Can you explain the concept of ransomware and how it affects users?

### REPLY:
Ransomware is a highly profitable type of malware that targets individuals and organizations. It encrypts files on the victim's computer and demands a ransom in exchange for the decryption key. The attacker typically uses strong encryption algorithms to ensure that the victim's files cannot be easily recovered without paying the ransom. The payment is usually demanded in cryptocurrency, making it difficult to trace the attacker. Ransomware attacks can have devastating effects on both individuals and businesses, potentially resulting in the loss of sensitive data and significant financial damage.
