ez a css history hack egyébként zseniális.
Strangely enough there’s been a ton of things happening in the CSS history hacking world lately, and I thought I should recap some of the more important events of late. Firstly, Firefox 3.0 came out, and wow - it feels an awful lot like when Firefox 2.0 came out. A good chunk of my favorite plugins no longer work - Switch Proxy, Auto Copy, LocalRodeo (since ironically it doesn’t install over SSL - and btw, that was the only public tool protecting anyone from JS based intranet hacking that I am aware of) and, of course, Safe History. Why is that a problem? Well, if you were relying on it to protect your history, it’s no longer an option.
Now, if that’s not bad enough, Jeremiah Grossman pointed me to a page that attempts to calculate your gender based on a portion of your history. An interesting take on the usefulness of the old CSS history hack. How accurate it is is questionable, but realistically this is pretty good for a first generation tool that is virtually un-tuned.
Last but not least, I did a little looking into the ol’ about:config options in Firefox and landed on a few options that were noteworthy. Not the least of which is browser.visitedcolor which can be re-set to anything you’d like. That means if you are simply looking for the color of a typical viewed link, you may be deceived if this color has been modified. That is - unless, the attacker knows that the victim has visited something before (a previous page perhaps), and the attacker’s code verifies that against something they couldn’t have visited (a domain that isn’t up, for instance) to isolate what the real viewed color is. So that option, if you were considering it, wouldn’t work for a more advanced version of the code that checked for this kind of thing.
It’s a sad day for the old CSS history hacking security though. And please, please don’t tell me that you’ll just turn off JavaScript to protect yourself!
