How the NSA installs backdoors in US-made Internet routers

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. […]

A June 2010 report from the head of the NSA’s Access and Target Development department is shockingly explicit. The NSA routinely receives – or intercepts – routers, servers and other computer network devices being exported from the US before they are delivered to the international customers.

The agency then implants backdoor surveillance tools, repackages the devices with a factory seal and sends them on. The NSA thus gains access to entire networks and all their users. The document gleefully observes that some “SIGINT tradecraft … is very hands-on (literally!)”.

Eventually, the implanted device connects back to the NSA. The report continues: “In one recent case, after several months a beacon implanted through supply-chain interdiction called back to the NSA covert infrastructure. This call back provided us access to further exploit the device and survey the network.” […]
