BlackLock Ransomware: A Analysis and Removal Guide

BlackLock is a ransomware-type virus that encrypts files and demands ransoms for decryption. It renames encrypted files with a random character string and appends them with a likewise randomized extension. The attackers claim financial motivation and threaten to leak stolen data if the ransom is not paid. Victims are urged to communicate via a Tor website to negotiate a ransom, typically demanded in Bitcoin.
