Numbers Stations Move From Shortwave To VoIP

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?"

why not use png texting?

[plasmacutter]

there is a flaw in the png format which allows you to embed random crap in png files.

the particular application i've seen commonly practiced was mp3 pngs, you download the file, rename it .mp3, and can load it straight into winamp.

why not embed a special encrypted text format into a png file, and build a special app specifically for viewing the format.

unlike mp3 pngs, it would be very hard to detect, especially on huge imageboard sites like 4chan's /b/ board Oo.
