- * PART I *
- ***************************************
-
- PREFACE:
- --------
-
- In this course, I plan to cover as much
- material as possible relating to tele-
- communications. First, in the syllabus
- are the long-distance services, which
- is the topic of part I. In future
- issues, such subjects as the Bell
- Network, colored boxes, telephone
- electronics, central office equipment,
- computer hacking, and much, much more
- will be covered.
-
-
-
- LONG-DISTANCE SERVICES:
- -----------------------
-
- In an attempt to offer lower prices,
- alternatives to Bell have been set up.
- Services such as Sprint, Metrofone,
- ITT, MCI, Travelnet, and many others
- are all familiar to us.
-
- The basis of all these services are
- that they own their own switching
- equipment. First, we will look at
- those services which use a local
- dial-up. The principle of these are:
- 1) You dial the local #.
- 2) When it picks up you get a 2nd dial
- tone, you then enter a code.
- 3) You then enter the # and whalla,
- you're connected, a free call!
-
- Next, we will look at several of the
- services:
-
-
- SPRINT:
- -------
-
- Sprint, also known as SPC, was one of
- the first LD services.
-
- Many boards contain SPC #'s and I plan
- to include a list of them as an
- appendix to this course so you can find
- your local #.
-
- The codes for SPC are 8 digits long.
- SPC is not considered safe, since many
- people have been busted on it! It is
- common knowledge that Sprint has
- declared war on phone phreaks. So,
- fight back (with care)!
-
- [914 dial-up--> (914) 997-1616
-
-
- METROFONE:
- ----------
-
- Metrofone, owned by Western Union, is
- very popular among phone phreaks due to
- the large abundance of codes and it (at
- the time of this writing) is considered
- fairly safe.
-
- The code is 6 digits long.
-
- To find out the local dial-up for your
- area, just call (800) 325-1403 and ask
- the "nice lady" for the # for your
- area.
-
- FORMAT: At tone--> code+area code
- (NPA)+destination #
-
- NOTE: NPA & A/C are abbreviations for
- area code.
-
-
- ITT:
- ----
-
- ITT is a little different in that upon
- hearing the dial tone after calling the
- local access #, you enter the a/c and
- then the #. You will then hear a short
- tone, you then immediately enter your 7
- digit access code.
-
- [dial-ups:(212)248-0151, (914)997-8576]
-
- FORMAT: At tone, destination # + 7
- digit access code.
-
-
- MCI:
- ----
-
- FORMAT: At tone, 5 digit access
- code + destination #.
-
-
- MCI CREDIT CARD (MCI CC):
- -------------------------
-
- FORMAT: At tone, 7 digit access
- code + destination #.
-
- [212 dial-up: 248-0151
-
-
- NOTE: You can usually call up the
- companies customer service #,
- and say you just moved or
- something and ask for the access
- # for your area code. To find
- out the customer service # call
- dir. asst. at (800) 555-1212.
-
-
- ==============
- =950 Exchange=
- ==============
-
-
- The 950 exchange is a nationwide access
- exchange, in most areas, that includes
- such services as Skyline, Lexitel,
- Allnet and others. All services on this
- exchange are considered dangerous due
- to the fact that they have the traced!
-
-
- SKYLINE:
- --------
-
- SBS Skyline is a new service owned by
- IBM, Comsat and AEtna. It has the same
- local access # across the country:
- 950-1088. It is supposed to have 6
- (possibly 8) digit codes and is alleged
- to be very dangerous.
-
-
- ALLNET:
- -------
-
- Allnet is at 950-1044. It has 6 digit
- codes.
-
-
-
- ===============
- =Calling Cards=
- ===============
-
-
- Calling cards are Bell's version of
- Sprint, MCI, etc. Calling cards are
- used primarily from pay fones. The
- format is:
-
- NPA-NXX-XXXX-CCCC
-
- NPA is usually the a/c of the billed #
- that the call is to be billed to. This
- may be replaced by a 3 digit RAO code
- in some areas.
-
- NXX-XXXX is the number that the call is
- to billed to.
-
- CCCC is a checkcode (or PIN--Personal
- Identification Number) that adds the
- security to Calling Cards. The codes
- used to be predictable until 1983.
- Now CCCC appears to be sequentially
- generated so the codes cannot be
- calculated from a formula!
-
- The easiest way to find these codes are
- in a busy airport or college where
- they are used alot. Just get close and
- copy down someones code (if you are
- that unscrupulous!) Don't rip off poor
- people; go for the rich business pigs!
-
-
- You usually call the operator to make a
- CC Call but on some fortress fones, you
- can dial 0+the number you want to call
- and you will get a recording & tone
- where you enter your calling card #.
- By pressing the # sign (octothorpe)
- after each call instead of hanging up,
- you can make many calls at once without
- having to retype the CC # each time.
- This is good for busy numbers. Also, if
- you want to call the # of the card, ie
- the billed #, you just have to enter
- the last 4 digits of the CC # at the
- tone.
-
- Now, suppose you do get a real
- operator. Since mostly business people
- use calling cards, it is suggested that
- you act a little like a business
- person, ie, rushed, older,
- businesslike, and SLIGHTLY pissed at
- the operator (keyword: SLIGHTLY). All
- you have to tell her is the CC #. If
- she asks for the # you are calling
- from, tell her, but change the last
- digit or 2. If you asks you more
- questions, she is probably suspicious.
- Hang up. Although, you should make up
- some answers to certain questions to
- satisfy the operator that you are
- legit. The most important thing you
- should know when making a CC call is
- the area code and the city of the card.
-
- Finally, in case the operator is
- listening, always talk businesslike for
- the first few seconds until the
- operator clicks off (they have been
- known to listen in on calls
- (understatement)). Also, always use
- CC's from pay fones or Charge-A-Call
- fones only!
-
-
- CAUTION: All the CC codes are now
- rapidly checked due to CCIS
- (Common Channel Inter-office
- Signaling) and ESS
- (Electronic Switching System)
- If you try to hack CC codes
- you can be fairly sure that
- Bell Security (affectionately
- known as the gestapo in the
- phreaking world) will get a
- message from the CO (Central
- Office, ie, exchange)!
-
-
-
- ==============
- =800 Services=
- ==============
-
-
-
- You are probably all familiar with
- WATS. WATS #'s (Wide Area Telephone
- Service, otherwise known as 800 #'s)
- are very popular due to the fact that
- they are toll-free. They often contain
- WATS extneders. Extenders were
- originally used by salesmen in the
- field who called up their company's 800
- # (INWATS #) and then used the
- company's low-priced OUTWATS line to
- make the call. This is cheaper to the
- company than using the Bell calling
- card which has a surcharge.
-
- On the original extenders there were no
- codes! Companies soon realized that
- their #'s were being used and added the
- present day security codes. The
- salesman would then dial the 800 number
- and enter the code (usually 4 digits),
- he would then receive a second dial
- tone from the companies PBX (Private
- Branch eXchange - their own switching
- equipment - ie, switchboard). He would
- then access the OUTWATS line by dialing
- 8 or 9 and then the #. These codes
- were originally hand-hacked, but
- some pioneer phreak added an interface
- to Charlie, his Apple II computer,
- which was capable of generating DTMF
- tones (Dual-Tone-Multi-Frequency - ie,
- generic term for Touch-Tone (TM)) and
- trying all the codes. The only
- problem was that Ma Bell got suspicious
- when they saw that someone called the
- Joe Blow Rubber Company 800 # in
- California 4,568 times at 2 AM and each
- call lasted for only 1 second!
-
-
-
- TRAVELNET:
- ----------
-
- Travelnet is a service that uses WATS
- as well as local access #'s.
-
- The 800 # is (800) 521-8400.
-
- After the tone, enter the 8 digit code,
- if the code was right you'll get a
- second tone, then enter the area code
- and number.
-
- Travelnet is also unique in that it
- accepts voice recognition for those
- times when a touch-tone is not
- available (How convenient!). If you
- don't do anything after the tone, you
- will hear a voice that says,
- 'authorization #, please.' You then
- say each digit SLOWLY. It will beep
- after you say each digit. After each
- group of digits, it will repeat what
- you have said. Say yes if it is right,
- otherwise, say no. If the
- authorization code is correct, it will
- say thank you and it'll then ask for
- the destination #. Follow the same
- procedure as above. The voice system
- is very user friendly and you should
- have no problems with it.
-
-
- TEL-TEC:
- --------
-
- TEL-TEC is at (800) 323-3026. In my
- experiences, you usually get a very
- shitty connection. This I use for last
- resorts.
-
- FORMAT: 6 digit code + dest. #
-
-
- CAUTION: Like the 950 exchange, 800
- numbers can be easily traced.
- This doesn't mean that they
- trace everything, though.
-
-
- Others:
- -------
-
- There are many other 800 services and
- PBX's (such as the Dimension 2000 at
- 800-848-9000). There is just not
- enough room to discuss them all. As
- you have probably noticed, I have
- posted no codes. Check the phreak
- section of various BBS's to find the
- latest codes or hack them yourself.
- Hand-hack good possibilities or use a
- "smart" modem with a hacking program
- (contact your local pirate).
-
-
-
- HOW MA BELL CATCHES PHONE HACKERS:
- ----------------------------------
-
- Besides suspicion and random checks, Ma
- Bell sets up "trap numbers". Trap
- numbers were set up on certain dial-ups
- such as Sprint, MCI, etc. Whenever,
- the dial-up is called a "trouble card"
- is dropped at the central office. This
- means that a record of the called #,
- the CALLERS #, and time are printed
- out. These cards (or printouts in an
- ESS CO) are usually ignored unless SPC
- or somebody detects fraud, ie,
- unauthorized use of a customers acct.,
- then they call Bell and find out the
- name and number and instantly nail the
- phreak who made the call. They will
- then either demand that you pay some
- enormous fee and they'll forget the
- whole matter; give them info on other
- phreaks, boards, etc.; or prosecute you
- on the federal rap of Theft of
- Communications service, which carries
- fines of upto 10 years in jail and/or
- $10,000. They usually don't go for
- legal action first, though.
-
- Why does Bell help their competion?
- Actually, it is rather simple. People
- were using Sprint to break into Bell's
- ESS computers. Bell could only trace
- the call back to Sprint. So, Sprint
- helps Bell catch the people it wants
- and visa-versa. ("You rub my back and
- I'll rub yours" type of deal.)
-
- By the way, trap numbers are also how
- Bell catches people who make harrasing
- phone calls to private residences.
-
- Finally, do not forget that these
- services have a copy of the number that
- you called. So, if a customer says he
- didn't call a certain #, they will
- usually call up that # and try to find
- out who did call at that time.
-
- So, to be safer on SPC, MCI, and
- others, follow the following
- suggestions:
-
- 1) Use a fortress fone (pay fone)
- whenever possible. Although, they have
- been know to stake out pay fones. Just
- don't use the same fone over and over
- again. In other words, move around.
-
- 2) Only call institutional
- switchboards, business that have no
- record of your call, and friends who
- are instant amnesiacs.
-
- 3) Try to keep all calls under 15
- minutes when possible.
-
- NOTE: No system is totally safe! When
- I classify something as safe or
- dangerous, that is just with respect to
- my opinion as well as that of several
- other phreaks. These opinions are based
- on how many people have been busted on
- them, what type of equipment they are
- using, and inside information. I
- cannot possibly guarantee that you will
- or will not get caught. Actually, with
- CCIS and ESS nothing is really safe
- anymore. Besides, what phun would
- there be in life without risks!
-
- Coming soon:
- ------------
-
- In Part II, we will look at the special
- Bell numbers such as CN/A, ATT
- Newslines, loops, ANI, ringback, and
- 99XX scanning.
-
-
-
- Until next time, I would like to leave
- you with a quote from The Magician:
-
- "Many people think of phone phreaks as
- slime, out to rip off Bell for all she
- is worth. Nothing could be further
- from the truth! Granted, there are
- some who get their kicks just by making
- free calls, however they are not true
- phone phreaks. Real phone phreaks are
- "telecommunications hobbyists" who
- experiment, play with and learn from
- the phone system. Occasionally this
- experimenting, and a need to
- communicate with other phreaks (without
- going broke), leads to free calls. The
- free calls are but a small subset of a
- TRUE phone phreaks activities."
