These OEM drivers are often decades old and coded without concern for their potential impact on the overall integrity of those systems.<
Many of these drivers come preloaded on devices or get silently dropped when installing some innocuous legitimate software bundle and their presence is entirely unknown to the users.
<Īs part of our commitment to secure the internet for all users, our researchers have engaged in an open - ended process of vulnerability discovery for targets that impact wide swaths of end users.Our research has been consistently fruitful, particularly in the area of OEM drivers[ <Ī href="https:/ / / cve - 2021 - 21551 - hundreds - of - millions - of - dell - computers - at - risk - due - to - multiple - bios - driver - privilege - escalation - flaws / " target=" _blank " rel=" noopener noreferrer ">#Malware years runonly applescripts to detection update#
