The National Security Agency and the FBI are tapping directly into the central servers of nine leading U.S. Internet companies, extracting audio, video, photographs, e-mails, documents and connection logs that enable analysts to track a person’s movements and contacts over time.
What has the government been doing? Is it legal? Does it mean some bureaucrat somewhere has heard all your phone calls? Read on to find out.
Government officials declined to comment for this story.
Roots in the ’70s
PRISM is an heir, in one sense, to a history of intelligence alliances with as many as 100 trusted U.S. companies since the 1970s. The NSA calls these Special Source Operations, and PRISM falls under that rubric.
The Silicon Valley operation works alongside a parallel program, code-named BLARNEY, that gathers up “metadata” — address packets, device signatures and the like — as it streams past choke points along the backbone of the Internet. BLARNEY’s top-secret program summary, set down alongside a cartoon insignia of a shamrock and a leprechaun hat, describes it as “an ongoing collection program that leverages IC [intelligence community] and commercial partnerships to gain access and exploit foreign intelligence obtained from global networks.”
But the PRISM program appears more nearly to resemble the most controversial of the warrantless surveillance orders issued by President George W. Bush after the al-Qaeda attacks of Sept. 11, 2001. Its history, in which President Obama presided over “exponential growth” in a program that candidate Obama criticized, shows how fundamentally surveillance law and practice have shifted away from individual suspicion in favor of systematic, mass collection techniques.
A ‘directive’
Formally, in exchange for immunity from lawsuits, companies like Yahoo and AOL are obliged to accept a “directive” from the attorney general and the director of national intelligence to open their servers to the FBI’s Data Intercept Technology Unit, which handles liaison to U.S. companies from the NSA. In 2008, Congress gave the Justice Department authority to for a secret order from the Foreign Surveillance Intelligence Court to compel a reluctant company “to comply.”
In practice, there is room for a company to maneuver, delay or resist. When a clandestine intelligence program meets a highly regulated industry, said a lawyer with experience in bridging the gaps, neither side wants to risk a public fight. The engineering problems are so immense, in systems of such complexity and frequent change, that the FBI and NSA would be hard pressed to build in back doors without active help from each company.
Apple demonstrated that resistance is possible, for reasons unknown, when it held out for more than five years after Microsoft became PRISM’s first corporate partner in May 2007. Twitter, which has cultivated a reputation for aggressive defense of its users’ privacy, is still conspicuous by its absence from the list of “private sector partners.”
“Google cares deeply about the security of our users’ data,” a company spokesman said. “We disclose user data to government in accordance with the law, and we review all such requests carefully. From time to time, people allege that we have created a government ‘back door’ into our systems, but Google does not have a ‘back door’ for the government to access private user data.”
Like market researchers, but with far more privileged access, collection managers in the NSA’s Special Source Operations group, which oversees the PRISM program, are drawn to the wealth of information about their subjects in online accounts. For much the same reason, civil libertarians and some ordinary users may be troubled by the menu available to analysts who hold the required clearances to “task” the PRISM system.
There has been “continued exponential growth in tasking to Facebook and Skype,” according to the 41 PRISM slides. With a few clicks and an affirmation that the subject is believed to be engaged in terrorism, espionage or nuclear proliferation, an analyst obtains full access to Facebook’s “extensive search and surveillance capabilities against the variety of online social networking services.”
According to a separate “User’s Guide for PRISM Skype Collection,” that service can be monitored for audio when one end of the call is a conventional telephone and for any combination of “audio, video, chat, and file transfers” when Skype users connect by computer alone. Google’s offerings include Gmail, voice and video chat, Google Drive files, photo libraries, and live surveillance of search terms.
Firsthand experience with these systems, and horror at their capabilities, is what drove a career intelligence officer to provide PowerPoint slides about PRISM and supporting materials to The Washington Post in order to expose what he believes to be a gross intrusion on privacy. “They quite literally can watch your ideas form as you type,” the officer said.
