The OS X / iOS Kernel Internals Training usually takes place in Frankfurt (Germany). It is a full 5-day course and is targeted at security researchers that want to learn about the OS X and the iOS kernel in order to e.g. hunt malware in the kernel.
We will cover kernel internals, focussing on strutures important to security researchers. We will discuss its security features, discuss their weaknesses. Every part of the course will start with a lecture introducing you to the topic and end with hands-on exercises, where you use your newly gained knowledge in exercises.
