Overview of Cyberattacks
In 2025, Chinese cyberattacks on Taiwan's critical infrastructure surged to an average of 2.63 million incidents per day, marking a 6% increase from 2024 and more than double the rate observed in 2023, according to Taiwan's National Security Bureau (NSB). These attacks targeted essential sectors, including hospitals, banks, energy networks, and telecommunications, and were often synchronized with Chinese military drills, reflecting a strategy of "hybrid warfare" aimed at destabilizing Taiwan.
Tactics and Techniques Employed
The NSB's report identified four primary tactics used by Chinese cyber actors: exploitation of hardware and software vulnerabilities, distributed denial-of-service (DDoS) attacks, social engineering, and supply chain attacks. Notably, over half of the intrusion attempts exploited vulnerabilities in information and communications technology (ICT) equipment. DDoS attacks, which accounted for 21% of incidents, aimed to overwhelm Taiwan's networks, while supply chain attacks targeted the networks of suppliers to infiltrate critical systems.
Key Targets and Impact
Taiwan's semiconductor industry, particularly science parks housing firms like Taiwan Semiconductor Manufacturing Company (TSMC), was a significant focus for attackers. The report suggested that these efforts were part of China's broader strategy to enhance its technological self-reliance amid escalating U.S.-China tech competition. The NSB noted that the most significant increases in cyberattacks were seen in the energy sector, which experienced a tenfold rise compared to the previous year.
Official Statements & Responses
Taiwan's government has condemned these cyberattacks as part of China's ongoing campaign to assert sovereignty claims over the island. The NSB emphasized the need for robust cybersecurity measures, stating, "We strive to obtain timely intelligence on attack patterns of China’s cyberarmy by cooperating closely with international friends and allies." The agency has engaged in dialogues with over 30 countries to enhance its cyber defense capabilities.
Criticism & Opposition
Critics argue that the scale and coordination of these cyberattacks highlight the vulnerabilities in Taiwan's cybersecurity infrastructure. Some experts warn that the ongoing cyber threats could escalate into broader conflicts, as they test Taiwan's resilience without direct military engagement.
What's Next
In response to the increasing cyber threats, Taiwan is expected to accelerate investments in cybersecurity and deepen cooperation with international partners. The NSB has indicated plans to enhance its resilience and response preparedness against potential future attacks, particularly during politically sensitive events.
