One of the themes of our analysis has been how intelligence is increasingly being sub-contracted to private companies rather than carried out by government agencies as it was in the “old days”. There is a superb analysis of this phenomenon entitled “A New Age of Warfare” on the New York Times website (http://www.nytimes.com/2019/03/21/us/politics/government-hackers-nso-darkmatter.html). It is long and detailed, but well worth a read if you interested in this subject.
