Interestingly enough, it may not even have been as complicated as that. According to one Reddit commenter, the UGA calendar is left wide open for submissions - and in some cases, posts may be under minimal (if any) review. So it may be that he simply found the wide open URL, filled out a form, and hit 'submit'. http://www.reddit.com/r/gatech/comments/2quflw/georgia_tech_student_indicted_for_uga_website_hack/cna5jjz http://www.reddit.com/r/gatech/comments/2quflw/georgia_tech_... Seems like that would be fair game without using Tor or some other proxy - since there are no terms or conditions of use mentioned on the form, seems like it's open to anyone to post. But who's to say?
