RetMyData Ransomware – Distribution Techniques

The RetMyData ransomware is a new virus threat which appears to be of original origins, it does not correspond to any of the known malware families and targets English-speaking users from around the world. The available research shows that the released samples might include test versions as well. For this reason the criminals behind the threat might be using several strategies in order to discover which one would be the most appropriate.

One of them is the coordination of email SPAM campaigns which depend on phishing tactics that attempt to coerce the victims into believing that they have received a legitimate message from a well-known service, product or company. The messages will be designed in a way which will seem familiar, if cross-referenced information about the victims is extracted the phishing messages will include it as well. The RetMyData ransomware file can be delivered directly as attachments or linked in the body contents through interactive elements such as links, multimedia content or scripts.

Another similar technique is the creation of fake web sites which may impersonate vendor landing pages or download portals. They are made by using similar-sounding domain names and design elements which can confuse even experienced computer users. As soon as they are accessed they can directly offer the RetMyData ransommware files or redirect to them.

File-sharing networks like BitTorrent are particularly effective at spreading ransomware like this as they are used to share both legitimate installers and pirate content.
These delivery mechanisms can also make use of payload carriers, there are two popular types which are exhibited by virus infections:

  • Software Setup Files — The criminals can take the legitimate installers of popular applications and embed the malicious scripts in them. Examples include productivity apps, office suites, creativity programs, utilities and games.
  • Infected Documents — All popular document files can become the victim of RetMyData ransomware code: presentations, databases, text documents and spreadsheets. When they are opened by the victims a prompt will appear asking for the built-in macros to be run in order to “view” the files. If this is done the virus installation will commence.

RetMyData ransomware files may also be spread using browser hijackers which are malicious extensions made for most web browsers. They are often uploaded to the relevant repositories with fake user and developer credentials promising many feature additions or performance optimizations. If installed they will change settings such as the default home page, search engine and new tabs page. Coupled with the redirect to a hacker-controlled landing page the RetMyData ransomware will also be deployed.

Other delivery methods can also be considered depending on the success of the released samples.

RetMyData Ransomware – Detailed Analysis

The RetMyData ransomware as mentioned earlier does not originate from any of the famous malware families making it a dangerous threat to all machine owners as its signatures can deviate from the common signatures. It is very possible that the threat is developed by the same group or hacker responsible for its distribution. The other possibility is that the malware has been bought from an underground hacker market by custom order.

The made security analysis on the captured samples reveals that the samples do contain several modules that are launched in the prescribed order. One of them is the data harvesting engine which has been found to extract information contained in the web browsers. The RetMyData ransomware is configured to extract sensitive information about the Internet usage and the victims by downloading the cached cookies, history, settings and any entered account credentials. This mechanism can be updated further to include other potentially useful data such as hardware metrics, user settings and environment values. The extracted information can be used to carry out crimes such as identity theft and financial abuse.

Another dangerous action done by the virus is the extraction of terminal service related keys which are used to carry out remote access sessions. If any such configuration has been made on the infected computers the hackers will be able to use it and login to the hosts.

It is confirmed that the RetMyData ransomware is able to create its own processes, including child ones and also hook up to already running ones. This allows it to extract information from the running programs creating the possibility to spy on the victims activities. The acquired information is then remotely transmitted to the malicious operators. It has been confirmed that regional preferences are also extracted which is useful to the attackers — they can find from which countries the most victims are made and fine tune updated releases to increase the number of infected hosts.

Properly configured virus samples can establish a Trojan horse infection which will make a secure connection to a hacker-controlled server. It allows the operators to spy on the users, access all retrieved data, overtake control of the machines and also deploy other threats.

We have received confirmation that the engine used by the RetMyData ransomware is also capable of accessing and modifying the Windows Registry. Changes to strings that belong to the operating system may render certain services inaccessible and cause serious performance issues. On the other hand modifications of values used by third-party applications can make them impossible to start or with unexpected behavior.

This module can additionally be used to install the RetMyData ransomware in a way which makes it very hard to remove using manual user recovery guides and tools. The reason for this is the reconfiguration of the system: configuration files, boot options and user settings.

RetMyData Ransomware – Encryption Process

The RetMyData ransomware exhibits typical ransomware behavior by using a built-in list of target file type extensions. A strong cipher is employed in order to make data recovery very difficult. Depending on the exact configuration the list may be built into the samples or downloaded upon connection to the hacker-controlled servers.

In most cases the typical lists will target the most commonly used data:

  • Archives
  • Databases
  • Backups
  • Music
  • Videos
  • Photos

All affected files will be encrypted with the .aes256 or .aes256.testE extensions.

Remove RetMyData Ransomware and Try to Restore Data

If your computer system got infected with the RetMyData ransomware virus, you should have a bit of experience in removing malware. You should get rid of this ransomware as quickly as possible before it can have the chance to spread further and infect other computers. You should remove the ransomware and follow the step-by-step instructions guide provided below.
