Web threats are cyberattacks that exploit vulnerabilities in browsers, plugins and online platforms to spread malware and other malicious content.
Common techniques include drive-by downloads, which infect users automatically when visiting compromised websites, and social engineering schemes that trick users into downloading harmful files disguised as legitimate applications.
Across south-east Asia, exposure varied widely. The Philippines recorded the highest rate at 32.9 per cent, ranking sixth globally, followed by Malaysia at 26.7 per cent.
Indonesia, Singapore and Thailand reported lower exposure levels than Vietnam, at 22.4 per cent, 21.2 per cent and 20.3 per cent respectively.
Despite Vietnam’s comparatively lower rate, nearly one in four users was affected, underscoring the continued need for stronger web security practices.
Kaspersky said it detected 23.84 million web-borne threats targeting users in Vietnam in 2025, equivalent to more than 65,000 attacks per day on average, the highest total among six regional markets analysed.
However, the number of threats has been on a downward trend in recent years, indicating gradual improvements in cybersecurity resilience.
Simon Tung, Kaspersky’s general manager for south-east Asia, said Vietnam has made measurable progress in strengthening its cybersecurity ecosystem through national strategies and public-private cooperation.
He warned that while overall exposure rates are improving, threats are becoming more targeted and sophisticated, particularly through browser-based exploits and advanced phishing campaigns.
For individuals, Kaspersky recommends downloading apps only from trusted sources, keeping software updated, avoiding suspicious links and using strong passwords with two-factor authentication.
For businesses, it advises implementing multi-factor authentication, updating systems regularly, monitoring security incidents in real time and training employees to reduce the risk of social engineering attacks.
