Abstract
Mobile phones are now used by over five billion people, making them the dominant computing platform around the world. This shift has not gone unnoticed — malicious behavior targeting mobile devices has recently been one of the most popular security topics in both academic circles and the popular press. However, the extent to which such threats are actually present in user devices is not well understood. This talk begins with the first study trying to establish ground truth of mobile malware in a major US cellular provider and offers insight into the reality of such threats. I also put such malware into context against another commonly discussed mobile threats — apps exfiltrating private information to advertising networks. Finally, I focus on the recent surge in Caller-ID spoofing and associated attacks, and discuss a mechanism to detect such attacks.
