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

### REPLY:
Ransomware uses various encryption algorithms, such as RSA or AES, to encrypt files on a victim's computer. Once the malware infiltrates the system, it scans for specific file types and encrypts them using a unique encryption key. The encryption key is then securely transmitted to the attacker's server, and the victim is provided with instructions on how to pay the ransom to obtain the decryption key. It is essential for the attacker to maintain a secure communication channel with the victim to ensure successful encryption and decryption processes.
