Reminds me of when I got thrown out of a "Security" class at my old job they made mandatory for all admins in the company to take. Some lady was up there trying to dazzle and astound by exploiting Windows RPC and DCOM, so I decided to screw with her a little since she was also using Windows
It was a similar type of "How to Hack" class and she worked for some local Microskills type school. They thought teaching the admins of the company how to "hack" would improve their awareness of security and they may learn what to do to defend against some stuff. Alas, the plan failed completely. Generally you cant teach or suggest anything to Microsoft Admins unless its printed in a Microsoft Press book or listed on the MS website.
I probably would have gotten away without anyone knowing it was me if I wasnt laughing so damn hard when I locked her out of her machine, hehe. That and the fat guy next to me ratted me out because he watched me the whole time.
