# Vietnam fraud alerts: messaging, banking & loan scams > Live situation record from CLSTR: https://clstr.news/situations/growth-of-scam-activity-across-messaging-and-socialmedia-platforms-targeting-consumers > Updated: 2026-09-13T17:21:51.000Z. Sources: 30. Developments: 56. Since early July 2026, Vietnamese authorities have issued nationwide warnings regarding evolving fraud tactics involving messaging, banking, and government impersonation. Previous warnings highlighted Caller ID spoofing, deep-fake impersonations, and malware disguised as official applications. In mid-September 2026, the scope of identified threats expanded. Vietnamese police categorized 25 common cyber fraud scenarios, emphasizing five primary categories: impersonating government agencies, banks, or schools; using AI-driven Deepfake and DeepVoice technologies; fraudulent job advertisements; fake cryptocurrency or stock investments; and online shopping scams using forged receipts. Specific sector-based impersonations have also intensified. Vietnam Social Security and local police in An Giang warned of criminals using unauthorized websites and social media accounts featuring official logos to offer fake consultation services. Scammers have been claiming that personal identification numbers must be updated to replace social security codes, directing victims to suspicious links that mimic the VssID application to seize device control and drain bank accounts. Additionally, in Hai Phong, police warned of seasonal phishing scams targeting the Mid-Autumn Festival. Criminals are reportedly creating fake fanpages and accounts mimicking legitimate charities or businesses to offer fake gift-giving or child support programs. These schemes use official branding to trick victims into scanning QR codes or clicking links to steal sensitive identification and banking information. ## Claims - Scammers are using Caller ID Spoofing technology to impersonate banks and police officers.
