Proposed New Regulations to Tighten Control Over Banking Apps

The State Bank of Vietnam is currently seeking public input on a draft Circular amending and supplementing certain provisions of Circular 50/2024/TT-NHNN, which governs safety and security standards for online services in the banking sector. This latest draft focuses on expanding the scope of regulation, incorporating international technical requirements, and enhancing protections for both individual and corporate customers in electronic transactions.

According to the draft, the scope of application has been expanded to include mobile money service providers, in addition to credit institutions, foreign bank branches, payment intermediary service providers, and credit information companies.

A notable new requirement is that online banking and mobile banking applications (commonly known as banking apps) must comply with the international OWASP security standards, addressing the top 10 most common vulnerabilities (OWASP Top Ten) and ensuring mobile application security (OWASP Mobile Application Security).

Significantly, banks are mandated to regularly monitor mobile banking app versions at least every two months, disallowing the use of versions older than two generations from the latest release. Customers are required to reinstall the latest version when activating a new device or upon detection of a security vulnerability. Additionally, measures must be in place to prevent downgrading to older versions.

New regulations enhance the safety and security of banking apps.

Upon identifying security vulnerabilities, banks must implement checks, block transactions, and promptly address, rectify, and update to the latest version. Applications must also automatically cease operation if a simulated environment, malware interference, or a rooted/jailbroken device is detected. The State Bank of Vietnam stated that these version control measures aim to limit or eliminate outdated or vulnerable versions.

The draft introduces mandatory biometric verification for changes to organizational customer identification information, in line with Directive 139/CĐ-TTg, to combat fraud involving the establishment of fake companies for payment accounts.

In electronic transaction confirmation, the drafting agency has removed standard electronic signatures, retaining only secure electronic signatures, digital signatures, or foreign electronic signatures recognized in Vietnam, aligning with the 2023 Law on Electronic Transactions and Decree 23/2025/NĐ-CP.

The appendix in the draft, which categorizes online payment transactions, has been refined to clearly distinguish between transaction types A, B, C, and D based on value, limits, and customer groups. It also mandates additional biometric verification for high-value transactions or newly established organizational customers.

The issuance of the amended Circular is expected to strengthen the security of the digital banking system, protect users from cybercrime risks, and establish a unified legal framework for emerging models such as mobile money, biometric authentication, and internationally standardized security practices.
