1nternal is a programmer and virus coder from Brisbane, Australia. He is best known as the creator of the first MS Office virus (one that can infect more than one type of Office file) Triplicate as well as one that can infect Office files, HTML and VBS files, Cross.


1nternal takes his name from a 2880 internal modem he was using during an IRC session.

One of his first viruses, Rat.848 was coded when he had no Internet connection and only a book on advanced assembly.
