Zatrov Virus – DetailsThe Zatrov mean a ransomware-type infection. Initially, it was revealed by Michael Gillespie. The infection comes from the DJVU ransomware family. Zatrov was elaborated specifically to encrypt all major file types. When the file is encrypted people are unable to use them. Zatrov adds the “.zatrov” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Zatrov, will be renamed into “myphoto.jpg.zatrov.

It actually discusses that the info is encrypted which the only way to bring back it is to use a a distinct decryption key. Regretfully, this is absolutely true.

Another technique of Zatrov is that the victims cannot gain access to the key. The key is kept on a specific server run by the frauds related to Zatrov ransomware.
