Trailrunner7 writes "A pair of security researchers from Germany demonstrated several techniques at the CanSecWest conference here Wednesday that enable them to remotely reboot, shut down or even completely disable many popular mobile phones with SMS messages. The technique that Nico Golde and Collin Mulliner discussed relies on setting up a GSM network and sending specially crafted SMS messages to handsets. The pair showed a video demonstration of phones from a wide range of manufacturers, including LG, Sony Ericsson, Nokia and others rebooting, freezing and generally acting flaky after receiving the crafted SMS messages they sent."
