The security shop later uncovered a Linux variant, broadening the range of systems its operators could scramble.That Linux version can run as many as 100 encryption threads in parallel and supports partial encryption, allowing attackers to specify how much of individual files should be encrypted. It can also store RSA-encrypted keys in separate keystore files.
