摘要
间谍软件是攻击者广泛采用的一类信息窃取类恶意软件,具有高威胁性、高隐蔽性等特点.间谍软件在实施窃密行为时通常采用触发执行策略,使得基于软件行为的动态检测方法难以在短时间内将其捕获,故上述方法检测间谍软件效果不佳.针对该问题,本文采用主动诱导间谍软件执行窃密行为的思路,从应用程序编程接口(Application Programming Interface,API)层面分析不同诱导操作和诱导强度对间谍软件的不同诱发效果,进而提出一种基于诱导机制的间谍软件检测方法(Spyware Detection Method based on Inducement Mechanism,SDMIM).SDMIM包含诱导操作筛选、软件“活跃度”计算、间谍软件判别3个阶段,能够适用于多种类型间谍软件的诱导式检测.实验结果表明,SDMIM能够在包含5种不同类型间谍软件的样本集上获得95.98%的检测准确率.
As a kind of information-stealing software,spyware is featured with high threat and concealment and is widely exploited by attackers nowadays.Since the stealing behavior is executed under a specific trigger strategy,it can hardly be captured by the mainstream malware detection methods based on dynamic behavior analysis in a short time.Frequently,the corresponding performance of spyware detection is below expectation.To tackle this problem,in this paper,the influence of different inducement operations and inducement strengths on the inducement effects of spyware from the(Application Programming Interface,API)level is firstly analyzed by introducing the idea of actively inducing spyware to perform its secret stealing behavior.Then,a Spyware detection method based on inducement mechanism(SDMIM)is proposed.SDMIM consists of three phases:inducible operation filtering,software"activity"calculation,and spyware discrimination.It is fit for the inducible detection of various types of spyware.Experimental results show that SDMIM can achieve an accuracy of 95.98%for detecting a dataset consisting of five kinds of spyware.
