MSIL/GenKryptik.EPUP detection is a virus detection you can spectate in your computer. It usually appears after the preliminary actions on your PC – opening the dubious email messages, clicking the advertisement in the Internet or setting up the program from suspicious sources. From the moment it shows up, you have a short time to act until it starts its harmful activity. And be sure – it is much better not to wait for these harmful things.

What is MSIL/GenKryptik.EPUP virus?

MSIL/GenKryptik.EPUP is ransomware-type malware. It looks for the files on your disk drive, ciphers it, and then asks you to pay the ransom for getting the decryption key. Besides making your files inaccessible, this malware also does a ton of damage to your system. It modifies the networking settings in order to avoid you from looking for the removal guidelines or downloading the anti-malware program. In some cases, MSIL/GenKryptik.EPUP can also stop the launching of anti-malware programs.

MSIL/GenKryptik.EPUP Summary

Summarizingly, MSIL/GenKryptik.EPUP malware actions in the infected system are next:

  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Creates RWX memory;
  • Guard pages use detected – possible anti-debugging.;
  • Dynamic (imported) function loading detected;
  • CAPE extracted potentially suspicious content;
  • .NET file is packed/obfuscated with Confuser;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Anomalous .NET characteristics;
  • Encrypting the documents located on the victim’s disk drive — so the victim cannot use these documents;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-malware programs

Ransomware has actually been a nightmare for the last 4 years. It is hard to picture a more damaging virus for both individual users and organizations. The algorithms utilized in MSIL/GenKryptik.EPUP (typically, 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 actually 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 documents. Therefore, seeing the MSIL/GenKryptik.EPUP detection is a clear signal that you should begin the removal process.

Where did I get the MSIL/GenKryptik.EPUP?

Standard tactics of MSIL/GenKryptik.EPUP distribution are standard for all other ransomware variants. Those are one-day landing web pages where victims are offered to download and install the free program, so-called bait e-mails and hacktools. Bait e-mails are a pretty modern strategy in malware distribution – you receive the e-mail that mimics some standard notifications about shipments or bank service conditions updates. Inside of the e-mail, there is an infected 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.

Preventing it looks quite uncomplicated, however, still needs tons of awareness. Malware can hide in different places, and it is much better to stop it even before it goes into your PC than to trust in an anti-malware program. Common cybersecurity awareness is just an essential thing in the modern-day world, even if your relationship with a PC stays on YouTube videos. That can keep you a great deal of time and money which you would certainly spend while searching for a solution.
