Submission + - What the Internet knows about you 1

leromarinvit writes: LWN just posted a story about an interesting new privacy threat: What the Internet knows about you is a site which uses CSS (and optionally JavaScript) to find out which sites you've recently visited.

A new site at is an interesting demonstration of CSS-related browser history disclosure vulnerabilities. This site is able to produce a surprisingly comprehensive list of sites that one has visited, down to the level of specific pages on social networking sites and such. No JavaScript required. There's also information on just how the site works and how the disclosure of information can be minimized. "It is a source of amazement to us that such an obvious and well-documented history sniffing channel has been allowed to exist for so many years. We cannot help but wonder why, despite all the malicious potential, such a hole has not yet been closed."

The site is already slow without even being slashdotted, so be gentle with it.
