 "Greg Miller of The Washington Post reveals the hidden history of Crypto AG, a Swiss firm that sold encryption technology to 120 countries — but was secretly owned by the CIA for decades."

120 countries... experts😆 independently verified😆


 

 DAVIES: Wow. It's also remarkable, you learned in this material that you got access to, that that the German and American agencies brought in some corporate partners to help with the technology - Siemens in the case of the Germans, Motorola in the case of the Americans. Did these private companies know they were assisting in spying?

MILLER: Absolutely (laughter). I mean, there are detailed accounts in these documents of conversations with these massive companies. Hey, we are running this secret operation out of Switzerland. We're having trouble with this certain device. It's not working very well. We're trying to make our transition into a new technology. Can you help us out with this? They're may not be read into all the details of the operation, but they are - it's clear to those companies that they are working hand-in-glove with the CIA, NSA and the BND.
