Facebook is the privileged target for hackers and cybercriminals, the popular social network is a mine of data that could be used to acquire information on a specific target or to conduct criminal activities involving a large audience (e.g. Serve a malware, conduct a phishing campaign, arrange cyber fraud).Through the analysis of mutual relationship between users an attacker could elaborate the proper strategy to hit a victim, or a group of individuals. There are numerous tools that could be exploited to automatize the reconnaissance process through , and numerous are the functionality that could be used for useful researched.Recently I’ve published a post to describe the work of experts Werrett and Lee that demonstrated how to conduct a powerful analysis using FBStalker, a tool created to find a comprehensive amount of data on any Facebook user.

“FBStalker reverse-engineers the Facebook Graph to find information on every user, the tool does not require a direct friendship with targeted profiles, it just needs to access to parts of victim’s posts marked as public.Through the use of Graph Search data mining activities has become very easy, Graph Search mines Facebook’s vast user data returning personalized results from natural-language queries. Using it is possible to discover what individuals like, where people have visited and if they share those same preferences with their friends.”

The study of friend list is another powerful practice to profile a target, but it is known that through privacy setting Facebook users can make the friend list public or private, if friend list is made private it will be not visible on publicly viewable profile.
