What is MSIL/TrojanDownloader.Agent.PYG virus?

MSIL/TrojanDownloader.Agent.PYG is ransomware-type malware. It searches for the documents on your disks, ciphers it, and after that asks you to pay the ransom for getting the decryption key.

MSIL/TrojanDownloader.Agent.PYG Summary

Summarizingly, MSIL/TrojanDownloader.Agent.PYG virus actions in the infected computer are next:

  • CAPE extracted potentially suspicious content;
  • .NET file is packed/obfuscated with SmartAssembly;
  • Authenticode signature is invalid;
  • Binary file triggered multiple YARA rules;
  • Ciphering the documents kept on the victim’s disk drives — so the victim cannot open these files;
  • Blocking the launching of .exe files of anti-malware apps
  • Blocking the launching of installation files of security tools

Ransomware has been a major problem for the last 4 years. It is hard to realize a more dangerous virus for both individuals and organizations. The algorithms utilized in MSIL/TrojanDownloader.Agent.PYG (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have a lot more time than our galaxy already exists, and possibly will exist. However, that malware does not do all these unpleasant things without delay – it can require up to several hours to cipher all of your documents.

Where did I get the MSIL/TrojanDownloader.Agent.PYG?

Typical tactics of MSIL/TrojanDownloader.Agent.PYG spreading are usual for all other ransomware examples. Those are one-day landing web pages where victims are offered to download the free program, so-called bait emails and hacktools. Bait emails are a quite modern tactic in malware distribution – you get the email that simulates some routine notifications about deliveries or bank service conditions updates. Inside of the email, there is a malicious MS Office file, or a web link which opens the exploit landing site.

Malicious email spam

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

Preventing it looks pretty simple, but still demands tons of awareness. Malware can hide in different places, and it is better to prevent it even before it gets into your PC than to rely upon an anti-malware program. Essential cybersecurity awareness is just an important thing in the modern world, even if your interaction with a computer stays on YouTube videos. That may keep you a great deal of time and money which you would spend while looking for a fix guide.
