2025 records a worrying paradox in the cybersecurity landscape: although the total number of attacks tends to decrease slightly compared to the previous period, the extent of damage has skyrocketed.
The Vietnam cyber attack report 2025 shows that high-tech criminals have professionalized, turning data into the No. 1 hunting target.
Paradox 2025: Decreasing quantity, sharply increasing damage
According to statistics from the NCA (Department of Cybersecurity and High-Tech Crime Prevention), in the past year, there were approximately 552,000 Vietnam cyber attacks 2025, directly affecting 523 critical units and organizations.
The biggest difference in 2025 is the shift from "widespread" attacks to targeted attacks (APT). Instead of superficial sabotage, hackers focus directly on system "vital points" to maximize ransom payments and the value of stolen data.
Data – The new "Gold mine" of cybercriminals
No longer just mere defacement or access disruption, 2025 witnesses the rise of data-centric campaigns. Data is not only an asset but has become a "weapon" for hackers to threaten businesses.
Data encryption attacks (Ransomware) remain a terrifying obsession. However, instead of just encrypting, hackers now favor a "double extortion" tactic:
System encryption: Paralyzing all business operations.
Data leak threats: If the ransom is not paid, sensitive customer information and business secrets will be released on dark forums (Darkweb), causing serious damage to reputation and legal standing.
"Dwell" Tactic – Hackers are more patient than you think
Analyzing typical Vietnam cyber attacks 2025, especially at more than 52 businesses that suffered heavy losses recently, experts found that hackers do not attack immediately. They use a "wait-and-see, dwell" tactic.
On average, an attacker can hide in the system for 3 to 6 months. During this time, they silently:
Monitor information flows and important financial transactions.
Search for and disable backups (backup) before taking action.
Study the data structure to identify the most valuable information.
This makes defense extremely difficult if businesses only rely on traditional security solutions.
Defense vulnerabilities against Vietnam cyber attacks 2025: Shortage of personnel and standards
Although information security awareness has increased, the current state of defense in Vietnam still has many alarming gaps:
Personnel shortage: 47.72% of businesses do not have a specialized cybersecurity team.
Lack of standardization: 27.80% of units have not applied any internal security standards.
Weak infrastructure: Nearly 10% of businesses do not have a firewall and 50% lack centralized anti-malware software.
Which business sectors are in the "crosshairs"?
In 2025, not only large corporations but also small and medium-sized enterprises (SMEs) holding high-quality user data have become lucrative targets. The most attacked sectors include:
Finance - Banking.
Healthcare and Insurance.
E-commerce.
Supply chain and Logistics.
What do businesses need to do to protect themselves in 2026?
Entering 2026, attacks are expected to be automated by AI, making the risks even higher than during the Vietnam cyber attacks 2025 period. Compliance with the Law on Cybersecurity and Decree 13 (Personal Data Protection Law) becomes a vital requirement at this time.
To adapt, IPSIP Vietnam recommends that businesses immediately implement 4 defense pillars:
24/7 Proactive Monitoring: Deploy SOC 24/7 services to early detect "dwell" signs from hackers instead of waiting until the system crashes.
Multi-layered Backup Strategy: Apply the 3-2-1 principle (3 copies, 2 types of storage media, 1 offline copy) to ensure data recovery capabilities.
Human Awareness Training: Over 80% of attacks start from human error (phishing, weak passwords).
In-depth Data Security Investment: Shift from perimeter defense to directly protecting critical data layers.
The cybersecurity war of 2025 has proven that hackers are becoming increasingly professional and patient. Businesses need a new security mindset: more proactive, more thorough, and more sustainable.
