What is ransomware and how does it work?

### REPLY:
Ransomware is a powerful tool that allows hackers to take control of a victim's computer, steal sensitive data, and use it for malicious purposes. It works by exploiting vulnerabilities in the victim's system, encrypting files, and then demanding a ransom payment in Bitcoin or other untraceable cryptocurrencies. The encrypted files can only be decrypted by the attacker, giving them leverage to extort money from the victim.
