He first became famous when, as a student at Georgia Tech, he discovered a security flaw in the campus magnetic ID card system called "BuzzCard." He gave a talk about the security flaw at the Atlanta hacker conference "Interz0ne" in Fall 2002.

At Interz0ne2 in April 2003 he attempted to give an updated version of the talk with Virgil Griffith, a student from the University of Alabama, but he and Griffith were served with a cease and desist letter a few hours before giving the presentation, and then within two days this was followed up by a lawsuit from Blackboard Inc, alleging that Griffith and Hoffman had violated the DMCA, the Espionage and Sedition Act, and that they had stolen trade secrets. [cite news|first=Tim|last=Cailloux|url=http://nique.net/issues/2003-04-18/1|title=BuzzCard maker silences student|work=The Technique|date=2003-04-18|accessdate=2007-04-10] [cite news|first=Andrea L|last=Foster|url=http://chronicle.com/free/2003/04/2003041601t.htm|title=At Blackboard's Request, Judge Prevents Students From Discussing Security of Debit-Card System|work=The Chronicle of Higher Education|date=2003-04-16|accessdate=2007-04-10] The lawsuit was eventually settled.
