IMHO, as a practitioner and an information assurance graduate student, simply put you broke the law. YouYou have accessed a network infrastructure that was not your own and you did so without the written permission of the company/corporation nor that of the ISP. You have a committed athe felonious act of a gray hat hacker. However, if you are truly concerned for the stability of the company site and infrastructure you could as another user has suggested...create, create a bogus e-mail and perhaps use the tor browser to communicate your concerns. Best of luck in your studies. I love the irony of you being an alleged cyber crime student while committing cyber crimes. ThereThere are YouTube videossources out there that demonstrate how to setup your own testing lab(s).
