Who is a phone phreak? A phone phreak is a person, usually blind, because the only things that are in their lives are audio and what they can hear. Phone Phreaking 101 Early phone phreaks in action The Alto system by the Xerox Palo Alto Research Center had a lot of basic stuff, and, in fact, that’s where the Mac graphic user interface came from – the Alto computer that was created at the Xerox Research Center.

Now, when you’re accessing the telephone company at the trunk level, you have got either 3 digits, or 4 digits, 5 digits, 7 digits, 9 digits, 10 digits and so you had to have a way of telling when you were done dialing the number, so you had to have an opening tone, the number, and closing tone. Xerox Alto system became the basis for Mac GUI They would allow you to be able to have an opening tone, the number, and closing tone. This is a program that generates the multi-frequency tones, unlike what the 2600 Hz whistle did, that allowed you to be able to combine 2 out of 6 tones to create and to form a phone number. The Stanford AI lab had a ‘blue box’ program. We’ll talk about some of these pranks later. The cost was $120,000 it had 16 ports on it and it only ran Basic.Ī lot of pranks occurred back in the day too, where people would write programs to do strange things and to confuse the instructor. The exception was Alex Kamradt: he happened to have a BTI in his garage running an HP 2100 mini-computer, and it could only run Basic. Most universities had them large companies would have them. Typical cost for mini-computers was anywhere between $75,000 to $500,000, depending. So, if you were a student, and if you were taking the right kind of courses, and if you had a cool instructor, your instructor would probably give you an account on your college computer back then. Only large universities would have computers back in the day. Hacking is not accessing a computer system illegally it’s recombining different pieces of a program into another program. Hacking started long, long time ago when a program was modified to do one particular function, and what you did was you would then take this program and hack it into different little pieces, recombine them and re-put them together into another program that either can make this program perform better or do something totally, completely different. Hacking is not accessing a computer system illegally and hacking passwords. Let me talk a little bit about hacking: what the definition of hacking is. The virus was nothing more than a little thing, a little display that would come on the screen and say: “I’m the creeper, catch me if you can!” And the purpose of trying to solve the problem was trying to identify where that virus came from, and that was a challenge for hackers. The very first viruses were probably in the early 1970s. There used to be a company called ‘Tymeshare’ whose services were also used back in the day. Ultrix is a form of Unix, and DEC is the PDP-8 and the PDP-11 at the time, and they offered timesharing services. So, the other systems, of course, are Ultrix and DEC. IBM 360 mainframeīack in the day there was the IBM 360, and my exposure to IBM 360 was programming in Fortran using batch cards and I’d have to wait about three hours to find the result of my program run, and more than likely I would find a mistake – forget a semicolon at the end of the statement or something – and had to resubmit the batch again and wait for another three hours. Now I’m going to give you guys a little history of hacking as seen by an old school elder like myself, because when I grew up there were no personal computers. It’s like getting root access to the phone system. This trunk line is not the same kind of line you as a subscriber would use this line is nothing more than an internal trunk line. You would do that by calling an information number or 800 toll-free number, and blow the whistle in, and you hear a little chirp sound, and that indicates to you that you are actually connected to an internal trunk line that is a raw trunk line. Let’s see, if I wanted to dial 234 I would just dial the numbers by repeatedly blowing the whistle that many times, and then that would make a free call. This is a ‘Captain Crunch’ whistle (see image below), and you glue up one of the holes, then you blow the whistle, and that whistle is the pitch that controlled the AT&T telephone switching system. Hello everybody! I don’t know if you’ve heard of me or not, but I was the old school hacker back in the early 1970s, where my claim to fame was using the ‘Captain Crunch’ whistle to make free phone calls. Well-known old school hacker and phone phreak John “Captain Crunch” Draper delineates the major milestones in the evolution of different types of hacking at CONFidence IT security event.
