Crypto AG - Back-doored Machines

Back-doored Machines

Crypto AG has been accused of rigging its machines in collusion with intelligence agencies such as the German Bundesnachrichtendienst (BND) and the United States National Security Agency (NSA), enabling such organisations to read the encrypted traffic produced by the machines. Suspicions of this collusion were aroused in 1986 following US president Ronald Reagan's announcement on national television that, through interception of diplomatic communications between Tripoli and the Libyan embassy in East Berlin, he had irrefutable evidence that Muammar al-Gaddafi of Libya was behind the 1986 Berlin discotheque bombing in which two US service personnel were killed and another fifty injured. President Reagan then ordered the bombing of Tripoli and Benghazi in retaliation. There is no conclusive evidence that there was an intercepted Libyan message.

Further evidence suggesting that the Crypto AG machines were compromised was revealed after the assassination of former Iranian Prime Minister Shahpour Bakhtiar in 1991. On August 7, 1991, one day before Bakhtiar's body was discovered, the Iranian Intelligence Service transmitted a coded message to Iranian embassies, inquiring "Is Bakhtiar dead?" Western governments were able to decipher this transmission, causing Iranian suspicion to fall upon their Crypto AG equipment.

The Iranian government then arrested Crypto AG's top salesman, Hans Buehler, in March 1992 in Tehran. It accused Buehler of leaking their encryption codes to Western intelligence. Buehler was interrogated for nine months but, being completely unaware of any flaw in the machines, was released in January 1993 after Crypto AG paid a $1m ransom to Iran. Soon after Buehler's release Crypto AG dismissed him and charged him the $1m. Swiss media and the German magazine Der Spiegel took up his case in 1994, pursuing the question of whether Crypto's machines had in fact been rigged by Western intelligence.

Crypto AG rejected these accusations as "pure invention", asserting in a press release that "in March 1994, the Swiss Federal Prosecutor's Office initiated a wide-ranging preliminary investigation against Crypto AG, which was completed in 1997. The accusations regarding influence by third-parties or manipulations, which had been repeatedly raised in the media, proved to be without foundation.". Subsequent commentators are unmoved by this denial, stating that it is likely that Crypto AG products were indeed rigged.
