MSIL/Agent.BLN detection is a virus detection you can spectate in your system. It generally appears after the preliminary procedures on your PC – opening the dubious email, clicking the advertisement in the Internet or mounting the program from untrustworthy sources. From the second it shows up, you have a short time to do something about it until it starts its malicious action. And be sure – it is better not to await these destructive actions.

What is MSIL/Agent.BLN virus?

MSIL/Agent.BLN is ransomware-type malware. It searches for the documents on your disk, ciphers it, and then asks you to pay the ransom for receiving the decryption key. Besides making your files inaccessible, this virus additionally does a ton of damage to your system. It changes the networking settings in order to prevent you from looking for the removal articles or downloading the anti-malware program. Sometimes, MSIL/Agent.BLN can also block the launching of anti-malware programs.

MSIL/Agent.BLN Summary

In total, MSIL/Agent.BLN ransomware actions in the infected computer are next:

  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Behavioural detection: Executable code extraction – unpacking;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Creates RWX memory;
  • Guard pages use detected – possible anti-debugging.;
  • Dynamic (imported) function loading detected;
  • Starts servers listening on,;
  • CAPE extracted potentially suspicious content;
  • Authenticode signature is invalid;
  • Encrypting the files located on the victim’s drives — so the victim cannot use 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 horror story for the last 4 years. It is challenging to realize a more hazardous virus for both individual users and businesses. The algorithms used in MSIL/Agent.BLN (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need more time than our galaxy actually exists, and possibly will exist. But that malware does not do all these unpleasant things without delay – it may take up to a few hours to cipher all of your files. Hence, seeing the MSIL/Agent.BLN detection is a clear signal that you should begin the clearing process.

Where did I get the MSIL/Agent.BLN?

Common ways of MSIL/Agent.BLN spreading are basic for all other ransomware examples. Those are one-day landing websites where victims are offered to download the free app, so-called bait e-mails and hacktools. Bait e-mails are a pretty modern method in malware spreading – you receive the email that imitates some regular notifications about deliveries or bank service conditions shifts. Inside of the e-mail, there is a corrupted 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 quite easy, but still needs a lot of attention. Malware can hide in different places, and it is much better to stop it even before it gets into your system than to rely on an anti-malware program. Simple cybersecurity awareness is just an essential item in the modern world, even if your interaction with a PC stays on YouTube videos. That may save you a great deal of money and time which you would certainly spend while trying to find a fixing guide.
