MSIL/Kryptik.AIYK detection is a virus detection you can spectate in your system. It often shows up after the provoking actions on your PC – opening the untrustworthy email, clicking the advertisement in the Internet or mounting the program from dubious resources. From the second it shows up, you have a short time to do something about it before it begins its malicious activity. And be sure – it is better not to await these harmful effects.

What is MSIL/Kryptik.AIYK virus?

MSIL/Kryptik.AIYK is ransomware-type malware. It searches for the files on your disks, ciphers it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your documents inaccessible, this malware additionally does a lot of harm to your system. It alters the networking setups in order to avoid you from checking out the elimination guidelines or downloading the anti-malware program. In some cases, MSIL/Kryptik.AIYK can also prevent the launching of anti-malware programs.

MSIL/Kryptik.AIYK Summary

In summary, MSIL/Kryptik.AIYK virus activities in the infected PC are next:

  • Sample contains Overlay data;
  • Reads data out of its own binary image;
  • CAPE extracted potentially suspicious content;
  • Drops a binary and executes it;
  • The binary contains an unknown PE section name indicative of packing;
  • Authenticode signature is invalid;
  • Yara detections observed in process dumps, payloads or dropped files;
  • Encrypting the documents kept on the target’s drives — so the victim cannot open these files;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-virus programs

Ransomware has been a horror story for the last 4 years. It is challenging to realize a more damaging malware for both individual users and corporations. The algorithms utilized in MSIL/Kryptik.AIYK (usually, 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 already exists, and possibly will exist. But that malware does not do all these terrible things instantly – it may take up to a few hours to cipher all of your files. Thus, seeing the MSIL/Kryptik.AIYK detection is a clear signal that you have to begin the clearing procedure.

Where did I get the MSIL/Kryptik.AIYK?

Usual tactics of MSIL/Kryptik.AIYK distribution are typical 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 e-mails and hacktools. Bait e-mails are a pretty new method in malware distribution – you receive the email that mimics some routine notifications about deliveries or bank service conditions changes. Within the e-mail, there is an infected MS Office file, or a web link which leads to the exploit landing site.

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 various places, and it is far better to stop it even before it invades your PC than to rely on an anti-malware program. Common cybersecurity knowledge is just an essential item in the modern-day world, even if your relationship with a computer remains on YouTube videos. That can save you a lot of money and time which you would certainly spend while trying to find a fixing guide.
