writes "According to Glenn Greenwald, reporting at The Guardian: '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!)".'"
