This is one of the coolest things I’ve learned recently: Foreign intelligence agencies still use good ol’ radio to share top secrets. Even with all the powerful tech at their fingertips, radio use in espionage has actually gone up in popularity since the 2010s. Pretty wild.

Russia in particular loves this technique. Why? Intelligence agencies don’t trust the internet. Makes sense.

📻 Spy-Fi: The original wireless network

Foreign agencies have been using shortwave radio frequencies to broadcast coded messages for decades. 

Starting in the mid-1960s, if you tuned your radio to shortwave frequencies between 5.422 and 16.084 megahertz (MHz), you might hear music … or you might hear a woman’s voice with an English accent reading number combinations. 

The U.K.’s MI6 intelligence agency and other spy networks used these “number stations” until at least 2008 to talk to operatives in the field. Whoa.

🤫 All secrets, all the time

This tactic is still very much alive and well. In 2020, the FBI discovered messages being sent to Russian deep-cover officers living in Massachusetts. Last year, researchers caught Russia’s foreign intelligence agency, SVR, broadcasting a test transmission in French. 

But it’s not just Russia. Taiwan is active now. The “Star Star” station (V13) broadcasts coded messages to agents in mainland China, complete with flute music intros.

So, what’s the advantage? Even encrypted phones can be hacked. It’s also easier than ever to plant spyware on a device.

☝️ The secret’s in the signal

In each broadcast, the sender and receiver use what’s called a “one-time pad” to encrypt and decrypt the message. It’s basically a matching list of random numbers, no fancy spy gear required.
