What is Trojan:MSIL/Polyransom!atmn virus?

Trojan:MSIL/Polyransom!atmn is ransomware-type malware. It searches for the files on your computer, ciphers it, and after that asks you to pay the ransom for receiving the decryption key.

Trojan:MSIL/Polyransom!atmn Summary

Summarizingly, Trojan:MSIL/Polyransom!atmn virus activities in the infected system are next:

  • Authenticode signature is invalid;
  • Ciphering the files located on the victim’s drive — so the victim cannot check these files;
  • Blocking the launching of .exe files of anti-malware programs
  • Blocking the launching of installation files of security tools

Ransomware has actually been a headache for the last 4 years. It is difficult to realize a more damaging malware for both individuals and businesses. The algorithms utilized in Trojan:MSIL/Polyransom!atmn (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 actually exists, and possibly will exist. But that malware does not do all these horrible things immediately – it can require up to a few hours to cipher all of your files. Hence, seeing the Trojan:MSIL/Polyransom!atmn detection is a clear signal that you have to start the clearing procedure.

Where did I get the Trojan:MSIL/Polyransom!atmn?

Usual methods of Trojan:MSIL/Polyransom!atmn spreading are common for all other ransomware variants. Those are one-day landing websites where victims are offered to download and install the free program, so-called bait emails and hacktools. Bait emails are a quite new method in malware spreading – you receive the email that mimics some routine notifications about shipments or bank service conditions changes. Within the e-mail, 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 pretty simple, but still demands tons of recognition. Malware can hide in various places, and it is far better to stop it even before it goes into your system than to rely upon an anti-malware program. Simple cybersecurity awareness is just an important thing in the modern world, even if your interaction with a PC remains on YouTube videos. That may keep you a lot of money and time which you would spend while seeking a solution.
