Not too much happened or I just missed it because I'm way to busy these days. I'll just update my mobile conference monitor.
Black Hat USA has way more mobile talks then last year. Hacking Androids for Profit by Riley Hassell. ARM exploitation ROPmap by Long Le. War Texting: Identifying and Interacting with Devices on the Telephone Network by Done Bailey. Mobile Malware Madness, and How To Cap the Mad Hatters by Neil Daswani. The Law of Mobile Privacy and Security by Jennifer Granick.
Defcon is a little weak on mobile stuff this year. Only very few talks, one of the being: Mobile App Moolah: Profit taking with Mobile Malware by Jimmy Shah.
