When the United States cannibalize dollars from the defensive business of the NSA, securing our communications, protecting our systems, patching zero-day vulnerabilities, and instead we're giving those dollars to be used for creating new vulnerabilities in our systems so that they can surveil us and other people abroad who use the same systems.
Edward SnowdenA 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.
