China has significantly intensified its alleged cyberattacks against Taiwan over the past year, escalating tensions in one of Asia’s most sensitive geopolitical flashpoints. According to official data from Taipei, an average of 2.63 million cyberattacks per day were recorded in 2025, primarily targeting critical infrastructure such as hospitals, banks, and emergency services. Taiwan’s National Security Bureau reported that the total number of attacks increased by six percent compared to 2024, reinforcing a trend that has raised growing concern on the island.
Since authorities first began publishing detailed figures in 2023, the volume of daily cyber incidents has surged by more than 113 percent, pointing to a sustained and accelerating escalation. The report indicates that many of the attacks were not random. Several cyber offensives were synchronized with Chinese military drills near Taiwan, a pattern that Taiwanese officials describe as part of a strategy of “hybrid threats” designed to pressure and destabilize the island without triggering a direct military confrontation. Taiwan has long accused Beijing of conducting hybrid warfare, combining military intimidation, disinformation campaigns, and cyber operations.
In 2025, the impact was particularly severe in sensitive sectors such as energy, emergency response systems, and hospitals, raising alarms about public safety and national resilience. According to the security assessment, these attack patterns suggest a deliberate attempt to weaken Taiwan’s critical infrastructure and disrupt essential state and social functions. Analysts believe the objective is to undermine public confidence while testing the island’s ability to withstand prolonged pressure. Another major target was Taiwan’s science and technology parks, which host some of the world’s most advanced semiconductor facilities.
These complexes include companies such as TSMC, a cornerstone of the global chip supply chain and a strategic asset in international technology competition. Taiwanese authorities say attackers employed sophisticated techniques to steal advanced technologies and sensitive data, reinforcing suspicions that Beijing aims to accelerate its technological self-sufficiency and reduce dependence on foreign suppliers, particularly amid strategic rivalry with the United States. The report adds that China’s so-called “cyber army” has adjusted its activity in parallel with military pressure.
In at least 23 of the 40 Chinese military patrols recorded near Taiwan, spikes in cyberattacks were detected simultaneously, strengthening the case for coordinated strategic planning. Beijing, however, has categorically rejected the accusations. China’s Taiwan Affairs Office did not respond to requests for comment, and the Chinese government regularly denies involvement in hacking campaigns targeting the island. China considers Taiwan part of its territory and has never ruled out the use of force to achieve reunification.
Taipei firmly rejects Beijing’s sovereignty claims, maintaining that only the Taiwanese people have the right to determine their political future. The dispute dates back to the Chinese civil war, when the nationalist government retreated to Taiwan after its defeat by communist forces. Since 1949, the island has been governed independently, while the People’s Republic of China was established on the mainland.
Within this historical and geopolitical context, the surge in cyberattacks reinforces the perception that the conflict between China and Taiwan is no longer confined to military maneuvers or diplomatic pressure. Increasingly, it is being fought in cyberspace—an invisible but decisive battleground of 21st-century warfare.
