China Ramps Up Cyberattacks Targeting Taiwan
▼ Summary
– Chinese cyber actors intensified efforts to target Taiwan’s critical infrastructure in 2025, focusing on the energy sector, emergency rescue entities, and hospitals.
– Taiwan’s National Security Bureau reported a record 960+ million cyber intrusion attempts from China in 2025, averaging 2.63 million daily attacks per critical organization.
– The total number of intrusion attempts in 2025 marked a 6% increase from 2024 and a 112.5% increase compared to 2023.
– The energy sector experienced the most dramatic spike, suffering a tenfold increase in cyber intrusion attempts compared to 2024.
– While attacks on energy and emergency/hospital sectors surged, attempts on water resources and finance sectors decreased by 50% and 48.2% respectively.
A significant escalation in cyber intrusion attempts targeting Taiwan’s critical infrastructure has been documented, with a pronounced focus on the energy sector, emergency services, and hospitals. According to a recent report from Taiwan’s National Security Bureau, these activities, attributed to threat actors based in China, reached unprecedented levels in 2025. The data reveals a staggering total of over 960 million cyber intrusion attempts aimed at the island’s vital systems throughout the year. This figure translates to an average of approximately 2.63 million daily attacks on a single critical organization, marking a 6% rise from 2024 and a dramatic 112.5% surge compared to 2023 levels.
Taiwan classifies nine sectors as critical infrastructure, encompassing communications, energy, finance, food supply, government, industrial parks, transportation, water resources, and notably, emergency rescue and hospitals. The most alarming increase was observed in the energy sector, which experienced a tenfold jump in intrusion attempts compared to the previous year. Similarly, entities responsible for emergency response and healthcare faced a 54% rise in cyber threats. This strategic targeting suggests an effort to compromise systems essential for societal stability and public safety during potential crises.
In contrast to these surges, two critical sectors saw a notable decline in attack volumes. Attempts targeting water resources and financial institutions decreased by 50% and 48.2%, respectively. This shift in focus highlights the evolving priorities of the threat actors, who appear to be concentrating their resources on infrastructure that could cause maximum disruption. The concentration on energy and emergency services points to a campaign designed to test resilience and potentially weaken key operational capabilities.
The sustained and growing scale of these cyber operations represents a continuous challenge for Taiwan’s cybersecurity defenses. Protecting essential services from such persistent and sophisticated threats requires constant vigilance, advanced threat detection, and robust incident response protocols. The data underscores the importance of international awareness regarding the targeting of civilian critical infrastructure in geopolitical tensions, as these actions have direct implications for economic security and public welfare.
