Taipei is definitely one of my favourite cities in the world! I love its “infinite” amount of small shops, in particular at night when lights are on. Streets look so beautiful and busy. Everyone is very friendly and respectful, and most important, I feel very safe. And the food is awesome (thank you Thomas!). I really love it! If you like Asia, Taiwan is a must visit. The only problem is language – English is not widely spoken....
There’s a new attempt at jailbreak detection available at http://appminder.nesolabs.de. It is mostly aimed at Enterprise applications and not AppStore usage. I am not sure about AppStore rules but those tricks will most probably not pass the approval process. AppMinder provides three levels of jailbreak detection and anti-debugging measures. The different levels are related to self-integrity checking and code obfuscation rates. When you generate a new protection, it will give you some plug’n’pray code to plug in into your existent code base....
A reader was asking me some questions related to some stuff I used in my crackme and I decided to release its source code. Enough time went by already and I do not think it has many important secrets. Now, you will have to forgive me but that is one hell of ugly source code! I just cleaned up some dead code and some other minor cleanups. Right now I do not have enough time to fix and clean up the code, even if I really do not like it at all....
I was lucky enough to get my hands on an updated version of interesting multiplatform virus and decided to reverse the OS X part. The original virus is from 2006 by JPanic and it’s called CAPZLOQ TEKNIQ v1.0. The new version adds support to infect OS X binaries, 32 bit x86 only, although it supports infection of fat binaries (the x86 version only). Source code for the original version is available....
One of the changes introduced by Mountain Lion was the removal of the old procmod convention for applications that want to access the task port of a process (aka for reversers, debuggers). Before this change, any binary that was procmod suid group set could access the task port of other processes (running as the same user). Taskgated configuration in Mountain Lion was changed and removed this possibility. Only signed binaries that contain an embedded Info....
