| CrypKey 5.4 and the Power of (Self-) delusion
Take a cool glass of your favourite drink,
sit back, and read this superb essay very slowly, take delight
as exefoliator walks you through the CrypKey codewoods from start
to finish, even lending time to fix the developers bugs (are you
listening CrypKey developers? ;-) ). This is exactly the ... Read More >> |

I had read in the past a challenge which consisted in transforming the windows’ notepad into a shareware. I have no idea
if this has already been done, and as I have always been excited by Reverse Engineering, I have always wanted to write an

| Adding functions to any program using a DLL
| Adding functions to any program using a DLL
Some time ago I have worked on Douby’s ”ReverseMe 1” and added missing functions to the program. After doing this I
looked for a way to make this process easier. It’s very uncomfortable to code with HIEW, especially if you must change the
finished code. Suddenly I got an idea: why not writing a ... Read More >> |

| Reverse Engineering the Service Control Manager (SCM)
The SC Manager exported API functions are located in ADVAPI32.DLL (winsvc.h header file in the platform sdk). These functions will ALL end up calling RPCRT4.DLL’s NdrClientCall2. If you want to do a lot of tracing, the madness begins there.

| Coding Smart And Dynamic Code - For better protections, and for the art of it!
Running code is beautiful, isn’t it? Small islands of code
floating in a vast sea of data. Those code islands must run
in a strict, pre-defined way in order to work. Normally you
would have dozens of files in memory, and even more threads,
running on a single CPU. The outcome can be a cool 3D
