One thing that really bothered me for a long time while debugging is the need to calculate the libraries loaded addresses versus the addresses at disk if you want to follow and comment library code in IDA. While the ASLR slide can also be disabled when starting processes (or even attaching by disabling it first in the Mach-O header) sometimes I want to attach to ASLR enabled processes and once again I need to compute values without the slide to follow in IDA....

Last week ESET released a Rootkit Detector tool for OS X. I finally gave a look at it today and as I suspected it is useless (unless rootkit authors are not reading my slides like ESET does not seem to). The only thing it appears to be doing is to check if sysent pointers were modified. Let’s be honest, it’s useless in particular when they mention they have limited visibility into OS X rootkits....

Eight days and 10 flights later I am back from SyScan360 in Beijing. It was my first visit to China and I had lots of fun observing many things that I only “knew” from reading. The scale and dimension of everything in Beijing is quite a surprise. No wonder why every Western company wants to be there. We had great food and an awesome visit to the Great Wall. A big thank you to the boys and girls from the organization for all their hard work and dedication....

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....
