Krypt is a highly dangerous ransomware-type program that encrypts users’ files and demands a ransom in exchange for their decryption. Victims of this malware experience severe data loss as the original filenames are replaced with randomized strings, followed by the “.helpo” extension — making files completely inaccessible. For example, a file originally named photo.jpg
would be renamed to something like Xc3TaQb.helpo
.
Once Krypt finishes encrypting the system, it alters the desktop wallpaper, places a ransom note in a file named HowToRecover.txt, and even displays a full-screen message before the Windows log-in screen. All of these messages emphasize that files have been both encrypted and stolen, leveraging psychological pressure to scare victims into paying the ransom.
