The UEFI firmware used by dozens of perating system (OS)models is susceptible to security flaws that permit the installation of bootkit malware, which is undetectable to the operating system and resistant to reinstallations.
The flaws might give attackers with local or remote administrator permissions the ability to run arbitrary code in System Management Mode (SMM), which is a separate environment from the operating system (OS) and grants them additional machine privileges.
At boot time, mechanisms with low-level hardware access that run code beneath the OS are activated. As a result, malware can get past the system’s conventional security measures in these settings.
The Secure Boot feature of UEFI, or Unified Extensible Firmware Interface, firmware makes it more secure by ensuring that a device boots up with a trustworthy read more about Gigabyte motherboards vulnerable to UEFI malware bypassing Secure Boot.
