HACKING ON TELENET It's as easy as 123456! Telonet. Or. to.!>e mo..c ,,,,,cillc. GTE Telenol. A rna"i"" network formed by the -p.ople and technology that were' used lo develOp packet .wilc1i.ing for the Department of Defense. Telen~t .'.I'M puri:haoed by OTE in 1979 and has bee~ growing in ai>:e and revenue ever since. .. There are quite a rew data network< in existence today. Datapac, Autonel, Tymnct,_ Arpan.l~ .to name some of the belter I:nown. A dat.l network is basically a c"lIection of mainframe., specialized mini'. and high.,peed line,. Through Telenel, yo~ can connect 10 literally thousand' or computors, all oYerthe country, even lhe wnrld if ynn know 'm: proper procedures. AU thi' ispo..ihJc: by malOng a local phnne call, in most part. of the country. [Telenet = .. number:< are made readily avaWlhle to the public by Telenet and 'Y"em. on tbe nelwork, .uch a. Ihe Source, Cnmpu.erve, etc.] Once your mndem i. connected '0 Telenet, you have ,n hit (wn carriage re'urn•. vou'n ..., TELENET XXX XXX where 'he firs' 3 X'. are the area code you're connected '0 and 'he rest compri.e the Tcleno' node identifier, Vou'II,heo be asked fol;, your lerminal iden'lfier.

A' thi. poinl ynu firs' rcceive 'he@ prompt.·1t is frotU here lhat ynu get plaeo., And that'. what'••o unique about Te Telenet address. Then you en,er the area code of Ihe compu,er you wanl to connect'lo, followed by a tWO or three digi, code.· Thal'.an Ih.,.e is 10 it T..lene' tell. you whether or nOl you've found a working compuler. If you wanl to. exit from ooe Compuler and connect 10 anolhcr; ju.1 lypec an ~@w. You'll then gellbe Tclentt @ prompl, Before you type the tleJlt ·addres., lype ~Dw to .di'connecl from lhe computer you're still connected '0.

The-area code i. 617. Have your computer "an its search at add .." 61700:1. If you gel connected 10 a compu'er, Telenet will ,tip a line and prin' 617 001 CONNECTED. If you don',.' ge, connec'ed, Il\erc .a.. a varie,y of mes""ge, you could gel. 617lJOi REJECTING, 617 001 NOT RESPONDING, 617 001 NOT REACH. ABLE, 617 001 REFUSED COLLECT CONNECTION "re a few Oflhcm. They all mean basically lbe same thing_

there i. no way ,0 hook up to this nodre... A'ihis poin" ,everal thing' ~n bedooe. Nalurally, you'll wanl lo inerc,nent Ihe address by one nod ,,,,,rch ror a computet al address 611002. But how do you have your computer recognize when a connectioa has been made? This i. ~eoe ..ary becau.. you can't just keep entering C'XXXXXX nver and over-once you get connecled, you have to enter Ihe ~@" In get baolr-lO the Tele~el promp" followed by a ~D~. Ofcou...., you could type C XXXXXX, folio'oVCd by ,'@w,followed by "OW ror ever)' a~lempl, bu, that can gel ralher lime eon.orniog. It's belter SImply to be able 10 sa""' lo.di,k or OUtpul to a prin,er the addresses of con~eel;ons. And, fortunately for haokcrs, Telene' makes that very ca,y. Vou o;:an eilher search for a 'Iring that ha' lhe word "CONNECT" in il somewhere-lhe only lime you'd find one would be when you gOI 'he CONNECTED me.sage. But, as we mentioned earlier, an exIra line i' ,kipped righl before ,he CONNECTED message, for some reaSOn. Why 'no' .imply look for ,hal extra line? If you gel iI, record 'he address, ,end 'he "@~ aod "D" aod incremenl by 1. lr you don'l get ,he extra line, simpiy inc",ment by I. Naturally, you. will be collecling Teleoel addre"e, fo'r informatiooal putposes only, to find out which compule .. are located where, in case you ever have 10gel on'o one ,n an emergency of ,ome sorl.. Keep ia mind 'hal you are nol emering any of Ihe.. compu'ers; you're merely oonnecling ror a brier .econd Or lwo. And ,here is nO login procedu", 0< identity check for Telcnel, so you'", nOl fraudulently using lheir system ei.her. AI,o, the area code .y.tem is not lhe only 'ystem .'hal work. 00 Telenel. These are ,imply,el up to be conven,enl, but an address <;an aelually have any kiod of a numher io it.

SOME THOUGHTS ON "GARBAGE PICKING" a phone conversation lhal you're having. If you build an amplifier lhal can filler out Ihe background noise and amplify only the narrow bandwidth whore the voice is 'fan,milled lhrough lhe phone lines, you might be able [0 make oul whal the [olks are .aying. for aillhe good it will do yoil. BUllher. are olher things you can he.f in thi, electronic garbage heap. Suppo,e one day you hear .ross-talk of. modem conversation? If you could amplify it and reed it imo your compuler, you would be able [0 mnnilOr ,omeone el,e's enlire compule, ,,,,,ion, Suppo,e you heor someone entering in lou.h-ton.'" code. to some local call extender? All you have to do is build yourself a lone decodor (you <:an find schemali<:$ for lhe,e 'hings in any Radio Shad) and figure ou' what the person entered. Obviou,ly, once you are able 10 amplify the ero,,_tall:. 10a rea,onablolovel, your best bet i' to tape-record the material so that y~u can experimenl with the besl way to feed il into the computer or tone decoder Ihat will be further deciphering it, There have been talc, told of one cnterpri,ing phre.k who buill a tone decoder and then called up his favorite cail ealender. He then called some "dead" Hne(such as thuI1ent half of a loop line ,omewhere; other possibiliti.. could be a disconnected number [you hear 'ilence after the recording fIni,hes] at even your own phone, if you have a ,econd line you can use) and luroed on his lape recorder. It wasn't too long before he heard the cross-talk ohomeoncel.. u,ing lhe eXlender, and he picked up len new code' in' ide ofa wcek! or course, he needed. working code to ,ign outo the Ihing in the first place, but ther••re ,orne eXlj:nders where you can "hold the line open" by hining ,orne key evory now and then. The nice thing about lhis kind of hacking i' that you oniy need to make one phone call to find things ou~ while standard backing require' a ,eparate phone call for each atlempl at a new code. No 'Jl'item in existence ""uld deteCl a fellow wilh·a tape recorder and a tone deCOder listeuingin, although it', cerlainly possible that someday, 'OmOOne eould design their phoue circuits 10 be 100% free of cross_tall:.. , That's all we ho" for nOW on the subject of garbage .picking. If you come up with any more place, where an inqui,itive person might find ,orne inleresting information lying .round. he. sure to write in and let Us kuow. Plea,e include your m'ethod of '"digging up~ the garbage, and ,uggestions to alltho'e other people out there who will try to duplicate your re,uits.
