Google Publishes "Leaky.Page" Showing Spectre In Action Within Web Browsers

[Tolkem]

An article I just bumped into and thought of sharing here https://www.phoronix.com/scan.php?page=news_item&px=Google-Leaky.Page-Spectre
An excerpt:

Google's Leaky.Page code shows its possible to leak data at around 1kB/s when running their Chrome web browser on a Skylake CPU. The proof-of-concept code is catering to Intel Skylake CPUs while it should also work for other processors and browsers with minor modifications to the JavaScript. Google was also successful in running this Leaky.Page attack on Apple M1 ARM CPUs without any major changes.

When you get to this page there's an optical illusion. The memory layout section appears to have darker sections kinda round in nature. There's actually a name for that optical illusion but I've forgotten it. To make the dark shapes go away, cover part of the grid with your hand.
