Phreaking



Phreaking is a slang term coined to describe the activity of a subculture of people who study, experiment with, or exploit telephones, the telephone company, and systems connected to or composing the Public Switched Telephone Network (PSTN) for the purposes of hobby or utility. The term "phreak" is commonly thought to be a portmanteau of the words phone and freak, though a more plausible explanation of the term may be that some phreakers make use of various audio FREQuencies to manipulate a phone system. "Phreak", "phreaker", or "phone phreak" are names used by and towards people who participate in phreaking. It is often considered similar, and therefore grouped in category with computer hacking. This is sometimes called the H/P culture (H for Hacking and P for Phreaking.) ==History of phreaking== The precise origin of phone phreaking is disputed. One could argue that the inception of the telephone by Antonio Meucci and Alexander Graham Bell could be the origin of phreak-like experimentation, or other unnoted telecommunications enthusiasts. Modern day phreaking, however, is more likely to be traced to the United States in the late 1960s and early 1970s when AT&T started upgrading Telephone_exchange to the more complex crossbar systems. It was during this time in the early 1970s that famous American phreak John Draper, alias Captain Crunch, learned from his blind friend Joybubbles (née Joe Engressia) of a technique that manipulated AT&T's long distance signalling system by sending a 2600 Hertz tone down a telephone line. This led Draper to the invention of a device with the intention of specifically manipulating the telephone system without the permission of the telephone company. This device became known as the blue box. Draper was featured in an article by Ron Rosenbaum titled ''Secrets of the Little Blue Box'' in the October 1971 issue of ''Esquire Magazine'' for his exploit. The article attracted interest of other soon to be phreaks Steve Wozniak and Steve Jobs of not yet formed Apple Computer. [http://www.woz.org/letters/general/03.html] Other phreaks popped up around this time such as also American Evan Doorbell and Mark Bernay who conducted their own independent exploration and experimentation of the telephone network separate from Captain Crunch. Evan Doorbell formed with Mark Bernay a group of phreaks known as Group Bell. He is semi-famous character in phone phreaking today for his internet publication of telephone exploration conducted by himself in the 60s at his website ''Phone Trips.'' [http://www.wideweb.com/phonetrips] As the 1970s moved into the 1980s, the revolution of the personal computer created in an influx in tech savvy users, and also the popularity of computer bulletin board systems (BBS) that computer users dialed into with a modem. These BBS's became popular for computer hackers, and others who liked to tinker with technology. They also became popular for previously scattered independent phone phreaks to share their discoveries and experiments. This not only lead to a collaboration between phone phreaks like never seen before, but spread the notion of phreaking to others who took it upon themselves to study, experiment with, or exploit the telephone system. This was also at a time when the telephone company was a popular subject of discussion in the US when monopoly AT&T was forced into divestiture. Computer hackers started to use phreaking skills to find telephone numbers modems belonging to businesses, which they could exploit. Groups were formed around the BBS hacker/phreaking (H/P) community such as the famous Masters of Deception (Phiber Optik) and Legion of Doom (hacking) (Erik Bloodaxe) groups. In 1985 an underground e-zine called Phrack (a combination of the words Phreak and Hack) started circulation among BBS's, that focused on hacking, phreaking, and other related technology subjects. In the early 1990s H/P groups like Masters of Deception and Legion of Doom were shut down by the US Secret Service's Operation Sundevil Phreaking as a subculture saw a brief dispersion in fear of criminal prosecution in the 1990s, before the popularity of the internet created a re-emergence of phreaking as a subculture in the US, and also spread phreaking globally. ===2600 Hz=== ''See also 2600 hertz'' 2600 Hz, the key to early phreaking, was a signal sent to the long-distance switch to indicate that the user had hung up the phone. At that point the call was not completely disconnected. Although the long-distance hardware thought the call was disconnected, the local user was still physically connected to their local crossbar — it knew that the user was still connected because the voltage never dropped. This left the system in an inconsistent state. The dialer was still connected to a long-distance trunk line and switch at the remote switching center that was perfectly willing to complete or further route calls. A number of people in the 1960s discovered a loophole that resulted from this combination of features. The trick was to call a toll free number or long-distance directory number and then play the 2600 Hz tone into the line before the call was answered on the other side of the line. Then they simply dialed the number they actually wanted on a blue box, and the remote crossbar happily connected them for free. Of course when they were connected to the diverted call their local central office would be alert and the technicians began searching for inordinately long directory calls or excessive dialing to particular toll free numbers. Many phone phreaks were forced to use pay telephones as the telephone company technicians regularly tracked long-distance toll free calls in an elaborate cat-and-mouse game. As the knowledge spread, the growing number of phone phreaks became a minor culture onto their own. They were able to train their ears to determine how the long lines routed their calls. Sympathetic (or easily Social engineering (computer security)) telephone company employees gave them the various routing codes to use international satellites and various trunk lines like expert operators. The phone companies quickly caught on to the scheme and slowly deployed a number of systems to defeat it, but the phreaks felt that a true solution would be impossible because it would require adding hardware (a filter) to every line on every crossbar in the world. Unless the phone company replaced all their hardware, phreaking would be impossible to stop. AT&T instead turned to "the law" for help, and a number of the more famous phreaks were caught by the FBI. Eventually, the phone companies in North America did, in fact, replace all their hardware. They didn't do it to stop the phreaks, but simply as a matter of course as they moved to fully digital switching systems. Unlike the crossbar, where the switching signals were carried on the same lines, the new systems used separate lines for signalling that the phreaks couldn't get to. This system is known as Common Channel Interoffice Signaling. ==One box, two box, red box, blue box== Many phreaking techniques can be implemented with small electronic circuits, easily made by hobbyists once the secret of their operation is known. The first circuit to generate the switching tones needed to reroute long-distance calls was nicknamed the blue box by an early phreak who had built one in a blue enclosure. Soon, other types of phreaking circuits were given similar names. At one point, pay telephones used specific tones (separate from the MF tones used for numbers) to signal the deposit of a coin. These tones, then used only for long distance and overseas calling, would signal the amount deposited to a tolling computer called ACTS(Telephone). Phreaks learned the frequencies used and produced circuits to spoof them. Such a device became known as a red box. It was also possible to call one pay phone from another and then simply record the sounds as coins were deposited in the first pay telephone. The phreaked call was then completed and when the operator asked for payment the phreak would play back the recording of the sounds (including the physical sound of the coins being deposited into the coin box) into mouthpiece of the telephone for the benefit of the operator. To combat this, telephone companies used myriad devices local to the payphone, including a muted handset. Red-boxing (the act of using red boxes) ceased to work in most areas in the 1980s when the phone companies installed a sensor that actually detected the coin falling into the box. Finally they moved this signaling out-of-band completely. However, in some areas where telephone equipment was not upgraded until later, it remained effective into the 1990s. Even in the late 1990s (and perhaps later), it was still possible to defeat the local coin-drop switch on many analog phones by simply dialing the desired number with the long-distance prefix, since (apparently?) the state of the local coin-drop switch could only be detected for local calls because (again, apparently?) the call was routed out to long-distance equipment and back. Muted handsets could sometimes be defeated by dialing with operator assistance. Dozens of other types of "boxes" were invented. In the Bulletin_board_system scene of the late 1980s and early 1990s, crude ASCII art diagrams of phreaking box schematics circulated on bulletin board systems. Many of these designs simply cloned particular telephone features not usually accessible on residential phones, such as a hold button or the letter keys used in Autovon (the silver box). Many were useless, some were faulty, and some were pure hoaxes: for instance, a "blotto box" which supposedly could take out an area code with a huge electrical charge. Phone phreak Evan Doorbell took an unusual approach to "blueboxing." Instead of specialized devices to tap into the phone network, he used an ARP Odyssey keyboard synthesizer, which because of its capability of playing two notes at once (unlike virtually all other synthesizers of the period) was capable of producing not only 2600 Hz tones, but MF tones as well. ==Modern day phreaking== In the late 1990s phreaking and computer hacking saw enormous growth as a hobby and subculture after the popularity of the Internet. New bulletin board systems were created, and texts from BBSs of the 1980s saw redistribution globally. ''2600 Magazine'', an indepently distributed magazine for phone phreaks and hackers became popular and helped create an atmosphere of technology liberation, as well as informing hackers and phreaks of reader created 2600 Meetings as well as hacker conventions like DEF CON and H.O.P.E.. Modern-day phreaking is socially comprised of independently created zines, BBS's, and recently a trend in internet streaming_media H/P radio_programming's like ''Radio FreeK America'' [http://www.oldskoolphreak.com] and ''Binary Revolution'' [http://www.binrev.com]. These radio shows often work together, hosting each other's data, or sharing hosts. This is not new, however. Since 1988 a radio show called ''Off the Hook'' with a hacking and phreaking format has been in production by Eric Corley (editor of ''2600 Magazine'') on WBAI 99.5 MHz in New York City. ''Off the Hook'' has been streaming their radio show since the late 1990s. Phreaks have taken a new interest in the recent creation of domestic VoIP providers like Vonage and open source PBX's like Asterisk that interface with VoIP protocols.

This page has recently been butchered by people who do not know whereof they speak. Eventually I will attempt to fix it. User:Mbstone 17:47, 23 Nov 2003 (UTC) :Could you please be a bit more specific if this still applies at all? User:Falcon Kirtaran 02:53, Mar 22, 2004 (UTC) ---- I just read in this article about how you can dial a number by rapidly taping the 'hang-up hook'. So I picked a simple phone number (411), and tried. Freaking cool, it worked! You never know what you'll learn from reading Wikipedia! User:Ike9898 02:21, 23 Jan 2004 (UTC) ---- Possibly apocrypha, but I always remember hearing that blind kids made up a large part of the "cutting edge" of phreaking. Anyone ever remember hearing similar? (First spotted it in the Esquire article linked to from the 'blue box' article, a few years ago...Then heard rumors.) On one hand, it makes some sense; Schools for the blind were (and are) notoriously constricting places, and prior to mainstreaming, the vast majority of blind kids were sent to them. As one may expect, when you essentially put a bunch of preteen kids into a cage, they begin getting creative. On the other hand...it almost sounds too good (for me) to be true... -User:Penta 00:44, 22 Mar 2004 (UTC) :It is essentially true but the field was not exclusive to them. A lot of them were bad at it, like a lot of seeing people were good at it. Now, it is not a question of being good or bad but diligent. User:Falcon Kirtaran 02:52, Mar 22, 2004 (UTC) ---- It's almost completely true actually. A gentleman by the name of Mark Bernay (an alias actually) taught the blind kids mentioned in that Esquire article about phreaking. Mark had learned from someone he bumped into on a loop randomly. He never met this person, but what he told him worked. These blind kids proceeded to teach the well known Cap'n Crunch all about what they had learned, and the rest is history. User:Sam Etler 07:10, Jun 16, 2004 (UTC) ---- I question the edit made by 202.7.x.x. If anyone agrees, please revert. User:Falcon Kirtaran 16:29, 16 Jul 2004 (UTC) :I don't see the point in removing the stuff about TAP. That's factually accurate as far as I know. User:Sam Etler 05:41, Jul 19, 2004 (UTC) ::Anything else, or can the edit be reverted? User:Falcon Kirtaran 17:47, 19 Jul 2004 (UTC) :::After reading closely, I'd say revert. That seems to be a generally accepted aspect of phreaking history. 202.7.x.x can always add to this discussion if she/he thinks we're wrong. User:Sam Etler 02:00, Jul 20, 2004 (UTC) == Joe Engressia is the FIRST Phreaking == Where is he? He was the first!!! [http://images.google.com/images?&q=captain+crunch+1582 I] agree - he has been mentioned of course as the [http://home.c2i.net/nirgendwo/cdne/ch4web.htm blind whistler with perfect pitch] which reports Draper then first used the whistle and [http://www.woz.org/letters/general/03.html Woz says the same thing] basically, along with [http://www.rotten.com/library/bio/hackers/captain-crunch/ rotten.com bio library] on Draper. A link to [http://www.telephonetribute.com/phonephreaking.html the History of Phone Phreaking] is a required!!! along with Captain Crunch's page already listed. =) thanks ==Huge Update== I greatly updated this article, and feel I helped it out tremendously. I re-named the Origins of Phreaking to History of Phreaking, because I felt it was more informative. Sorry to whoever wrote the Origins, Crossbar, and Modern Day Phreaking sections but I basically gutted and re-wrote those sections completely because they were vague, uninformative, and in some cases just plain wrong. No offense. I included a link to the crossbar article in it's involvement for this article, but a lengthy description of crossbar is really not neccessary. I added a lot about the interrelation between computer hacking and phreaking, and also refined the definition quite a bit. If you notice any grammatical errors, feel free to fix. I'd like to see future development of this page, including examples of the spread of phreaking from the US to other countries (UK, Australia?). I feel brevity is optimal compared to choppiness at this point. I don't know how to do that though, so if somebody could do that for me, it'd be appreciated. Also can somebody fix the section "Non-English Wikipedia entries on phreaking." The links aren't displaying properly. I'd love to hear your comments and thoughts on the revision, and any ideas for the future of this article. --User:BriskWiki 10:57, 11 Apr 2005 (UTC) :BriskAttivo is love. Thanks Brisk, the article rules now. ::And I thought this name would be semi-anonymous. :-) ::--User:BriskWiki 13:34, 11 Apr 2005 (UTC) == "nee" (English word) to "née" (French feminine form) == To Radman1: Please look up "nee" and "née" here in the Wikipedia before you change things again. "Nee" (which I used) is an English word referring to a former (or birth) name. You changed it to "née" which is French, not English, and is the feminine form anyway. Engressia is male. When I reverted your edit, you should have checked your facts before changing it again. I see that Fubar Obfusco has just removed the word entirely rather than watch us have an edit war, but it clearly belongs there, as Joybubbles isn't an alias. It's his actual new name. Please respond here or just put "nee" (English word) back in. I'll wait a few days to hear from you. : Interesting. The edit was meant to bypass the redirect, not a revert war -- it's now linked as née, hope this works well for everyone. —user:Radman1 (User_talk:Radman1) 14:31, 2 Jun 2005 (UTC) :: Néeither word is néeded héere. Using the Fréench is an afféectation, and an incorréect one if you use the féeminine. (''Né'' would be ''correct'', but snooty.) Making up a word "nee" and claiming it to be an Éenglish géender-néeutral word is just silly. :: Moreover, the implication of using ''né'' (or any derivative form) is that the name thus marked is a birth name as opposed to a later legal name. (The traditional form refers to a woman's maiden name as opposed to her married name.) Internet handles and ''noms de crime'' need not apply. :: Besides, the sentence reads better without it. --User:Fubar Obfusco 14:46, 2 Jun 2005 (UTC) ::: Agreed. Néever again! —user:Radman1 (User_talk:Radman1) 14:49, 2 Jun 2005 (UTC) :::: Fubar Obfusco explained exactly why it should say "nee," but since he didn't read Engressia's article, he thought he was explaining why we don't need it. We need the "nee" here because this individual was born as "Joe Engressia" and legally changed his name to "Joybubbles." It's not a "handle" or "nom de crime"--it's a legal name and we're showing that "Joe Engressia" was his birth name, which is precisely what "nee" is for. User:Gary D Robson 17:35, 2 Jun 2005 (UTC)
