Nicole Perlroth’s This is How They Tell Me the World Ends is a deep dive into the history of the global cyberweapons market. It covers the origins of bug bounty programs, some history of offensive operations at the NSA, a narrative of well-known cyberattacks, and discussion of the risk the United States faces from digital attack. It is equal parts exciting and terrifying and overall a worthy read for anyone interested in cybersecurity.
