Now, here is an interesting one. Gigabyte BRIX are very small computers, similar to Intel NUCs, that can be used to replace those bulky desktop towers. I am using Intel NUCs myself at the house and the office.
Well, these small devices have no hard disk and everything lives in different types of memory. At the BlackHat Asia 2017 security conference, researchers from cyber-security firm Cylance disclosed two vulnerabilities in the firmware of Gigabyte devices, which allow an attacker to write malicious content to the UEFI firmware.
