Sidejacking

Term used to describe the malicious act of hijacking an engaged Web session with a remote service by intercepting and using the credentials that identified the user/victim to that specific server. Typically, SideJacking is most common on sites that require authentication through a username and password, such as online Web mail accounts as well as social networking sites. SideJacking works only if the site catches a non-SSL cookie, so any Web site that uses SSL exclusively would be safe from SideJackers. SideJacking was first demonstrated by Robert Graham, CEO of Errata Security at Black Hat in 2007.
