scottslayer On Linux, the researchers confirmed they could measure SSD latency from the browser, but didn’t run the full fingerprinting classification, and Windows wasn’t tested at all. Not good Reply
BillyBuerger Wait, browsers let any website to consume a huge amount of local disk space without any user approval? This sounds bad on its own. Reply
derekullo I'm assuming Optane wouldn't have this issue since it effectively has no variation in access time? https://cdn.mos.cms.futurecdn.net/WXcTLyrFcqp88UV5cQZg9G-1200-80.png.webp Reply
rluker5 If a browser is using 100% of my ram, then proceeds to fill up most of my OS drive so that if I were using NAND, it would be running slow for an SSD, that browser is getting closed before I even open the task manager because it is running like complete trash. I don't think most have recent experience trying to do things online when the page is running off of your hard drive. I have some old 2GB ram pc sticks and a tablet and running them off of a hard drive instead of ram is broken pc slow. Anyone will notice in short order if this exploit is being applied. And SSD performance varies significantly in latency depending on a decent number of factors. (brand, model, CPU+ PCIe characteristics, Windows power plan, Windows version with low latency mode, native NVME enablement, SSD temp, adblock enabled, browser and version used, etc.) How will they standardize for every scenario to know Toms, youtube video x, russian propaganda site or whatever else you are watching? Macs have very standardized hardware and controlled operating systems. DIY PCs aren't Macs and have way more variability be they running Windows or Linux. I'm more worried that MS will spy and sell my info than having some system performance trashing hack will slip by unnoticed. But putting a stop to "the Origin Private File System (OPFS), a browser API that lets websites create and store files on a user's local disk without prompting for permission." doesn't sound like a bad thing. And yes, my OS drive is Optane but that might also be hackable because it should be very consistent in how long it takes to read files. Good thing those drives are fairly rare. Reply

Notton I think the overlooked part here is "JavaScript" No one should run that, ever. Reply
