The CIA is releasing instructions in Korean, Farsi, and Mandarin for informants in authoritarian regimes looking to communicate with the CIA in a safe way.

“People are trying to reach out to us from around the world and we are offering them instructions for how to do that safely,” the CIA wrote in a statement on Wednesday. “The security of those willing to reach out to us around the world is of paramount importance to us, and we want them to do so as safely as possible.”
