Trojan.Win32.Zolk is ransomware-type malware. It looks for the files on your disk drives, ciphers it, and after that asks you to pay the ransom for getting the decryption key. Besides making your documents inaccessible, this virus also does a lot of damage to your system.

Trojan.Win32.Zolk Summary

In total, Trojan.Win32.Zolk virus activities in the infected PC are next:

  • Sample contains Overlay data;
  • The binary contains an unknown PE section name indicative of packing;
  • Authenticode signature is invalid;
  • Anomalous binary characteristics;
  • Encrypting the files located on the victim’s drives — so the victim cannot use these files;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-malware programs

Ransomware has actually been a major problem for the last 4 years. It is difficult to realize a more damaging malware for both individuals and corporations. The algorithms utilized in Trojan.Win32.Zolk (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have a lot more time than our galaxy actually exists, and possibly will exist. However, that malware does not do all these horrible things immediately – it may require up to a few hours to cipher all of your documents. Therefore, seeing the Trojan.Win32.Zolk detection is a clear signal that you should begin the removal process.

Where did I get the Trojan.Win32.Zolk?

Ordinary tactics of Trojan.Win32.Zolk distribution are typical for all other ransomware examples. Those are one-day landing websites where victims are offered to download and install the free software, so-called bait emails and hacktools. Bait e-mails are a relatively new tactic in malware spreading – you get the email that simulates some regular notifications about deliveries or bank service conditions changes. Inside of the e-mail, there is a malicious MS Office file, or a 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 fairly uncomplicated, but still requires tons of focus. Malware can hide in different spots, and it is better to prevent it even before it goes into your system than to trust in an anti-malware program. Simple cybersecurity awareness is just an important item in the modern-day world, even if your interaction with a PC remains on YouTube videos. That may save you a great deal of time and money which you would spend while searching for a solution.
