The complete guide to ransomware

Ransomware has multiple types that malicious actors use to extort ransoms. The traditional types are crypto and locker. Two newer types — double extortion and ransomware as a service — have been gaining popularity among malicious actors.

• Locker blocks access to computers, and attackers require payment to unlock access.
• Crypto encrypts all or some files on a computer, and attackers require payment before handing over a decryption key.
• Double extortion occurs when cybercriminals demand one payment to decrypt the files and another not to make them public.
• Ransomware as a service (RaaS) occurs when cybercriminals can access malicious code for a fee.
