Filejacking: How to make a file server from your browser (with HTML5 of course)

WebKit's directory upload control lets a page read a whole folder, and users get no warning that a folder picker is not a save dialog. Kotowicz hid a transparent directory input over a fake download button, then opened a second window that survived the first being closed, uploaded the file listing and a sample image, and polled a control panel for further file requests.
