Karl Virus Ransomware

Karl is a malicious software functioning as typical ransomware. Michael Gillespie, the widely known virus researcher, first found this new name in the DJVU ransomware family.

Karl was created for the sole purpose to encrypt all popular file types. Realistically, as soon as the file encryption is effectively achieved, the users are not able to get access to them. Karl virus includes its own “.karl” to all the encrypted files. For example, the file “price_list.xls”, once modified by Karl, will be entitled as “price_list.xls.karl”. When the encryption is achieved, Karl puts its own distinct text document (_readme.txt) into all the folders that save the encrypted files.

The alert mentioned by text file requesting the random os very similar to the notices provided by other ransomware dangers coming from the DJVU family. The warning basically shows that the information has been secured and the only option to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely true.

One more peculiarity of the Karl infection is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the complete control by the scoundrels who have launched the Karl virus into the web.
