Miller also added that Firefox on Windows is easily the hardest of the three browsers to crack, despite Microsoft's claims that IE8 is "."

That may be literally true -- if you keep your hands at your sides and don't touch your keyboard or mouse, IE8 is probably pretty safe. Otherwise, well... you plays with Microsoft software, you takes your chances.

So where was Google Chrome in all this? Good question. Day three of the hacking contest (i.e., today) is supposed to focus on mobile platforms and Chrome. I'd be shocked if Google's browser proves impervious to the wily Nils or his nerdy cohorts.

Fact is, browser security is a relative concept. Your front door is secure, right up to the moment someone breaks into it. Then, not so much. But it helps to make sure it's made out of hardwood and not balsa, and there's a deadbolt or two on it.
