What is the Win32:Evo-gen [Trj] virus?

The Win32:Evo-gen [Trj] is a type of ransomware that searches for documents on your disk drive, encrypts them, and then demands a ransom in exchange for the decryption key. In addition to locking your files, this malware also inflicts significant damage to your system.

Win32:Evo-gen [Trj] Summary

In summary, Win32:Evo-gen [Trj] ransomware actions in the infected computer are next:

  • Executed a command line with /C or /R argument to terminate command shell on completion which can be used to hide execution;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • CAPE extracted potentially suspicious content;
  • The binary contains an unknown PE section name indicative of packing;
  • Authenticode signature is invalid;
  • Uses Windows utilities for basic functionality;
  • Behavioural detection: Injection (inter-process);
  • Behavioural detection: Injection with CreateRemoteThread in a remote process;
  • CAPE detected the Zeppelin malware family;
  • Deletes executed files from disk;
  • Uses suspicious command line tools or Windows utilities;
  • Encrypting the files located on the target’s drives — so the victim cannot open these documents;
  • Blocking the launching of .exe files of anti-virus apps
  • Blocking the launching of installation files of anti-malware apps

Ransomware has actually been a headache for the last 4 years. It is hard to imagine a more damaging virus for both individuals and organizations. The algorithms used in Win32:Evo-gen [Trj] (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need a lot more time than our galaxy already exists, and possibly will exist. But that virus does not do all these horrible things without delay – it can require up to a few hours to cipher all of your files. Thus, seeing the Win32:Evo-gen [Trj] detection is a clear signal that you need to start the elimination procedure.

Where did I get the Win32:Evo-gen [Trj]?

Standard ways of Win32:Evo-gen [Trj] spreading are common for all other ransomware variants. Those are one-day landing web pages where victims are offered to download and install the free app, so-called bait e-mails and hacktools. Bait emails are a relatively new method in malware spreading – you receive the email that imitates some regular notifications about shipments or bank service conditions updates. Within the e-mail, there is an infected MS Office file, or a link which opens the exploit landing page.

Malicious email spam

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

Preventing it looks quite uncomplicated, but still demands a lot of focus. Malware can hide in different places, and it is much better to stop it even before it invades your system than to rely on an anti-malware program. Standard cybersecurity awareness is just an important thing in the modern world, even if your relationship with a computer remains on YouTube videos. That may save you a great deal of money and time which you would certainly spend while seeking a solution.
