This blog is the second post in our Embedded Linux Device Security Research series. In the first post, Emulating Embedded Linux Applications with QEMU, we covered some commonly used tools and discussed using QEMU in user-mode to emulate a single binary. This post covers how to use QEMU in system mode to create a VM to emulate the target device. When emulating individual binaries doesn’t cut it, you can run QEMU in system mode to emulate an entire OS. From the previous post, we know that the D-Link DIR-866L is a MIPS device, so we will use the qemu-system-mips emulator….
