I just came across something which marcan42 (of fail0verflow / PS4 Linux fame) wrote a few weeks back:

The Evil Maid attack would need to be modified somewhat. For example, switching boot order to boot from SD card which is inserted by the attacker. You...

I was specifically referring to the "all bets are off" remark. If you boot a Chromebook and it does not give you the developer mode warning,...

Both LUKS full-disk encryption and /home encryption are susceptible to this problem. Neither is resistant against "Evil Maid" style attacks....

Michael
Do you have tests planned how AES-based LUKS compares against Google's new Adiantum encryption? That would be interesting, especially with...

When it comes to the proprietary AMDGPU-PRO driver, AMD cares basically about three distros: Red Hat Enterprise, SUSE Linux Enterprise, Ubuntu.

USB has a much better security record in that regard. Unsurprisingly, as the attack surface of USB is pretty small anyway.

No. The system...

Actually, this seems like a minimal-effort dumping of excess Stoney Ridge inventory. That CPU is from 2016, so three years old now. And did you read the...

If you want to get your hands on one, I suggest finding contacts at the places where owners/sellers of these would hang out. such as http://bbs.china...

All PCIe devices can provide a PCI Option ROM which in turn can be used to mount an early boot attack....

China to the rescue again? There are Alpha CPUs still made by Sunway (ShenWei), the SW1600. Those cannot be bought as easily on Aliexpress, but surely...

Adding to that, their proprietary network driver used to be a shitshow, nobody wanted to use it once forcedeth was developed....

And some hardware that could run Vulkan but is unsupported by current drivers. I remember airlied talking about Vulkan support for VLIW4 chips.

Loongson mobos for desktops/servers are readily available on Aliexpress. Dual-socket Loongson 3A quad-core will cost you about 400 USD....

microcode I'm not that optimistic. With Thunderbolt you depend on the correct implementation of the IOMMU in hardware, firmware and operating system drivers....

That probably means that Kepler will never see support for the new allocator library for Wayland in the proprietary drivers. So supporting NVidia proprietary...

A post in the previous FreeSync thread noted similar issues on an Acer Nitro 5 (works on Windows, doesn't work on Linux). In the end, the EDID had to...

In theory, an IOMMU should prevent DMA based attacks. In practice, they often fall short, due to buggy implementations in hardware, firmware and operating...

Some features are disabled / unsupported on Threadripper.

• SME / SEV

A successor to the Pinebook is planned to be released this year, the Pinebook Pro. It will have a 14" 1080p screen, a RK3399 6-core SoC with Mali...
