Haven't seen that one, but the one I remember was from Matrix Reloaded.
Trinity used Nmap to scan for vulnerabilities and then used a SSH1 CRC32 attack, which was a real world loophole in computers back then.
And the tech world definitely noticed. There were a lot of discussions about how cool that was on blogs and forums back then. I think even Wired Magazine wrote about it.
It also showed that realistic hacking could make for interesting screen drama. Hacking a offside backup company by coming in for an interview and installing a trojaned wifi router.
