According to Vice President of Bkav Ngo Tuan Anh, it is quite easy to establish a virtual call center using either a domestic or foreign number with a reasonable price. It is also simple and convenient to acquire a telecoms package via a Voice-over-Internet-Protocol service (VoIP) for scamming purposes, which is then hard for state officials to track criminal activities.
There are now two popular methods to scam people: using similar hotlines to those of famous companies and sending Brandname SMS. The former can easily trick careless users while the latter is more complicated to apply. Criminals have to use illegal hardware and software sold from other nations to simulate a base transceiver station in order to send fake messages to mobile phone users. They can also hire an SMS Fake Sender ID service for this task.
“In the Industry 4.0 era, criminals even exploit Blockchain technology for fraudulent Initial Coin Offering (ICO), which is originally used to attract capital from the cryptocurrency community to develop certain projects based on the Blockchain technology. In this kind of scam, a certain individual first introduces new cryptocurrency tokens and spreads the news of its strong growth in the future, suggesting that people should buy the tokens and sell them later for profit. This information is not true, and buyers lose a large amount of money”, said CEO of Vbee Ho Minh Duc.
Another infamous type of fraudulence is to meddle with weak official mobile networks to collect OTP modes in bank-related services. Despite not being very common, it has appeared in Vietnam lately, used by skillful hackers without the awareness of both network service providers and banks themselves. Only when a customer contacts a bank to report problems does a bank discover this trick.
The Authority of Information Security under the Ministry of Information and Communications has continuously warned citizens of such cases and is cooperating with the police, functional agencies, telecoms businesses to adopt suitable solutions to handle these crimes.
The act of faking a website in Vietnam recently has become more popular when a criminal purposely uses a website address which is almost the same as an official one of a renowned company for fraudulent activities.
Since users do not learn by heart these addresses, they easily fall into the trap and unintentionally share their confidential information, including account name and passwords. These sensitive data are then used on formal bank websites to ask for an OTP code. When the users carelessly enter their code obtained from their mobile phone on these fake websites, their bank account will be swept out of money.
