- Hacking In Holand & The Numbering Plan
- --------------------------------------
- By: Rop and The Key
-
-
- In Holland, hacking started out late. The first real hacks were
- done in the early eighties. Among these hacks was the 'RIVM hack',
- hacking the computer of the dutch health-inspection (FDA). Because
- even patient names were listed here this got a lot of publicity.
-
- Around 1984/1985 the movement grew rapidly because of the movie
- 'Wargames' and publications in the "Volkskrant", the country's major
- left-wing newspaper. It was around these days two students hacked the
- '008 computer', the directory-assistance system, owned by our local
- Ma-Bell clone, the PTT. Because hackers had access to a lot of
- unlisted phone numbers this was front-page news in all of Europe.
-
- Shortly after this hack, Jan Jacobs published the book 'kraken en
- computers' (hacking and computers), about the uprise of the hacker
- movement in The Netherlands. Jan Jacobs is also a free-lance reporter
- for the 'Volkskrant' which explains their scoops on major hacking
- events. In those days, he himself was a hacker.
-
- Things remained relatively quiet, although the CCC kept scaring
- everybody with their marvelous hacks all over the world over the
- packet-network. X-25 hacking in Holland is relatively new, not because
- the net was not there, but because it was still to easy to use the
- telephone. Only recently dutch hackers discover that the X-25 net
- offers them the opportunity to make low-cost global hacks.
-
- Another group had sprung into life in the early eighties, phreaks.
- These phreaks concentrated on mobile phones however, because our ATF1
- (car-phone 1) system is as leak as a basket. Using a CBM-64 or other
- simple hardware and an FM-tranceiver, every weirdo could make free
- calls all over the world. This lasted until there were so many illegal
- car-phones that the costs began affecting the total PTT turnover.
-
- The PTT then made it impossible for car-phone users to make
- international phone calls automatically and told their international
- operators to check for fraud carefully. By that time all the phreaks
- were rich from selling their technique 'to friends only', and bored
- stiff, because the PTT had taken their toy away. There was a new
- system, ATF2 (compatible to the scandinavian NMT system), but this was
- to complicated (in those days) to hack (considdering these people were
- not computer minds but mainly high-frequency experts).
-
- The phreaks met the hackers and they decided their goels were the
- same.
-
- The PTT phreaked out when the world found out that some of the leading
- hackers had switched to phreaking. When Personal Computer Magazine
- published an article about phreaks making free calls all over the
- world through an old exchange in Denmark (which could be reached free
- of charge), all hell broke loose. The magazine contained our list of
- frequencies for the CCITT-4 system, so suddenly everybody was a
- phonephreak. The free lines to Denmark were rerouted, some other gaps
- were closed, but no action could be taken against the phone phreaks
- (The Key and me among others), because no phone-fraud legislation
- exists in Holland. Can you imagine what it's like to live in a country
- that has NO phone-fraud laws?
-
- Since then things have cooled down (there are only about 40 real
- active hackers in the entire country, so things tend to get quiet
- every once in a while), but as soon as anything happens, we'll let you
- know.

-
- NUMBERING PLAN
-
- The dutch phone system has a numbering plan that is far more
- complicated than the american phone system. Telephone numbers can be
- divided in several classes:
-
- 0XX-YYYYYY[Y] Larger cities. XX is random (very large cities
- have a 0 as their last digit).
-
- 0XXYY-ZZZZ[Z] Smaller towns. XX is the number of the district
- (note: these numbers cannot be handed out to
- bigger cities). Holland has some 20 districts,
- amsterdam is 29. (the Amsterdam city code is 020)
-
- 00X
- 001X Special numbers, see below.
-
- 06-0XXX Free numbers
- 06-0XXXXXX Free numbers
- 06-022XXXX International Free Numbers, connect to foreign
- companies etc. (we even have a number for
- making AT&T calling card calls for free,
- 06-0229111). When all european borders
- disappear in 1992, this group is expected to
- grow rapidly!
- 06-3XXXXXXXX Special high cost numbers, mainly phone-sex (the
- owner gets 2.5 $ct./min, the PTT gets 22.5. This
- makes the PTT the country's biggest pimp)
- 06-4XXX Free numbers, explosive. (This means a lot of
- traffic at one time, TV-shows and the like)
- 06-4XXXXXX Free numbers, explosive.
- 06-51XXXXX Beepers (sorry, paging equipment)
- 06-52XXXXXX ATF2 (mobile phone system, NMT compatible)
- 06-524XXXXX ATF1, West and Middle Netherlands
- 06-525XXXXX ATF1, North Netherlands
- 06-526XXXXX ATF1, South Netherlands
- 06-8XXXXXXXX Split costs, the caller pays a portion of the
- costs, the called party pays as well (80%+80%=100%
- according to phone company arithmatic)
- 06-9XXXXXXXX Special high cost numbers, no phone-sex
-
- 09-....... International access. For the States i.e., we dial
- 09-1XXXYYYZZZZ. Our country code is 31.
-
-
- SPECIAL NUMBERS
- ---------------
-
- 002 Speaking clock
- 003 Weather
- 004 PTT-customer service (contradictio in terminis)
- 005 was the mobilophone network (pre-carphone mobile
- operator service), now tape telling callers that this
- service no longer exists.
- 006X Used by PTT for mechanics to call in. 0069 always
- plays a tape listing the home-phone number of the
- mechanic on duty for that region.
- 007 PTT-repairs (uses pigeons for further internal
- communication, judged by their working speed)
- 008 Directory assistance
- 009 Was message service, for telex and other services,
- their new number is 06-0409. tape.
- 0010 Was national operator, now 06-0410. tape.
- 0011 Once planned as a countrywide emergency number. Once
- they got to installing it they had the 06 exchange,
- which was newer and better, so the discussion started
- again...... tape now
- 0012 Telex number info
- 0013 Telex repairs
- 0014
- 0015
- 0016 Was international operator, now 06-0410. tape.
- 0017 Post office customer service
- 0018 Was international inquiries, now 06-0418. tape
- 0019 Dead
-
-
- TARIFFS
- -------
-
- A toll-impulse costs 7.5 $ct, impulses are 50 Hz/48V pulses on both
- lines (tip and ring, called A and B here), so can only be detected
- relative to the ground potential. On modern exchanges you have to pay
- for these pulses, as well as for the DTMF-facility (sound familiar?).
-
- Calls cost more in the day time (0800/1800 hrs), than on weekdays.
-
- Within your low-tariff zone (about 30 miles around your home), it's
- one tick every 5 minutes, or once every 10 minutes at night, outside
- of that zone one tick every 1.5 minutes, 45 seconds at night.
-
- International calls from Holland are terribly expensive, USA costs
- $2.00 a minute, but there's a lot of countries that cost over $3.50 a
- minute.
-
-
- SPECIAL THINGS (everybody has some)
- --------------
-
- 030-555555 for conference calls (operator only, she calls you back,
- so phreaks are out of the question). The do-it-yourself
- conference has not been invented here (yet).
- 06-0101 All sorts of special services, addresses from the phone
- book (costs $1.25 to get an address!) etc. Also national
- collect calls ($2.50 bonus for PTT, $1/min)
-
- *XXX*.....# Some exchanges have this feature. It means you redirect
- all calls for your phone to the given number (dots). PTT
- offers this service for a lot of money as *21*....#, but
- this is different. With the *XXX*...# feature the phone
- doesn't ring on the redirected phone (with the *21
- feature it does three times before forwarding the call).
- The *XXX*....# feature is a non documented feature, even
- at the PTT not many people have heard of it. Alas, not
- many exchanges feature it. The XXX can easily be found
- because if you're one digit off the system reacts with a
- nonexistent-tone (three tones, each one higher than the
- preceeding one), so there's only 30 possibilities.
-
- Things like call-waiting, or even specified bills do not exist here
- (yet). When they come, they'll be expensive, that's for sure.
-
- PTT POLICY
- ----------
-
- The company has a monopoly on all telecom facilities that expires next
- year (1989). Up till now we could not even buy our telephone sets
- somewhere else (legally). People finally realised this was ridiculous
- and decided to privatise the PTT g people, Ms. Wilder usually
- manages to make do with the paycheck she receives, while always
- thinking about ways to get more money.
-
- But Ms. Wilder had an all-to-common problem: she got over her head in
- debt, and began having trouble meeting obligations to her creditors.
- Gradually she was catching up, but one of her creditors got impatient
- and decided to place her with a collection agency.
-
- L & P Financial Adjusters, 6326 North Cicero Avenue in Chicago was the
- agency given the assignment of collecc cc cc c
