Abstract

A method for detecting and blocking a Man-in-the-Middle phishing attack carried out on a client connection which has been fraudulently routed through an anonymous proxy server. An agent downloaded to the client device opens a client direct connection to the security host protecting against the attack and sends a client direct connection ID to the security host for validation. By comparing IP addresses correlated via the validated client direct connection ID, the security host determines whether the original connection is direct (secure) or indirect (attack via phishing proxy). The detection and blocking can be performed by the service provider's server or by a third-party validation server handling all security without additional requirements on the service provider server. In addition to detecting and blocking such attacks, methods for client direct connection ID, as well as automatic transparent and seamless attack circumvention and preemptive circumvention are disclosed.
