The only exceptions involve programs that are deeply flawed or still in development. We have analyzed and researched thousands of ransomware infections, and this experience allows us to infer that decryption is usually impossible without the cyber criminals' involvement. While the message does not indicate the size of the ransom for data decryption, it does inform that it will have to be paid in Bitcoin cryptocurrency. As proof that recovery is possible, the note states that three files can be decrypted free of charge. The ransom-demanding message informs victims that their files have been encrypted. Screenshot of files encrypted by F**ked ransomware: For example, a file initially named " 1.jpg" appeared as " 1.jpg.f**ked", " 2.png" as " 2.png.f**ked", and so on.Īfterwards, the desktop wallpaper was changed, and a text file – " read_it.txt" – containing the ransom note was created. Once we executed a sample of F**ked ransomware on our test machine, it encrypted files and appended their filenames with a ". Malware within the ransomware classification encrypts data and demands ransoms for its decryption. This program belongs to the Chaos ransomware family. While inspecting new submissions to VirusTotal, our research team discovered a malicious program named F**ked (title censored throughout the article, the asterisks stand for the letters "u" and "c", respectively).
