提升多维特征检测迷惑恶意代码

针对迷惑恶意代码识别率较低的问题,提出一种基于提升多维特征的迷惑恶意代码检测算法.该算法在对迷惑恶意代码反汇编后进行静态分析,从Opcode分布序列,调用流图特征、系统调用序列图这3个特征维度对恶意代码家族特征进行归纳和分析,结合统计和语义结构特征表现恶意代码"行为"特性,从而对分类结果加权投票后给出迷惑恶意代码家族判...

Obfuscated Malware Detection Based on Boosting Multilevel Features

To cope with the problem of the low accuracy in detecting obfuscated malware, an algorithm to detect obfuscated malware based on boosting multi-level features is presented. After a disassembly analysis and static analysis for the obfuscated malware, the algorithm extracts features from three dimensions: opcode distribution, a function call graph, and a system call graph, which combines the statistic and semantic features to reflect the behavior characteristic of the malware, and then gives out the decision result based on weighted voting for a different feature analysis. It has been proven by experiment that the algorithms have a much higher accuracy on the testing dataset.
