_UNAUTHORIZED ACCESS_
British documentary on hackers made by Savage Productions and directed by Annaliza Savage

THE UNDERGROUND
Referred to by some Netizens as the illegal or quasilegal community that forms in Cyberspace; includes hackers, phreaks, virus authors and warez d00dz; I often refer to the Underground more specifically as the Hacker Nation

UNIX
Operating system made by AT&T in 1969 of which several variants exist, such as Berkeley UNIX. Made by programmers, for programmers. It was purchased by Novell fairly recently. It also supposedly has very little security. The perfect hacker OS, or at least that’s what I hear; I haven’t had very many chances to use it. Maybe when AIX is ported to PPCP... [The name is a play off of Multics, its precursor OS; supposedly UNIX would unify the previous Multics, which was apparently a mess.]

UNKNOWN USER
Handle sometimes used on Phrack when a famous writer wished to write anonymously; came from the old name that appeared on Metal Shop BBS when someone posted anonymously

UPLOAD
To transfer via modem a program or file from a computer to a network, BBS or ftp site

URVILE
Also known as Necron 99. One of the Atlanta Three, imprisoned for activities with the Atlanta LOD. [Handle is from a Stephen R. Donaldson trilogy.]

UNITED STATES DEPARTMENT OF INJUSTICE
The hacked version of the US Department of Justice web site; hackers altered it to include lots of anti-CDA propaganda, swastikas, and "obscene pictures." Whoever those guys were have my eternal gratitude

UNITED STATES SECRET SERVICE [USSS]
Federal agency maintained by the treasury, formed in 1865, that protects the president, visiting dignitaries and a shitload of other stuff. Starting protecting the president in 1881. They (along with the FBI) are also in charge of computer crime, because of electronic funds. (Remember, they’re run by the treasury, so they protect dead presidents as well as live ones.)
