Since there still seems to be a debate about exactly <i>what</i> weakness was exploited, that conclusion is unwarranted.<p>For that matter, a truly thorough cracker (with more time than constructiveness) might go to the trouble to identify <i>more than one</i> weak point, hold some in reserve, and exploit them sequentially over time - either to offer a more depressing experience to the site owner or to discredit the site's technical team [taking advantage of people willing to jump to your conclusion :) ]
