What Are Ransomwares ? And How To Protect Your Self From Them :

Ransomware is a type of malicious software (malware) that encrypts a victim’s files or locks them out of their system, demanding a ransom payment (usually in cryptocurrency) in exchange for decryption or restored access.

Types of Ransomware

Encrypting Ransomware – Encrypts files and demands payment for the decryption key (e.g., WannaCry, REvil).

1. Locker Ransomware – Locks the victim out of their device without encrypting files (e.g., Police Ransomware).

2. Double Extortion Ransomware – Steals and encrypts data, threatening to leak it if the ransom isn’t paid (e.g., Maze, Conti).

3. Ransomware-as-a-Service (RaaS) – Cybercriminals sell ransomware kits to other hackers, who then distribute them (e.g., LockBit, DarkSide).
