.risk Files Virus – Distribution

Hackers who stands behind the launch of this devastating threat are likely to use at least one of the most commonly used spread channels.

One way to deliver .risk files virus to users’ devices is definitely malspam. Malspam is technique that enables hackers to spread malicious software via spam email campaigns. And there are several specific traits of these emails. The first one is spoofed email address, sender or both. These emails are often designed to present the names of representatives of well-known companies in order to look trustworthy and eventually trick you into installing the ransomware on your device. Another trait that should always warn you that something may get wrong is the presence of file attachment. There are many registered cases of infected users who had made the mistake to open a malicious file attachment on their devices which resulted in the activation of malicious code. The last trait of an email that attempts to deliver ransomware is URL address presented as an in-text link, button, image, banner or other clickable element.

In fact, URLs that land on infected web pages could be spread across other channels except email. Among them are different social media platforms, forums, and sometimes comments under articles. As a result of visiting such a page you unnoticeably activate a malicious script that is part of its code and eventually grant the ransomware access to your device.

.risk Files Virus – Overview

The ransomware dubbed .risk files virus infects computer systems in order to reach target types of files and encode them with the help of sophisticated cipher algorithm. It has been identified as another strain of the infamous Dharma ransomware. Recently lots of iterations of the same ransomware family have been detected in the wild.

As its predecessors the .risk variant of Dharma ransomware interferes with system settings in order to become able to complete the attack. It passes through several infection stages fist of which is the establishment of malicious files on the system. For it the ransomware could be either set to create needed files directly on the system or to connect its command and control server and download the additional malicious files. Folder locations that may be used for the storage of these malicious files are:

  • %AppData%
  • %Local%
  • %LocalLow%
  • %Roaming%
  • %Temp%
  • %Windows%

Malicious traits could be also found under the registry sub-keys Run and RunOnce. The most common reason why these two keys are often hit by ransomware is their functionality to auto execute files and processes. Once .risk crypto virus manages to add its malicious values under these keys its infection files load together with all other essential system files on each system start. Here are the exact locations of Run and RunOnce sub-keys:

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

When .risk files virus completes all initial system modifications its’s time for it to load its built-in encryption module and eventually encode target data. Among the files it is set to corrupt could be all of the following:

  • Audio files
  • Video files
  • Document files
  • Image files
  • Backup files
  • Banking credentials, etc

During encryption, .risk ransomware transforms the original code of target files with the help of strong cipher algorithm such as AES and RSA. Then it marks each corrupted file with the extension .risk. Unfortunately, all .risk files remain inaccessible until an efficient recovery method reverts back their code. This fact enables threat actors to extort a ransom payment from you. How they do this is via ransom message created on your device. The text of this message is likely to force you into contacting hackers so they can send you further instructions of the ransom payment. What they could want is an amount from 0.1 to 1.0 Bitcoin.

The good news is that hackers’ decrypter is not the only tool that could restore .risk files. To find more alternatives complete the removal process and check the restore data part of the guide that follows.
