|Abstract=W32.Silon is new malware variant that intercepts Internet Explorer web browser sessions, and has been associated with fraud incidents at several large banks. Trusteer retrieved and analyzed a sample of this two headed Trojan which is designed to steal generic login information and commit bank-specific fraud.
 
To steal user credentials, W32.Silon performs its initial attack when a user initiates a web login session and enters their username and password. The malware intercepts the login POST request, encrypts the requested data, and sends it to a command & control (C&C) server.
