Revealed: the machine that spied for America
Was this the greatest intelligence coup ever? A coding device that was used for decades by scores of countries has been exposed as an American trick to read all their top secret messages.
For the Libyan dictator Colonel Gaddafi, 15 April 1986 was one of the grimmest days of his life.
American bombers had just launched an attack on his country – among the 40 casualties was his daughter Hana. The strike was in retaliation for the deaths of two US soldiers in a Berlin nightclub, where his agents had planted a bomb. But how had the Americans worked out that he was responsible?
The answer, according to an article today in the Washington Post, lay in a coding machine called H-460 used by Libyan intelligence.
Invented by a Swiss company, Crypto, it was supposed to make every message indecipherable. But Crypto was secretly owned by the CIA and the West German government, that could easily unscramble what was said. When the Libyan agents reported triumphantly on their mission, the CIA had irrefutable proof of their guilt.
The Libyans were not the only ones being spied on through Crypto. Over a period of 50 years, its machines were sold to 120 governments.
They included long-standing enemies of the US, such as Iran, but also Nato allies, such as Spain. In the 1980s, around 40% of all messages decoded by US intelligence were collected in this way.
Crypto was founded by Boris Hagelin, a Russian who fled to the US in the 1940s and invented a portable encryption machine for use by American troops. When, after World War Two, he moved to Switzerland and started producing more sophisticated machines, the Americans persuaded him to sell them only to friendly countries.
But in the mid-1960s, they went further. Hagelin agreed that the new H-460 machine could be designed by US intelligence. While it appeared to produce randomly generated characters, it actually repeated itself in a way which allowed those who knew its secret to decode them easily.
“Talk about a brave new world!” a secret CIA document declared.
America’s greatest enemies, the USSR and China, were too suspicious of Crypto to buy its machines – but the US found out a lot about them from countries who were friendly with them and did use H-460. Britain also benefited, particularly during the Falklands Crisis, when the US passed on messages intercepted from Argentina.
In the long and tangled history of spying, is this quite simply the greatest intelligence coup ever?
Some say that no spymaster could ask for a better tool. To be able to read an enemy’s most secret messages for decades, without them knowing, is what every intelligence service dreams of. America’s record of spying on Iran in the 1980s – decoding up to 90% of its communications – has surely never been equalled. The CIA also made millions of dollars to fund its activities from selling H-460s.
Others point out that there have been equally spectacular intelligence coups. In WW2, breaking Germany’s Enigma code gave Britain and her allies an advantage which may have changed the course of the war. And after the war, the Soviet Union was able to develop its nuclear-weapons programme much faster than expected thanks to secret documents obtained by spies such as John Cairncross and Klaus Fuchs.
- If you were called upon to serve your country as either a soldier or a spy, which would you choose?
- Is spying wrong?
- Divide into pairs. Agree on a code in which each letter of the alphabet corresponds to a different one. Write a three-sentence message in the code, warning your partner that the enemy is on their trail. Then swap your messages and decode them.
- Imagine you are the new owner of Crypto. On one side of paper, write a letter to your customers to say that you are sorry that they have been spied on but hope they will continue to buy your equipment.

Q & A
- What do we know?
- Selling Crypto’s machines to unsuspecting governments made it possible for America and West Germany to decode a huge number of secret messages, over half a century. It allowed the US to follow the Iranian government’s thinking during the 1979 hostage crisis, and identify Libya as the country behind the Berlin nightclub bombing. Although some countries had suspicions about Crypto, the operation was not exposed and only abandoned as a result of new technology overtaking the H-460.
- What do we not know?
- Whether the operation collected more important information than some of the other great intelligence coups, such as the breaking of the Enigma code. We don’t know how well the intelligence gathered was used. Or how badly the discovery of the plot will affect America’s relationship with the supposedly friendly countries it spied on, such as Spain and Italy. It is uncertain if China will be able to achieve similar results by selling the Huawei 5G system to other countries.
