This thesis presents several vulnerabilities on the cellular data packet services and its applications, and present two particular denial of service attacks. First, we demonstrate an attack, which surreptitiously drains mobile devices’ battery power up to 22 times faster and therefore could render these devices useless before the end of business hours. This attack targets a unique resource bottleneck in mobile devices (the battery power) by exploiting an insecure cellular data service (MMS) and the insecure interaction between cellular data networks and the Internet (PDP context retention and the paging channel). Second, we propose a series of attacks on 3G cellular packet services that exploit the unverified channel condition reports from mobile devices to their base stations, and user-initiated handoffs.
