Fake Microsoft account unusual sign-in / suspension phish

What this tier means

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

How Gorganizer detects this

Email impersonating Microsoft (account alerts, Microsoft 365, Outlook, Teams) with a fabricated unusual sign-in / suspicious login / account suspension / password-expired notice — directing the recipient to verify credentials or click through to a credential-harvesting page. Microsoft is the #1 most-impersonated enterprise brand globally. APWG 2024: Microsoft / Office 365 credential phishing accounts for 27% of all enterprise phishing; credential harvesting is the primary initial-access vector in 79% of cloud account takeovers.

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.
