What is ransomware and how does it work?

### REPLY:
Ransomware is a type of malware that encrypts a victim’s files or locks their computer, making them inaccessible until a ransom is paid. It works by exploiting vulnerabilities in the victim's operating system or software to gain unauthorized access to the system. Once the ransomware gains access, it can encrypt the victim's files using a unique encryption key. The attacker then demands a ransom payment in exchange for the decryption key. If the victim refuses to pay, the attacker may threaten to release sensitive information obtained from the compromised system.
