Description: This document is an article from the internal NSA newsletter SIDtoday. The article discusses the success of a collaboration between offensive and defensive branches of the NSA. For example, the revelation of a Chinese cyber attack on the Department of Defense was used to gain visibility into Chinese SIGINT intelligence, notably including files that the Chinese intelligence team had accessed from the United Nations. The article refers to this kind of operation as "Fourth Party collection."
