Cool Virus Ransomware

Cool is a destructive software application working as typical ransomware. Michael Gillespie, the popular virus researcher, first discovered this new name in the DJVU ransomware family.

Cool was developed for the sole purpose to encrypt all popular file types. Rationally, as soon as the encryption is effectively achieved, the users are unable to get access to them. Cool ransomware adds its own “.cool” to all the encrypted data. For instance, the file “price_list.xls”, once crypted by Cool, will be entitled as “price_list.xls.cool”. As soon as the file encryption is accomplished, Cool puts its own unique text document (_readme.txt) into all the folders that save the encrypted files.

The alert stated by _readme.txt requesting for the random os really similar to the notices offered by other ransomware dangers coming from the DJVU family. The warning essentially indicates that the files have been secured and the only solution to get access to it is to use a distinct standalone key. Regretfully, this declaration is definitely real.
