新一代手机病毒及其对策
New generation of mobile phone viruses and corresponding countermeasures
摘要：
快速增长的智能手机市场，加上其几乎连续的在线存在，使这些设备成为病毒作者的新目标。最近发现MMS（Multimedia Message Services，多媒体消息服务）病毒的拓扑传播受到底层调用图的碎片化的高度限制。在本文中，我们研究MMS病毒的另一种类型的传播行为：扫描。我们发现，混合MMS病毒，包括一定程度的扫描更危险的移动社区比他们的标准拓扑对应。然而，MMS病毒的扫描和拓扑行为的有效性通常可以通过两种控制方法来限制：（i）降低易感手机的市场份额（其运行的操作系统）和（ii）提高监控能力以限制移动病毒发送MMS消息的频率。
英文摘要：
The fast growing market for smart phones coupled with their almost continuous online presence makes these devices the new targets of virus writers. It has been recently found that the topological spread of MMS (Multimedia Message Services) viruses is highly restricted by the underlying fragmentation of the call graph. In this paper, we study MMS viruses under another type of spreading behavior: scanning. We find that hybrid MMS viruses including some level of scanning are more dangerous to the mobile community than their standard topological counterparts. However, the effectiveness of both scanning and topological behaviors in MMS viruses can generally be limited by two controlling methods: (i) decreasing susceptible handsets' market share (OS it runs) and (ii) improving monitoring capacity to limit the frequency in which MMS messages can be sent by the mobile viruses.
