Abstract
A method for detecting and blocking Javascript hijacking attacks, comprising checking if an incoming request belongs to a valid session established between a client and a trusted server. When said incoming request does belong to a valid session, it is checked if a Referer header of said incoming request includes a valid domain name. The incoming request is marked as suspicious, when said incoming request does not include a valid domain name. It is checked if a respective response of said suspicious incoming request includes a script code. A preventive action responsive to a user input is taken when said respective response includes a script code.
