Are the apps the source of all evil? A security and privacy perspective
The battle for security and privacy has now moved to social media and smartphones. New user behaviors and the integration of these platforms in every day life provide novel opportunities for hackers. I present the two major research thrusts of my group. First, we study social media-based malware and present the techniques and tools we have developed to protect users. Our initial results are scary and interesting: (a) malware is widespread, with half of the monitored users being exposed to at least one malicious post from a friend, and (b) 44% of malware campaigns are enabled by Facebook apps. Second, we briefly highlight our work on tools for enhancing the security and privacy of smartphone users. We focus on smartphone apps and develop tools to profile and understand the threats that these apps introduce. For example, we find that free apps are not as free as we may think, as they consume more battery and bandwidth and interact with suspicious websites. Finally, I discuss our ongoing and future plans along these research areas.
