(Ab)using bash-fu to analyze recent Aggah sample

Intro Recently one of my generic signatures for malformed documents was hit, this type of malformation was used mostly by Zebrocy so i was curious whats cooking. After some analysis it turns out that last stage uses tools that are publicly attributed to Aggah, but to get that we need to tear through multiple layers of downloading scripts. We probably could just run our lure document and collect dropped binaries in a sandbox but where is fun of that?
