Visible to the public TWC: Small: Combating Environment-aware Malware

Tools for dynamic detection of malicious software ("malware"), such as antivirus software, often create a protected "analysis environment" (or "sandbox") in which to test suspicious software without risk to the computer system. Malware authors have responded by developing environment-awareness techniques, to enable their malware to recognize and behave differently in a sandbox environment, thereby evading detection. Authors of defense software are endeavoring to ensure that analysis environments exhibit realistic characteristics.
