They link to "GPU.zip" which apparently is another side-channel based on the GPU's compressions - https://www.hertzbleed.com/gpu...

So apparently by asking it to blur the background, they can time it. Then the "core" of the attack is this GPU.zip so really it sounds like this is more of a "look we found a new way to exploit this."

FTA:

What Android APIs does Pixnapping exploit?

Pixnapping forces sensitive pixels into the rendering pipeline and overlays semi-transparent activities on top of those pixels via Android intents. To induce graphical operations on these pixels, our instantiations use Android’s window blur API. To measure rendering time, our instantiations use VSync callbacks. For a more detailed explanation, we refer to the paper.

Have you looked lately? I got my laptop last year and put Pop on it. Uses the 4070 out of the box and I was playing the second Horizon game on Steam on release day. The huge tons of effort put into getting AAA games running on the Steam Deck has really paid off. I'm currently playing Uncharted 4 on it.

I do still have two desktops running Windows, but finally migrated my daily driver laptop last Black Friday.

Comment What about COVID? (Score 2) 84

So if it is an eight-year study, that means it was also spans COVID-19.

One of the know side effects can be "brain fog."

I didn't see that in the preview, and IMHO would be a giant glaring mistake. I'd love to know who got it, what strain (the O.G. was definitely much more malicious), and how hard it hit them.

Wash, rinse, repeat.

I remember I inherited some code with all kinds of these hand-tuned SSE things, luckily guarded by ifdefs. Turned them off, and boom, my code was nearly 2X faster. Because SSE had gone the way of the dino, and the compiler was able to take the straight code and do better with newer/wider SIMD registers.

Hopefully AVX-512 will be around long enough to actually matter for them; however I have my doubts because I saw in other comments Intel is dropping support for it in some CPU families.
