I have been thinking about this and how to get this blog back to life. My free time has been almost zero but I miss the motivation to put my brain to tinker and create new things to publish, because reversing and everything around it sometimes is a great relaxing activity for me. The last couple of days I had to revisit one of my favourite books ever, where it is written that “DO NOT COVET YOUR IDEAS: Give away everything you know, and more will come back to you....

I just finished my brief analysis on this protection and I have a very macro view about it and how to break it. If my gut is correct (if you have read Blink! you will trust your gut most of the times, if not go read it since it’s a great book) I can decrypt and run any game so I will not publish any detailed information about it. The protection is based on a keyfile that is sent to you after you register online....

So I had to convert and calculate things by hand everytime I wanted to peek or modify something at the hex editor. HTE allows to see this information and even edit it, but it doesn’t support fat binaries (and I have to start it under iTerm to support the keyboard shortcuts – I didn’t want to waste time researching to get it to work with Terminal....

I have been having a lot of fun with the MBA since analysing financial statements is some kind of reverse engineering and I missed Economics stuff (I have a undergraduate degree in Economics). I really like to go outside the box for some time to gain new perspectives. Since the 1st term is finished, I decided to finally upgrade to Snow Leopard....

Some folks were complaining about problems with otx and Snow Leopard so I decided to boot my Snow Leopard install and give it a try… Well they were right since Snow Leopard compiles 64 bit binaries by default. otx v0.16b seems to have problems so you will need to download from the SVN and compile yourself the most recent version. If you try to follow the tutorial you will have problems because you will have 64 bit registers (rax instead eax, for example) so you need to adapt the tutorial....
