This note contains links to multiple LockBit ransomware operations’ Tor data leak sites. It also includes negotiation sites. The note even has a Decryption ID that is required for logging in to talk with threat actors.
Multiple security experts have told BleepingComputer that the “Decryption ID”, however, does not work.
