Brinztech Alert: Data of NAPAS are on Sale

Dark Web News Analysis

A threat actor on a known cybercrime forum is making an extremely serious claim to be selling data that they allege was stolen from the National Payment Corporation of Vietnam (NAPAS). According to the seller’s post, they successfully exploited NAPAS’s internal portal and are now offering the exfiltrated user data for sale.

This claim, if true, represents a national financial security crisis for Vietnam. NAPAS operates the country’s central interbank payment system, connecting the majority of Vietnam’s commercial banks. A breach of their internal systems is not a standard data leak; it is a systemic, national-level event. It poses a catastrophic supply chain risk to every single financial institution that relies on the NAPAS network and could expose the sensitive financial and personal data of millions of Vietnamese citizens and businesses.  

Key Cybersecurity Insights

This alleged data breach presents a critical and systemic threat to Vietnam’s financial system:

• A Catastrophic Threat to National Financial Infrastructure: The most severe risk is the compromise of a national payment switch. An attacker with access to this core infrastructure could potentially disrupt the entire Vietnamese financial system, causing widespread economic chaos and a loss of confidence in the banking sector.
• Severe Supply Chain Risk for All Vietnamese Banks: A compromise of NAPAS is a direct and severe supply chain attack on every bank and financial institution in Vietnam that uses its services. Data stolen from the central switch could be used to launch highly sophisticated attacks against all of these connected banks.
• High Risk of Mass Financial Fraud: The “user data” from a national payment corporation would be the most sensitive financial PII imaginable. If this data is legitimate, it would provide criminals with a powerful tool to commit mass financial fraud and identity theft against a huge portion of the Vietnamese population.

Mitigation Strategies

In response to a threat of this magnitude, the Vietnamese government and its financial sector must take immediate and decisive action:

• Launch an Immediate National Emergency Investigation: The State Bank of Vietnam, in coordination with NAPAS and national cybersecurity authorities, must immediately launch a top-secret, highest-priority investigation to verify this extraordinarily severe claim.
• Activate a Coordinated Financial Sector Incident Response: All banks and financial institutions in Vietnam must be immediately placed on the highest alert. They need to activate their incident response plans, with a specific focus on threats originating from the national payment network. All transactions should be subject to enhanced scrutiny and fraud monitoring.
• Mandate a Comprehensive Security Overhaul of Critical Financial Infrastructure: This incident, if confirmed, must trigger a complete, mandatory, top-to-bottom security audit of all of Vietnam’s critical financial infrastructure. This includes securing the central switch and reviewing the security of all connected member banks.
