The Healthcare Sector is Targeted by Cybercriminals More than Ever

The healthcare sector has recently become a desirable target for cyber crooks. According to Symantec ISTR report statistics, healthcare was the most breached sub-sector in 2015, comprising almost 40% of all the attacks. Hospital security systems are generally less secure than those of financial organizations, as monetary theft has always been perceived as the greatest threat for organizations, and dangers to other sectors were usually underestimated. Moreover, awareness of cyber-attacks against hospitals and medical centers is much lower than it is to financial cybercrime, and as a result, the employees are less well-trained on how to avoid falling victim to a cyber-attack.

Top 10 Sub-Sectors Breached by Number of Incidents According to Symantec ISTR report

Only lately, this concept has started to be challenged, revealing the potential damage that can be caused by the theft and leakage of patient data. However, the ‘bad guys’ remain one step ahead and during the last few months, we have witnessed a spate of attacks targeting the healthcare industry: ransomware attacks encrypting essential data and demanding payment of a ransom, numerous data leakages revealing confidential patient data, unauthorized access to medical networks and even the hacking of medical devices, such as pumps and X-ray equipment.

Moreover, the healthcare sector is being targeted by hackers not only directly, but also via third-party companies in the supply chain, such as equipment and drug suppliers. These companies usually store some confidential data that originates in the hospitals’ databases and may even have access to the hospital IT systems, but they are far less secure than the hospitals themselves. Thus, they serve as a preferable infiltration point for malicious actors pursuing the theft of medical data and attempting to infiltrate the hospitals’ networks.

The consequences of attacks on the healthcare industry may be extensive, including the impairment of the medical center functioning, which may result in danger to human lives in the worst case scenario. In other cases, personal data will be stolen and sold on underground markets. Cybercriminals will take advantages of these personal details for identity theft or for future cyber-attacks combining social engineering based on the stolen details.

While monitoring closed Deep-Web and Darknet sources, SenseCy analysts recently noticed a growing interest toward the healthcare sector among cyber criminals. Databases of medical institutions are traded on illicit marketplaces and closed forums, along with access to their servers. In the last few months alone, we came across several occurrences indicating extensive trade of medical records and access to servers where this data is stored.

The first case, in May 2016, was the sale of RDP access for a large clinic group with several branches in the central U.S., which was offered for sale on a Darknet closed forum. For a payment of $50,000 Bitcoins, the buyer would receive access to the compromised workstation, with access to 3 GB of data stored on four hard disks. Additionally, the workstation allows access to an aggregate electronical system (EHR) for managing medical records, where data regarding patients, suppliers, payments and more can be exploited.

Although the seller did not mention the origin of the credentials he was selling, he claimed that local administrator privileges could be received on the compromised system. He also specified that 45 users from the medical personnel were logged into the system from the workstation he hacked.

The relatively high price for this offer indicates the high demand for medical information. With RDP access, the potential attackers can perform any action on the compromised workstation: install malware, encrypt the files or erase them, infect other machines in the network and access any data stored in the network. The consequences can be tremendous.

Just a few weeks later, in June 2016, our analysts detected another cyber-accident related to healthcare. This time, three databases allegedly stolen via an RDP access to a medical organization were offered for sale for more than $500,000 on a dedicated Darknet marketplace. In one of his posts, the seller claimed that one of the databases belongs to a large American health insurer.

Screenshot posted by the seller as a proof of hacking into a medical organization

Before long, we again discovered evidence of hacking into a medical-related organization, this time by Russian-speaking hackers. On one of the forums we monitor, a member tried to sell an SSH access to the server of an American company supplying equipment to 130 medical center in the U.S. He uploaded screenshots proving that he accessed the server where personal data of patients is stored.

The conclusions following these findings are concerning. An extensive trade in medical information and compromised workstations and servers is a common sight on underground illegal markets. This business generates hundreds of thousands, if not millions of dollars annually, ensuring its continuation as long as there are such high profits to those involved. Since the ramifications can be grave, the healthcare sector must take all necessary measures to protect their systems and data:

  1. Implement a strong password policy, because many hacks are a result of brute-force attack. Strong passwords and two-factor authentications to log into organizational systems should be the number one rule for medical organizations.
  2. Deploy suitable security systems.
  3. Instruct the employees to follow cyber security rules – choosing strong and unique passwords, spotting phishing email messages, avoiding clicking on links and downloading files from unknown sources, etc. Consider periodic training for employees on these issues to maintain high awareness and compliance with the rules.
  4. Use Cyber Threat Intelligence (CTI) – to keep up with the times regarding the current most prominent threats to your organization and industry.
  5. Keep all software updated.

Brazilian Trojans Poised to Spread around the World

When we talk about Brazil, we no longer think only Carnival and caipiriña, or the favelas (slums) that came into being as a result of the highly unequal distribution of income. Bearing in mind that Brazil is one of the largest countries in the world, a major new concern has arisen as the Internet and technological devices are being used to find fast ways to earn money.

In 2014, Brazil was listed as the country with the most number of attacked users. Kaspersky identified over 90,000 attacks in Brazil, with Russia in second place.

Brzail_number_of_attacksCybercrime has combined the creativity of Brazilian hackers with new forms of illegal activities, specifically online bank fraud, turning the country into a producer of Trojan malware. The increased variety of Trojans produced in Brazil is becoming a trend. Hackers are spreading their tools via hacking communities, by selling or simply sharing tools, tutorials and tips for using Trojans as a means to intercept information on users and their banks. They use social network platforms, personal blogs or “security information web sites,” IRC channels and the forums on the deep web where “laranjas” (oranges in Portuguese, used to denominate a tool/card trader) do business to sell the malware or the stolen data.

While hackers from other countries use malware tools such as Zeus, the uniqueness of the Brazilian hackers is that they develop specific, personalized codes targeting banking frauds. They also find creative ways to use software to access their targets, with the aim of stealing bank accounts. CPL is one of these innovations – a legitimate Windows Control Panel file is being used by cybercriminals to spread banking Trojans targeting Brazilian users.

Cybercriminals send fake emails, using social engineering techniques designed to mislead users. Usually, the email content is a document with a quotation, invoice or receipt, information on a debt or a banking situation, or digital payment instruments used in Brazil, such as Boleto bancário or Electronic tax note, file photographs, videos or similar.

The fact that Brazil has the highest percentage of online banking users has also contributed to the development of different personalized attacks. As a result, banking Trojans have become the number one threat in Brazilian cybercrime. As previously demonstrated in the Brazilian malware arena, some code writers spread their viruses around the world. The security sector, in this case the banking sector, must be aware of the possible dangers and increase their efforts to protect their clients.

Shell Profiles on the Russian Underground

Russian underground cyber-markets are known venues for purchasing high-quality hacking tools and services. Many such tools, popular worldwide, make their first appearances on closed Russian forums. There are two main types of sellers on these platforms: well-known members with seniority and strong reputations, who have already sold tools and received positive buyer feedback, and an emerging “shell profile” type of user. According to our recent analysis, such users typically register to a forum a few days before posting an advertisement for the tool. These new users often enlist the aid of forum administrators and more senior members, by providing them with a copy of the tool for their review, and thus gain the trust of potential buyers.

CTB-Locker

For example, CTB-Locker, a malware program, was first advertised on a Russian underground forum on June 10, 2014 by a user called Tapkin. This ransomware scans the computer for data files, encrypts them with a unique algorithm, and demands a ransom to release them. Tapkin registered on this forum on June 2, 2014, several days before posting the advertisement, and posted a total of five messages to the forum, all on the subject of CTB-Locker. Around this time, a user by the same name posted identical information on other forums.

Tapkin registered to another Russian underground forum on June 13, 2014, and three days later, he advertised the tool on the forum. This was the first and only thread that Tapkin started on this platform, and all of his posts were about this topic.

Tapkin stopped selling CTB-Locker on June 27, but on November 19, 2014, he posted another advertisement, this time for “serious” clients only. Tapkin last advertised the ransomware on a carding forum on December 8, 2014, after registering to this forum the same day.

Thus, in three cases, Tapkin registered to a forum a few days before posting an advertisement for the tool and did not participate in any other forum discussions. As a newly created profile, Tapkin lacked seniority and therefore had low credibility. However, our impression is that this user demonstrates knowledge regarding the tool, its capabilities and can answer questions regarding the technical component of the tool fluently. An analysis of Tapkin’s posts indicates that behind the shell profile is not one person, but rather a group of people who developed the tool together.

This username appears to have been created for the sole purpose of selling the ransomware, which was only advertised on Russian-speaking platforms. On May 19, 2015, a well-known forum user posted a message stating that his computer had been infected by CTB-Locker and asking for Tapkin. However, Tapkin had by then already disappeared.

Loki Bot

Another example of malware advertised by a new forum member is the Loki Bot password and coin wallet stealer. Loki Bot, written in C++, can steal passwords from browsers, FTP/SSH applications, email accounts, and poker clients. It has an option to configure C&C IP addresses or domains.

This bot, which works on Windows versions XP, Vista, 7, 8, and 8.1, is relatively new and is still under development. It was first advertised on a well-known Russian underground forum in early May 2015 by a new user with no reputation. A week later, a user by the same name registered on two other well-known underground forums attempted to boost his credibility by sending the forum administrator a test version of the malware. Similar to the previous example, we assume that a group of people is behind this user as well.

Forum administrator approves a new tool advertised by a “shell profile” user (May 18, 2015)
Forum administrator approves a new tool advertised by a “shell profile” user (May 18, 2015)

We can see that new users are registering on Russian underground forums for one purpose only, to sell a particular malware program, and their entire online presence is focused on this. They register to a forum a few days before posting an advertisement for the tool and do not participate in other forum discussions. Newly created profiles lack seniority and therefore have low credibility ratings. Sometimes such users attempt to improve their credibility by sending the forum administrator a test version of the malware. In some cases we can see that behind the shell profile there is a team, and not an individual. They appear suddenly and disappear just as suddenly after their business is completed.

AnonGhost VS Uncle Sam (#OpUSA – May 7, 2015)

Hacking group AnonGhost has published an official video on #OpUSA, its upcoming cyber campaign against the United States. The video, addressed to the U.S. government, does not mention the date of the campaign or the list of targets, but based on the group’s 2013 #OpUSA campaign, it appears that it is set to take place on May 7. The official video’s YouTube page mentions prominent AnonGhost members Mauritania Attacker, An0nx0xtn, DarkCoder, Donnazmi, and Hussein Haxor, all of whom promote the group’s agenda in social networks.

On May 7, 2013, AnonGhost, along with other groups such as the Tunisian Hackers, threatened to hack American government and financial websites. While they were highly motivated, they failed to achieve much other than to deface several websites and leak emails and personal information. A possible reason for their limited success is that several days before the campaign, hackers speculated on social media that #OpUSA was actually a trap set by the federal government in order to expose and arrest the participants.

One of the groups that participated in 2013, N4m3le55 Cr3w, published a long list of recommended DDoS tools at that time, most of which are common hacking tools that are likely to be used in the current campaign as well.

  • HOIC
  • LOIC
  • Slowloris
  • ByteDos
  • TorsHammer, a Python-based DDoS tool created by the group called An0nSec.
  • SYN Flood DOS, a DDoS tool that operates with NMAP and conducts a SYN Flood attack.

MitM Attacks Pick Up Speed – A Russian Coder Launches a New Web Injection Coding Service

In a successful MitM attack, the hacker infiltrates a web session between a bank and a bank customer, intercepts the messages they are exchanging, including credentials and classified information, and injects new messages, all without arousing the suspicion of either party.

In most cases, the injections are tailored to the victim. In other words, the victim sees a website purporting to belong to the specific bank whose site the victim is attempting to access. The injections are delivered via banking Trojans such as Zeus. On closed forums, injections are sold as separate modules for banking malware.

Web injections are sold on a Russian underground forum

On one of the leading Russian-language cybercrime forums, we recently discovered a new thread offering web-injection services. The author was selling a large variety of injections for banks and online services in the United States and Canada.

According to the thread, the service includes an administration panel for managing the infected machines and stolen data, the ability to change the victim’s banking account balance (after a money transfer was performed), the ability to grab answers to security questions, and many other features.

The prices are quite affordable and vary from $50 to $150, though it should be noted that anyone wishing to carry out an MitM attack should already possess a botnet of machines infected with banking Trojans. When the victim tries to access his bank account, the attacker intercepts the session and displays a fake webpage that is very similar to the real bank’s site. The victim is asked to fill in login credentials, answer security questions, provide credit card data, and more. The attacker immediately receives the information through the administration panel and can use it to transfer the money, while the victim receives a connection error and simply tries to connect to the bank’s website one more time.

Detecting such an attack can be difficult, since one failed connection to the bank website or minor differences between the design of the fake page and that of the real page do not usually arouse the victim’s suspicions. In addition, as mentioned above, the account balance that the victim sees does not change after the money has been stolen.

The seller has launched a website to promote sales of the injections he coded. The site contains samples of injections for banks in the United States and Canada and for online services such as PayPal and Ebay. The targeted banks are Wells Fargo, HSBC, Citizens Bank, Scotiabank, RBC Bank, and many more. There was a section in the site indicating that European institutions will be targeted in the future.

School Is Now in Session – The Spread of Hacking Tutorials in the Deep and Dark Web

One of the most common posts seen on hacker forums is “Hello, I’m new and I want to be a hacker.” Any aspiring hacker must learn coding, networking, system security, and the like, and increasingly, hacking forums are responding to this demand and providing tutorials for those who wish to learn the basics quickly.

Hacking forums have two main kinds of tutorial sections, one open to any forum member and the other exclusively for VIP members. In this post we will review two case studies from closed forums, one from the onion network and the other from the Deep Web.

Case Studies

The first tutorial, taken from a closed forum in the onion network, is actually four tutorials wrapped together to teach POS (point-of-sale) hacking. It includes a list of essential malware and software for POS hacking. While it starts with a basic overview of POS and of RAM (random-access memory) scraping, it very quickly dives into explanations that require an advanced understanding of hacking.

The second tutorial is a basic PayPal hacking tutorial, taken from a closed forum on the Deep Web and oriented toward noobs (beginners). It is actually more about scamming than hacking. It notes that one way to get user details is to hack vulnerable shopping sites using SQL injections and explains how to check whether the stolen user details are associated with a PayPal account. It also mentions that user details can simply be acquired from posts on the forum.

What is really interesting is that this practical forum has many tutorial sections and sub-sections (we counted six), which raises an interesting question: Why do hackers share?

Motives

There is no one answer to this question, but we can divide hackers’ motivations into four categories:

  • Self-promotion – One of the differences between regular hackers and good hackers is reputation. The most obvious way for hackers to improve their reputation is of course to perform a good hack, but they can also enhance their reputation by being part of a well-known hacking team or displaying vast knowledge, such as by publishing tutorials. It appears that Red, a junior member of the onion network forum who is not known and has a small number of posts, is increasing his value in the eyes of other forum members and site administrators by publishing tutorials, including the POS tutorial. This improved reputation can give him new privileges, such as access to the forum’s VIP sections. In most cases, tutorials shared for this reason range from beginner to intermediate level and can be understand by almost any beginner.
  • Site promotion – Commerce in hacking forums hiding deep in the Internet works like any other free market: if you have the right goods, people will come and your business will boom, but if your shop does not look successful, customers will stay away. Hacking forums, like other businesses, compete for the attention of their target audience. The PayPal tutorial was published by BigBoss, a site administrator, who was probably seeking publicity for the site. To ensure that there is a large number of tutorials on the site, the administrators publish their own from time to time. These can be very simple (as in this case) or very specialized and technical (such as those offered in closed forum sections).
  • Financial gain – As we noted, these forums are businesses, and like any business, they need to sell products in order to make a profit. They can do this by creating VIP sections with unique content (such as special tutorials) open to paying members only, as opposed to VIP sections based on reputation or Individual members also use the forums for financial gain and sell more concrete items—malware, credit cards, and the like—or more abstract items, like knowledge in the form of tutorials or lessons. In most cases the tutorials are very advanced, with extensive details, so that their creators can charge for them.

  • Knowledge sharing — Sometimes, people share their knowledge without any ulterior motive. This is usually done in a closed section of a forum and only with prime members or a group of friends. In this case, the knowledge shared varies according to the group and can be state-of-the-art or very simple.

Conclusions

In a society based heavily on information, we cannot escape the frequently rehashed concept that “knowledge is power.” As the technology world continues to evolve and the hacker community along with it, the need for “how to” knowledge is growing. Tutorials provide beginners with an effective gateway into the world of hacking and expose advanced users to new methods of operation. For us, the observers, they provide a small glimpse into developing trends, attack methods, methods of assessing hacker knowledge, and much more.

Australian Banks Targeted by Russian Malware for Android Devices

Introduction

Several months ago, while monitoring Russian underground forums, we came across a new malware designed to attack Android smartphones via a social engineering vector, luring victims into providing their banking data, as well as credit card details to the attackers.

The malware is dubbed GM BOT, and it has been offered for rent since October 2014 on a Russian underground forum dealing with malware development and sales. The price was $4,000 for one month, and this later dropped to $2,000. In January 2015, the renter of the GM BOT posted about deploying the malware on Australian botnet, including screenshots of banking details from Australian banks.

Later, in February 2015, the renter posted examples of Man-in-the-Middle (MitM) attacks that can be carried out by his malware, two of them presenting fake login pages to Australian banks.

GM BOT Capabilities

The first version of the malware was released on October 29, 2014 and according to the thread, it is designed to collect banking and credit card details. The data collection from the infected devices is performed via a social engineering vector, when fake pages are presented to victims. The tool works in different ways:

  • Collection of VBV data by using a fake Google Play application (Luhn algorithm is used for validation).
  • Scanning the mobile phone for installed banking services, and presenting dialog boxes for filling in confidential data.
  • Checking for email and social media accounts linked to the phone (Gmail, Facebook, Twitter, etc.) and presenting dialog boxes for filling in confidential data.

In addition, the malware is capable of incoming SMS message interception and blocking (to avoid alerts from the bank from reaching the victim), as well as incoming call redirection, GPS data monitoring and more. The malware received highly positive feedback from other forum members, as suitable for cybercrime activity.

Initially, the thread’s author specified that the bot would be rented to five clients – Russian speakers only. On November 3, 2014, the renter announced that all the five clients had been found, and that the ad was no longer relevant. However, one month later, on December 2, he posted about updates of GM BOT capabilities, saying that he is looking for more clients. The new version of the bot enables its operator to create JS or HTML dialog boxes that are presented to the victim, thus expanding the number of accounts whose credentials can be achieved.

The Australian Link

On January 13, 2015, the author posted again. This time the post included screenshots showing the results of GM BOT activity. According to the post, 165 users in Australia were infected on January 10. 68 of these were communicating back with the C&C infrastructure at the moment of the post. Screenshots of the collected data were attached.

On February 12, 2015, another post regarding GM BOT was uploaded by the author, focusing on its MitM attacks capabilities. According to this post, the bot can inject JS or HTML code into running application, thus showing the user fake pages for drawing out data.

It should be mentioned that the malware distribution method is not included in the rented product. This means that the attacker who purchases the malware delivers it to the victims by a method of his choosing, spam emails for instance.

Anthem Hack: Is the Healthcare Industry the Next Big Target?

Anthem Inc., the second largest health insurer in the US, has suffered a security breach to its databases. According to media reports, the breached database contains information from approximately 80 million individuals. Although medical records appear not to be in danger, names, birthdays, social security numbers, email addresses, employment information and more have been compromised.

Anthem described the hacking as a “very sophisticated attack,” and the company  reported it to the FBI and even hired a cyber security firm to help with the investigations. However, the extent of the stolen data is still being determined. In addition, there is no concrete information regarding the perpetrators and the modus operandi (MO) of this cyber-attack.

In February 2014 we wrote that cyber criminals are shifting their focus from the financial industry to the healthcare industry, which has become an easier target. Healthcare records contain a wealth of valuable information for criminals, such as social security numbers and personal information. This information can sometimes prove more valuable than credit card numbers, which the financial industry is working hard to protect.

In 2013, at least twice as many individuals were affected by healthcare data breaches than in the previous year, owing to a handful of mega-breaches in the industry. According to a cyber security forecast, published at the end of 2013, the healthcare industry was likely to make the most breach headlines in 2014. However, it appears that 2014 was the year in which American retailers suffered massive data breaches (Home Deopt, Staples, Kmart, and of course Target at the end of 2013).

We should consider the Anthem hack as a warning sign for all of us – the healthcare industry might be the prime target for cyber criminals in 2015. We already know that PPI (Personally Identifiable Information) and PHI (Protected Health Information) sales on black markets continue to rise. Such underground marketplaces are being used as a one-stop shop for identity theft and fraud. Such breaches can cost their victims dearly – putting their health coverage at risk, causing legal problems or leading to inaccurate medical records. Here at SenseCy, we monitor on a daily basis the usage of breached medical information on Underground forums and the Darknet platforms.

We believe that this industry is facing major threats from cyberspace. These threats encompass large areas of the industry and may become a greater burden for it, compromising patient safety, and causing financial and commercial damage to the associated bodies.

SenseCy 2014 Annual Cyber Intelligence Report

Written and prepared by SenseCy’s Cyber Intelligence analysts.

Executive Summary

Clearly, 2014 was an important year in the cyber arena. The technical level of the attacks, the variety of tools and methods used and the destructive results achieved have proven, yet again, that cyber is a cross-border tool that is rapidly gaining momentum.

This year, we witnessed attacks on key vectors: cyber criminals setting their sights on targets in the private sector, hacktivists using cyber tools for their ideological struggles, state-sponsored campaigns to facilitate spying on high-profile targets, and cyber conflicts between countries.

The following is an excerpt from an annual report prepared by our Cyber Intelligence analysts. To receive a copy, please send a request to: info@sensecy.com

Insights

Below are several of our insights regarding cyber activity this past year:

  • The financial sector was and continues to be a key target for cyber criminals, with most of the corporations hacked this year in the U.S. being attacked through infection of Point-of-Sale (POS) systems. Despite the high level of awareness as to the vulnerability of these systems following the Target breach at the end of 2013, ever more organizations are continuing to fall victim to these types of attacks, as the cybercrime community develops and sells dedicated tools for these systems.
  • In 2014, we saw another step up in the use of cyber as a cross-border weapon, the use of which can be highly destructive. This was evidenced in the attack on JPMorgan, which according to reports was a response to sanctions imposed by the U.S. on Russia. The ensuing Sony breach and threats to peoples’ lives should the movie The Interview be screened exacerbated the state of asymmetrical war in cyber space, where on the one hand, we see countries attacking companies, and on the other, groups of hackers attacking countries. This trend becomes even more concerning following the reports of the deaths of three workers at a nuclear reactor in South Korea, after it became the target of a targeted cyber-attack, evidently by North Korean entities.
  • This past year was rife with campaigns by anti-Israel hacktivist campaigns, whose motivation for attacking Israel’s cyber networks was especially strong. Again, it was clearly demonstrated that the relationship between physical and virtual space is particularly strong, when alongside Operation Protective Edge (July-August 2014), we witnessed a targeted cyber campaign by hacktivist organizations from throughout the Muslim world (but not only) and by cyber terror groups, which in some cases were able to score significant successes. We believe that in 2015, attacks by hacktivist groups will become higher quality (DDoS attacks at high bandwidth, for example) and the use of vectors, which to date have been less common, such as attacks against mobile devices, will become increasingly frequent.
  • Involvement of the internal factor in cyber-attacks: According to some speculations published recently in the global media regarding the massive Sony breach, former company employees  may have abused their positions and status to steal confidential information and try to harm the organization. This underscores the importance of information security and internal compartmentalization in organizations with databases containing sensitive information.

The Past Year on the Russian Underground

In 2014, we saw active underground trading of malware and exploits, with some of them being used in attacks inside and outside Russia that gained widespread media coverage in sources dealing with information security.

The following is a list of categories of malware and the main services offered for sale in 2014 on the Russian-speaking underground forums. Note that in this analysis, we only included important tools that were well-received by the buyers, which indicates their reliability and level of professionalism. Additionally, only tools that were sold for over a month were included. Let us also note that the analysis does not include special PoS firmware, but only programs designed to facilitate remote information theft through takeover of the terminal.

Prices

The average price of a tool offered for sale in 2014 was $1,500. Since 2013, the average price has increased by $500. The following graph lists the average price in each of the categories outlined above (in USD):

Key Trends Observed on the Russian Underground this Past Year

Trojan Horses for the Financial Sector

Malware designed to target financial institutions is a highly sought-after product on the Russian underground, and this past year we observed the development of malware based on Kronos source code – Zeus, Chthonic (called Udacha by the seller) and Dyre malware. Additionally, the sale of tools designed to sell login details for banking sites via mobile devices were also observed.

In this context, it should be noted that the modular structure of many types of financial malware allows flexibility by both the seller and the buyer. Most financial malware is sold in this format – meaning, various modules responsible for the malware’s activity can be purchased separately: Formgrabber module, Web-Injections module and more.

MitM Attacks

This type of attack vector, known to cyber criminals as Web injections, is most common as a module in Trojan horses for the financial sector. Members of many forums offer their services as injection writers, referring to creation of malware designed to be integrated into a specific banking Trojan horse (generally based on Zeus), tailored to the specific bank, which imitates the design of its windows, etc. In 2014, we saw this field prosper, with at least seven similar services offered on the various forums.

Ransomware

This year we witnessed a not insignificant amount of ransomware for sale on Russian-speaking forums. It would appear that the forums see a strong potential for profit through this attack vector and therefore invest in the development of ransomware. Furthermore, note that some of the ransomware uses the Tor network to better conceal the command and control servers. Since CryptoLocker was discovered in September 2013, we have seen numerous attempts at developing similar malware both for PCs and laptops.

Additional trends and insights are detailed in the full report.
