In an article from The Register, we find out how leet Trinity from the Matrix movies truly is.

So you understand what I am talking about I will quote an excerpt from the article:

"In a sequence that flashes on screen for a few scant seconds, the green phosphor text of Trinity's computer clearly shows Nmap being run against the IP address 10.2.2.2, and finding an open port number 22, correctly identified as the SSH service used to log into computers remotely. "

I use nmap on an almost daily basis to test for various things on my network. Its a great tool even beyond its hacking potential.

UPDATE: some sites were confused as to why there is an open exploit in SSH in the 2100's, the answer is quite simple... If your watching your timelines, she uses this sploit in the year 2000 while in the matrix.
