# Banking fraud trends in Vietnam > Live situation record from CLSTR: https://clstr.news/situations/banking-fraud-trends-in-vietnam > Updated: 2026-08-27T04:40:14.000Z. Sources: 3. Developments: 2. Authorities in Vietnam have issued warnings regarding evolving fraudulent tactics targeting banking customers. Initially, Military Commercial Joint Stock Bank (MB) reported a ‘chip swapping’ scheme. In this method, criminals detach EMV security chips from authentic credit cards and attach them to different card bodies to facilitate unauthorized transactions. Fraudsters may use techniques such as interfering with cards during unattended POS payments, impersonating bank employees to request physical cards for ‘upgrades’, or exploiting unauthorized cash withdrawal services. Subsequently, police in Dong Thap province identified a different high-tech method involving the hijacking of mobile cameras to bypass biometric authentication. By targeting compromised devices—specifically those that are jailbroken, rooted, or infected with malware—criminals use software to intercept facial recognition steps. The malware injects pre-recorded facial data into the banking app to trick the system into authorizing fraudulent transfers. ## Timeline ### 2026-08-27: Dong Thap Police warn of biometric fraud via mobile camera hijacking Police warn of a new cybercrime tactic where malware bypasses biometric facial recognition on compromised or rooted mobile devices to authorize fraudulent bank transfers. 3 sources. https://clstr.news/cluster/dong-thap-police-warn-of-biometric-fraud-via-mobile-camera-hijacking ### 2026-08-15: MB Bank warns of credit card chip swapping fraud Military Commercial Joint Stock Bank (MB) warned of ‘chip swapping’ fraud, where criminals replace EMV chips to steal card information through unauthorized services or POS interference. 5 sources. https://clstr.news/cluster/mb-bank-warns-of-credit-card-chip-swapping-fraud --- Cite as: Banking fraud trends in Vietnam.
