It often shows up after the provoking activities on your PC – opening the dubious e-mail messages, clicking the advertisement in the Internet or mounting the program from suspicious sources.

What is Win32/GenKryptik.FZWW virus?

Win32/GenKryptik.FZWW is ransomware-type malware. It searches for the documents on your disk, encrypts it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your documents inaccessible, this malware also does a lot of harm to your system.

Win32/GenKryptik.FZWW Summary

In summary, Win32/GenKryptik.FZWW virus activities in the infected computer are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • CAPE extracted potentially suspicious content;
  • Unconventionial language used in binary resources: Georgian;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • CAPE detected the DanaBot malware family;

Ransomware has actually been a headache for the last 4 years. It is challenging to picture a more hazardous malware for both individuals and organizations. The algorithms used in Win32/GenKryptik.FZWW (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 currently exists, and possibly will exist. However, that virus does not do all these bad things immediately – it can take up to a few hours to cipher all of your documents. Therefore, seeing the Win32/GenKryptik.FZWW detection is a clear signal that you need to start the clearing process.

Where did I get the Win32/GenKryptik.FZWW?

Typical tactics of Win32/GenKryptik.FZWW injection are typical for all other ransomware variants. Those are one-day landing web pages where victims are offered to download and install the free app, so-called bait e-mails and hacktools. Bait e-mails are a relatively new method in malware distribution – you get the e-mail that mimics some routine notifications about deliveries or bank service conditions changes. Within the e-mail, there is a corrupted MS Office file, or a link which opens the exploit landing page.

Malicious email spam

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

Avoiding it looks quite easy, but still requires a lot of awareness. Malware can hide in different spots, and it is better to stop it even before it gets into your system than to rely on an anti-malware program. Basic cybersecurity awareness is just an important item in the modern world, even if your relationship with a computer remains on YouTube videos. That can save you a lot of time and money which you would spend while looking for a fix guide.
