After having received numerous requests to organize an iOS Security and Exploitation Workshop in Europe, we have
created this brand new iOS security course that is entirely focused on the iOS kernel and its exploitation.
It will take place in Frankfurt (Germany) in September, is a full 5-day course and is targeted at exploit developers that want to switch over to iOS.
We will cover the latest iOS 6 (and maybe iOS 7) kernel security features, discuss their weaknesses
and you will learn how to circumvent them. 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 to implement an attack against a real device.
Throughout the training we will work on old A4 iOS devices that allow for easier debugging and then
learn how to port our attacks to new devices.
At the end of the training you should be able to exploit new vulnerabilities
in iOS 6 or 7 that you discover in kernel land on your own.

iOS Kernel Exploit Mitigations
Discussion of all the iOS Kernel Exploit Mitigations introduced
Discussion of various weaknesses in these protections
iOS Kernel Vulnerabilities and their Exploitation
Discussion of previous kernel vulnerabilities used in public jailbreaks
Introduction to kernel exploitation with a DEMO vulnerability
Exploitation of a real kernel vulnerability at iOS 6.1.3
iOS Kernel Jailbreaking
Discussion of all the Kernel Patches applied by iOS Jailbreaks
Handling of New Devices
Discussion of necessary steps to port exploits from old to new devices
While we concentrate on iOS 6.1.3 we will discuss changes
that are already known about the iOS 7 kernel throughout the training
The topic of persistence or untethering will be discussed although
the kernel land is only partially involved.
This course will not give an introduction to ARM basics. The trainee is
required to understand ARM assembly. Low level ARM CPU knowledge will
be helpful, but is not required for this course.
This course will not give basic introduction to exploitation or ROP.
Trainees are required to know concepts like ROP or buffer overflows,
integer overflows, etc...
Trainees will receive about 2 weeks before the training a paper that
covers introductionary information. Trainees are required to read and
work through this document in order to ensure that all software is
correctly installed and the basics are understood.
An Apple Mac Notebook is required in order to run Mountain Lion and XCode.
Training hands-on exercises will be performed on iPod 4G devices running
at iOS 6.1.3 that are provided by SektionEins to all students during the training.
Students can optionally bring their own newer iOS device for experiments
towards the end of the training. But these devices must run an iOS 6
firmware prior to (including) iOS 6.1.4.
Students are not required to bring iOS serial cables to the training,
because these will be provided as take aways from SektionEins.
- Legal IDA Pro 6.x license (latest version recommended)
Hexrays for ARM helpful, but not required
BinDiff for IDA helpful, but not required
Mac OS X Mountain Lion 10.8 , with XCode 4.6 and iOS 6.1 SDK
Additional Software will be made available during the training
The training will be held at the InterContinental Hotel in Frankfurt (Germany). The hotel is located near the main train station of Frankfurt, which is an ICE train ride of about 20 minutes away from the airport of Frankfurt (FRA).
