Browser Fingerprinting via Favicons: Persistent Tracking Method Called Supercookie
By
vxvrs
A baker's-dozen of insight crammed into one ring.
Summary
Supercookie is a browser fingerprinting technique that uses favicons to assign persistent unique identifiers to website visitors. Unlike traditional tracking methods, this ID can be stored almost permanently and cannot be easily cleared by users. The tracking works even in incognito mode, survives cache clearing, browser/OS restarts, VPN usage, and ad blockers. The repository is presented as educational/demonstration material to raise awareness about this privacy vulnerability.
