Menard is one of hundreds of aliases used by Harry Maybourne. When O'Neill arranged his temporary release from prison in order to gain evidence against rogue elements within the NID, Maybourne used a safehouse and firewall protected floating server with decoding software to make contact with NID cells. Through the Findorama.net bulletin board, he attempted to enter the username "Menard" and a 6-letter password, however his password had been deactivated.
