A current and compulsary analysis of phreaking
Phreaking is my newest passion. Beige boxing, red boxing all of it is great; if you do it right. Today the risk for phreakers is greater than ever. This TF is focused mainly on
the in’s and out’s of hardware and OL or over line phreaking. Many people have said that phreaking is dead I assure you this claim is not true. Thousands of people tap their
neighbor’s lines, scan their individual prefixes, and highjack local PBX’s.

(1.) The Telephone: Our Weapon of Choice ????
“Concentrate all your thoughts upon the work
at hand. The sun’s rays do not burn until
brought to a focus”
~Alexander Graham Bell
The telephone(fone has changed over the years details on this are found in “A History”. The telephone needed for modern phreaking is your regular old touch tone fone.
Touch tone fones connect to a regular old home fone jack, chances are you already have a couple.
When you pick the fone up of the hook, a circuit is broken or “opened”. Talking in to the mic on your handset fluctuates the signal between you and the phone
company(BELL), causing sounds in the speaker. Pressing buttons on the keypad produces special sounds or “tones”. These tones can be recognized by BELL’s computer
and they are what direct your call the the target line. Tones are very important, you should have a copy of as many as you can get your hands on. The best wayto do this is
to either find a website were you can download them or use a tape or digital recorder and record as many tones as you can from your fone. These tones will come in handy.

(2.) DMTF(Dual Tone Multi-Frequency)??????????????
Ok first things first DTMF stands for Dual Tone Multi-Frequency. Its the noises your phone makes when you dial a number or press; star or pound. Pick up your phone and
press some keys thats an example of DTMF. Back in the old days the teclo realized that the pulse dialing system was inefective and needed to be upgraded, the answer
was DMTF.
First you need to know that when you press a number on your phone it produces two tones simultaneously. This table should be of some help:
╔══════λ#9552;═╗
║ 1 2 3 a = 697Hz║
║ 4 5 6 b = 770Hz║
║ 7 8 9 c = 852Hz║
║ * 0 # d = 941Hz║
║1209Hz 1336Hz 1477Hz 1633Hz ║═════λ
The A,B,C, and D on this chart are advanced buttons used by teclo operators to perform special operations from their terminal.(very fun to play with) The beauty of DMTF is that it is so simple that all of us can understand it and use it to our advantage.

(3.) The Most Basic Phreak
??????????????????????????
The most basic phreak you can perform is manual wardialing. Pick up your phone and dial an interesting number. What is an interesting number you ask? Well an interesting number is just a unique number. For example 999-0000, 444-3333, 8686868, be imaginitive and explore the wonders of your area code. You should write down all of your results. Every number you call should be noted to make sure you do not waste you time calling the same number over and over again. Most likely you will find some residential numbers if you do just say: “oops i dialed the wrong number, good bye”. If you are lucky you will dial a number and get either an over the line service, a business’s PBX, a test line, a loop line, or a modem. All of theses things will be explained in the articles to come.
