Design and Implementation of a Universal Offline Reading System for Embedded Device Firmware

Obtaining firmware is one of the prerequisites for vulnerability analysis, mining, and verification. Web crawlers can obtain a large number of firmware, but may not be able to obtain the firmware of a specific device under test. If the embedded device can be obtained, the online reading or offline reading method can be used to read the firmware from the firmware memory. This paper designed a firmware offline reading and writing system for embedded devices. The key modules such as logic design, system structure, host computer, and socket interfaces are introduced in detail. Tests have been done to prove the correctness and effectiveness of the system.
