Firmware rehosting enables firmware execution and dynamic analysis. Prior rehosting work has taken a “one-size-fitsall” approach, where expert knowledge is baked into a tool and then applied to all input firmware. Penguin takes a new, targetcentric approach, building a whole-system rehosting environment tailored to the specific firmware being analyzed. A rehosting environment is specified by a configuration file that represents a series of transformations applied to the emulation environment. The initial rehosting configuration is derived automatically from analyzing the filesystem of an extracted firmware image, providing target-specific values such as directories, pseudofiles, and NVRAM keys. This approach allows Penguin to rehost systems from a wide variety of vendors. In tests on 13,649 embedded Linux firmware images from 69 different vendors and 8 architectures, Penguin was able to build rehosting environments that work for 75% more firmware than the prior state of the art. We implement a configuration minimizer that finds required transformations and show that most firmware require only a small number of transformations, with variation across vendors.
