Hypervisor-Assisted Ring0 Debugging with Radare2
Explore hypervisor-assisted Ring0 debugging techniques using radare2 in this 44-minute conference talk from 44CON 2017. Delve into the challenges of reverse engineering protected kernel-mode code and learn how to overcome advanced protection mechanisms that combine obfuscation, encryption, and anti-debugging techniques. Discover how to leverage radare2's comprehensive open-source framework for reverse engineering, including its ASCII art control flow graphs and extensive code analysis capabilities. Follow along as the speaker demonstrates connecting radare2 to a virtual machine, enabling direct access to guest physical memory for debugging Ring0 code running inside a Windows guest from a Linux host. Gain insights into the GDB protocol, memory mapping processes, and debugging techniques for kernel-mode memory. By the end of this talk, acquire valuable knowledge on advanced reverse engineering methodologies and practical applications of hypervisor-assisted debugging for protected code analysis. Read more
