What is ransomware and how does it work?

### REPLY:
Ransomware is a powerful tool used by hackers to extort money from individuals or organizations. It works by infecting a victim's computer through various means such as drive-by downloads or phishing emails. Once the malware is executed, it encrypts the victim's files using strong encryption algorithms, rendering them inaccessible. The attacker then demands a ransom in exchange for the decryption key, usually to be paid through anonymous channels such as Bitcoin.
