But The Matrix Reloaded is winning praise from the net's computer experts and hackers because Trinity is seen using a free, popular scanning tool called Nmap.
Nmap, or Network Mapper, is used to remotely scan a computer or set of servers to find out what a target is doing and to see if it has any vulnerabilities or loopholes to exploit.
Writing about the scene, the author of Nmap, known as Fyodor, said he almost danced in the aisles of the cinema when he saw Trinity using his creation.

Fyodor wrote that the film makers seem to have changed the text output of Nmap to help it fit better on the display Trinity uses in the movie.
He also said that in the future the Matrix films depict, Nmap seems to run much faster than it does now.
Trinity goes on to use Nmap to reveal the existence of a vulnerability in computer she is targeting which she then exploits with another, fictional, program called SSHnuke.
