The Hong Kong Cybersecurity Attack and Defence Drill 2026 was launched today (October 29) to test the defence mechanism and incident response capabilities of participating organisations over three consecutive days through simulated cyber threat scenarios.

The drill is spearheaded by the Digital Policy Office (DPO) in collaboration with the Office of the Commissioner of Critical Infrastructure (Computer-system Security) of the Security Bureau, the Cyber Security and Technology Crime Bureau of the Hong Kong Police Force, the Hong Kong Internet Registration Corporation Limited, Cyberport, the Hong Kong Cybersecurity Professional Association and the Hong Kong Institute of Information Technology. For the first time, this year's drill has invited private enterprises to join as defending teams to undergo practical combat training alongside government departments and public organisations, thereby enhancing Hong Kong's overall cybersecurity protection and resilience.

Addressing the opening ceremony, the Secretary for Innovation, Technology and Industry, Professor Sun Dong, said, "The Government adopts a holistic approach to development and security, bolstering our cybersecurity defence system by deepening cybersecurity protection and collaboration." He highlighted that the key to building a robust cybersecurity defensive line relies on translating defence into concrete actions and consistently testing and honing defensive capabilities of participating departments and organisations through practical combat.

The drill spans three days and two nights for a total of 60 hours, and will end on the evening of October 31 (Saturday).
