It's all you, Stewie. This is from another forum, but I'll just quote the whole thing for you.
Quote:6.03.06- Back in the days of the Cold War, spies found ingenious and unusual ways to communicate with each other, hiding their communications in plain sight, whether encrypted or not. For instance, an intelligence agent (spy) might contact his case officer (handler) by placing an ad in the personals section of the local newspaper. This practice, it seems, continues today.
On or around May 8, the following personal ad appeared on the Internet classified ad site Craigslist. (It has since been removed.)
For mein fraulein
Mein Fraulein, I haven’t heard from you in a while. Won’t you
call me? 212 //// 796 //// 0735
If you actually called the number, up until a couple of days ago you would have heard this prerecorded message (MP3). It’s a head scratcher to keep you National Security Agency analysts occupied in your spare time. Each block of numbers is repeated twice; but below I have transcribed them only once for clarity.

You used to hear broadcasts not unlike this on shortwave radio all the time, stations which broadcast nothing but numbers all day. Nobody has yet come forward with an answer as to what exactly these stations were broadcasting, or to whom, or what was the point of the messages. If anyone does know, they likely can’t say because it’s classified information.
On or around May 12, Craigslist pulled the ad, but the number remained up and running, and someone tipped off our friends at 2600 Magazine. Its editor Emmanuel Goldstein mentioned the number on the May 24 episode (MP3) of the WBAI radio show Off The Hook. After that, it was flooded with calls from aspiring phone phreaks and other curiosity seekers, and that’s when some more of the details behind the number began coming out, through brute force, as it were.
The number is a VoIP setup from a small provider yet to be identified, but the wholesaler is a company called RNK Telecom. The account was prepaid, and the flood of calls after the radio show quickly depleted the account balance; callers over Memorial Day weekend would have heard a message (MP3) saying your account balance was too low. Now the number gives nothing but a busy signal.
Many questions remain, of course, now that the number seems to be no longer functioning. Who put the ad on Craigslist? What is the encrypted message? Is this all some sort of elaborate prank? Or could it be a viral marketing scheme of some type?
The question which most interests me, though, is what does the message mean? The Craigslist posting is typical of how intelligence agents might communicate in hostile countries where they are actively trying to evade the country’s intelligence services. The message at that phone number, though, seems like an easier avenue of attack for this particular problem, at least right now.
The first thing I notice is that it contains an unusually high number of zeros. And that’s just about where my cryptanalytic skills end. Anybody else want to take a crack at it?
