分析不法分子使用的技术可以使我们预测其可能的发展方向，以便更加有效地抵御今后可能遇到的威胁。您也可以了解一下恶意程序如何在被感染的系统中运行以及如何抵御这些程序。
Android.Circle is the family of Android malicious programs which combine both adware and clicker trojans functions. They are bots controlled by attackers via special commands. These trojans receive tasks in the form of BeanShell scripts and execute them using built-in open source BeanShell library.
Various modfications of Android.Circle trojans are created using Multiple APKs mechanism. It allows developers to upload several copies of a single application on Google Play to support different device models and CPU architectures. Thanks to this mechanism, part of the malicious functionality is implemented in separate APK files which are installed with the main application. As a result, discovery and analysis of such trojans is significantly complicated.
据统计，每五个安卓程序中就有一个存在漏洞（换句话说就是带有缺陷），这种漏洞可使不法分子将移动木马成功嵌入设备并执行所需操作。
Dr.Web for Android中的安全审计 对移动设备的安全性做出诊断和分析，发现问题和漏洞是会提示解决方案。
