Spyjax – did you know your browser history IS NOT private???
(It was only a matter of time before someone figured out how to do this)
Ajaxian has just post about Spyjax a tool that can search your browser history. It works by using javascript to check if you have visited a site by analysing CSS colours!
“It only allows a site to test a predefined list of URLs to see if you have visited any of them. It’s like the card game “go fish”, you can’t see the players cards but you can ask them if they have any particular card. Most likely the way this technology would be used is to examine a list of competing URLs.”
I wonder how long spam marketers and blackhat seo’s have been using this technique???
So how to do stop it ???
Turn off javscript (This is bad no more ajax goodness) or in Firefox uncheck the “Remember visited pages” checkbox (This is also a pain as you’ll lose the autosuggestion of all your visited sites.)
