Organizers said cyber threats are increasing rapidly in scale and sophistication, driven by malware, deepfake technology and automated attacks. In the third quarter of 2025 alone, Vietnam recorded more than 547,000 DDoS attacks, nearly 4,000 phishing domains, and over 500 million leaked data records.
The exercise features realistic scenarios designed to test incident response capacity, evaluate security procedures, uncover vulnerabilities, and improve inter-agency coordination.
According to Colonel Bui Thanh Truc, Deputy Director of the Ho Chi Minh City Public Security Department, the drill focuses on responding to real-world cyberattacks targeting the city’s public information portal, as well as evaluating the effectiveness of its multi-layered cybersecurity defenses.
