Eclypsium researchers Jesse Michael and Mickey Shkatov to share their work on "BadCam - Now Weaponizing Linux Webcams." Eclypsium researchers disclosed “BadCam,” a set of vulnerabilities in certain Lenovo USB webcams that run Linux and do not validate firmware signatures, allowing attackers to reflash the devices and turn them into BadUSB-style tools.

An adversary who supplies a backdoored camera or who gains remote code execution on a host can weaponize the webcam to emulate human-interface devices, inject keystrokes, deliver payloads, and maintain persistence — even re-infecting systems after OS reinstalls. The findings were presented at DEF CON 2025, Lenovo issued updated firmware/tools in coordination with SigmaStar, and researchers warn the same vector could affect other Linux-based USB peripherals, underscoring the need for firmware signing and stronger device attestation.
