Shambles is a complete reverse engineering platform for embedded system and Internet of Things (IoT). With Shambles, the standard approach of hardware hacking is evolved from binwalk-reliant and IDA-oriented processes into a new dimension, which is not only precisely targeted to the multitude of embedded architecture, but also automate the reverse engineering process in enabling a mass quantity of firmware to be thoroughly analyzed on time. As a precisely embedded targeted reverse engineering toolset, with revolutionary core technology in static and dynamic analysis, intermediate representation, symbolic execution, emulation, and fuzzing, Shambles offer various of unique features for embedded system and IoT security evaluation. On the other hand, by harnessing the automated feature of Shambles, the entire security evaluation process is not only can be completed by using default template of patterns, but also possible to compile a new customized pattern in establishing more targeted evaluation for advanced user.
