Flccrec Service and the FRT in an e-IToil [ocnleli people passing

M ike Wendland of WDIV-TV in Detroit thought the board 
wou Id be li good way to get hack ground for a story on hackers, 
So, for si\ weeks he operated Li BRS on John Mayfield's

fix; buord had virtually unlimited disk storage and a variety 
of phone lines. But it all began to crumble as an anonymous 
hacker figured out what the true purpose of the boa i d was and 
who I he opd ? 1 ors. were. Word sprCLid quickly and the 
operators decided 1o “come clean” (see below}. 

Despite the threatening tone of WDIVs message below. 
Wend hind says he wi 1 1 not turn an y names in 1o the auebn ritics, 
but lie will do a story about the information that was posted 
This will include credit card numbers. cocks. passwords. etc. 
The purpose, lie claims, is. to “show l hat it [1 his kind of info] is 
si ill out there. 1 ' 

Wend land will do three stories, airing in mid-October. He 
will use handler in his report, not tftil names Tie plans to talk 
about “how people profit at Ihe expense of hackers. .. . H ackei's 
are Tien bad guys, hy aiul large, 1 ' he says. 

[ hat’s true; they’re not. And, as far as we can IcLL. no actual 
crime was committed by any of tlte iisem. Yet lheir mailbox^

eke Iron sc, somehow it didn't otursLituLe ti violation of their 
privacy, in these days of curtailed freedoms, where magazines 
a i e pulled of! shelves i n 7-1 1 ’s for eve ryonc 's good , where d mg 
and lie delector tesLs are as “necessary” as spelling quizzes, 
where onr numbers have become our names, it’s more than a 
IrifLe unsettling that Lhere is another moralistic sel of eyes 
watch in gall of us, judgi ng ou r words. misreading the lacrs. You 
come to expect this son of thing from die government, bui 
when a TV repo rlei begins 1o play cop . judge, and jury. tt>i time

Dear LPt 

As most of the COnseifiux, wt.trltj already /;n(- | n , -V, Cupt/fm 
Midnight has been found. (This letter was received before that 
happened. ) He was .'ri Florida as it turned mu, but it sure was 
intereSihtg how everyone seemed io think he has it; Texas — 
probably a trick by the feds. 

Official ground .-nations hove unique informal i<m contained 
within l heir signals, and the fettering used in the message 
narrowed the starch even further. Hut generic equipment has 
no such information and frankly, wear? v^rp surprised Qt how 
easy intercept tot t and t'ot/troi of the viufiows serviees seems to 
he- Anyone with ft receiving dish tan modify their equipment to 
for under $ 11)00. if they know u hat signals so send ansi where hi 
send them, complete pandemonium is theirs. We're very 
surprised that more incidents haven V been occurring. 

We do want to know tit ore about satellites — it's one of the 
topics were expanding into. We have added a satellite stth- 
bodrd to The Private Sector (2011664471 janrf wf welcome rmy 
information any of our readers can rm-ttrihme.

Dear LCCI ULi 

ft sounds fikeynu picked the right magazine. We update info 
as '.l( j get infe\ ju keep reading. 

Some areas are expettntenuni; wfr/i number identification — 
k rtitwing w ho 's railing you before you pick up. This is already j'ri 
pface within major corporations and institutions.: n ■' only a 
matter of time before owry call is identified. 

Tf;c best way to get a CNf A fen an unlisted number is h.i call 
it , then ask your local business offset' why that number showed 
up on your hid. They 'll cheer dy fell vow all about it. 

PREFIX If, if we understand your question, ihe three digits 
before the dash in your phor te number. Our phono number is 
( 516 ) 7.Aj'-I , oii'jij. Our prefix Is ?Sl. Our urea code, or NBA, is 
5/d. and our extension is 760 ft. 

Wt f hopa readers wifi send reviews of now pay phones that 
show up in their area. Home of them really rip yon off others 
let you get away with murder. Be careful though— if you 're 
playing with one of the Sc phones,. odds are that the person who 
owns it A in the same rt.tt.tmf 
D+yvr 

J have recently gained Severn] numbers in several I different 
prefixes in my urea that get 41 strange response. [ have lonkcd 
around, and found a tew references ton few of 1 hose numbers,

Dear Jh": 

SI.-l )s a phone system put out by Northern Telecom, h 's 
starting fa gel old and outdated and many of its users are 
dissatisfied with it. You dhin "l fell us if the strange responses 
you're receiving are voice or data lines. Either way r it's 
something interna! to the system and the peuenfia! for abuse 
and manipulation certainly exists. 

Dear 

E would Like to open by Miying how much 1 enjoy your 
newsletter, More people should taken stand and publish wliat 
they think is right, as you folks do. Keep up the good work! 

[ am curious about the rules regard ing cancellation of 
charges for Long distance calls to a wrong number. J'n the past, 
when o call has nut gur.e through correctly. I've called the 
AT&T operator immediately a nd site kis cancelled the charges. 
Ry whal Criterion do they judge whether or not the call was in 
fact a wrong number? 1 s it duration of tlte Call? Do they verify 
that you actually do place a Cull Lothe teorrect ’ number after 
reporting the error? All this is prompted by the numerous times 
E pliice long distance culls and end up leaving the same message 
On the same answering machine when awniliog a friend tu get 
home. 

Thanks! 

Friends in faraway places 

I tear Frirnthn 

JFe assume they take a good look at how many requests for 
credit you make. If you make more than a couple, especially to 
the same number, they will certainly begin asking questions. It s 
a great i*vry to get even with pcopic—ftiss moke hundreds of 
requests of credit to their tmmltcrf (We do NOT endorse this 1 } 

Hopefully, our A T& T friends will write to us w ith the exact 
procedure when credit is given.
