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.

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 Telecommunications department. The PTT remains in charge of the network however, and they can continue charging ridiculous amounts for it. The state monopoly is enabling the phone company to suck money from our pockets. HACKER POLICY ------------- Redirect phone lines to other numbers (they don't even know it exists, we do it all the time, to receive free collect calls). This trick courtesy of The KEY. Route calls through other countries to make things cheaper. (Spain was our favourite before they closed it off). Generally screw 'em......
