Win32/GenKryptik.GNNJ Summary

In summary, Win32/GenKryptik.GNNJ ransomware actions in the infected computer are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Reads data out of its own binary image;
  • CAPE extracted potentially suspicious content;
  • Drops a binary and executes it;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;

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 used in Win32/GenKryptik.GNNJ (typically, 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. However, that virus does not do all these terrible things without delay – it can take up to several hours to cipher all of your documents. Therefore, seeing the Win32/GenKryptik.GNNJ detection is a clear signal that you must start the removal procedure.

Where did I get the Win32/GenKryptik.GNNJ?

Common tactics of Win32/GenKryptik.GNNJ distribution are basic for all other ransomware examples. Those are one-day landing websites where users are offered to download the free software, so-called bait emails and hacktools. Bait e-mails are a relatively new method in malware spreading – you get the email that mimics some standard notifications about deliveries or bank service conditions modifications. Within 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 simple, however, still requires tons of focus. Malware can hide in various places, and it is far better to stop it even before it gets into your PC than to rely on an anti-malware program. Common cybersecurity awareness is just an important thing in the modern-day world, even if your relationship with a PC stays on YouTube videos. That may keep you a lot of money and time which you would spend while seeking a fix guide.
