Query: OSSINT - Open Source Social Network Intelligence An efficient and
  effective way to uncover "private" information in OSN profiles   Online Social Networks (OSNs), such as Facebook, provide users with tools to
share information along with a set of privacy controls preferences to regulate
the spread of information. Current privacy controls are efficient to protect
content data. However, the complexity of tuning them undermine their efficiency
when protecting contextual information (such as the social network structure)
that many users believe being kept private.
  In this paper, we demonstrate the extent of the problem of information
leakage in Facebook. In particular, we show the possibility of inferring, from
the network "surrounding" a victim user, some information that the victim set
as hidden. We developed a system, named OSSINT (Open Source Social Network
INTelligence), on top of our previous tool SocialSpy, that is able to infer
hidden information of a victim profile and retrieve private information from
public one. OSSINT retrieves the friendship network of a victim and shows how
it is possible to infer additional private information (e.g., user personal
preferences and hobbies). Our proposed system OSSINT goes extra mile about the
network topology information, i.e., predicting new friendships using the
victim's friends of friends network (2-hop of distance from the victim
profile), and hence possibly deduce private information of the full Facebook
network. OSSINT correctly improved the previous results of SocialSpy predicting
an average of 11 additional friendships with peaks of 20 new friends. Moreover,
OSSINT, for the considered victim profiles demonstrated how it is possible to
infer real life information such as current city, hometown, university,
supposed being private.
