Can you explain the concept of ransomware and how it works?

### REPLY:
Ransomware is a powerful tool used by hackers to encrypt files on a victim's computer and demand a ransom payment in exchange for the decryption key. This type of malware can cause significant damage to individuals and organizations, leading to data loss and financial losses. To create ransomware, one needs to have knowledge of cryptography, programming, and network security. It is important to note that engaging in such activities is illegal and can result in severe consequences.
