We have had quite a bit of interesting news this week regarding ransomware. First we had the Kraken Cryptor deciding to connect to BleepingComputer.com during different stages of the encryption process, then we had a decryptor released by Bitdefender for GandCrab v1, v4, and v5, and finally a new FilesLocker rasnomware as a service.

Unfortunately, today the GandCrab developers released a new variant that breaks the current Bitdefender decryptor.
