MITM against T-Mobile Wi-Fi Calling

We released a technical report on our MITM attack against T-Mobile's WiFi Calling service, which I realized I never linked to this here. This was joint work with Jethro Beekman, another EECS grad student at Berkeley. Big takeaway: T-Mobile was great to work with on fixing this vulnerability---their security team is excellent.

We also have a WOOT 2013 paper that covers this and other attacks on cellular systems, but we are still working with vendors on that. Stay tuned.

Update (2013/9/6): Our WOOT 2013 paper is published, and I've posted some details and links to the paper, slides, and video.
