Security researchers have warned for many years that failure to digitally sign and validate the low-level firmware found in computers can lead to damaging compromises that are very hard to detect and fix. The identified devices included a network interface chipset widely used in servers, a common laptop WiFi adapter, a trackpad, a full HD camera and an internal USB hub. Researchers from security firm Eclypsium have found computer components with unsigned firmware or improper signature validation in laptops from major manufacturers, as well as in servers.”]
