Writing 1 gigabyte of data via browser"s javascript to a SSD to fingerprint users? Meh.

"Unlike previous contention side-channel attacks on SSDs, FROST runs exclusively in the browser. It uses JavaScript that interacts with the OPFS (origin private file system), an allocated storage space that’s reserved for a specific site to run code needed to complete a given task. Websites can create one with no interaction required by the visitor." #frost #websec #fingerprint #Security #opfs

WTF!?!! Why do the web providers always want to listen to their users instead of simply offering correct honest services?

Nice trick to still run #sqlite #wasm in browser with #opfs enabled if you can't set #coep / #coop on server

Who here knows enough #webplatfrom and #webapi to know if relative links exists with the Origin Private File System (#OPFS)?

thanks much for RT and dig to find people knowing...
