Vulnerability Analysis of MMS User Agents

The Multimedia Messaging Service (MMS) is becoming more popular, as mobile phones integrate audio and video recording functionality. Multimedia messages are delivered to users through a multi-step process, whose end-points are the MMS User Agents that reside on the users’ mobile phones. The security of these components is critical, because they might have access to private information and, if compromised, could be leveraged to spread an MMS-based worm. Unfortunately, the vulnerability analysis of these components is made more difficult by the fact that they are mostly closed-source and the testing has to be performed through the mobile phone network, which makes the testing time-consuming and costly. This paper presents a novel approach to the security testing of MMS User Agents. Our approach takes into account the effects of the infrastructure on the delivery of MMS messages and then uses a virtual infrastructure to speed up the testing process. Our testing approach was able to id...
