Ransomware are malware programs used by hackers to block access or use of the data and the entire computer system. The aim is to encrypt the data and then extort money for unlocking the data
Crypto Trojans
Crypto Trojans encrypt files, thus making them unreadable for the user. In exchange for a ransom, the user is offered the prospect that the files will be decrypted so that they can be accessed again. A well-known example of such encryption Trojans is Locky.
