PC Motherboards Sold with Firmware Backdoor

Researchers at cybersecurity firm Eclypsium have discovered a hidden mechanism in the firmware of motherboards sold by Taiwanese manufacturer Gigabyte, which could allow hackers to install malware. The mechanism is meant to keep the motherboard's firmware updated, but is implemented insecurely, potentially allowing it to be hijacked. The updater program is triggered from the computer's firmware, making it difficult for users to remove or detect. Eclypsium lists 271 models of Gigabyte motherboards that are affected.
