SektionEins in cooperation with Antid0te organises an iOS Kernel Exploitation Training in Berlin in December 2016.
The SektionEins and Antid0te UG iOS Kernel Exploitation Trainings in 2014-2016 have been so successful that former trainees, tricks, techniques and vulnerabilities from the training have been directly involved in the making of some of the public iOS jailbreaks. Furthermore several of our former attendees can now be seen credited by Apple for security bug fixes in recent iOS and OS X releases. However Apple's internal development of the iOS kernel never stands still and at least once a year around October when the next major iOS version is released new changes have been made to the kernel to add new security mitigations or to defeat previously used attacks.
Especially the release of iOS 10 with its overhauled kernel zone heap implementation has brought drastic changes to the landscape of iOS kernel heap exploitation. Therefore our late 2016 training has once again been updated to contain the latest changes and new exploit mitigations that you can find in iOS 9.3.x and iOS 10 beta.
The next training at the end of the year at the beginning of December 2016. Unlike previous trainings it will happening in Berlin in the RAMADA Hotel Berlin - Alexanderplatz between December 5th and 9th 2016. It is a full 5-day course and is targeted at exploit developers that want to switch over to iOS.
The 2016 December edition of the training will focus on 64 bit iOS devices and most of the work will be performed on 64bit iPod touch 16GB (64 bit) devices that each trainee can take home after the course. These devices will be running iOS 9.x.
NEW: This training will offer attendees the chance to select topics of their choice before the training. We will then integrate the most wanted topics among the trainees into the training.
The goal of this training is to enable you to exploit new vulnerabilities in the iOS kernel that you discover on your own.
The following list of topics might change slightly before the course. (Please check every now and then to see an updated list of topics.)
- How to set up your Mac and Device for Vuln Research/Exploit Development
- How to load own kernel modules into the iOS kernel
- How to write Code for your iDevice
- Damn Vulnerable iOS Kernel Extension
Low Level ARM / ARM64
- Differences between ARM and ARM64
- Exception Handling
- Hardware Page Tables
- Special Registers used by iOS
iOS Kernel Source Code
- Structure of the Kernel Source Code
- Where to look for Vulnerabilities
- Implementation of Mitigations
- MAC Policy Hooks, Sandbox, Entitlements, Code Signing
iOS Kernel Reversing
- Structure of the Kernel Binary
- Finding Important Structures
- Porting Symbols
- Closed Source Kernel Parts and How to analyze them
iOS Kernel Debugging
- Panic Dumps
- Using the KDP Kernel Debugger (hands on tasks limited to 30 pin devices)
- Extending the Kernel Debugger (KDP++)
- Debugging with own Patches
- Kernel Heap Debugging/Visualization (new software package)
iOS Kernel Heap
- In-Depth Explanation of How the Kernel Heap works (including all the changes in iOS 10.x)
- Different techniques to control the kernel heap layout (including non-public ones)
- About the heap randomness in iOS >= 9.2
- All the changes to the heap with iOS 10
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
- NEW Full walkthrough through exploitation of 10 prior known iOS memory corruption vulnerabilities
- NEW Overview over different vulnerability types commonly found in iOS kernel and exploit strategies
- NEW Part of the training will be to reimplement bits and pieces of an iOS 9.3.3 kernel exploit
iOS Kernel Jailbreaking
- NEW Full walkthrough through the Kernel Patch Protection as leaked by Apple
- NEW Discussion of all the Kernel Patches applied by recent iOS Jailbreaks
- Discussion of differences between 32 bit and 64 bit patches
Handling of New Devices
- Discussion of necessary steps to port exploits from old to new devices
- Persistence really required?
- NEW Overview of types of persistence exploits so far
- The topic of persistence or untethering will be discussed although the kernel land is only partially involved.
- This training course allows trainees to submit a list of topics they are missing from the list of topics and would like to see discussed. The most wanted topics of all attendees will be added to the course.
- Attendees of our trainings will now get a 9 months guarantee of updates: This means if another training of the same kind is held within 9 month of their booked training they will receive the updated training material free of charge (after the new training was held).
- All students will take home an iPod Touch 16GB (64 bit) with a retail value of now 229,- EUR (these iPods are jailbroken on iOS 9.x for the hands-on during the training).
- The whole training material (multiple hundred slides) will be handed to the students in digital form.
- In addition the training material of our previous course will be handed in digital form.
- Trainees will get a license for the Antid0te software and scripts that are used during the training that allows usage but not redistribution of said software.
- 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. There is a short refresher inside 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...
- About 3 weeks before the training trainees will receive a paper that covers introductory 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.
- Due to new EU export regulations on so called "Intrusion Software Technology" all exploitation trainings are subject to export control. This means we can currently only accept students from EU, Switzerland, USA, Canada, Japan, Norway, Lichtenstein, New Zealand, Australia.
- An Apple Mac Notebook is required in order to run OS X Yosemite and XCode.
- Training hands-on exercises will be performed on devices provided by Antid0te. It is not required for students to bring their own iOS devices.
- Every student will be handed an iPod Touch 16GB 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 Antid0te if required.
- Legal IDA Pro 6.x license (ARM64 support required) / Hopper use at own risk
- Hexrays for ARM helpful, but not required
- BinDiff for IDA helpful, but not required
- Mac OS X 10.11, with latest XCode and iOS 9.x SDK (or newer)
- Additional Software will be made available during the training
The training will be held at the RAMADA Hotel Berlin (Germany). The hotel is located near the Alexanderplatz in Berlin, which is easily reachable with public transportation from many parts of Berlin.
No special deal has been made with the hotel concerning rooms for the attendees. Attendees are free to choose whatever hotel is nearby.
|Early Bird (before 1st September)||3800,- EUR||722 EUR|
|Regular (before 4th November)||4000,- EUR||760,- EUR|
|Late (after 4th November)||4500,- EUR||855,- EUR|
The training ticket price include daily lunch, morning and afternoon coffee breaks, free soft drinks in the training room.
