Detecting Environment-Sensitive Malware

Free registration required

Executive Summary

The execution of malware in an instrumented sandbox is a widespread approach for the analysis of malicious code, largely because it sidesteps the difficulties involved in the static analysis of obfuscated code. As malware analysis sandboxes increase in popularity, they are faced with the problem of malicious code detecting the instrumented environment to evade analysis. In the absence of an "Undetectable", fully transparent analysis sandbox, defense against sandbox evasion is mostly reactive: sandbox developers and operators tweak their systems to thwart individual evasion techniques as they become aware of them, leading to a never-ending arms race.
