Realistically a good starting point to read up on could be about admin privileges. Or ring 0 in software. It basically boils down to the fact that anything that is running as root ( or with admin privileges) can read and write to ANY file it wants to. Effectively having full control over the system.
In other words it could be used to do anything they want with your pc. An example of that actually happening is the anti Cheat that genshin impact is using because that was exploited in that way already.
Do you have some further reading on the active exploit of Genshin Impact's anti-cheat?
I know about ring 0, I just assumed UEFI would be off the disk and inaccessible to any software.
UEFI is off disk, but it is writeable to some degree.
Recently there was a story about a hack exploiting the ability to write boot images (as in vendor screens that display during boot).
There's also the ability to store executable code that runs even if the system doesn't have an OS - this is ostensibly used for theft prevention solutions. Just imagine how that can be abused.
UEFI is a ******* problem. I've never liked it. I get why it exists, but it's design was intentionally borked to push DRM-like control, under the guise of offering increased security. Yet we have that boot code that can be executed silently.
It would be nice to see the 80's BIOS wars again, with an open-source UEFI organization this time.
