Speech Title: Online Social Networks: Malware Threats and Countermeasures in Relation to Topological Network Properties
Abstract: The popularity and diverse uses of online social networks (OSNs) have given incentives to hackers and cybercriminals to carry out attacks using malicious software (malware). Given very large populations on social networks (e.g., 2.6 billion users on Facebook), a successful attack can result in tens of millions of user profiles being compromised and computers and devices being infected. This presentation provides an overview of malware threats in OSNs and countermeasures. In this talk, I will first present topological properties of OSNs, namely, low average network distances, power-law distributed node degrees, and high clustering coefficients. I will then discuss different types of malware targeting OSN users as well as countermeasures against OSN malware. The presentation also highlights how the topological properties of OSNs affect the propagation of
malware and design of countermeasures.
