Nmap is just the tip of the iceberg.

Over the years the most famous hacking tool  that has made it into the movies is Nmap. When producers of a movie actually try to put a dose of reality into the computer hacking scenes Nmap will often flash up on the screen. AFAIK Trinity was the first in the Matrix. Nmap has also appeared in Elysium, The Bourne Ultimatum, Die Hard 4 and many others.
