TaiE: Function Identification for Monolithic Firmware
Jintao Huang, Kai Yang, Gaosheng Wang, Zhiqiang Shi, Shichao Lv, Limin Sun · 2024
The principal tasks of program analysis, including bug searching and code similarity detection, are executed at the function level. However, the accurate identification of functions within stripped binary files poses a significant challenge. This difficulty is exacerbated by unformatted monolithic firmware images typically found in industrial controlling device, rendering existing methods ineffective due to their dependence on specific metadata, which may be absent.
