Abstract:
A method, system and program product for optimizing emulation of a suspected malware. The method includes identifying, using an emulation optimizer tool, whether an instruction in a suspected malware being emulated by an emulation engine in a virtual environment signifies a long loop and, if so, generating a first hash for the loop. Further, the method includes ascertaining whether the first hash generated matches any long loop entries in a storage and, if so calculating a second hash for the long loop. Furthermore, the method includes inspecting any long loop entries ascertained to find an entry having a respective second hash matching the second hash calculated. If an entry matching the second hash calculated is found, the method further includes updating one or more states of the emulation engine, such that, execution of the long loop of the suspected malware is skipped, which optimizes emulation of the suspected malware.
