LSS-NEWS-2010-006A group of researchers have discovered a simple way to reveal the identity of a user based on his interactions with social networks (such as Facebook).

The 'deanonymization' attack uses combination of social network groups and some traditional browser history-stealing tactics. That is group of techniques that allows attacker to peek at a user's URL browsing history so he could see list of visited social network groups. Researchers say that attack is successful because of unique group fingerprint for all users. However successful executing requires visiting of malicious website that contains the attack code. Criminals could use it for executing phishing attacks, criminally fraudulent process of attempting to acquire sensitive information.
