It should be noted that if a hacker is able to exploit this, they'd need a lot of access and you'd already be boned. This is no where as bad as what Intel is going through right now.

Saying that you have to "basically throw away your computer" is very misleading to say especially in a subtitle, when that exact thing is actually what is happening with Intel CPUs.

They say it's "Platform secure boot" by AMD. They refuse to elaborate further though, and no one knows wth that is. Except AMD themselves ofc: https://www.amd.com/en/products/processors/technologies/pro-technologies.html

Platform secure boot is designed to provide protection in response to growing firmware-level remote attacks being seen across the industry. AMD Secure Boot helps continue the chain of trust from the system BIOS to the OS Bootloader.

Ah fuck it, here's the security researchers explanation: https://labs.ioactive.com/2024/02/exploring-amd-platform-secure-boot.html?m=1

It's an exploit path to a UEFI bootkit, so at the very least you'd have to throw your motherboard away or find someone that can physically overwrite it through an external flash programmer or something. And the patch should be delivered through a UEFI firmware update, so if your motherboard is no longer supported you would have to buy a new one. And for laptops and embedded devices having everything soldered in, the motherboard is basically the whole computer, so I don't think it's that much of an exaggeration.

Man Intel really is paying off a lot of journalists to smear AMD while they are dealing with their rotting chips right now

Why is this downvoted? Isn't ArsTechnica a trusted tech news site? It is not controversial even if it has a neolib/neocon leaning -I can never tell the two apart-.

I can never understand why people would downvote someone sharing a news story.

Assholes, they won't fix Ryzen 3000s even if they still sell them - just bought a brand new boxed 3400g

After reading that whole article I feel no more enlightened.

They mentioned secure boot, is secure boot part of the exploit or does the exploit invalidate secure boot?

Because if I understood it right, it will be presented at DEFCON tomorrow, this news are just hyping it.

We don't know what is the install vector, it might be a non issue (for regular people) where you need a custom chip programmer and hands on the hardware

The wired article mentions kernel access to be sufficient.
