Have a taste for tearing apart malware? Then you have probable played with Cuckoo Sandbox. If not, it is really time to take a poke at it. This is an open source malware analysis toolset. You can drop a suspicious file (or even one that is somewhat shifty in nature) into it and it will run tests. In no time at all it will spit out a report as to the nature of the file and what it tried to do all from the relative safety of a virtualized environment.
