The thing about infrastructure is that everyone uses it. If it’s secure, it’s secure for everyone. And if it’s insecure, it’s insecure for everyone. This forces some hard policy choices.
When I was working with the Guardian on the Snowden documents, the one top-secret program the NSA desperately did not want us to expose was QUANTUM. This is the NSA’s program for what is called packet injection–basically, a technology that allows the agency to hack into computers.
Turns out, though, that the NSA was not alone in its use of this technology. The Chinese government uses packet injection to attack computers. The cyberweapons manufacturer Hacking Team sells packet injection technology to any government willing to pay for it. Criminals use it. And there are hacker tools that give the capability to individuals as well.
