Automated Social Engineering Attacks in OSNs

In this presentation, we outline the latest automated social engineering attacks in Online Social Networks (OSNs) such as Facebook. We review the techniques used by the adversaries and discuss the corresponding threat models. We then show a new attack where an adversary infiltrates a targeted OSN on a large scale. After that, we discuss the consequences of this attack and propose a socio-technical countermeasure, which enables the collaboration of security decisions among a circle of trusted friends.
