Control protocols used by service providers to communicate and control cell phones can pose a risk. Mathew Solnik and Marc Blanchou, both researchers with Accuvant Labs, have reverse engineered these controls to learn how they work. Their research revealed flaws in how the communication is handled and implemented. They will demonstrate how over-the-air code execution can be performed on GSM, CDMA and LTE networks that can affect Android, iOS, Blackberry and embedded machine-to-machine devices. The pair plans to release tools for protecting against these threats.
