Various techniques may be utilized for the spread of .jimm files virus. However, the main one is considered to be malspam. By launching massive spam email campaigns hackers are able to reach online users around the globe and eventually trick them into running malicious code on their devices. Emails that aim to deliver malware often pose as representatives of legitimate websites, services, and even governmental institutions.

As of the presence of malicious code, it could be recognized by the existence of a file attachment presented as a document, invoice, bill, purchase receipt, banking document, etc. Since this file could contain the payload of .jimm cryptovirus, it triggers the attack as soon as it is run on the operating system.

Another malicious element that may appear in these malicious emails is a URL address being it in the form of an in-text link, button, coupon, banner, image or other clickable forms. The load of the page behind this URL address again results in the unnoticed execution of ransomware payload.

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

These files support the contamination of predefined system processes and components’ settings. Since most of the affected processes and components are essential for the regular system regular performance, it is highly recommendable to consider the removal of all malicious files and objects associated with Snatch .jimm ransomware as soon as possible. Furthermore, it is good to properly secure your system against other malware threats.

The Windows Registry Editor is also likely to be infected by this ransomware. So if you want to prevent it from loading automatically every time you start the operating system, you need to open the Editor and search for Run and RunOnce registry keys. And in case you find malicious values listed under these keys you should remove them.

One reason for .jimm files virus to misuse the RunOnce registry key is the necessity to display its ransom message on the screen. This actually is the final attack stage.

Here is what the text stored in .jimm cryptovirs’ ransom note Restore_JIMM_Files.txt reads:

Do not rename the ciphered files
Do not try to decrypt your data with the help of the third-party software, it can cause constant data loss
If you, your programmers or your friends help you to decrypt your files – it can lead to data loss
You do not joke with files.
My email [email protected]
