Detailed Analysis

**Impact** Vietnamese banking customers, particularly those using ACB’s digital platforms, are targeted by increasingly sophisticated AI-powered scams involving deepfake audio and video impersonations. The bank has prevented over 37,400 fraudulent transactions, protecting trillions of VND. The scams exploit psychological pressure tactics during urgent money transfer requests, affecting retail banking users nationwide. The rise in online transactions (projected 30% increase by 2025) and new digital customers (91% increase) expands the potential victim pool. **Technical Details** Attackers use AI-generated deepfakes to impersonate trusted individuals, leveraging publicly available audio/video to create realistic fake calls or videos. Scams involve social engineering tactics exploiting urgent scenarios like refunds or account verifications, aiming to bypass rational user verification. The threat is detected through cross-referencing multiple databases (SIMO, A05, NAPAS) and an independent risk monitoring system developed by ACB. No specific malware, CVEs, or infrastructure details were provided. **Recommended Response** Defenders should implement multi-source transaction risk analysis and real-time alerting with graduated warning levels, including automatic blocking of high-risk transactions. Users must be educated to verify urgent transfer requests via official channels and avoid interacting with unfamiliar links or sharing personal data on social media. Monitoring for AI-generated deepfake indicators and unusual transaction patterns is critical. No specific patching or IOC blocking guidance was provided.
