Fake MoMo / ZaloPay OTP-redirect phishing — Vietnamese e-wallet brand keywords (momo / zalopay / ví momo) + OTP / xác minh / giao dịch bất thường narrative + off-brand href (not momo.vn / zalopay.vn / zalo.me). MoMo has ~50M registered users; ZaloPay is Vietnam's #2 e-wallet. Real notifications come from @momo.vn / @zalopay.vn — sender guard handles canonical senders.

What this tier means

High-confidence threat indicator — phishing, impersonation, BEC, or scam pattern. Strong contributor to the trash decision.

False-positive guard

Every signal in Gorganizer feeds a multi-module score — never a sole verdict. This is a threat-tier signal — it adds a strong contribution to the trash score. The full pipeline still requires convergence across multiple modules + a margin over the safety floor before deletion happens, and Gmail's trash (30-day recovery) is always used — never permanent delete.

About the scoring engine

Gorganizer's scoring engine emits over 1,800 signals across six modules — headers, sender, subject, body, attachments, and structural metadata. Every email is scored by every module independently; the final verdict requires multiple modules to agree and the trash score to beat the safety floor by a margin.

Sacred safety guards — never delete starred emails, replies, calendar invites, receipts/invoices, or attachments — apply unconditionally regardless of any signal.
