FirmGuide

FirmGuide can help you to develop a QEMU virtual machine for a Linux-based embedded system, especially boosting the capability of dynamic analysis of the corresponding Linux kernel. In the emulator, you can debug, trace, and test the Linux kernel to collect runtime information that can be used to understand vulnerabilities, PoCs, root causes of crashes in the Linux kernel. FirmGuide is an effectively complementary to Firmadyne that focuses on user space programs - FirmGuide focuses on the Linux kernel. More details are in our paper.
