SektionEins organisiert Ende April 2014 ein iOS Kernel Exploitation Training in Frankfurt.
After our successfull iOS 6 Kernel Exploitation training in September, we have decided to give another iOS Security and Exploitation Workshop in Frankfurt again. However we have adjusted the training material to changes made in iOS 7 and are still improving the material for this new designed course on the iOS kernel and its exploitation. It will take place in Frankfurt (Germany) at the end of April 2014, 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 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 iOS 7 that you discover in kernel land on your own.
Introduction (starting with old devices)
- How to handle a new Firmware
- How to set up your Mac and Device for Vuln Research/Exploit Development
- How to boot own Kernels
- How to patch own Code into the Kernel
- How to write Code for your iDevice
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
- Extending the Kernel Debugger (KDP++)
- Debugging with own Patches
- Kernel Heap Debugging/Visualization
iOS Kernel Heap
- In-Depth Explanation of How the Kernel Heap works (including recent changes in iOS 7)
- Different techniques to control the kernel heap layout
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 7.0.4
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 7.1 is unknown at the moment it is not possible to predict what changes there might be in the kernel. However we will incorporate all the information known about the iOS 7.1 kernel until the training into the material.
- 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 Mountain Lion 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).
