Kernel exploitation on Android devices still presents a relatively new unexplored research area due to its diverse range of hardware options and hardware/software exploitation mitigations implemented by vendors or the Linux kernel itself. Similar to other operating systems, Android provides several common user-space exploitation mitigations and attacking the kernel is an appealing option to obtain full access on the device bypassing any user-space exploitation mitigations.
Vitaly is a security researcher at DUASYNT specializing in reverse engineering and exploit development. He has a solid academic background in programming languages, code analysis and algorithms. His current area of research is mobile security/operating systems (kernel space exploitation techniques and countermeasures).
This course starts by enumerating the Android kernel attack surface (from an LPE perspective) describing any sandboxing options that may limit this attack surface. Though the course is mostly self-contained and there’s a brief refresher on arm64 architecture, attendees should be already familiar with this architecture / instruction set.
The main focus is on common kernel vulnerability classes and exploitation techniques on Android. The training is hands-on and assumes some familiarity with Linux kernel exploit development. All practical labs / exercises will be performed on Pixel 4a devices. Common hardware/software kernel exploitation mitigations on Google and Samsung devices will be discussed and several bypass techniques will be presented. The course will also provide some introduction to fuzzing and crash analysis on Android devices.
This course is largely self-contained but please ensure you meet the entry requirements detailed below.
