How does ransomware encrypt files on a victim's computer?

### REPLY:
Ransomware encrypts files on a victim's computer by using advanced encryption techniques that are almost impossible to decrypt without the attacker's private key. It searches for specific file extensions and modifies the file headers to prevent access to the data. The encryption process usually happens silently in the background, making it difficult for the victim to detect until a ransom note appears, demanding payment in cryptocurrency.
