Description: Sylvain Munaut, Independent ResearcherRecent years have seen a dramatic drop in the barrier to entry into GSM research. A couple of years ago, tools like OpenBTS & OpenBSC have appeared, allowing anyone to run an experimental GSM network with a relatively low budget. Much more recently, Osmocom-BB bringed MS-side experimentation at an even lower budget. This talk presents an exploit discovered while working on those projects that allows to perform a DOS on a specific target: from its first inception to its actual implementation on a TI Calypso based phone with a custom firmware. This talk will also cover other interesting tricks possible with modified phones, like using them as a cheap alternative to USRP for passive listening for instance.Sylvain Munaut is a Computer Science and Electrical engineer with a lot of interest for free and open source software. He.s been involved in a wide range of projects, both hardware and software, such as: porting and maintaining Linux 2.6 to new platforms (MPC5200), image signal processing on FPGA (JPEG2k), embedded systems hadware design or even work on web-applications. A little less than 2 years ago, he turned his interest to GSM and progressively became involved with projects such as OpenBSC, OpenBTS, airprobe, and more recently Osmocom-BB.
