Vietnam ranks as the most cyber-attacked nation in Southeast Asia (SEA), with a cyber incident targeting its financial sector occurring on average every 57 seconds.
Vietnam recorded approximately 552,000 cyberattacks across 2025, with more than 41% directed at banking, securities, and insurance institutions. Compromised user accounts reached 8.5 million. On average, an attack hit the nation's financial industry every 57 seconds.
The figures were disclosed by Ms. Nguyen Thi Son Binh, Deputy Director of the Digital Enterprise Solutions Center at Viettel Telecom, during a seminar marking the 30-year development of Vietnam's securities market.
Ms. Binh noted that Vietnam suffers the highest cyberattack volume in Southeast Asia, recording roughly 2.5 times more incidents than Indonesia and Malaysia.
The statistics underscore the urgent imperative to enhance cybersecurity risk management capacity, particularly as the securities market accelerates digital transformation initiatives.
According to Ms. Binh, multiple vulnerabilities across the securities sector—ranging from information security and transaction authentication to internal corporate operations—can be anticipated and proactively mitigated by deploying properly engineered control frameworks.
A primary challenge remains the uneven pace of digitalization across financial institutions. While many workflows have migrated online, certain operational phases still rely on physical paper records and manual processing. This operational gap hinders complete data-flow oversight while heightening the risk of operational errors and confidential data leaks.
