police-guide-banks(1).jpg — City police officers and soldiers guide employees of the Military Commercial Joint Stock Bank to update information about related fraud tricks on cyberspace.

Sophisticated and diverse tricks

According to statistics, in the first 9 months of 2025, the Department of Cyber Security and High-Tech Crime Prevention received and handled 48 denunciations and reports of crimes, of which 17 cases were initiated for investigation, all related to banking transactions. According to Lieutenant Colonel Trinh Hong Thai, Deputy Head of the Department of Cyber Security and High-Tech Crime Prevention, the methods and tricks of criminals are increasingly sophisticated, such as impersonating law enforcement agencies to trick people into providing account information; creating fake websites, applications, and bank brand messages; malware attacks, blackmail; using AI, Deepfake to bypass biometric authentication; spreading fake news, rumors of "bank bankruptcy", "mass withdrawals" to cause public confusion...

Mr. Dinh Van Minh, Deputy Director of MB Bank Hai Phong Branch, informed that from customer feedback, most people fall into the trap of having difficulty or not being able to identify the scams, following the scenarios that are being lured, leading to personal information being leaked or making customers' devices unsafe when infected with malicious code. From there, bad guys take control, proactively provide card information, make money transfers, and make payments according to the scenarios that are being lured... More dangerously, the forms of scams and attacks change frequently and are diverse, making it difficult not only for customers but also for banks to proactively control.

Similarly, the VietinBank system also recorded many cases of customers being tricked into transferring money, although warnings were given but it was still difficult to detect due to professional and sophisticated tricks. Meanwhile, the situation of personal information being leaked and bank account buying and selling is common on social networks and the "underground" market. Many subjects take advantage of people's lack of knowledge to buy, rent accounts, and use them for illegal purposes, causing damage to customers and potentially causing security and order problems.

The above reality shows that, in the context of strong digital transformation, high-tech crime is becoming a non-traditional security challenge, directly affecting the financial and banking systems, the economy and people's lives.

The city police force maintains a continuous alarm system with the banks.

Strengthening prevention coordination

Through review, there are currently about 40 banks with branches operating in Hai Phong city, of which the proportion of joint stock commercial banks accounts for more than 80%, the rest are state banks, 100% foreign-invested banks. With the strong development of the 4.0 revolution, the operations of banks in Vietnam in general and Hai Phong in particular based on digital and electronic platforms have made a strong breakthrough with the number of accounts opened by individuals and organizations, the number of online transactions increasing dramatically, especially after the COVID-19 pandemic. However, this remarkable growth also has the potential for high-tech crimes targeting a huge number of customers and banks, especially commercial banks which account for a large number in the current banking system.

Strengthening its defense system, Military Commercial Joint Stock Bank MBBank proactively and effectively deployed the "AI application solution set to protect customer transactions". The deployed solution set operates in many layers of protection with an early detection model to prevent and combat fraud risks. As a result, over the past time, the bank's AI system has helped protect hundreds of billions of VND each year from fraud attacks. In addition, AI also has the ability to automatically update and adapt to new fraud trends through big data analysis, which traditional analysis methods cannot do. According to initial statistics, the total amount of money protected for customers by the above solution set is up to tens of billions/month, reducing the number of fraud cases by more than 85% compared to the time before deployment.

According to Ms. Ngo Thi Kim Phuong, Deputy Director of Kien Long Bank Hai Phong Branch, the bank regularly updates urgent security warnings on official channels such as Website, Mobile Banking Application, verified Fanpage, focusing on new tricks and methods provided by the Department of Cyber Security and High-Tech Crime Prevention to help customers and bank employees quickly identify and prevent.

At the conference on strengthening crime prevention and control in the banking sector organized by the City Police in mid-October 2025, Lieutenant Colonel Vu Xuan Bao, Head of the Department of Cyber Security and High-Tech Crime Prevention and Control, emphasized: "Ensuring cyber security and preventing high-tech crimes in the banking sector is not only a professional task, but also a common responsibility in protecting national economic security". He affirmed that the Department of Cyber Security and High-Tech Crime Prevention and Control will continue to accompany credit institutions, strengthen coordination mechanisms, share information, improve response capacity, and contribute to maintaining financial security, social order and people's trust in the banking system.
