The Great SIM Heist

American and British spies hacked into the internal computer network of the largest manufacturer of SIM cards in the world, stealing encryption keys used to protect the privacy of cellphone communications across the globe, according to top-secret documents provided to The Intercept by National Security Agency whistleblower Edward Snowden.

The hack was perpetrated by a joint unit consisting of operatives from the NSA and its British counterpart Government Communications Headquarters, or GCHQ. The breach, detailed in a secret 2010 GCHQ document, gave the surveillance agencies the potential to secretly monitor a large portion of the world’s cellular communications, including both voice and data.

With these stolen encryption keys, intelligence agencies can monitor mobile communications without seeking or receiving approval from telecom companies and foreign governments. Possessing the keys also sidesteps the need to get a warrant or a wiretap, while leaving no trace on the wireless provider’s network that the communications were intercepted. Bulk key theft additionally enables the intelligence agencies to unlock any previously encrypted communications they had already intercepted, but did not yet have the ability to decrypt.

As part of the covert operations against Gemalto, spies from GCHQ — with support from the NSA — mined the private communications of unwitting engineers and other company employees in multiple countries.

“It’s unbelievable. Unbelievable,” said Gerard Schouw, a member of the Dutch Parliament, when told of the spy agencies’ actions. Schouw, the intelligence spokesperson for D66, the largest opposition party in the Netherlands, told The Intercept, “We don’t want to have the secret services from other countries doing things like this.” Schouw added that he and other lawmakers will ask the Dutch government to provide an official explanation and to clarify whether the country’s intelligence services were aware of the targeting of Gemalto, whose official headquarters is in Amsterdam.

Last November, the Dutch government amended its constitution to include explicit protection for the privacy of digital communications, including those made on mobile devices. “We have, in the Netherlands, a law on the [activities] of secret services. And hacking is not allowed,” Schouw said. Under Dutch law, the interior minister would have to sign off on such operations by foreign governments’ intelligence agencies. “I don’t believe that he has given his permission for these kind of actions.”

Top-secret GCHQ documents reveal that the intelligence agencies accessed the email and Facebook accounts of engineers and other employees of major telecom corporations and SIM card manufacturers in an effort to secretly obtain information that could give them access to millions of encryption keys. They did this by utilizing the NSA’s X-KEYSCORE program, which allowed them access to private emails hosted by the SIM card and mobile companies’ servers, as well as those of major tech corporations, including Yahoo! and Google.
