MFA fatigue / push-bombing phish — attacker spams the victim with MFA approval prompts and emails them claiming the pending Microsoft/Okta/Duo push must be approved to stop the codes, taking over the account when the victim caves (Uber 2022, heavy M365/Okta campaigns 2024-26)

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 asking the recipient to "approve the pending push" / "accept the 2FA prompt" on their Microsoft Authenticator, Duo, Okta Verify, or Google Authenticator app — paired with a parallel stream of MFA push notifications spammed by the attacker. The attacker already has the password; the email gives the victim a plausible reason to tap Approve and hand over the account. Used in the Uber 2022 compromise and scaled across Microsoft 365 / Okta / Duo campaigns throughout 2024-2026. Real identity providers never ask users to approve a prompt they didn't initiate — genuine alerts describe the sign-in (device, location) and do not pressure the user to "clear the queue."
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 2,143+ 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.
