyberattacks with Effective Password Management

Passwords are used to prevent unauthorized individuals from accessing accounts, services and software. They keep data and networks secure, they prevent bank accounts from being plundered and ensure only one person can access sensitive information. If passwords are obtained by a criminal, this excellent security measure is worth absolutely nothing.

The daily news is full of stories about companies that have had their security perimeter breached and usernames and passwords stolen. Keyloggers are installed that obtain passwords, and accounts are bombarded by robots trying combination after combination until the right sequence of numbers and letters is found. Dark net marketplaces list passwords for sale by the thousand, and username and password combos can be purchased for just a couple of dollars a set.

How do passwords actually get stolen?

There are many techniques that are used and a myriad of ways that passwords can be obtained. Some of the most common methods are details below:

Keyloggers – Installed on users’ computers via malicious websites and infected email attachments. They record keystrokes and transmit the information to a hacker’s command and control server

Phishing – Users give passwords away by responding to phishing campaigns

Hacking – Security vulnerabilities in websites are exploited and the Active Directory or LDAP database is stolen

Social Engineering – People give their login credentials to bogus callers, fake customer service personnel, or via IT support scams

Is it so easy for hackers to steal passwords?

Sometimes it can be, but oftentimes security controls prevent a username and a password from being obtained. Passwords are often hashed to prevent this. A login name is obtained, and the number of characters in a password, but not the actual password itself as it is often encoded. The hacker must decode the passwords before they can be used.

What is Password Encoding?

There is a big difference between encoding and encrypting. If data are encrypted, they cannot be unlocked without a security key. This is why ransomware is so effective. Once encrypted, data is inaccessible unless a security key is entered. Security keys cannot be guessed.

Encoding is different. The single data field is encoded using an algorithm that hashes the password. When a password is entered, the hashing algorithm checks the text against the stored hashed version of the password. If the two match, access to an application is granted.

So how are passwords guessed?

In UNIX, a hashed password is stored in an LDAP system, but the type of algorithm that was used to encode the password is also stored. The hacker can work out the password if they have a dictionary of hashed values corresponding to the algorithm used.

The dictionary can be searched to find out if there is a match. These dictionary attacks will not reveal every password, but they can identify some of the most common words used for passwords.

A dictionary can be created by running common words through the algorithm. If you run the word “password” through an MD5 encoding algorithm, the hash it produces will be the same as any other system that uses MD5 encoding. This is how passwords are often guessed. It is not a hacker sitting at a computer entering in different combinations one after another in the hope he or she gets lucky. They can quickly run hashed passwords through their dictionary. Many will be revealed.

This is why it is essential that common passwords are always avoided. “Password”, “123456”, “bigguy”, “administrator” etc. It is also why it is important to use more than a few characters. How long would it take a hacker to compile a list of hashed two digit passwords? By the time you get up to 6 or 8 digits, the possible combinations are too numerous to compute. Since hashing allows up to 255 characters, it is not realistic for a super dictionary to be created. However, since many people use common words, and most use 5 or 8 digit passwords, a surprising number can be very rapidly guessed.

If you also use a common word you are asking for trouble, and if you also share passwords across multiple accounts, everything will be compromised if one is guessed.

Top 5 Spam Catching Ranking and VBSpam+ Certification for SpamTitan

There is good news for users of SpamTitan Technologies’ anti-spam solutions. The company’s innovative solutions for dealing with email spam have been awarded VBSpam+ certification from Virus Bulletin. The Virus Bulletin anti-spam software tests are widely regarded to include some of the email security industry’s most rigorous tests, and the results are trusted by industry professionals and users alike.

The anti-spam award is only issued to companies whose spam solutions are shown to be effective in practice. Any product that fails to block sufficient volumes of spam emails will not receive accreditation. SpamTitan has performed consistently will in Virus Bulletin Tests, and this is the 28th consecutive time that the company has received an anti-spam ranking from the bi-monthly tests run by Virus Bulletin.

In contrast to previous tests, Virus Bulletin has assessed products on two counts this time around. Spam catch rates were examined in addition to the number of false positives. Overactive anti-spam products that block genuine emails can cause many headaches for businesses. Any email that is incorrectly blocked could potentially mean the loss of a client. It is therefore essential for an anti-spam solution to have a very low false positive rate.

When tested in May 2014, SpamTitan registered 0 false positives. In March when the test was last run, SpamTitan also registered a false positive rate of 0. These results were among the best recorded for all email spam solutions tested by Virus Bulletin. In fact, SpamTitan has only recorded one false positive result since November 2013, demonstrating the consistency of the product. It continues to deliver industry-leading standards of spam-detection. Users of the product also benefit from an extremely competitive pricing model.

SpamTitan Demonstrated a Spam Catch Rate of 99.81%

The May 2014 test for spam blocking saw SpamTitan register a catch rate of 99.81%, with only a slight drop registered since the test was last performed in March, when 99.85% of spam emails were blocked. The consistent results and superior spam-blocking also saw the company receive its fourth VBSpam+ award for exceptional performance. This earned the company a position in the Top 5 anti-spam products under test. The spam-catching percentages achieved over the past months have also been very high, with the lowest rating being 99.73% (January 2014.)

CEO of SpamTitan Technologies, Ronan Kavanagh, was proud of the high ranking and spoke of the importance of having an independent third party conduct performance tests. He pointed out that the Virus Bulletin test results can be trusted as they have no bias. Organizations looking to deploy an anti-spam solution can therefore rely on the results and choose accordingly. Companies already using anti-spam software can also view the results to assess how well their chosen product fares against the competition.

An anti-spam solution must be effective, as any spam emails that get past the filter could potentially result in a phishing email being delivered to an employee. The high catch rate shows the quality of the product that uses not one but two different anti-virus engines to ensure dangerous emails prevented from being downloaded and delivered to end users.

Network Security Decision Maker? What Should be Your Main Focus?

If you are a network decision maker, what should be your main focus? Which issues should demand your attention? This post covers five important considerations if you want to protect your critical assets.

The current threat landscape has become very serious

If you work in a large corporation, chances are you will not need to be reminded about the seriousness of the current threat landscape. However, if you work in an SME, the severity of the current situation may not be so apparent. According to the results of the 2012 Verizon Data Breach Investigations Report (DBIR), the main threat of data theft comes not from hackers intent on profiting from selling stolen data, but from hacktivist groups. In 2011, hacktivists were behind 58% of data breaches. Hackers were involved in 81% of all data breaches reported throughout the year.

One of the main issues in 2014 are what Verizon calls “low and slow attacks.” These are authentication attacks, web exploits and social engineering-based attacks. Malware is evolving and carries a much higher risk than when many companies deployed their security systems. The threat landscape is constantly changing and you must stay alert to the changing risks.

Corporate data is one of your biggest assets – Protect data like you protect your financial assets

Company data is incredibly valuable to cybercriminals. Credit card numbers (with expiry dates, holder names and CSCs) sell for up to $6 a set. If hackers obtain several hundred or several thousand, they can make a tidy profit. If Social Security numbers can be obtained, in particular those of minors, they can sell for up to $200 a set, especially if accompanied by medical records. Bank account information is also valuable. Account information can be sold for up to 10% of the balance of the account. As for proprietary company data, to the right person that could be sold for millions of dollars. Data is highly valuable and criminals will attempt to steal it. You must therefore ensure it is appropriately protected.

End users are actually the first line of defense

Firewalls and other systems designed to repel DDoS attacks and stop malware from being installed may be seen as the first line of defense; however, your end users are actually the first line. They are also the weakest link in the security chain, and cybercriminals know it. Many criminals target end users as it is easier to get them to download malware or reveal login credentials than to break through a firewall.

If you want to keep your network secure you must provide training and make end users more security aware. They must be instructed how to identify phishing campaigns, be shown good practices to adopt when surfing the Internet or using email. Social media best practices must also be taught, especially if access to the websites is not blocked.

Application and platform management policies need to be developed

In order to protect networks and connected devices from being infected with malware and viruses, policies must be developed covering the permitted uses of computer equipment, applications, Smartphones and other BYOD devices.

Even some companies that have adopted BYOD have not issued staff members with detailed policies on the allowable uses of their devices in the workplace. SpamTitan recently conducted a research study that showed a third of organizations have not covered the use of messaging and collaboration tools in their corporate policies. Make sure the use of Smartphones, tablets, portable storage devices, collaboration tools, email, Social media, and web 2.0 applications are all covered. This will help to ensure staff do not take unnecessary risks.

Prohibition didn’t work – Neither do blanket bans

Total bans on the use of Smartphones, laptops, social media, or online shopping at work will not prevent end users from bringing their devices to work or using the Internet for personal use. Controls such of these may actually have a negative impact on staff happiness and productivity. Many employers believe the reverse is the case and issue total bans. Controls must be implemented to prevent theft of data, but carefully consider blanket bans. They may sometimes be effective at protecting networks, but they are rarely good for the business.

Russian Snake Virus: 8 Years of Data Theft by Uroboros

How long are computer viruses active before they are discovered? A few months? A year? In the case of the Russian Snake Virus, Uroboros, it has been stealing data for 8 years. It has been detected, but that doesn’t mean that the threat is over. The virus will be present on many systems, and will continue to steal data as it is incredibly difficult to detect.

Where did the virus come from?

It has been called the Russian Snake Virus, as many researchers believe the virus was created in Russia. Snake because some believe the Russian government had a hand in its creation. Why? Because of the sophisticated nature of the virus. A malicious program as complex as Uroboros is believed to have required state sponsorship. Foreign governments have been known to create viruses before. China was behind the APT1 virus. Links have been uncovered that tie the virus to the Chinese military. However, so far no link has been proven between the Russian government and Uroboros.

The virus was not created to steal data from individuals. The creators had other loftier aims. The International Business Times reported that the virus was created to steal government secrets and strike at telecoms systems.

The exact targets have not all been announced by the researchers who discovered the virus, but another link to Russia comes from the fact that Ukraine was attacked 14 times by Uroboros. It would appear that the Department of Defense of the United States was also attacked by the Russian Snake Virus in 2010.

The virus is currently being analyzed by UK firm BAE and German company Gdata. As for the level of sophistication, it is reportedly equivalent to Stuxnet. For anyone unaware of Stuxnet, it was developed and used by the U.S. and Israel to destroy Iranian nuclear reactors. It caused them to spin out of control until they were destroyed. Very James Bond, but in this case very real.

Uroboros is a rootkit and hides inside kernel-level processes. Because of this it has remained undetected. Anti-Virus engines do not scan there, allowing it to remain undetected for so long.

The analysis of Uroboros by BAE is secret and, while more is now known, since the virus is part of an ongoing operation few details have been released. The virus is still in operation and may be attacking or monitoring foreign government systems right now. What is known is Uroboros targets a vulnerability in Windows in addition to software running on the Windows platform. The virus has managed to continue working despite new security features being incorporated into the operating system.

How does Uroboros work?

From the information released so far it is known that Uroboros hijacks a running process. It hides inside of processes that are part of Windows so evades detection. Because of this, AV engines do not detect it. The AV software assumes it is part of Windows, and fails to flag the virus or hijacked service as being malicious. The virus is understood to inject DLLs into the running process.

It sends data at the user and kernel level. When a user fires up their browser, the virus launches a GET request and obtains instructions from the hacker’s command and control center. Since hundreds of legitimate requests are usually made, the GET request from the virus remains hidden. The use of HTTP also allows it to bypass firewalls. Uroboros is not always active either. It may be for a short period of time before going to sleep. It is told to do this by the hacker in control of the virus, and may sleep for months if required.

One question that has not been answered is how the Russian Snake Virus infects a computer. According to BAE, Uroboros is installed by a USB plugged into a computer, but it may also be installed via a phishing email. It is known to hack network processes, and monitor and intercept inbound and outbound traffic. It is capable of exfiltrating data and logs and can receive inbound commands.

A security vulnerability in Oracle Virtualbox has been exploited by the virus, allowing access to be gained to the kernel memory. It updates a variable indicating Windows was started in WinPE mode. Unsigned DLL files can then be loaded. These files do not have their owner and integrity verified. The Russian Snake Virus is capable of mounting virtual and physical drives, and different versions exist allowing it to be installed on different operating systems.

How can an attack of this nature be avoided?

Unfortunately, with malicious software such as the Russian Snake Virus it is difficult to totally protect a computer. There are steps that can be taken to reduce the likelihood of infection:

  • The virus may be transmitted via phishing and spam emails: Block these using Anti-Spam software
  • Issue training on anti-phishing strategies to employees
  • Ban the use of all USB drives in your organization
  • Keep software systems up to date with patches and, better still, upgrade Windows to the latest version
  • Use diskless devices such as Chromebooks as much as possible
  • Ensure packet-level inspections read HTTP traffic to look for signals that malware or viruses are communicating with command and control servers
  • Data encryption can be used to protect stored data, but unfortunately not the memory

The Russian Snake virus: A risk for everyone or just foreign governments?

At present, the virus is believed to be used to attack foreign governments. Unfortunately, when details are released they can be used to create variants. Non state-sponsored hackers may not have been able to create the virus, but the techniques used to exploit computers and networks can be copied. This may already have occurred.

The next few years may see a number of different versions of the virus discovered, which may be used for many different reasons. Specific data may be targeted and stolen, or systems sabotaged. Only time will tell.

The discovery shows the lengths that some individuals and groups will go to in order to steal data, and why it is essential to implement multi-layered security systems to protect computers and computer networks, and always to use controls to prevent phishing emails from being delivered, and responded to.

One in Five Phishing Scams Target Bank Customers

Phishing is not a problem that must only be dealt with by consumers. Businesses are being targeted based on the financial organizations they use, according to the latest research conducted by Kaspersky Labs. The Anti-Virus software provider has been investigating the evolution of phishing. The study looked at the attacks that had taken place between May 2012 and April 2013. The survey revealed that phishers are changing tactics, and are attempting to obtain bank account information. If business bank accounts can be obtained, so much the better. They usually contain much more money than personal accounts.

Hackers often target businesses they despise. Their intention is not always to make money but to cause harm. If bank accounts can be obtained they can be sold to cybercriminals. Accounts are plundered, and sometimes businesses go bust as a result. You may not have offended any hackers, but that doesn’t put you in the clear. Some hackers are involved in organized crime and they will not care who they target as long as money can be obtained.

If a bank is targeted and you lose funds, can you sue them?

A bank is attacked and a business loses money from its account. Can a business sue a bank for a cyberattack? Some are now trying.

EMI has filed a lawsuit against Comerica, in which it claims that the financial institution failed to implement appropriate security defenses which directly led to one EMI employee falling for a phishing campaign. An employee was tricked into revealing EMIs bank account details. As a result, over $500,000 was rapidly transferred out of EMIs accounts. Protections were not in place at the bank to stop this.

Unsurprisingly, the bank has claimed that this was the fault of EMI. It is EMIs responsibility to ensure its employees are trained, and do not fall for phishing campaigns. The bank could have done nothing to prevent that employee from falling for the phishing scam. EMI could have taken action though. It is unlikely that the lawsuit will result in the bank having to cover the losses of EMI.

Phishing prevention starts with staff training

If you want to protect your company’s bank balance, and stop phishers making transfers, the first step to take is to provide all staff members with cybersecurity training. One response to a phishing email is all it takes to see a bank account emptied. It therefore makes a great deal of sense to instruct members of staff about phishing emails. In the above case, the provision of such training may have saved $500,000.

The FBI estimates that these schemes, and other cyberattacks, net online criminals around $100 billion a year. These funds are obtained from large corporations and individuals, but small businesses are now being increasingly targeted. They lack the security software used by large corporations and their bank accounts contain more money than consumer accounts.

Unfortunately for SMEs, the same protections are needed as those used by large corporations. Unfortunately, IT budgets are not nearly as large. SMEs must therefore choose the best protections to put in place that will offer the greatest protection for the least outlay. Many do not even employ dedicated cybersecurity staff, so the products they choose must be easy to install, operate and maintain.

To protect against phishing, businesses must concentrate not on protecting their network with firewalls, but protecting end users. They are the ones who will be targeted by a phishing attack.

There are two methods that can be used in this regard (apart from staff training): The use of a spam filter to prevent phishing emails from being delivered, and a web filter to stop users visiting phishing websites.

The number of phishing attacks has increased significantly over the course of the past year. Because the tactic is proving to be so profitable, 2013 and 2014 are likely to see even more attacks take place. Any business that fails to take action to address the risk is likely to become a victim. Maybe not today, maybe not tomorrow, but soon.

Cybercriminal Activity Increases During Holiday Season

Halloween has been and gone, and with it the threat from Halloween-related spam and phishing campaigns. Unfortunately, the ghoulish behavior of cybercriminals will not stop. They will just work on Thanksgiving-related scams, or target the millions of online shoppers on Black Friday, Cyber Monday and Free Shipping Day. They will also be preparing for Christmas, which is another excellent time to target the unwary and gullible. All of these holiday times see millions of spam emails sent, new phishing campaigns developed, and many old ones dusted off and used again. Internet users must therefore always be constantly vigilant for the next cyberattack or scam.

Internet security risks increase in the run up to Christmas

Employees lead busy lives and often do not find the time to do all of their Christmas shopping at home. Some do not have home computers so are unable to access the Internet outside office hours. Many just prefer to keep their free time free, and be paid by their employers to do their Christmas shopping.

Unfortunately, those employees are taking big risks that could seriously jeopardize the security of their corporate computer systems, according to the Information Systems Audit and Control Association. This risk naturally increases at times of the year when internet shopping increases.

The risk has also increased in recent years with the rise in popularity of BYOD. More devices are being used to access networks, many of which do not have the level of security of the desktop computers supplied by employers and configured by IT departments. These devices make it much easier for employees to bypass security and spam protection controls.

The bad news is the risk is not going to decrease. As more users take part on BYOD, and even more devices are allowed to connect to corporate networks, the risk of suffering network security breaches will also increase.

Many companies find the number of employees using computers for personal use, especially in the run up to Christmas, has reached a level where it is simply not possible to take action against each employee. The threshold for disciplinary action has had to be increased. Others target this by taking a much harder line, due to the amount of time that is being wasted by employees. HR departments are then run ragged.

It is no surprise that many employers opt for an easy solution and implement a web filter to block access to certain internet sites. The burden is eased on HR staff and employees waste less time and become more productive. They are also used to cut back on other time wasting activities, such as accessing social media sites and playing online games.

A web filtering solution, such as WebTitan, can be invaluable at this time of year. It will reduce risk to network security and improve productivity; however, risk cannot be totally eliminated especially with the volume of email spam campaigns and Christmas-related scams seen at this time of year.

Holiday season scams that threaten network security

The usual suspects come out at this time of year but, after 10 months’ “holiday” from Christmas scam emails, it is useful to remind employees of the spam and phishing emails that do the rounds at this time of year.

‘Must Have’ Gift Scams

Every year there are some gifts that every child wants. They are in short supply and usually sell out well before Christmas. Be late buying Christmas gifts and your child will have to make do with second best. UNLESS…… someone has a spare one or some excess stock. You will find offers of the latest gadgets or hot new products flood inboxes. Links take users to shopping websites that have just one or two left. A purchase is made and the gift is mailed. Unfortunately, many of these websites are fake, and all that happens is a credit card number is divulged to a criminal.

Christmas Phishing Scams

The run up to Christmas is a busy time and short cuts are taken by employees who are under pressure or daydreaming about roast turkey. People are less cautious and take more security risks. They forget to check that a website has a valid SSL Certificate or shows a padlock next to the URL. People are more likely to click on links to malicious websites and, when full of Christmas spirit, Christmas-related social media posts are visited more frequently. Users tend to reveal personal information at this time of year. A post asks you to create your Elf name by using the name of your first pet and the street where you grew up. Users unfortunately divulge the answers to their online banking security questions all too easily.

Fake Special Offers and Competitions

Everyone would like a free Christmas gift, and scammers know it is easy to obtain sensitive information via fake competitions if there is a cool prize on offer. It is a time to be very cautious about surveys or competitions that ask for personal information. Facebook is one of the preferred websites to launch a fake contest, and it is surprising how much personal information is disclosed. Once personal information has been divulged, an email often arrives offering a prize. Just a few more data fields need to be entered to claim the top prize. That prize is identity theft, not a shopping voucher or an Xbox.

How to avoid these Christmas scams

Vigilance is key. Employers must be particularly careful that their staff members do not fall for these scams. It is a great time for refresher training to be conducted or for an email bulletin to be sent. Be sure to warn the staff of the following:

  • Never to click on a link contained in an email unless they are 100% sure of the identity of the sender
  • Never open an attachment in an email from someone they don’t know
  • Change passwords and make sure they are impossible to guess
  • Be very careful about divulging sensitive information to anyone
  • Social media websites contain many scams. Make employees aware of scam competitions or surveys that request personal information
  • Be careful about installing mobile apps – they may not be as harmless as they appear
  • Password protect Smartphones and use a lock screen – if stolen, criminals will not be able to access online accounts and company data

Stop and think before clicking any link, visiting a website or opening an email – Could it be a scam or phishing attempt?
