Jack Goldsmith spoke with New York Times cybersecurity reporter Nicole Perlroth about her new book, "This is How They Tell Me the World Ends: The Cyberweapons Arms Race." They discussed the dark world of markets for zero-day vulnerabilities that are so vital in offensive cyber operations, the history of the markets, how they work, who the players are and why the United States doesn't control as much as it used to. They also discussed broader issues of U.S. cybersecurity policy, including the recent SolarWinds hack. See acast.com/privacy for privacy and opt-out information.
