Res Timing Attack

ha.ckers.org web application security lab

David Byrne's twist on Billy Rios's res:// local file enumeration: instead of reading the result, time it. The CPU cost of resolving a res:// resource differs sharply by whether the file exists, over double on RSnake's machine, so existence leaks through timing alone. A demo page is linked.
