Cross-Site Identification (XSid)

Names Cross-Site Identification (CSID/XSid): a social network is made an involuntary identifying service. An image link on any third-party site silently drives the logged-in victim's browser to the attacker's SN application, which returns the victim's public name and photo out of context. Demonstrated on Facebook, Bebo and Orkut, including OpenSocial signed requests leaking a stable viewer id.
