An American organization founded by tech giants Google and IBM is working with a company that is helping China’s authoritarian government conduct mass surveillance against its citizens, The Intercept can reveal. The OpenPower Foundation — a nonprofit led by Google and IBM executives with the aim of trying to “drive innovation” — has set up a collaboration between IBM, Chinese company Semptian, and U.S. chip manufacturer Xilinx. Together, they have worked to advance a breed of microprocessors that enable computers to analyze vast amounts of data more efficiently. Shenzhen-based Semptian is using the devices to enhance the capabilities of internet surveillance and censorship technology it provides to human rights-abusing security agencies in China, according to sources and documents. A company employee said that its technology is being used to covertly monitor the internet activity of 200 million people. Semptian, Google, and Xilinx did not respond to requests for comment. The OpenPower Foundation said in a statement that it “does not become involved, or seek to be informed, about the individual business strategies, goals or activities of its members,” due to antitrust and competition laws. An IBM spokesperson said that his company “has not worked with Semptian on joint technology development,” but declined to answer further questions. A source familiar with Semptian’s operations said that Semptian had worked with IBM through a collaborative cloud platform called SuperVessel, which is maintained by an IBM research unit in China.

Sen. Mark Warner, D-Va., vice chair of the Senate Intelligence Committee, told The Intercept that he was alarmed by the revelations. “It’s disturbing to see that China has successfully recruited Western companies and researchers to assist them in their information control efforts,” Warner said. Anna Bacciarelli, a researcher at Amnesty International, said that the OpenPower Foundation’s decision to work with Semptian raises questions about its adherence to international human rights standards. “All companies have a responsibility to conduct human rights due diligence throughout their operations and supply chains,” Bacciarelli said, “including through partnerships and collaborations.” Semptian presents itself publicly as a “big data” analysis company that works with internet providers and educational institutes. However, a substantial portion of the Chinese firm’s business is in fact generated through a front company named iNext, which sells the internet surveillance and censorship tools to governments. iNext operates out of the same offices in China as Semptian, with both companies on the eighth floor of a tower in Shenzhen’s busy Nanshan District. Semptian and iNext also share the same 200 employees and the same founder, Chen Longsen. After receiving tips from confidential sources about Semptian’s role in mass surveillance, a reporter contacted the company using an assumed name and posing as a potential customer. In response, a Semptian employee sent documents showing that the company — under the guise of iNext — has developed a mass surveillance system named Aegis, which it says can “store and analyze unlimited data.” Aegis can provide “a full view to the virtual world,” the company claims in the documents, allowing government spies to see “the connections of everyone,” including “location information for everyone in the country.” The system can also “block certain information [on the] internet from being visited,” censoring content that the government does not want citizens to see, the documents show.

Chinese state security agencies are likely using the technology to target human rights activists.

Aegis equipment has been placed within China’s phone and internet networks, enabling the country’s government to secretly collect people’s email records, phone calls, text messages, cellphone locations, and web browsing histories, according to two sources familiar with Semptian’s work. Chinese state security agencies are likely using the technology to target human rights activists, pro-democracy advocates, and critics of President Xi Jinping’s regime, said the sources, who spoke on condition of anonymity due to fear of reprisals. In emails, a Semptian representative stated that the company’s Aegis mass surveillance system was processing huge amounts of personal data across China. “Aegis is unlimited, we are dealing with thousands Tbps [terabits per second] in China more than 200 million population,” Zhu Wenying, a Semptian employee, wrote in an April message. There are an estimated 800 million internet users in China, meaning that if Zhu’s figure is accurate, Semptian’s technology is monitoring a quarter of the country’s total online population. The volume of data the company claims its systems are handling — thousands of terabits per second — is staggering: An internet connection that is 1,000 terabits per second could transfer 3.75 million hours of high-definition video every minute. “There can’t be many systems in the world with that kind of reach and access,” said Joss Wright, a senior research fellow at the University of Oxford’s Internet Institute. It is possible that Semptian inflated its figures, Wright said. However, he added, a system with the capacity to tap into such large quantities of data is technologically feasible. “There are questions about how much processing [of people’s data] goes on,” Wright said, “but by any meaningful definition, this is a vast surveillance effort.” The two sources familiar with Semptian’s work in China said that the company’s equipment does not vacuum up and store millions of people’s data on a random basis. Instead, the sources said, the equipment has visibility into communications as they pass across phone and internet networks, and it can filter out information associated with particular words, phrases, or people. In response to a request for a video containing further details about how Aegis works, Zhu agreed to send one, provided that the undercover reporter signed a nondisclosure agreement. The Intercept is publishing a short excerpt of the 16-minute video because of the overwhelming public importance of its content, which shows how millions of people in China are subject to government surveillance. The Intercept removed information that could infringe on individual privacy.

The Semptian video demonstration shows how the Aegis system tracks people’s movements. If a government operative enters a person’s cellphone number, Aegis can show where the device has been over a given period of time: the last three days, the last week, the last month, or longer. The video displays a map of mainland China and zooms in to electronically follow a person in Shenzhen as they travel through the city, from an airport, through parks and gardens, to a conference center, to a hotel, and past the offices of a pharmaceutical company. The technology can also allow government users to run searches for a particular instant messenger name, email address, social media account, forum user, blog commenter, or other identifier, like a cellphone IMSI code or a computer MAC address, a unique series of numbers associated with each device. In many cases, it appears that the system can collect the full content of a communication, such as recorded audio of a phone call or the written body of a text message, not just the metadata, which shows the sender and the recipient of an email, or the phone numbers someone called and when. Whether the system can access the full content of a message likely depends on whether it has been protected with strong encryption. Zhu, the Semptian employee, wrote in emails that the company could provide governments an Aegis installation with the capacity to monitor the internet activity of 5 million people for a cost of between $1.5 million and $2.5 million. To eavesdrop on other communications, the cost would increase. “If we add phone calls, SMS, locations,” according to Zhu, “2 to 5 million USD will be added depending on the network.” In September 2015, Semptian joined the OpenPower Foundation, the U.S.-based nonprofit founded by tech giants Google and IBM. The foundation’s current president is IBM’s Michelle Rankin and its director is Google’s Chris Johnson. Registered in New Jersey as a “community improvement” organization, the foundation says its aim is to share advances in networking, server, data storage, and processing technology. According to its website, it wants to “enable today’s data centers to rethink their approach to technology,” as well as “drive innovation and offer more choice in the industry.” Semptian has benefited from the collaboration with American companies, gaining access to specialized knowledge and new technologies. The Chinese firm boasts on its website that it is “actively working with world-class companies such as IBM and Xilinx”; it claims that it is the only company in the Asia-Pacific region that can provide its customers with new data-processing devices that were developed with the help of these U.S. companies. Last year, the OpenPower Foundation stated on its website that it was “delighted” that Semptian was working with IBM, Xilinx and other American corporations. The foundation said it was also “working with some great universities and research institutions in China.” In December, OpenPower’s executives organized a summit in Beijing, at the five-star Sheraton Grand Hotel in the city’s Dongcheng District. Semptian representatives were invited to attend and demonstrated to their American counterparts new video analysis technology they have been developing for purposes including “public opinion monitoring,” one source told The Intercept.

“Sometimes it seems like there’s a ‘don’t ask, don’t tell,’ policy.”

It is unclear why the U.S. tech giants have chosen to work with Semptian; the decision may have been taken as part of a broader strategy to establish closer ties with China and gain greater access to the East Asian country’s lucrative marketplace. A spokesperson for the OpenPower Foundation declined to answer questions about the organization’s work with Semptian, saying only that “technology available through the Foundation is general purpose, commercially available worldwide, and does not require a U.S. export license.” Elsa Kania, an adjunct senior fellow at the Center for a New American Security, a policy think tank, said that in some cases, business partnerships and academic collaborations between U.S. and Chinese companies are important and valuable, “but when it is a company known to be so closely tied to censorship or surveillance, and is deeply complicit in abuses of human rights, then it is very concerning.” “I would hope that American companies have rigorous processes for ethical review before engaging,” Kania said. “But sometimes it seems like there’s a ‘don’t ask, don’t tell,’ policy — it’s profit over ethics.”
