New UEFI vulnerabilities send firmware devs industry wide scrambling
Enlarge (credit: Nadezhda Kozhedub) UEFI firmware from five of the leading suppliers contains vulnerabilities that allow attackers with a toehold in a user's network to infect connected devices with malware that runs at the firmware level. The vulnerabilities, which collectively have been dubbed PixieFail by the researchers who discovered them, pose a threat mostly to public and private data centers and possibly other enterprise settings. People with even minimal access to such a network—say a paying customer, a low-level employee, or an attacker who has already gained limited entry—can exploit the vulnerabilities to infect connected devices with a malicious UEFI.
