Ryuk - Ransomware
The ransomware uses AES and RSA encryption and demands between 15 and 50 Bitcoin for the decryption key. The malicious software kills hundreds of processes and services and also encrypts not only local drives but also network drives. The attacks are reported to be targeted at organizations that are capable of paying the large ransom demanded. Variants found in mid 2019 will not infect the system if the computers IP address or computer name is part of a blacklist.
