Cookie Eviction

Jeremiah Grossman · blog.jeremiahgrossman.com

Identities harvested through browser auto-complete bugs can be pinned into a cookie before the bug is patched, then resold through a JSONP-style widget that any site can embed. As a counter, browsers cap total stored cookies (3,000 in Firefox, 3,500 in Chrome and Safari) and evict the oldest; 70 wildcard subdomains each setting 50 cookies hits the cap in seconds and wipes every domain's cookies.
