Target Trend
Summary

Show ▼
Taiwan’s critical infrastructure saw a sharp 2025 surge in China-linked intrusion attempts, reaching 960,620,609 and raising risk across essential services. The pressure was especially severe for energy, which saw a tenfold increase, and for hospitals and emergency rescue entities, which saw a 54% rise. The overall volume was also up 6% from 2024 and 112.5% from 2023, showing a sustained escalation rather than a one-off spike. The trend matters because it points to persistent, high-volume targeting of Taiwan’s critical sectors across the year.
