Instead, they used it to disrupt businesses, harass government offices, and otherwise make mischief. The further the technology spread, the more it was utilized by “newbies” or folks who were unaware of the original gentlemanly culture of phreaking.

However, when using the Crunch whistle, the other end of the trunk was kept open, and the person on that end of the line was now considered by the equipment to be an official telephone company operator, meaning they could call anywhere free of charge.ĭraper and his good pal Steve Wozniak used this technology to build Blue Boxes, which could generate a variety of tones that would further manipulate Ma Bell’s intricate web of phone lines. Blue Boxing led to Black Boxing, Beige Boxing and other permutations of phone trickery gadgets. When Bell’s equipment “heard” the 2600Hz sound, it was the signal that the call had been terminated, and one end of the trunk line was closed.

Once a long-distance call had been initiated, the meter was running. Not long after Engressia shared this information with the other phreakers, John Draper discovered that a toy boatswain’s whistle that was included in boxes of Cap’n Crunch cereal in the late 1960s could blow a perfect 2600Hz tone. The unwitting engineer explained that the telephone switching systems worked on a 2600Hz tone, and that Joe must’ve somehow managed to hit that frequency with his whistle. He called AT&T’s tech lab and asked an engineer why he kept getting disconnected. He re-dialed the number, whistled the same song and was cut off at the same point. One day he happened to be whistling a tune while on the phone and was immediately disconnected.

One of the original phreakers was Joe Engressia, a young man who’d been born blind and had developed an ear for perfect pitch. They called themselves “phone phreakers” and they had “meetings” via free telephone conference calls. In no time, he’d figured out a way to make free phone calls through the local switchboard.Īfter he left the Air Force, Draper continued to explore the inner workings of the phone company as a hobby and found some kindred spirits in the process. On a remote base in Maine, there was only one telephone for the soldiers to use, so he began studying Ma Bell’s technology, learning about things like access codes and trunk lines. As a boy, Draper spent most of his time rummaging through the military bases, and scavenging for electronic parts which he added to the radio station he was building in his bedroom.Ī natural-born tinkerer, Draper later joined the Air Force as a radar technician, where his fascination with electronic communication escalated. John Draper’s father was a career Air Force man, and he thrived in the military environment. They do it for the same reason people climb Mt. True hackers don’t break into computer mainframes or other microchipped mazes with the intent of infiltrating the Pentagon or ripping off Big Business.

Not only did the electronics genius use a plastic toy from a cereal box to crack open the entire phone system, he also used his skills to befriend Steve Wozniak and wile his way out of prison “chores.”

John Draper is the hacker’s hero for a reason.
