I somehow missed this Foreign Policy profile of David Vincenzetti, published exactly a year ago.

You won't learn anything if you already went through the abundant documentation on Hacking Team, but still worth a read.

Also, this NYT longform - mostly focusing on HT - was good. https://www.nytimes.com/2017/01/04/magazine/cyberwar-for-sale.html
