This article explains the issues that occur in case of infection with Kraken Cryptor v2.2 and provides a complete guide on how to remove malicious files and how to potentially recover files encrypted by this ransomware.

Kraken Cryptor v2.2 is a strain of a ransomware family of the same name. The purpose of this threat is to invade computer systems and then encodes files stored on them by utilizing a strong cipher algorithm. During the encryption process, Kraken v2.2 ransomware changes parts of the original code of target files and appends five random capitalized letters and numbers as an extension. Following encryption, all corrupted files remain inaccessible until any efficient recovery solution restores the initial state of their code. One decryption option is offered by hackers at a price of $80. However, since at this point there is no evidence that they possess a working decryptor, it is better to consider the use of alternative recovery methods. You can find a list of the ones proved to be efficient in this removal guide.
