URL : Anubis : Analysing Unknown Binaries
About : Anubis is a tool for analyzing the behavior of Windows PE-executables with special focus on the analysis of malware. Execution of Anubis results in the generation of a report file that contains enough information to give a human user a very good impression about the purpose and the actions of the analyzed binary. The generated report includes detailed data about modifications made to the Windows registry or the file system, about interactions with the Windows Service Manager or other processes and of course it logs all generated network traffic. The analysis is based on running the binary in an emulated environment and watching i.e. analyzing its execution. The analysis focuses on the security-relevant aspects of a program's actions, which makes the analysis process easier and because the domain is more fine-grained it allows for more precise results. It is the ideal tool for the malware and virus interested person to get a quick understanding of the purpose of an unknown binary.
