John Draper Information

John Thomas Draper (born 1943), also known as Captain Crunch, Crunch or Crunchman (after Cap'n Crunch, the mascot of a breakfast cereal), is an American computer programmer and former phone phreak. He is a legendary figure within the computer programming world.

Background

Draper is the son of a U.S. Air Force engineer; he described his father as distant in an interview published on the front page of the Jan 13–14, 2007 issue of The Wall Street Journal. Draper himself entered the Air Force in 1964, and while stationed in Alaska helped his fellow servicemen make free phone calls home by devising access to a local telephone switchboard. After Alaska, he was stationed at Charleston Air Force Station in Maine. In 1967, he created WKOS [W-"chaos"], a pirate station in nearby Dover-Foxcroft, but had to shut it down when a legitimate radio station, WDME, objected. He was honorably discharged from the Air Force in 1968 and did military-related work for several employers in the San Francisco Bay Area. He adopted the counterculture of the times and operated a pirate radio station out of a Volkswagen van.

Phreaking

While Draper was driving around his Volkswagen Microbus to test a pirate radio transmitter, he broadcast a telephone number to listeners as feedback to gauge his station’s reception. A callback from a “Denny” (identified in the Discovery Channel documentary about Hacking as Denny Teresi[1]) resulted in a meeting and caused him to blunder into the world of the phone phreaks. They wanted him to build a multifrequency tone generator (the blue box) to gain easier entry into the AT&T system, which was controlled by tones. Then they would not have to use an organ and cassette recordings of tones to get free calls. At least one of the blind boys called Joybubbles had perfect pitch and had identified the exact frequencies. They informed him that a toy whistle that was, at the time, packaged in boxes of Cap’n Crunch cereal could emit a tone at precisely 2600 hertz—the same frequency that was used by AT&T long lines to indicate that a trunk line was ready and available to route a new call.[2] This would effectively disconnect one end of the trunk, allowing the still connected side to enter an operator mode. Experimenting with this whistle inspired Draper to build blue boxes: electronic devices capable of reproducing other tones used by the phone company.

I don’t do that. I don’t do that anymore at all. And if I do it, I do it for one reason and one reason only. I’m learning about a system. The phone company is a System. A computer is a System, do you understand? If I do what I do, it is only to explore a system. Computers, systems, that’s my bag. The phone company is nothing but a computer. — Secrets of the Little Blue Box, Ron Rosenbaum, Esquire Magazine (October 1971)

The class of vulnerabilities Draper and others discovered was limited to call-routing switches that employed in-band signaling, whereas newer equipment relies almost exclusively on out-of-band signaling, the use of separate circuits to transmit voice and signals. Though they no longer serve a practical use, the Cap’n Crunch whistles did become valued collector’s items. Some hackers sometimes go by the handle “Captain Crunch” even today; 2600: The Hacker Quarterly is named after this whistle frequency.

The expense of sustaining the unbilled phone calls, the redesign of the line protocols, and the accelerated equipment replacement due to the blue box is difficult to calculate, or even to separate from something as complex and dynamic as the telephone long-distance network.

The 1971 Esquire article which told the world about phone phreaking got Draper in hot water. Draper was arrested on toll fraud charges in 1972 and sentenced to five years’ probation. The article also brought him to the attention of Steve Wozniak, who located Draper while working as an engineer at KKUP,[3] a Cupertino public radio station located near the future Apple campus. In the early and mid 1970s he taught his phone phreaking skills to Steve Jobs and Steve Wozniak, who later founded Apple Computer. He was briefly employed at Apple, and created a telephone interface board for the Apple II personal computer, which he named "The Charlie Board".[2] Wozniak has said the reason the board was never marketed was that Wozniak was the only one in the company who liked Draper,[4] and partially due to Draper's arrest and conviction for wire fraud. While at Apple, Draper also wrote a cross-assembler used by Steve Wozniak while developing Apple I and Apple II.[5]

Software developer

Draper wrote EasyWriter, the first word processor for the Apple II, in 1978. According to The Wall Street Journal, he hand-wrote the code while serving nights in the Alameda County Jail, then entered the code later into a computer.

Draper's personal website furnishes a more detailed version[6] of the coding of EasyWriter. Draper was in prison, in California, at the time, but under a 'work furlough' program. This meant that while he had to spend every night in prison, he spent each day working a regular job outside prison. This job was at Receiving Studios, a small band practice studio, and while there he had access to a computer, where he coded EasyWriter. He did take copies of the code 'home' to prison overnight to work on it.

Draper later ported EasyWriter to the IBM PC, beating Bill Gates on the bid for the IBM contract. Draper's company, Capn' Software, posted less than $1 million revenue over six years and he subsequently sued his software's distributor, Bill Baker, over an unauthorized version of EasyWriter that Baker released without Draper's permission – they settled out of court.

Draper's OCD-like behavior and creative mind has at times led to difficulties with potential clients who find him too encompassing of the original California software community ethos – which he sticks to until this very day. Shortly after Apple released Macintosh he taught an online course in Mac programming. Currently he writes computer security software, is a senior developer of KanTalk!, VoIP client built around singer and actress Lola Blanc (born Kandice Melonakos),[7] and hosts an internet TV show, Crunch TV.

From 2005 to 2010, Draper was the Chief Technical Officer (CTO) for media delivery company En2go, that delivers music, video and other digital content to desktops.[5]

In 2011 John joined the group Canadian Pirates Inc [8] with long time friend (Rod Thacker)[9].

Draper's software development history includes:

Legends

One oft-repeated story featuring Captain Crunch goes as follows: Draper picked up a public phone, then proceeded to “phreak” his call around the world. At no charge, he routed a call through different phone switches in countries such as Japan, Russia and England. Once he had set the call to go through dozens of countries, he dialed the number of the public phone next to him. A few minutes later, the phone next to him rang. Draper spoke into the first phone, and, after quite a few seconds, he heard his own voice very faintly on the other phone. He sometimes repeated this stunt at parties. Draper also claimed that he and a friend once placed a direct call to the White House during the Nixon administration, and after giving the operator President Nixon's secret code name of "Olympus", and asking to speak to the president about a national emergency, they were connected with someone who sounded like Richard Nixon; Draper’s friend told the man about a toilet paper shortage in Los Angeles, at which point the person on the other end of the line angrily asked them how they'd managed to get connected to him.[10] Draper was also a member of the Homebrew Computer Club.[2]
