Malware known as KillDisk, which has been used in hack attacks tied to espionage operations, has been given an update. Now, the malware works on Linux as well as Windows systems and includes the ability to encrypt files, demand a bitcoin ransom and leave Linux systems unbootable. The ransom demand is the same for both Linux and Windows systems: 222 bitcoins, currently worth about $210,000. It’s not even clear if attackers would be able to provide a decryption key – at least for the Linux version.”]
