FirmProj: Detecting Firmware Leakage in IoT Update Processes via Companion App Analysis
This program is tentative and subject to change.
The rapid growth of the Internet of Things (IoT) has led to the widespread use of companion apps for device management. However, these apps expose a critical vulnerability in the IoT ecosystem: insufficient verification procedures during device firmware updates (DFU), often resulting in firmware leakage. Once leaked, the firmware reveals sensitive design details, creating a straightforward path for attackers to reverse-engineer devices. To address this issue, we designed an automated analysis tool called FirmProj. It systematically evaluates firmware leakage risks by examining IoT companion apps. FirmProj combines advanced static analysis techniques with large language models to identify DFU modules, extract firmware files, and detect security vulnerabilities. In a large-scale study involving 10,047 IoT companion apps, FirmProj successfully retrieved 3,434 firmware files, uncovering severe flaws in DFU implementations that can lead to firmware leakage. These findings resulted in the assignment of 35 CVE IDs. Our results highlight the urgent need to strengthen firmware protection mechanisms throughout the IoT ecosystem.
