Over the last few days, thousands of computers at Stanford have been hacked because they were not updated. Recent widespread attacks exploited a Microsoft Windows security vulnerability that has been public since July 16th (henceforth referred to as "the hole"). Once compromised, the hacker has full access to your computer and files, and could potentially do anything you could while sitting at it. This includes deleting your files, or attacking other computers.
