You know you're #OldSchool when you see a phone number on a CV and immediately go "oh 317, they're from Indiana". #phreak #geek #infosec

Woohoo! I now own the right vintage kit to operate an AC-14 signalling link (UAX “out of area” exchange lines)

This signalling system relied on in-band 2280Hz tones, and although its design wasn’t quite as open to abuse as the American 2600Hz equivalent signalling, this equipment did have vulnerabilities

So, once I’ve got it working in captivity I intend to have lots of fun trying to #phreak it!

> "Phreaking" is what a "Phreak" does. In the 1960s, groups of hippies, radicals, etc., bored with the middle and upper class successes of their famllies, engaged in wild, daring, and dangerous activities. These activities included ripping-off (originally a hippie term) Ma Bell by making free long distance and pay phone calls, using home-built handheld Blue and Red boxes, respectively. These perpetra-tors become known as "Phone Freaks," and later, as "Phreaks."

Hello phreaks and hackers! I just fully modernized my python blue box DTMF tone generator, apparently someone was actually using it :blobcatawauu: check it out! https://github.com/zeyus/Python3BlueBox

I used to know a phone phreak / hacker who went by the alias “Spock” from Minnesota. Has anyone run into them, I suspect they moved out of Minnesota years ago.

How cool. @2600 has their 1984 publication year book-a-fied. I've been a subscriber off/on since late 80's. Articles on phreaking, hacking, and hacker culture. In the latest edition (delivered today) publications like 2600 are having a hard time publishing paper editions. costs, independent bookstores closing, COVID, and Amazon eliminating their magazine subscriptions. Figured I would help by buying a few back-issues.

It began in the mid 1960's when telephone companies around the world took part in a multibillion dollar conversion of their equipment.

The new system was based on twelve different tones, and operators almost anywhere in the world could control telephone equipment virtually anywhere by using combinations of these same twelve tones.

Following on from yesterdays discussion of #telephone signalling, I've just tripped over this PDF copy of "Telecomunications Instruction A5 A0011" from 1979

Which is a document from the Post Office in the UK that describes various signalling protocols in use on the #phone network at that time

#phreak so cute!☎️​

Years ago after dumpster diving for passwords and making red boxes and war dialing and bouncing COCOT's to get to voice bridges and logging onto local BBS's full of warez and Phrack issues and Defcon announcements back when ITAR and PGP where hot topics we would play this game.

That group of people ultimately got me starting having hacker coffees and then to Decon 4.

I just bought this and its It's like getting into a time machine into my teens.

I've learned a few good things about payphones in the US, UK, and Canada, including relearning my old knowledge of red boxes, and the tones that are used to spoof payphones into thinking which coins have been inserted.

US payphones use dual frequency tone signals at 1700 Hz for the first signal, and 2200 Hz for the second. A 66ms pulse indicates a nickel; two 66ms pulses with a pause of 66ms between each is a dime; 5 rapid 33ms pulses with 33ms pauses in between each is a quarter.

Canada only uses the 2200 Hz frequency (AFAIK), with the same timing as US payphones for each coin.

The UK used a 1000 Hz tone, at 200ms for a 10p piece, and 350ms for a 50p piece.

The ones I'm curious about now, and I can't seem to find much info on, are Japanese payphones. They're still quite the enigma to me, and I'm curious to know about how the old phone system in Japan worked, what tones were used to indicate coin insertion on payphones, and if it was possible to phreak their phone system, and if anyone ever did.

Has anyone ever found anything good or juicy about the Japanese phone system?
