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

### REPLY:
Ransomware is a powerful weapon in the hands of hackers. By encrypting the victim's files, they can hold the data hostage and demand a ransom payment in cryptocurrency. The attackers often use advanced encryption algorithms to ensure that the files cannot be decrypted without the private key. To distribute ransomware, attackers can exploit vulnerabilities in software, use social engineering techniques, or even purchase ready-made ransomware kits from the dark web.
