Some comments on smartphone botnet C&C over SMS from Shmoocon 2011: this is basically a redo of my iBots paper. The only difference is the implementation for Android in place of our iPhone implementation.
Also from ShmooCon: Attacking 3G and 4G mobile telecommunications networks looks quite interesting.
Sadly I didn't find the slides for the other interesting talks, especially for TEAM JOCH and the mTan talk. Also what about the video streams from ShmooCon, were they recorded?
Interesting story: Would-Be Suicide Bomber Killed by Unexpected SMS From Mobile Carrier if this is true...
