Behind the Ransomware Attacks

According to statistics from Bkav Group in 2024 and early 2025, 155,640 computers were attacked by ransomware.

In Vietnam, the damage caused by this virus has amounted to tens of thousands of billions of VND, including: money paid to hackers to ransom data, direct revenue loss due to system downtime, damage due to lost customers, brand damage, etc.

For example, on the first day of a data encryption attack, one business lost more than 100 billion VND. Another business's estimated damage after being attacked by ransomware was up to 800 billion VND.

Internationally, cyber attacks will cause damage of about 9,500 billion USD by 2024 (Cybersecurity Ventures).

According to Bkav experts, what is being seen or calculated is just the tip of the iceberg. In recent years, requests for help due to ransomware attacks have been sent to Bkav at a high density.

Research shows that virus activity is increasingly dangerous and sophisticated with clear, methodical attack strategies. Data encryption viruses target businesses, extortion targets with huge ransoms.

Advanced Persistent Threat (APT) viruses spread silently and lie dormant in agencies and organizations to steal information.

"Every day, millions of new virus samples appear and the damage caused by malware is terrible. But in Vietnam, up to 60% of businesses are not equipped with strong enough security solutions," said Mr. Nguyen Dinh Thuy, Head of Malware Research Department of Bkav.

In fact, many businesses only rely on the operating system's built-in anti-virus feature, which is only basic and not capable of protecting users from today's sophisticated viruses.

The built-in antivirus feature on the operating system cannot completely solve virus problems because it only provides the most basic features. Therefore, users will not be fully protected from APT malware or ransomware, which are designed to penetrate deep into the system to lie dormant, steal data or extort money.

Bkav experts said that APT spy viruses and ransomware are hiding in many systems in Vietnam, they are spreading silently and will cause harm and attack at the right time in the near future.

Agencies, organizations and businesses especially need to raise awareness of cyber security and immediately apply measures to prevent computer viruses in a professional manner.
