Stupid question, but if I wanted to recreate Runa's analysis to learn these tools, where do I go to get it?

I clicked over to Wikileaks + Kapersky's post, interested in possibly writing a small shell script to automate running some of these commands on a given file as a weekend project, but it'd be hard to test such a tool w/o the original binary.

(Maybe it's just been a long day and I'm missing a plainly labeled link, and if so, I apologize for not RTFMing hard enough :) )
