IIRC, the group was called the Praetorians.

What's ultimately scary about it, though, was that despite being limited by the 1990s technology, the plot of the movie fits neatly into today's world, where the "backdoor" ends up in so many systems that can affect your life:
-- pharmacy & medical records (character was killed when his prescription was changed to a medication he was allergic to, then when admitted to the hospital he was administered the wrong medication)
-- BMV (her driver's license record is switched with one of the group's members)
-- aircraft systems (person's navigation system in his light plane takes him off course, & he crashes into a power plant)

Just to name a few. Scary how much her life was initially ruined just by the manipulation of a few megabytes of data...
