I think the public still isn't aware of the frequency with which the cyber-attacks, as they're being called in the press, are being used by governments around the world, not just the US.

My government revoked my passport intentionally to leave me exiled. If they really wanted to capture me, they would've allowed me to travel to Latin America, because the CIA can operate with impunity down there. They did not want that; they chose to keep me in Russia.

A zero-day exploit is a method of hacking a system. It's sort of a vulnerability that has an exploit written for it, sort of a key and a lock that go together to a given software package. It could be an internet web server. It could be Microsoft Office. It could be Adobe Reader or it could be Facebook.

If we simply follow the rules that a state imposes upon us when that state is acting contrary to the public interest, we're not actually improving anything. We're not changing anything.

The United States need to be focusing more on creating a more secure, more reliable, more robust, and more trusted internet, not one that's weaker, not one that relies on this systemic model of exploiting every vulnerability, every threat out there.

People have to be free to investigate computer security. People have to be free to look for the vulnerabilities and create proof of concept code to show that they are true vulnerabilities in order for us to secure our systems.

The issue I brought forward most clearly was that of mass surveillance, not of surveillance in general.
