Heartbleed and Mobile
Heartbleed and Android  I couldn't find any detailed discussion of Android itself or Android apps being vulnerable to the heartbleed attack. Sure some apps are linked against vulnerable versions of OpenSSL but I couldn't find any attack description. If you know anything specific please email me!
Checkout reverseheartbleed.com a heartbleed testing service for clients software (e.g., web browsers).
SMS bulk operators vulnerable to heartbleed, leak 2FA tokens see heise.de (in German)
I'll be speaking at Duo Tech Talks in Ann Abor, MI (this will be a IoT related talk).
I'm on a panel about Internet of Things security at The Security of Things Forum in Cambridge, MA.
Mid-End of May I'll spent some time in the Bay Area for IEEE S&P, with plenty of time afterward to hangout.
I'm also planning to go to ToorCamp, who else is going?
