Platform Win32

Originally, Worm.Win32.Cridex was a worm that spread through removable disks. The worm evolved over the years to become full-featured banking malware.

Later versions of the malware are able to perform the following actions:
• Web injects
• Screenshots and clickshots (pictures of web pages when the user clicks the mouse)
• Blocks access to certain Internet sites
• Redirecting the user from one URL to another

Worm.Win32.Cridex carefully hides its command-and-control server by using a P2P network and proxy server.

Communication with the command-and-control server uses symmetric encryption, plus additional XOR encryption for the configuration file received from the command-and-control server.
