This virus is just an identical creation of older versions including Msop, Kodg, Grod, and many more. All of them are able to perform complex encryption technique using advanced cipher that will totally lock the target files. Hets ransomware is very specific on encrypting user’s files like photos, images, spreadsheets, databases, presentations, movies, drawings, archives, and other usual data.

Hets ransomware operates discreetly for the first few minutes, while it is still busy fetching other executable files from a remote server. Once it has completed installation of all components, it starts to decrypt files using a sophisticated encryption technique. Even at this moment, users will never sense the attack. Though, the encryption process may diminish system performance because it consumes computing resources during this period.
