Taiwan’s National Security Agency states that the number of Chinese cyberattacks against the country’s critical infrastructure increased by 6% in 2025, averaging 2.6 million attacks per day, Reuters reports.
The attacks mainly targeted the energy sector, hospitals, banks and emergency services, and many of them were reportedly coordinated with Chinese military exercises and political events. For example, when the President and Vice President of Taiwan were giving speeches or attending international meetings.
The attackers reportedly used methods such as denial-of-service (DDoS) attacks and man-in-the-middle intrusions to steal data and disrupt operations. This includes the semiconductor industry and companies like TSMC.
