Operation Auroragold: How the NSA Hacks Cellphone Networks Worldwide

Ryan Gallagher, Operation Auroragold: How the NSA Hacks Cellphone Networks Worldwide. The Intercept, 4 December 2014. “According to documents contained in the archive of material provided to The Intercept by whistleblower Edward Snowden, the NSA has spied on hundreds of companies and organizations internationally, including in countries closely allied to the United States, in an effort to find security weaknesses in cellphone technology that it can exploit for surveillance.”

The documents also reveal how the NSA plans to secretly introduce new flaws into communication systems so that they can be tapped into—a controversial tactic that security experts say could be exposing the general population to criminal hackers.

Codenamed AURORAGOLD, the covert operation has monitored the content of messages sent and received by more than 1,200 email accounts associated with major cellphone network operators, intercepting confidential company planning papers that help the NSA hack into phone networks.

One high-profile surveillance target is the GSM Association, an influential U.K.-headquartered trade group that works closely with large U.S.-based firms including Microsoft, Facebook, AT&T, and Cisco, and is currently being funded by the U.S. government to develop privacy-enhancing technologies.

Karsten Nohl, a leading cellphone security expert and cryptographer who was consulted by The Intercept about details contained in the AURORAGOLD documents, said that the broad scope of information swept up in the operation appears aimed at ensuring virtually every cellphone network in the world is NSA accessible….

“Even if you love the NSA and you say you have nothing to hide, you should be against a policy that introduces security vulnerabilities,” Nohl said, “because once NSA introduces a weakness, a vulnerability, it’s not only the NSA that can exploit it.”…

The GSMA’s members include U.S.-based companies such as Verizon, AT&T, Sprint, Microsoft, Facebook, Intel, Cisco, and Oracle, as well as large international firms including Sony, Nokia, Samsung, Ericsson, and Vodafone….

According to Mikko Hypponen, a security expert at Finland-based F-Secure, criminal hackers and foreign government adversaries could be among the inadvertent beneficiaries of any security vulnerabilities or encryption weaknesses inserted by the NSA into communication systems using data collected by the AURORAGOLD project…. “When they start to introduce new vulnerabilities, it affects everybody who uses that technology; it makes all of us less secure.”
