abilities in modern Android smartphones that are still viable, despite the mitigations in place.
In the first phase of this talk, we will discuss analysis and exploitation of vendor-customised versions of Android's Recovery mode, demonstrating weaknesses that allow for privilege escalation to root, and traversal from Recovery to Android, without Bootloader access, using nothing but a Micro SD card.
In the second phase, we will discuss weaknesses in the Secondary Bootloader of devices produced by a popular smartphone manufacturer. We will demonstrate how, using a vulnerability in the core USB stack, code execution can be achieved, and a modified Android image can be booted, without compromising the functionality of the device.
