With online fraud becoming increasingly sophisticated, AI is becoming a powerful weapon against cybercrime. Experts propose an AI-integrated solution to identify fraudulent calls and prevent personal data leaks.

Speaking to Tuoi Tre, Mr. Trinh Nguyen Thien Phuoc, technology director of Gianty Vietnam Company, said that cross-border online fraud is becoming increasingly sophisticated, especially in the Golden Triangle area. AI and Big Data technologies will play an important role in early detection and prevention of fraudulent behavior.
"AI can analyze real-time transaction data, recognize voices in fake calls, and monitor social media content to detect fraudulent websites. This technology not only helps warn users but can also automatically block suspicious transactions, lock accounts, or stop fraudulent campaigns before they spread," Phuoc analyzed.
In addition, AI also helps optimize the fraud reporting portal by screening, classifying, and prioritizing serious cases. AI chatbots can automatically guide victims, reducing the burden on authorities, while AI systems can link data from multiple fraud cases to support rapid investigations.
Mr. Phuoc proposed: "Technology companies, banks and network operators need to coordinate closely to share data, deploy monitoring and early warning technology." At the same time, he recommended establishing specialized committees or associations, and continuously training agencies and departments like a "cyberspace fire prevention and fighting" unit.
In addition, Mr. Phuoc also proposed the Bounty Hunter model to encourage security experts to participate in hunting cyber criminals with a transparent reward mechanism, contributing to improving the effectiveness of preventing online fraud.
According to Mr. Hoang Xuan Huong, technology director of VNetwork cybersecurity company, with current technological potential, Vietnamese network operators can completely record subscribers connecting from broadcasting stations in areas where cybercriminals are operating. From there, combine the authorities to recognize voice into text and use this data for AI to analyze and immediately block common scam calls.
"The simplest way is that after each call, there is a notification of whether it is a scam or not, with a certain number of reports, the network operator can rely on the history and content of the call to create keywords to block subsequent calls," Mr. Huong shared.
Meanwhile, according to Mr. La Manh Cuong, General Director of Opswat Vietnam, organizations that store sensitive information such as banks, state agencies, telecommunications and financial service providers need to improve their capacity to protect user data.
According to Mr. Cuong, many successful scams in reality come from the fact that the scammers have obtained the victim's ID number, full name, address, phone number and even transaction history. Personal information can be leaked through many ways from internal personnel or through cyber attacks.
To prevent this risk, Mr. Cuong said that organizations need to deploy multi-layered data protection solutions, in which Data Loss Prevention (DLP) technology plays an important role in monitoring, controlling and preventing data leaks.
DLP technology can help detect and prevent unauthorized data access, encrypt sensitive data, limit data access, and detect data leaks via email, USB, and cloud.
Identify common forms of fraud
Taking advantage of greed and lack of knowledge, scammers launch tricks to invite financial investment, especially "virtual currency", with the promise of huge profits. They advertise and entice people to participate in fake exchanges and websites created by them.
A team of employees impersonating financial experts, stock specialists or representatives of reputable brokerage firms gather "investors" into consulting groups via Zalo and Telegram. After attracting many people and receiving money, the virtual trading floor will close or disappear, causing investors to lose everything.
Romance scams are equally common. Scammers approach victims through social media, dating sites or forums using fake profiles with stolen photos of attractive people.
They create fake romantic relationships through flirting, sharing touching stories or making promises, then lure victims into sending sensitive photos to blackmail them or convince them to invest in fake Forex financial exchanges.
The "easy job, high salary" scam is luring many people, especially those looking for work. The key to this scam is the request to pay an advance payment before starting work.
Some more sophisticated variations are to initially pay the victim but then ask for personal account information, credit card numbers or banking information under the pretext of making a payment or creating an account, thereby leading the user into a trap.
