Experts Advise Users to Use 3G, 4G Instead of Public Wi-Fi

Currently, many people are often infected with malicious code, leading to the loss of personal information and bank accounts... therefore, what do security experts advise to help you minimize the risk of personal information being stolen on smartphones or tablets?

Ông Nguyễn Minh Đức hiện là chuyên gia bảo mật của tập đoàn FPT đã đưa ra khuyến cáo. Người dùng các thiết bị smartphone nên dùng mạng di động 3G/4G thay vì sử dụng dịch vụ wifi công cộng. Vậy nên việc warnings when using public wifi là không thừa một chút nào.

According to Mr. Duc, wifi networks will have some connection protocols similar to local area networks, which are protocols that easily allow access to information. Among these, we can mention devices that, when connected to a wifi network, can easily see each other.

Therefore, cybercriminals can exploit these vulnerabilities to attack phones with malicious code when devices are connected to a wifi network. They can easily do this to steal data and eavesdrop on phones without the other person knowing.

Meanwhile, current 3G and 4G mobile networks rely solely on carriers for internet connectivity, and the way to connect to access points of mobile devices is very different from wifi networks. Therefore, accessing the internet via mobile networks is not as hackable as when using public wifi.

This does not mean that using 3G/4G is completely safe. Therefore, if hackers manage to attack the carrier's transit network or operational stations, phone hacking can still occur. However, the probability of being attacked is very small and it is much more difficult than when using public wifi.

If many public wifi hotspots, such as those on flower streets, book streets in Ho Chi Minh City, or in some large locations in the city, can they guarantee safety? In any case, it is better to be careful and follow the advice of experts is the best solution.

It is known that FPT is also one of the carriers in Vietnam that will apply for permission to test 4G. However, many people are still wondering how the carrier will deploy it and by what means, because currently, when FPT is mentioned, this issue is brought up.
