Stealthy Video Capturer: A New Video-Based Spyware in 3G Smartphones

This paper investigates video-based vulnerabilities in 3G Smartphones. Particularly, it designed a new video-based spyware, called Stealthy Video Capturer (SVC). SVC can secretly record video information for the third party, greatly compromising Smartphone users' privacy. It implemented the spyware and conduct extensive experiments on real world 3G Smartphones. Its experimental results show that the spyware can capture private video information with unremarkable power consumption, CPU and memory occupancy, hence being stealthy to Smartphone users. Moreover, SVC can naturally be resistant to almost all commercial anti-virus tools, like McAfee, Kaspersky and F-Secure mobile version.
