See you in Asia!

I will be presenting in Taiwan at HiTCON, and in Seoul at Secuinside. If you are there, come and say hi! I don’t bite. The HiTCON presentation will be focused on OS X malware and Secuinside about starting reversing adventures in OS X/iOS. While slides shouldn’t be the presentation main focus, I’m trying to make them usable for everyone outside the conferences. It’s not an easy task and the introduction to reversing is revealing itself much harder than I thought....

A little social and economics experiment

I have a passion for the Human brain and Human behavior and I love to experiment with anything. My birthday is near so it’s a good time to go forward with this idea. The starting point is that this blog is absolutely non-profit oriented and that status will remain forever – no banners, no donations, etc. I do it purely for fun, pleasure and knowledge improvement, altough it generates positive externalities (aka work!...

4th anniversary...

This blog is more or less 4 years old (the first draft post is from 2007/09/25)… Uau, time passed by quickly! Mistakes were made, valuable lessons were learnt, new tricks developed, knowledge improved, and most important, fun! I created this blog because there was so little public information about reversing in OS X. The act of sharing information and knowledge helps you in the research and learning process. Unfortunately I cannot share as much as I wanted to – the world is full of greed and stupidity (read Survival of the Stupidest) and someone will always misuse information....

The sad state of reverse engineering software/hardware protections

I have just finished reading the legal papers served against Geohot regarding the PS3 jailbreaking/cracking/private keys/etc. It shows the sad state that we have reached into reverse engineering and society as a whole. It’s a fight between knowledge and profit, and in the middle there is a grey area called piracy. My passion for knowledge is very deep and I like to try to understand everything I can. I remember the day I had my Commodore Amiga 500 and someone sent me a disk with a special menu that I never saw before....
