Our iOS 7 Kernel Exploitation Training in April sold out in less than a month so that we decided to do the training again in July. However this training is well after the release of iOS 7.1 and also after the initial iOS 8 betas, which means we will improve the training material of the iOS 7 Kernel Exploitation Training course to incorporate iOS 7.1 and 8.0 beta changes.
The training in July will take place in the Le Meridien hotel in Frankfurt (Germany) between 21st July and 25th July. It 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 7.1/8.0 beta (as far they are known) 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.
We will start the training with work on some old A4 iOS devices that allow for easier debugging and then
learn how to port our attacks to new devices. For this we have acquired brand new 64bit iPad mini 32GB
(retina+WiFi+Cell) devices for each trainee to take home after the course. These devices also allow us to
go into the changes between the 32 bit and the 64 bit ARM architecture.
At the end of the training you should be able to exploit new vulnerabilities
in the iOS 7/8 kernel that you discover on your own.

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 7.0.4 / 7.0.6
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
Because the release date of iOS 8 is unknown at the moment it is not
possible to predict what changes there might be in the kernel in its
final version. However we will incorporate all the information known
about the iOS 8 kernel from the latest betas until the training into
The topic of persistence or untethering will be discussed although
the kernel land is only partially involved.
all students will take home an iPad mini 32GB (retina+WiFi+Cell) with a retail value of 599,- EUR
(these iPads were just unpacked and tested to ensure they are working correctly, otherwise they are new)
the whole training material (multiple hundred slides) will be handed to the students in digital and printed form
all the SektionEins software and scripts used during the training will be given to the trainees free of charge
This course will not give an introduction to ARM basics. The trainee is
required to understand basic ARM assembly. It is not required to have
previous experience with ARM64 cpus, because their differences are
discussed within the training. Low level ARM CPU knowledge will
be helpful, but is not required for this course - part of it will
be explained within the 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 some basics are understood.
An Apple Mac Notebook is required in order to run OSX and XCode.
Training hands-on exercises will be performed on devices provides by SektionEins.
It is not required for students to bring their own iOS devices.
Every student will be handed an iPad mini 32GB (Retina+Wifi+Cell) at the beginning
of the training that they will work on and can take home after the training.
Students can optionally bring their own iOS device for experiments.
But for best results these devices should run an iOS version which has a public
jailbreak for it.
Students are not required to bring iOS serial cables for older devices to the
training, because these will be provided by SektionEins.
- Legal IDA Pro 6.x license (IDA Pro 6.5 or newer recommended for ARM64 support)
Hexrays for ARM helpful, but not required
BinDiff for IDA helpful, but not required
Mac OS X Mountain Lion 10.8 (or newer), with XCode 5 and iOS 7.0 SDK (or newer)
Additional Software will be made available during the training
The training will be held at the Le Méridien Parkhotel 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).
Attention: The special hotel rate reserved for us has ended 6 weeks before the training.
We offer the following rates for this training. Attention: Trainees paying for the training themselves or companies inside the European Union have to pay VAT on top of the base price.
Very Early Bird (before 17th March)
Early Bird (before 14th April)
Regular (before 26th May)
Late (before 23th June)
Very Late (after 23h June)
