Abstract
A computer-implemented method for detecting malware based on asymmetry includes receiving, via a processor, an application to be tested. The method includes computing, via the processor, a static call graph for the application. The method also includes generating, via the processor, an interprocedural control-flow graph (ICFG) based on the static call graph. The method further includes detecting, via the processor, symbolic path conditions and executable operations along different paths of conditional branches in the ICFG. The method further includes detecting, via the processor, asymmetries based on the symbolic path conditions and the executable operations. The method includes detecting, via the processor, a malicious block based on the detected asymmetries. The method further includes modifying, via the processor, the application based on the detected malicious block.
