快速增长的智能手机市场加上其几乎恒定的在线存在，使这些设备成为恶意代码（病毒）编写者的新目标。使问题更加严重的是，这些设备的安全级别远远低于个人电脑中使用的最新技术水平。最近发现，多媒体消息服务（MMS）病毒的拓扑传播受到呼叫图的潜在碎片的高度限制，这里的术语拓扑是指明确使用呼叫图拓扑来查找易受攻击的电话。在本文中，我们研究了MMS病毒的另一种传播行为，即通过生成一个随机的号码列表来定位易受攻击的手机，通常被称为扫描。我们发现，混合MMS病毒，包括一定程度的扫描更危险的移动的社会比他们的标准拓扑对应。有趣的是，这篇论文表明，MMS病毒的拓扑和扫描行为可能会更具有破坏性，在高和低的市场份额的情况下，分别。研究结果还表明，如果有足够的时间，复杂的病毒可能会感染很大一部分易受感染的手机而不被发现。幸好，随着电话供应商监察能力的提高，以及受感染电话及时安装修补程序，彩信病毒的蔓延是可以控制的。我们的研究结果使人们更好地了解如何防止手机病毒的传播，即使是在扫描等新行为的情况下。
The fast growing market for smart phones coupled with their almost constant on-line presence makes these devices the new targets of malicious code (virus) writers. To aggravate the issue, the security level of these devices is far below the state-of-the art of what is used in personal computers. It has been recently found that the topological spread of multimedia message service (MMS) viruses is highly restricted by the underlying fragmentation of the call graph-the term topological here refers to the explicit use of the call graph topology to find vulnerable phones. In this paper, we study MMS viruses under another type of spreading behavior that locates vulnerable phones by generating a random list of numbers to be contacted, generally referred to as scanning. We find that hybrid MMS viruses including some level of scanning are more dangerous to the mobile community than their standard topological counterparts. Interestingly, this paper shows that the topological and scanning behaviors of MMS viruses can be more damaging in high and low market share cases, respectively. The results also show that given sufficient time, sophisticated viruses may infect a large fraction of susceptible phones without being detected. Fortunately, with the improvement of phone providers' monitoring ability and the timely installations of patches on infected phones, one can contain the spread of MMS viruses. Our findings lead to a better understanding on how one could prevent the spread of mobile-phone viruses even in light of new behaviors such as scanning.
