Mit der Technik #FROST können Websites über #JavaScript die #SSD-Aktivität von Besuchern analysieren und so offene Tabs oder Apps erkennen.

Grundlage ist ein sogenannter #SideChannel, der Zeitunterschiede bei Speicherzugriffen im #Browser misst. Dafür wird das Origin Private File System genutzt.

Die Methode gilt als komplex, zeigt aber neue Risiken für den #Datenschutz. Browserhersteller prüfen Gegenmaßnahmen.

Random thought...

I feel like a #Pcie5 #NVME #SSD could be worth the investment, just for the #OperatingSystem (be it #Linux and its Libraries/Swap or #Windows) and other main-load programs like #Steam and #Firefox (or another #WebBrowser), but the cheapest ones are nearly $200 and they're all at least 1TB... I wonder if we will see cheaper quarter-TB ones in the next couple years, because that feels like it'd be a good way to utilize the PCIe5 NVME slot in my fancy motherboard...

...or I could be wrong: it has been pointed out that PCIe5 drive speeds are mainly only useful for sequential reads, as lookup times create latency comparable to PCIe4, and that makes up the majority of read-time for smaller files. Maybe that can be improved? Maybe Linux distros will implement something that makes core libs load as big blocks? Or we'll have a way to speed up common lookups on the #OS side?

If possible, it'd be good for keeping current-gen #computers relevant over the next decade.

Web browsers can spy on information via SSD access times

IT researchers have demonstrated a side-channel attack called "FROST" where browsers can spy on user behavior via SSD access times.

Webbrowser können Informationen durch SSD-Zugriffszeiten ausspähen

IT-Forscher haben mit „FROST“ einen Seitenkanalangriff demonstriert, bei dem Browser über SSD-Zugriffszeiten Informationen über das Nutzerverhalten ausspähen.
