Peripheral devices with unsigned firmware can expose Windows and Linux machines to attacks, allowing hackers to install stealthy and persistent malware, steal valuable information, or take control of a computer.
Researchers at firmware security company Eclypsium have discovered that many peripheral device manufacturers have not implemented checks to ensure that the firmware running on their products comes from a trusted source.
Attacks can be launched against both Windows and Linux computers, including laptops and servers.
Eclypsium has identified insecure firmware on touchpad and TrackPoint firmware used in Lenovo laptops, the HP Wide Vision FHD camera on an HP laptop, the WiFi adapter on a Dell XPS laptop, and a VLI USB hub.
Installing malicious firmware on these types of devices can often be done by abusing legitimate firmware update tools.
