A report details a project in which the author reverse-engineered firmware on several consumer peripherals to document update formats and security properties. The devices examined include an Insta360 Link webcam, an ASUS monitor, a Shure MV7 microphone, an Elgato Cam Link 4K, and an Elgato Key Light Mini, with findings of minimal protections on firmware updates in several cases and one device employing signature verification but not boot-time secure boot. The work describes extracting firmware, analyzing update protocols, and demonstrating potential manipulation of device behavior such as LEDs and access to a plaintext command shell.
