Crypto AG, a Swiss company that sold encryption machines to over 120 countries, was secretly owned by the CIA and German BND since 1970. For half a century, foreign governments paid good money for equipment that allowed American and German intelligence to read their most sensitive communications. A CIA internal report called it 'the intelligence coup of the century.'
“Foreign governments paid for the privilege of having their secrets read.”
From “crazy” to confirmed
The Claim Is Made
This is the moment they called it crazy.
For fifty years, one of the world's most trusted encryption companies sold its products to over 120 countries—governments that believed they were protecting their most sensitive secrets. What they didn't know was that every message encrypted by Crypto AG's machines could be read by American and German intelligence agencies. The company they trusted wasn't independent at all. It was owned by the CIA.
The Swiss company Crypto AG marketed itself as a neutral provider of cryptographic equipment to nations worldwide. Governments from allies to adversaries purchased their machines to safeguard military communications, diplomatic cables, and intelligence operations. No one questioned the company's legitimacy. It was based in a neutral country, staffed by respected engineers, and had built a reputation over decades. The encryption it sold was genuinely sophisticated. But there was a fatal flaw that only two intelligence agencies knew about.
The CIA acquired its stake in Crypto AG in 1970, partnering with the German BND. From that moment forward, the two intelligence services possessed a master key to communications that they weren't supposed to access. They knew what foreign governments were planning, where their armies were moving, and what their diplomats were negotiating. The arrangement was so successful that the CIA later called it "the intelligence coup of the century" in internal documents.
For decades, this operation remained completely hidden. Crypto AG continued selling its machines as if nothing unusual was happening. Governments continued buying them, confident they were secure. The company's executives who weren't read into the secret had no idea they were running an intelligence operation disguised as a private business.

Confirmed: They Were Right
The truth comes out. Officially documented.
Confirmed: They Were Right
The truth comes out. Officially documented.
The truth only emerged in 2020, when the Washington Post published an investigation based on newly declassified CIA documents and interviews with former intelligence officials. The Post obtained actual CIA records describing the operation in detail, including how the agency monitored communications from countries including Iran, Libya, and Pakistan. The reporting confirmed what had long been rumored in intelligence circles but never proven with documentary evidence.
The response from intelligence agencies was notably muted. Neither the CIA nor the BND issued vigorous denials. Instead, they offered measured statements acknowledging that the operation had been important for national security. There was no real attempt to claim the stories were false. The agencies knew the evidence was too solid to contest.
This case reveals something uncomfortable about the relationship between governments and technology companies. It shows that intelligence agencies will exploit trust when they believe it serves national security interests. It demonstrates that encryption—the very tool meant to protect secrets—can be compromised at the source, before users ever have a chance to rely on it. Most troubling, it illustrates how thoroughly a secret of this magnitude can be kept for decades.
The implications extend beyond the Cold War era when Crypto AG operated. If intelligence agencies have done this once, what prevents them from doing it again? Which technology companies today might be secretly compromised? The Crypto AG operation proves that extraordinary deception in service of intelligence gathering isn't theoretical. It happened. It was called the intelligence coup of the century for a reason.
