This chapter presents a hypothetical cyber war exercise called 'Exercise South China Sea' involving escalating tensions between the U.S. and China over contested maritime territories. It explores the strategic dilemmas faced by U.S. Cyber Command in balancing the use and preservation of cyber attack capabilities, the challenges of penetrating China's cyber defenses, and the potential for reciprocal disruptive cyber operations targeting critical infrastructure. The scenario illustrates how cyber warfare could be integrated into broader military and political strategies, emphasizing deniability, escalation control, and the risks of cyber conflict spillover.

This chapter introduces the emergence and escalation of cyberwarfare through the activities of the Kremlin-backed hacker group Sandworm, highlighting their devastating attacks on Ukraine's critical infrastructure culminating in the global NotPetya malware outbreak in 2017. It contextualizes these events within a broader geopolitical cyber arms race, emphasizing the unprecedented scale and potential future consequences of state-sponsored digital sabotage. The prologue personalizes the impact by recounting a midnight blackout in Kiev, symbolizing the tangible human and societal effects of cyberattacks.

This chapter recounts two significant flashbacks illustrating the evolution and potential of cyberwarfare. The first, the Aurora experiment in 2007, demonstrates how a small amount of malicious code can physically destroy a large diesel generator by manipulating protective relays in the power grid. The second flashback traces the origins of state-sponsored hacking back to the 1980s with the Moonlight Maze incident, highlighting the early sophistication and persistence of cyber espionage efforts.

This chapter details the emergence of the Sandworm hacking group and its unprecedented cyberattack on Ukraine's power grid in late 2015, marking a new era of cyberwarfare that crossed from digital intrusion to physical sabotage. Despite clear evidence of the attack's severity and implications for U.S. infrastructure, government agencies initially downplayed the threat and withheld public warnings, missing a critical opportunity to establish international norms and deterrence against cyberattacks on civilian infrastructure. The chapter contrasts the muted response to Sandworm with the decisive public condemnation and retaliation following North Korea's 2014 Sony hack, highlighting political and bureaucratic challenges in addressing state-sponsored cyberwarfare.

Chapter 15 'Warnings' compiles various authoritative statements and incidents illustrating the escalating severity and visibility of cyberattacks from state actors like North Korea, China, Russia, and Iran. It highlights the destructive impact of these intrusions on critical infrastructure and corporate targets, as well as the challenges faced by U.S. authorities in attribution and response. The chapter underscores the growing recognition among security experts and government officials of the persistent and evolving cyber threats to national security.

Chapter 27, titled 'The Cost,' examines the extensive financial and operational impacts of the NotPetya cyberattack on major global corporations such as Maersk, Merck, and Reckitt Benckiser. It highlights the challenges faced in recovery efforts, including prolonged system reinstallations and disruptions to critical services, while also referencing broader concerns about drug shortages and emergency care delays linked to cyber incidents. The chapter draws on various reports and expert commentary to illustrate the tangible consequences of cyberwarfare on industry and public health.

Chapter 33, titled 'The Penalty,' details the international attribution and condemnation of the 2017 NotPetya cyberattack, widely attributed to the Russian military. It covers official statements from multiple governments and cybersecurity agencies condemning the attack, Russia's denial and rejection of the accusations, and subsequent U.S. sanctions targeting Russian cyber actors. The chapter also highlights concerns about Russian cyber intrusions into critical infrastructure, including the U.S. power grid, as reported by security firms and government officials.
