So what are we supposed to do if fancy decompiling fails? We disassemble it.įor this purpose I used the Robust ActionScript Bytecode Assembler (RABCDAsm) tool chain which is written in D and open source. Unfortunately, the recompiled version wouldn’t start anymore, so both tools failed for that purpose. It decompiled my target successfully and I was able to apply my modifications as well as to recompile the application. The first one actually crashed while loading my target executable, so I switched to JPEXS right away.

JPEXS Free Flash Decompiler (free, open source).Sothink SWF Decompiler (commercial product).So I fired up a quick Google search and tried two decompilers compatible with Mac OS X: The first thing that came on my mind when I played with the flash based application was to decompile, modify and recompile it.

I did some brief analysis on the target executable and quickly figured out it actually only was a wrapper containing a. I didn’t really do much reverse engineering lately but last night I attempted to unlock the trial version of a language course.
