Then they install the ransomware, which looks a lot like Windows ransomware. Like Windows-based ransomware encrypts Linux.Encoder files with AES. The symmetric key is then encrypted with an asymmetric encryption algorithm (RSA).

When designing the ransomare the creators have made ​​a big mistake, allowing researchers Bitdefender can identify the AES key without that first with the RSA private key must be decrypted. The ransomware does not use any keys and initialisation vectors for encryption, but leads these two pieces of information on a specific feature in combination with the time of the encryption.
