Numbers Stations Move From Shortwave To VoIP 228

IO ERROR writes "For decades, intelligence agencies have been sending secret messages to their agents in the field using shortwave numbers stations broadcasting encrypted messages for all to hear and puzzle over. Now someone is putting numbers stations on VoIP telephone numbers for anyone to call, and posting messages to Craigslist to alert the recipients to the existence of their messages. One of them went up last month and now a second one has appeared. Will there be a third? Who's behind them? And can you crack the code?"

    They have been an oddity until now, but hearing about these numbers stations makes me think our very own slashdot is being used as a covert channel.

    Certainly piqued my curiosity more than once, it would be good to get to the bottom of it.

    Couple of examples here [slashdot.org] and here [slashdot.org], I've seen a few more, but they get lost quickly due to moderation.
    The second one I posted has a bit of info about its origins here and links to a user and an apparent initial source of the messages.

    From one of the articles: "Update: Ryan Singel (of Wired) thinks it's just two young cryptanalysts in love, "sending love notes and taunting Mossad, the NSA and the phone phreakers at the same time." He also points to some links indicating those shortwave numbers stations are still around. Go take a listen."

    Cool. Not everyday you learn about an international conspiracy to broadcast numbers. If it were me, I would set up one of these to broadcast from SEALAND!!! http://en.wikipedia.org/wiki/Sealand [wikipedia.org]

    True enough, but I can steal your mobile and call that number. Then when the Suede Denim Secret Police come knocking they sure won't be knocking on my door.

    The other problem is that shortwave radio recievers are incriminating devices in some dark places that you would want to have spies in. Cell phones pretty much universally are not.

    Thats why the choice of VOIP is so odd, because although it does provide easy access, the prepaid account was emptied, meaning that its no longer accessible.

    So its not the best way of doing it if you are really trying ot create a secure comms network. What would be better (though just as traceable) would be posting here, like first post said.

    but the shortwave system still trumps it.

    Lets analyse it:
    What do you want from a secure comms network aimed (as these are supposedly meant to be) at undercover agents
    1. Untraceable to the sender
    2. Untraceable to the reciever
    3. Universally Accessible
    4. Undecodable

    So we need something that is hard to find, easy to access and secure but hard to trace. Using something as logged and monitored as the internet would probably be a bad decision unless you use something like a coin operated internet kiosk to post and to retrieve, making it less accessible (in the here and now sense, a radio can arguably recieve information anywhere).

    So why leave shortwave?
    You wouldnt.

    Thus this is probably a hobbyist, or a practical joker, or a viral marketing meme, or an elaborate hoax.

    Such messages also appear to be manifesting themselves as blog comment spam [boingboing.net].

    The numbers are always in 5 digit blocks too, just like the ones that another poster observed occuring here on slashdot [slashdot.org].

    This is either genuinely weird, or just someone playing an elaborate prank.

    Still, number stations are pretty much a one way means of communication. The whole idea behind them is that they can be broadcast from a secure location (ie, from the territory of the state running the agents), and received by any number of recipients, without anyone being able to detect the fact that the transmission was received. In case of voip, both sides are detectable - even if not eaisly traceable.

    Also, the VoIP method is missing another point of the stations: with a radio station, you can remain tuned for as long as you wish, without the risk of detection increasing. Staying connected to a "number station" via VoIP means that you have to stay connected for prolonged amounts of time, increasing chances of detection, if only by a hotel employee who notes that someone was sitting on the hotel's wifi network for 24 hours. Besides, if one wants to use "number stations" over the Internet, one can simply post the numbers in any amount of places. It is easier and probably also safer to grab one text file off some FTP server, than it is to stay connected somewhere for a longer time. You might not get the message as fast then, but at least you're not sitting in a van next to your local Motel 6 for 3 days.

    Could it be that on Lost the radio broadcast is a play on the Number Stations stuff?

    I am a bit behind on Lost because I live in Australia so I may be behind on the current theories.

    They have been an oddity until now, but hearing about these numbers stations makes me think our very own slashdot is being used as a covert channel.

    Or it's just a creative troll, hoping someone will spend hours or days trying to figure out meaning behind what's really just the numeric output of /dev/random or something.

    I've honestly always though "number stations" were pretty much the same thing...someone having their jollies. Has anyone actually tried to get a fix on them? I thought HAMs loved doing "hunts"...why don't they do a "hunt" on some number stations some time?

    I bought a 4 (or maybe 6?) CD set of numbers stations recordings several years ago, call The Conet Project. Since i'm big into experimental music, the idea intrigued me. While some of the recordings were downright spooky and disturbing (not necessarily a bad thing), I found it mostly to be soothing in a weird way (though after listening to 2 or 3 CDs of these recordings non-stop, it started getting a bit ... too weird).

    You are thinging traditional VOIP subscriber. Buy an adaptor at ______ with cash. Activate it with a stolen card and ID. Hook it directly to a wireless access point in client mode. Wardrive near hotels. Park nearby for a couple days.

    So, basically, instead of using a fairly innocuous radio, which is easy to explain away if apprehended, you propose that the secret agent go around carrying stolen cards and stolen ID and wardrive? I think the general idea is for spies to not call attention to themselves, and engaging in two or three activities that might be illegal even if not connected with spying is probably not the best procedure!

    It's much harder to pinpoint the source than a radio signal. RF Direction equipment can triangulate a HF signal quite quickly.

    The numbers stations broadcast on shortwave frequencies whose signals carry very far, with plenty of bounces off the ionosphere. You can triangulate them to approximately what quarter-hemisphere they come from. And even if the exact location were found, it wouldn't help catch the spy receiving the signal, nor even give any indication that the signal is for a spy in your country.

    There's something fishy about these messages.
    Have you noticed that every group is sent twice? That would make a lot of sense if you were transmitting over the radio, because a group might arrive garbled. Posting each group twice on slashdot, however, makes no sense. The message will arrive correctly every time.

    The first message was was listed in the the New York classifieds. Now it is possible the author simply placed it there for obscurity reasons, but it could also be that he/she was targetting someone who resides specifically in New York. Also, area code 212 is in New York City, which could be so their contact in New York wouldn't have to dial long distance to reach it.

    The second message was in the San Francisco classifieds, and there too the area code, 415, of the number matches with the city. It could be that the author of the message is trying to make it easier on their contacts in those specific areas, as dialing local does not leave nearly as much of a trace as dialing long distance.

  • I am a huge Numbers Station geek, and I've been known to listen to the Conet Project just for fun at parties, shortly before I'm asked to leave. So I've been following this story on the Spy Numbers mailing list for at least two weeks, now. If you're intrigued by this mystery, you will probably love the resources at SpyNumbers.com, or the Enigma2000 group at Yahoo.

    Anyway, my prediction: The next message will be posted on Craigslist for Boston. The first message announced Group 415, and the second message was posted on Craigslist for San Francisco.

    The second message announces group 617, which means the next message will probably show up on Craigslist for Boston. If that proves to be true, it is 99% certain that this is just a prank, or something being done by amateurs having a bit of fun. There's no way a real spook or someone sending messages of any importance would use a scheme that some piker like me can figure out.

    So what's going on here? Eh. If there's anything really in there, now that it's been on Slashdot and boingboing, it's quite likely to be cracked within a few days, unless it's encrypted with a one time pad. Whatever it is, part of me is afraid that it's part of that stupid DaVinci Code promotion, and the same part of me hopes that it's somehow related to the Hanso Foundation.

    No, they're not somebody trolling the airwaves, most governments are very careful to whom they issue SW broadcasting licenses, and anyone pulling stunts like that would have them revoked in a flash.

    As another poster said one of the most infamous numbers station, the Lincolnshire Poacher, has been traced to an RAF base in Cyprus and a number of others have been triangulated, all of them leading to some sort of military or security service base.
