What is MSIL/Kryptik.ADRR virus?

MSIL/Kryptik.ADRR is ransomware-type malware. It looks for the documents on your disks, ciphers it, and then asks you to pay the ransom for receiving the decryption key. Besides making your files locked, this virus additionally does a ton of damage to your system.

MSIL/Kryptik.ADRR Summary

Summarizingly, MSIL/Kryptik.ADRR ransomware activities in the infected computer are next:

  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Dynamic (imported) function loading detected;
  • CAPE extracted potentially suspicious content;
  • Authenticode signature is invalid;
  • Ciphering the files kept on the target’s disks — so the victim cannot check these files;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-virus apps

Ransomware has actually been a major problem for the last 4 years. It is challenging to realize a more hazardous malware for both individual users and corporations. The algorithms utilized in MSIL/Kryptik.ADRR (generally, 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 already exists, and possibly will exist. But that malware does not do all these bad things without delay – it can require up to a few hours to cipher all of your files. Hence, seeing the MSIL/Kryptik.ADRR detection is a clear signal that you have to start the elimination procedure.

Where did I get the MSIL/Kryptik.ADRR?

Typical ways of MSIL/Kryptik.ADRR injection are usual for all other ransomware variants. Those are one-day landing web pages where users are offered to download the free software, so-called bait emails and hacktools. Bait e-mails are a pretty modern tactic in malware distribution – you receive the e-mail that mimics some normal 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 site.

Malicious email spam

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

Avoiding it looks fairly simple, however, still needs tons of recognition. Malware can hide in various places, and it is much better to stop it even before it goes into your computer than to trust in an anti-malware program. Standard cybersecurity knowledge is just an important item in the modern-day world, even if your interaction with a PC stays on YouTube videos. That can keep you a great deal of time and money which you would spend while looking for a solution.
