For most of my career as a software developer/security researcher I’ve romanticized ‘hardware hacking’. In my late teens and early twenties as I was learning about software development and software security I would occasionally buy Nuts and Volts from Microcenter and read Karl Lunt‘s Amateur Robotics column. Having devoured William Gibson‘s oeuvre in my late… [Read more…]
Earlier this summer Beans attended the weeklong SMT Solver Summer school held at MIT campus in Boston, Mass. Over the last few years having seen some of the presentations by Pablo Sole on DEPLIB, blogposts by Sean Heelan, and having messed around a little bit with the REIL in BinNavi we were really curious to get a… [Read more…]
In 2011, I (Stephen A. Ridley) don’t plan on attending too many conferences that require far away travel for many reasons. 1) My work isn’t as interesting anymore ;-( and 2) I can’t travel as easily with Sammiches. With Boston being in the northeast (close to us) we decided we’d try SourceBoston out for the… [Read more…]
So let’s say that you’re sitting down to a project (perhaps a malware analysis gig, fuzzing something, or just reversing) and you realize that most of the target is implemented in COM/ActiveX Objects. What would really help you starting off on this project is a human readable version (IDL) of the TypeLib associated with the… [Read more…]
Recently I (Stephen A. Ridley) have been doing quite a bit more security research on embedded systems and mobile platforms like phones. This naturally means more development in these areas. A while back I ran into SL4A or Scripting Layer for Android which was (at the time) called ASE or Android Scripting Environment. (Apparently they… [Read more…]

Also, provided here are hopefully some instructions to get this working: Download coddec.rar from wherever Extract into some directory and cd into the directory patch -p1 < coddec.patch… [Read more…]

Now and again I have to disassemble BlackBerry apps. BlackBerries pretty much run all Java code. You might think this would mean everything was .class files and you could jad everything, but this is not the case. Everything gets compiled to “.cod” files, a file format I have found very little information about on the… [Read more…]
So it turns out that there is a useful trick when working with and deobfuscating quasi-encrypted and obfuscated Javascript (like that seen in malware). The other Stephen observed that the function “COlescript::Compile()” in JSCRIPT.DLL is basically the place in the javascript interpreter that equates to an eval(). If you break here at runtime (like so)… [Read more…]
