Vietnam has emerged as a cornerstone of the global digital economy, but this rapid digitization has come with a significant surge in sophisticated cyber threats. As the country transitions into a more mature technological landscape, the methods used to protect its most critical asset, the workforce, must also evolve. We are witnessing a pivotal move away from traditional, checkbox in-person training toward modern, automated and AI-driven digital resilience.

For years, ransomware was treated mostly as a malware problem. A user clicked something bad, files were encrypted, a ransom note appeared and everyone had a very bad week. That version still exists, of course, because cybercriminals love recycling old hits. But ransomware has changed significantly over the last year.

Researchers at Microsoft warn that phishing emails are still the top initial access vector, with more than 2 billion phishing threats detected each month during the second quarter of 2026.

Like many, the travel and tourism industry has undergone a radical digital transformation over the last few years. From AI-curated itineraries and biometric check-ins to interconnected booking engines and smart room tech, the modern “Digital Guest Journey” is more seamless than ever before. However, this rapid innovation has come at a steep price.

You cannot protect what you do not know exists. That statement has been true throughout the history of cybersecurity, but it has become even more important as organizations adopt new technologies and employees gain access to powerful AI tools. While many organizations focus on defending against external threats, they often overlook a growing problem much closer to home: devices, applications, and services operating within their environment that nobody knows about.

Threat actors are increasingly abusing trusted workflows to carry out attacks, according to a new report from Gen Digital. “ are not only sending malicious links or dropping malware,” the report says. “They are abusing context, sessions, workflows, brands, update systems, advertising platforms and delegated authority.

Attackers are using compromised hotel Wi-Fi routers to redirect users to Microsoft 365 phishing sites, according to researchers at ReliaQuest. The attacks were observed in multiple U.S. cities, as well as across India and Saudi Arabia. These types of DNS poisoning attacks can send users to phishing sites with very little evidence that something suspicious has taken place.

As a CISO advisor, I am observing a familiar pattern gaining a new, critical dimension. What we historically identified as "Shadow IT", the use of unapproved SaaS and tools, is rapidly evolving into "Shadow AI." Employees are increasingly leveraging AI bots for drafting, analysis, code generation and strategic decision-making.

An initial access broker for ransomware gangs is targeting organizations with voice phishing (vishing) attacks through Microsoft Teams, according to researchers at Zscaler’s ThreatLabz. “From January through June 2026, ThreatLabz examined a cluster of related campaigns that used Microsoft Teams vishing and Quick Assist for initial access, followed by PowerShell-based staging,” the researchers write.

AI agents offer unprecedented capabilities, speed, automation, deep context, and hyper-personalization, that will transform how we work. However, these same capabilities make AI agents significantly more dangerous than traditional software when hijacked by cybercriminals. You simply cannot rely on yesterday's risk management playbooks to handle today's AI-driven threats.
