Unified Extensible Firmware Interface (UEFI) is an interface layer between operating system and firmware. UEFI is an open standard intended to make it harder for bad people to manipulate firmware in an unauthorized manner. The latest version adds what’s called secure boot, which requires a unique key for each computer and each OS or low-level application. It’s far easier to write malware that can brick your computer than the code contained in the average Trojan horse, worm, or virus. A growing number of attackers with a variety of agendas may use bricking as a weapon against all sorts of targets.”]
