A recent simulation suggests the U.S. is underprepared for Chinese cyberattacks on Taiwan, while separate reports track increased Chinese maritime activity near the island.

Key facts
- •The FDD war game findings were briefed to Taiwanese President Lai Ching-te and his national security team.
- •Retired Navy rear admiral Mark Montgomery stated that the U.S. Department of Defense lacks a systematic process for managing cyber-focused tabletop exercises.
- •The simulation scenario was informed by the Chinese hacking campaign known as Salt Typhoon.
- •The August maritime sighting marked the first known instance of a Chinese militia boat operating off Taiwan's east coast.
- •Taiwanese officials believe the militia fleet is being used to conduct substantive harassment in coordination with coast guard drills.
A war game organized by the Foundation for Defense of Democracies (FDD) has revealed potential vulnerabilities in U.S. preparedness for a Chinese campaign of cyberattacks and economic pressure against Taiwan. The exercise, held in Taiwan in late September, demonstrated how Beijing could disrupt communications and infrastructure to extract political concessions without launching a full-scale invasion.
Cyber and Infrastructure Vulnerabilities
The FDD simulation explored a multi-phase escalation, beginning with localized cellular disruptions and information manipulation before moving to the destruction of undersea cables and electrical substations. Organizers noted that while the U.S. military frequently rehearses for direct conflict, there is a lack of systematic planning for cyber operations. Participants warned that current gaps between military and civilian agencies could delay assistance to Taiwan during a crisis, particularly if backup systems are targeted over several weeks.
Increased Maritime Activity
Separately, Taiwanese officials and surveillance reports have identified an increase in Chinese maritime activity off the island's east coast. In mid-August, a Chinese maritime militia vessel, the Minfudingyu 07902, was observed operating alongside a China Coast Guard cutter and a research vessel. Taiwan's Ministry of National Defense stated that China is utilizing these civilian and paramilitary assets to practice for potential blockades and to create an illusion of jurisdiction in the region.
