Mandiant Red Curtain

MANDIANT Red Curtain is free software for Incident Responders that assists with the Analysis of malware. MRC examines executable files (e.g., .exe, .dll, and so on) to determine how suspicious they are based on a set of criteria. It examines multiple aspects of an executable, looking at things such as the Entropy (in other words, randomness), indications of packing, compiler and packing signatures, the presence of digital signatures, and other characteristics to generate a threat "score." This score can be used to identify whether a set of files is worthy of further investigation.
