在「To Avoid NSA Interception, Cisco Will Ship To Decoy Addresses」這篇看到的報導，出自「Cisco posts kit to empty houses to dodge NSA chop shops」這篇。
去年 Snowden 揭露的資料顯示 NSA 會攔截 Cisco 的硬體，並且在上面安裝後門再打包寄出：「Greenwald alleges NSA tampers with routers to plant backdoors」：
"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.
不過 Cisco 的反應好慢，去年五月就有的消息，現在才提出改善方案。
改善的方法是寄送到集散地，再請人去拿。讓 NSA 之類的單位想要攔截的成本提高。
