Lexicon

A field guide to the language of the three verticals: phreaking and security, electronic music, and the old weird internet. Not exhaustive, and growing. For virus-specific terms, see the museum glossary.

2

[SIG]2600 Hz
The in-band signaling tone AT&T used to mark a long distance trunk as idle. Whistle or play 2600 Hz into a call and the switch believes the line is free, handing you control of the trunk. The whole site is named after it.see also: Blue box, Phreaking

A

[MUS]Acid house
A genre built on the squelching, resonant sound of a misused TB-303, born in Chicago in the mid-1980s and central to the rave era.see also: TB-303
[MUS]Ambient
Music that prioritizes atmosphere and texture over rhythm and melody, meant to be as ignorable as it is listenable, a term Brian Eno made explicit.
[STA]ANSI art
Text-mode artwork made from the extended character set and color codes of the IBM PC, used to give BBSes their login screens and identity.see also: BBS

B

[STA]BBS
A bulletin board system, a computer you dialed into directly over the phone line to read messages, trade files, and play games. The social internet before the internet.see also: ANSI art, The scene (warez)
[SIG]Black box
A circuit wired into your own phone line that manipulates its voltage so incoming long distance calls register as never answered, making them free for the person calling you.see also: Blue box
[SIG]Blue box
A device that generates the full set of multi-frequency tones AT&T used to route calls, letting a phreak place free long distance calls and dial anywhere. Wozniak and Jobs sold them before they built Apple.see also: 2600 Hz, Red box, MF (multi-frequency)

C

[STA]Cracktro
A small animated intro a cracking group attaches to pirated software to sign their work, with scrolling text, music, and effects. A direct cousin of the demoscene.see also: The scene (warez), Demoscene

D

[STA]Demoscene
A subculture that writes programs to generate real-time audiovisual demos, pushing hardware to its limits purely to show off craft. It grew straight out of the cracking scene.see also: Cracktro
[SIG]DTMF
Dual-tone multi-frequency, the touch-tone system where each key on a phone plays two frequencies at once. It is the sound you hear when you dial.see also: MF (multi-frequency)
[MUS]Dub techno
A minimal, echo-soaked strain of techno that runs chords through long delays and reverb, defined by Berlin's Basic Channel in the early 1990s.
[SIG]DXing
The hobby of tuning in distant or hard to catch radio signals for the sport of it. DXers were the ones who first logged and cataloged numbers stations.see also: Numbers station

H

[MUS]Hauntology
An aesthetic of nostalgia for futures that never arrived, built from the textures of old library music, public broadcasts, and decayed tape. Ghost Box and Boards of Canada are touchstones.

I

[MUS]IDM
Intelligent dance music, a slightly awkward label for the experimental electronic music tied to Warp Records and artists like Aphex Twin and Autechre.see also: Spectrogram
[STA]IRC
Internet Relay Chat, the real-time text chat protocol from 1988 that hosted everything from hacker channels to open source projects to file trading.

M

[SIG]MF (multi-frequency)
The pairs of audio tones telephone switches used to signal each other and route calls, including the KP (key pulse) and ST (start) markers. A blue box speaks MF.see also: Blue box, DTMF
[MUS]Musique concrete
A compositional approach that builds music from recorded real-world sounds manipulated on tape, rather than from notes played on instruments. A direct ancestor of sampling.see also: Oramics

N

[SIG]Numbers station
A shortwave radio station that broadcasts cryptic sequences of spoken numbers, used by intelligence agencies to send one-way messages to agents who decode them with a one-time pad.see also: One-time pad, DXing

O

[SIG]One-time pad
An encryption method that is mathematically unbreakable when used correctly: a truly random key, as long as the message, used exactly once. The only catch is sharing and protecting the key.see also: Numbers station
[MUS]Oramics
Daphne Oram's technique and machine for making sound by drawing shapes onto strips of film, turning a visual gesture directly into tone.see also: Musique concrete

P

[SIG]Phreaking
Exploring and manipulating telephone systems, the practice that predates and shaped computer hacking. Phreakers treated the network as a thing to be understood and bent, usually through sound.see also: 2600 Hz, Blue box

R

[SIG]Red box
A device that mimics the tones a payphone sends when you drop coins, fooling the system into registering money that was never deposited. Bernie S went to prison over one.see also: Blue box
[STA]RFC
Request for Comments, the document series that defines how the internet works. The humility of the name is the point: standards proposed in the open, for comment.

S

[SIG]Social engineering
Manipulating people rather than machines to gain access or information, through impersonation, pretext, or plain confidence. Often the easiest exploit in any system.
[MUS]Spectrogram
A visual plot of a sound's frequencies over time. Aphex Twin famously hid images, including his own face, that appear only when a track is viewed as a spectrogram.see also: IDM

T

[MUS]TB-303
A Roland bass synthesizer from 1981, sold to replace a bass guitarist and considered a failure. Producers misused its squelching filter into the sound of acid house.see also: Acid house, TR-808
[STA]The scene (warez)
The competitive underground that cracks and distributes copyrighted software, racing to be first to release. Its calling cards are the cracktro and the NFO file.see also: Cracktro, BBS
[MUS]TR-808
A Roland drum machine whose unrealistic analog sounds, especially its booming kick, became the backbone of hip-hop, electro, and dance music.see also: TB-303

U

[STA]Usenet
A distributed discussion system organized into newsgroups, predating the web and home to decades of technical argument, culture, and the original meaning of 'spam'.

W

[SIG]War dialing
Automatically dialing large ranges of phone numbers to find the ones answered by modems, fax machines, or other systems worth probing. Named after the film WarGames.see also: Phreaking
[STA]Webring
A circle of independent websites linked one to the next, so a visitor could travel a whole community by clicking 'next'. The pre-algorithm way to find related sites.
[MUS]White label
A vinyl record pressed with a blank or plain label, used to test or promote a track on the strength of the music alone, before any artwork or hype.

Z

[SIG]Zero-day
A software vulnerability unknown to the vendor, so there have been zero days to patch it. Zero-day exploits are valuable precisely because no defense exists yet.
