Millions of computers are at risk due to a security vulnerability in GIGABYTE motherboards

Millions of computers are at risk due to a vulnerability in Gigabyte motherboards. The company has a serious security issue in the firmware of more than 240 motherboard models. This vulnerability could allow a hacker to infect your computer with malware, which will persist even after you reinstall the operating system.

According to Bleeping Computer, researchers at security firm Binarly discovered four critical flaws affecting millions of users using Gigabyte motherboards. Experts say the vulnerabilities in the firmware could allow an attacker to write data to SMRAM, a more privileged environment isolated from the operating system.

If a hacker manages to infect your computer with a malicious bootkit, the malicious code will remain in the UEFI firmware. The malware will run when your computer boots and can load other types of Trojans or spyware undetected. Due to its nature, the bootkit can survive a PC format and can bypass other security mechanisms, such as secure boot or memory isolation for virtual administrators.

According to the report, Binarly analysts reported the vulnerabilities to the Carnegie Mellon University Computer Emergency Response Center in April, and Gigabyte confirmed the flaw in June. However, the company did not issue any warning bulletins to its users until the issue became public.

So far, more than 240 motherboard models have been affected, primarily Intel 100- to 500-series chipsets. Some devices have updates available, but others have reached the end of their lifespan and are no longer receiving security patches.

In a post on its support website , the manufacturer stated that the vulnerabilities affect older motherboard models from the GIGABYTE and AORUS lineups. If you purchased an Intel motherboard between 2017 and 2021 and never updated its BIOS, you may be at risk.
