WebKit Hack. FillDisk localStorage Flaw.
So, someone shared a link today on facebook to filldisk.com. This uses the localStorage within HTML which just fills the users disk space using a flaw within the local storage code. My chrome simply crashed (i5-2410M 2.3GHz, 6GB ram, Win7 64bit) in incognito obviously. You can read more about it here: http://feross.org/fill-disk/
