This is more of a privacy talk than a security talk. The nature of mobile WiFi device behavior, combined with a lack of user awareness (or attention), could lead someone not only to know what device you use, but also where've you been (and possible where you're heading to), where you work, and in some cases who you are. Some users are security-cautious and use VPNs when connecting company-provided devices to public hotspots, but still there are a large number of people that use a personal mobile device to check corporate emails and other resources. We will also cover how some applications in mobile devices could be spilling out important information about your privacy. This presentation will introduce the proof-of-concept tool Mobile Snitch, which provides easy access to this information.
