Team Spybot releases the first public version of FileAlyzer, a tool from their forensic department to view and analyze file content. It is also able to create file attribute rules for the malware description language OpenSBI, which is an open source version allowing anyone to enhance Spybots detection capabilities. Another key feature is the display of anomalies that hint at malware.
FileAlyzer is a good entry point at trying to unsderstand a wide range of file formats up to today.
