Ransomware's latest new threats: CryptoWall & Chimera
By Jeandre de Beer / Pc World
Ransomware thieves have come up with creative new schemes.
Current ransomware typically encrypts victims’ data and then threatens to delete the key if payment is not made. The latest variant of the CryptoWall malware, however, now scrambles the file-names on infected computers, making it even more difficult for victims to recover without buying the key from the attackers.
Potentially worse, another ransomware operation, known as Chimera, has threatened to publish the data of any non-cooperative victim—whether business or consumer—to the Internet.
The operation, which currently aims at German targets, demands the payment of almost 2.5 bitcoins, or more than US $800, according to German cyber-security site Botfrei, which reported the initial attack.
“To frighten the user even more, the message indicates the threat to publish personal data and pictures somewhere on the internet – if user doesn’t pay the bribe”
– Botfrei’s analysis of the attack.
