Glenn Greenwald: how the NSA tampers with US-made internet routers

The NSA has been covertly implanting interception tools in US servers heading overseas – even though the US government has warned against using Chinese technology for the same reasons, says Glenn Greenwald, in an extract from his new book about the Snowden affair, No Place to Hide

For years, the US government loudly warned the world that Chinese routers and other internet devices pose a "threat" because they are built with backdoor surveillance functionality that gives the Chinese government the ability to spy on anyone using them. Yet what the NSA's documents show is that Americans have been engaged in precisely the activity that the US accused the Chinese of doing.

The drumbeat of American accusations against Chinese internet device manufacturers was unrelenting. In 2012, for example, a report from the House Intelligence Committee, headed by Mike Rogers, claimed that Huawei and ZTE, the top two Chinese telecommunications equipment companies, "may be violating United States laws" and have "not followed United States legal obligations or international standards of business behaviour". The committee recommended that "the United States should view with suspicion the continued penetration of the US telecommunications market by Chinese telecommunications companies".
