.RekenSom Virus (.RekenSom Ransomware) Removal and Recovery

The .RekenSom virus is a ransomware that is currently set against target end users on a global scale. There is no information available about the hacking group behind it. It is believed to be a new iteration of the famous ransomware family. This is one of the reasons why we believe that the hackers are experienced.

Once the .RekenSom virus has started it will execute its built-in sequence of dangerous commands. Depending on local conditions or the specific hacker instructions various actions will take place. The file encryption will begin after them — the encrypting component will use a built-in list of target file type extensions. In the end the victim files will be renamed with the .RekenSom extension.

Threat Summary

Data Recovery Tool	Windows Data Recovery by Stellar Phoenix Notice! This product scans your drive sectors to recover lost files and it may not recover 100% of the encrypted files, but only few of them, depending on the situation and whether or not you have reformatted your drive.

The .RekenSom virus if a a file encrypting ransomware which has recently been detected in a limited attack campaign. The threat does not appear to be particularly widespread among the intended victims. It is possible that the threat is still under development or being tested against only against certain types of victims.

As information about it is still very limited we anticipate that the hackers are going to use popular infection methods which are relatively easy to launch against large groups of computer users. An example of this is the creation of macro-infected documents which are created in the most popular file formats: presentations, text documents, databases and spreadsheets. The other popular malware carrier which is often created by hackers is the infected setup bundle — these are installers of popular software which include popular programs which are frequently downloaded and installed by end users. These files can be easily spread over phishing emails and sites that are created as part of the distribution campaign. They are commonly hosted on sites that sound very similar to the ones which are impersonated. Furthermore they can be uploaded to file-sharing networks where commonly pirate and legitimate files are frequently found. Victims can also get infected by running dangerous web scripts or downloading and installing malware browser extensions. These threats can be downloaded from different Internet sources or deployed by other existing malware infections.

What we know about the .RekenSom virus is that it will start infection right after it has been installed on a given computer. It includes code sources from several smaller ransomware families showing that the hacking group behind it has integrated the potential of other threats. It is very possible that the installation sequence of the threat will start as soon as the threat infects the target device.

There are several processes associated with the .RekenSom virus that are created by the main engine. This means that the threat can be configured to interact with the operating system and its processes. Depending on the individual configuration of the samples this might mean that the malware can hijack user input and system data, possibly indicating potential theft of sensitive information. By hooking up to existing programs and services the .RekenSom virus can also stop running processes. This can result in the running of a security bypass option — the virus may stop any running programs that can potentially block the virus and alert of its presence: anti-virus programs, firewalls, sandbox environments and etc.

At any time the main virus engine can also add in new modules. When all intended actions have run properly the actual file encryption will start. The virus analysis of one of the samples shows the file extensions which are targeted. They will be processed by a very strong cipher and made inaccessible to the users:

A distinction from other similar threats is that the current versions do not create a ransom note file. Instead the hackers can configure various types of lockscreen instances. All of the affected files will receive the relevant .RekenSom extension.

Process control is also a very important feature of this virus — the main ransomware engine can spawn a lot of processes with the intention of making it very hard to stop the running infection. It can also hookup to running apps and services which means that the main engine can hijack the user input and entered data. This is related to an information gathering operation through which the virus can gather sensitive personal data which can be used for crimes such as identity theft and financial abuse.

The main engine is capable of modifying and deleting user data — this can include user data, important system files and backups. What is more dangerous is that the engine can interact with the Windows Mount Manager — this will allow the virus to interact with removable storage devices, network shares and etc.

A basic Trojan module may also be enabled as part of some of the infections — it will gather all harvested information and send it to the criminals via a network connection.

The main ransomware engine will be started as soon as all prior modules have finished running. It will encrypt files with a strong cipher and render them locked — the victims will be manipulated into paying the hackers a fee. The .RekenSom extension will be used to mark the affected files. A ransomware note called HELP_ME_RECOVER_MY_FILES.txt will be created and will contain the hacker instructions.

The usually targeted registries of Windows machines are the following:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

You can access them by opening the Windows registry editor and deleting any values, created by .RekenSom Virus there. This can happen by following the steps underneath:
