On the afternoon of September 11, the Vietnam Cyber Emergency Response Center (VNCERT) announced a personal data leak incident at the National Credit Information Center (CIC).

Accordingly, the initial verification results show signs of cybercrime attacks and intrusions to steal personal data. The amount of illegally appropriated data is being continuously counted and clarified.

On September 12, the Research, Consulting, Technology Development and International Cooperation Department of the National Cyber Security Association (Technology Department) received a number of questions and concerns from members about whether the incident at CIC would affect the banking system, especially accounts and credit cards.

Many members are also concerned about whether users need to lock their cards or change their bank passwords to ensure safety.

Representative of the Technology Department of the National Cyber Security Association, Mr. Vu Ngoc Son affirmed: "Through preliminary assessment of the situation, Vietnam's banking and credit system is still safe, tightly protected and operating stably.

People do not need to take measures such as locking cards, locking accounts, changing CVC/CVV codes or changing passwords just because of concerns based on unofficial information on the internet. These actions do not help increase security, but on the contrary, can disrupt transactions and directly affect daily life.

In addition, the National Cyber Security Association also warned of the risk of bad actors taking advantage of this event to impersonate banks and authorities to commit fraud, spread malware or appropriate users' information and assets.

Bad guys can make fake calls or text messages to ask users to provide personal information, credit cards, CVV/CVC authentication codes, OTP security codes, etc. Users should note that banks absolutely do not ask customers to perform these operations through unofficial channels.

Users should also not share or disseminate unofficial, unverified information on cyberspace, especially information related to the type and quantity of leaked data because the authorities are still in the process of investigating and clarifying.

"We should only monitor and receive official information from competent authorities," the expert emphasized.
