Cache Me If You Can

In this episode of Cache Me if You Can, we explore one of the most consequential cyber alliances in the Indo-Pacific: cooperation between the United States and the Republic of Korea. As cyber threats grow more sophisticated, from state-sponsored operations and ransomware to cryptocurrency theft and attacks on critical infrastructure, both countries are grappling with how to strengthen resilience and move beyond coordination toward deeper operational collaboration. Our guests, Dr. Jim Lewis of CSIS and researchers Sunha Bae and Joohui Park of South Korea's National Security Research Institute (NSR), draw on their expertise in cyber strategy, international law, and critical infrastructure security to examine the evolving threat landscape and the future of allied cyber cooperation. Together, they unpack how North Korea's cyber activities have evolved, the growing challenge of cryptocurrency-enabled illicit finance, and the role cyber operations play in Pyongyang's broader national strategy. We discuss South Korea's emerging approach to active cyber defense, lessons from U.S. concepts such as defend forward and persistent engagement, and the legal and policy considerations that accompany more proactive cyber operations. The conversation also explores how the U.S.–ROK alliance can operationalize cyber cooperation, coordinate responses to shared threats, and work with regional partners to build a more resilient and secure digital environment across the Indo-Pacific.

In this episode of Cache Me if You Can, we dive beneath the surface to explore the fragile networks that keep the world connected. Our guest, Dr. Anna-Maria Osula, Cyber and Economic Counselor at the Estonian Embassy in Washington D.C., unpacks the geopolitical and technical stakes of securing subsea cables. We discuss Europe’s emerging Cable Security Action Plan, NATO’s new Baltic Sentry surveillance mission, and how hybrid threats, from anchor drags to covert sabotage, are reshaping the way allies think about resilience. Together, we examine what happens when the world’s data highways become battlefields, and what Europe’s experience can teach the rest of the world about protecting the foundations of the digital age.

In this episode of Cache Me if You Can, host Matt Pearl sits down with Anne Neuberger, former Deputy National Security Advisor for Cyber and Emerging Technologies, to unpack how the United States can build a resilient cyber strategy in the face of growing Chinese aggression. Drawing on her recent Foreign Affairs publication, Neuberger explains why China is winning the cyberwar, how AI-enabled “digital twins” could transform U.S. defense, and why resilience, not offense, must underpin deterrence. The conversation explores the convergence of intelligence, cybersecurity, and emerging technologies, the role of the private sector in defending critical infrastructure, and what it will take to secure America’s digital future.

In this first episode of Cache Me if You Can, host Matt Pearl sits down with Scott Kennedy, Senior Adviser and Trustee Chair in Chinese Business and Economics at CSIS and a leading expert on China’s innovation system. They explore how Beijing’s massive investments in sectors like semiconductors, AI, and electric vehicles are reshaping global competition, what lessons the U.S. can draw from allies, and the pivotal choices Washington faces to stay ahead in the tech race.
