Online Social Networks (OSNs) such as Facebook have become ubiquitous in the past few years, counting hundreds of millions of people as members. OSNs allow users to form friendship relationships, join groups, communicate and share information with friends. The tremendous popularity of OSNs has naturally made them an appealing target for privacy compromising attacks. In this abstract we propose a novel attack against tightly knit OSN communities. Such (artificial) communities consist of users that know well each other and that are reluctant to accept other users as friends. Becoming a member of such a community may be only a first milestone for the attacker. Harvesting private information of members of such communities and following up with offline attacks may be the longer term benefit.
