In this episode of Code and Country, Ian L. Paterson speaks with Craig Newmark, Craigslist founder and philanthropist, about his $200 million commitment to U.S. cybersecurity. Craig outlines his vision for "cyber civil defense"—a World War II-style mobilization where every American helps protect against nation-state threats like China's Salt Typhoon and Volt Typhoon campaigns targeting critical infrastructure. The discussion covers urgent vulnerabilities in small water systems, the Cyber Resilience Corps, and initiatives like PauseTakeNine.org. This episode offers security leaders and policymakers a roadmap for collective defense against today's cyber threats.
