The Road to iOS Sandbox Escape

Explore the intricacies of iOS sandbox escape techniques in this HITB Security Conference talk. Delve into the world of mach message IPC and poorly designed daemons, uncovering vulnerabilities that allow arbitrary code execution outside the sandbox. Learn about research tools for analyzing mach message handlers and gain insights into exploiting vulnerabilities across various iOS daemons. Discover the potential for full chain exploitation and necessary gadgets. Understand the challenges of iOS research, explore IDA techniques, and witness demonstrations of sandbox escape methods. Examine specific vulnerabilities in Bluetooth functionality, including pair device retrieval and session token manipulation. Gain valuable knowledge about iOS security, jailbreaking, and cutting-edge mobile device exploitation techniques.
