Ransomware revival

Source: The Register

Ransomware is an old idea, but it has never really become mainstream. The idea is that you infect a computer with a virus and encrypt files, demanding money for a decryption tool, or just threaten to delete files, or similar. Malware authors are trying the concept again with a new malware strain called Gpcode-AI (AKA Sinowal-FY), which "encrypts data on compromised machines before demanding money from users to decrypt it."
