British spies use wireless "drop rocks" to exchange info with Russians

Those crafty British folk, they're always up to something. The L.A. Times is reporting that Moscow has recently
"outed" a British spy ring doing business with Russian double-agents, transferring information and channeling funds to strictly-monitored human-rights groups. Normally this type of story isn't our cup of tea, so to speak, but these real-life James Bonds were exchanging data in a method that piques our interest: they were using fake rocks to wirelessly make and receive information drops to and from their Russian associates. Apparently these spy rocks have a range of about 80 feet and only require a few seconds to make an entire data handoff. No word, though, on which wireless standard was being used (if any), or what type of encryption was solid enough for this case of international espionage.
