What is VirTool:MSIL/CryptInject.CG!MTB virus?

VirTool:MSIL/CryptInject.CG!MTB is ransomware-type malware. It searches for the files on your disk, encrypts it, and then asks you to pay the ransom for receiving the decryption key. Besides making your files locked, this malware also does a lot of damage to your system. It modifies the networking settings in order to avoid you from looking for the removal tutorials or downloading the anti-malware program. Sometimes, VirTool:MSIL/CryptInject.CG!MTB can also prevent the launching of anti-malware programs.

VirTool:MSIL/CryptInject.CG!MTB Summary

In total, VirTool:MSIL/CryptInject.CG!MTB ransomware activities in the infected system are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • A file was accessed within the Public folder.;
  • Executed a command line with /C or /R argument to terminate command shell on completion which can be used to hide execution;
  • Sample contains Overlay data;
  • Uses Windows utilities for basic functionality;
  • Reads data out of its own binary image;
  • CAPE extracted potentially suspicious content;
  • Drops a binary and executes it;
  • Authenticode signature is invalid;
  • Behavioural detection: Injection (Process Hollowing);
  • Behavioural detection: Injection (inter-process);
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;

  • Blocking the launching of .exe files of anti-malware programs
  • Blocking the launching of installation files of anti-virus programs

Ransomware has actually been a major problem for the last 4 years. It is challenging to picture a more damaging malware for both individuals and organizations. The algorithms utilized in VirTool:MSIL/CryptInject.CG!MTB (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have more time than our galaxy currently exists, and possibly will exist. But that virus does not do all these unpleasant things immediately – it may require up to a few hours to cipher all of your files. Thus, seeing the VirTool:MSIL/CryptInject.CG!MTB detection is a clear signal that you should begin the clearing procedure.

Where did I get the VirTool:MSIL/CryptInject.CG!MTB?

Typical methods of VirTool:MSIL/CryptInject.CG!MTB spreading are typical for all other ransomware variants. Those are one-day landing websites where users are offered to download and install the free software, so-called bait emails and hacktools. Bait emails are a pretty modern strategy in malware distribution – you get the e-mail that imitates some standard notifications about shippings or bank service conditions shifts. Within the email, there is a corrupted MS Office file, or a web link which opens the exploit landing page.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Avoiding it looks fairly simple, but still requires tons of focus. Malware can hide in different places, and it is much better to stop it even before it goes into your system than to rely upon an anti-malware program. Basic cybersecurity awareness is just an important thing in the modern-day world, even if your interaction with a computer stays on YouTube videos. That can save you a great deal of time and money which you would spend while searching for a solution.
