Embedded kernel emulation in QEMU for security assessment | Stephane Duverger | hardwear.io webinar 2021
Abstract:
---------------
With the wide range of available methods and tools to discover vulnerabilities in embedded OS kernels, are QEMU internals still worth the investment to support emulation of a target firmware/kernel? We give our experience return on deep-diving into QEMU, implementing proprietary devices and starting booting a target OS until a point where security evaluation could begin. Thanks to the introspection power offered by such a simulation environment, fuzzing, memory analysis, scheduling properties, race conditions and so on can "easily" be explored.
