Matrix Reloaded, the first major motion picture to accurately portray a hack. See pics at Insecure.org. Trinity uses an SSHv1 exploit to get #. Cool! Timeline discussion:

Not only is it important for the coolness factor, but we can learn how Nmap looks in the future by studying that output!
Maybe not. In the first movie, the Matrix world is in 1999. Morpheus mentions how since Neo became the One, they have "freed more minds in the past six months than the past six years". So Trinity is actually using an exploit discovered in 2001, in a simulated world that can be no later than June 2000. So how can she do this? Possibilities. * Trinity is one of the best hackers on the planet. She could have discovered the flaw herself, or perhaps some other Zion-based hacker did. * In the real world, they do have some technology from earlier eras. Perhaps Trinity came across some old mailing lists on a CDROM. Say hi to her next time you post.
