ThreatPhishing & impersonation

Fake bank notice claiming unusual activity was detected and requiring identity verification within 24 hours to prevent account suspension — credential-harvest phishing; real banks never request full credential re-entry via cold email link under a 24-hour suspend-or-verify deadline.

What this tier means

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

How Gorganizer detects this

Fake bank security notice (impersonating a generic bank, Chase, Bank of America, Wells Fargo, Citibank, or regional institutions) claiming unusual or suspicious activity was detected on the target's account and requiring identity verification within 24 hours via email link to prevent account suspension — credential-harvest phishing. Real banks never request full login credential re-entry via a cold inbound email link under a 24-hour suspend-or-verify ultimatum; account security actions are handled exclusively through the bank's authenticated online banking portal, official mobile app, or verified customer-service phone number. The "unusual activity detected — verify identity within 24 hours to prevent suspension" pattern is one of the most persistent phishing templates across APWG phishing reports since 2018 and accounts for a significant fraction of all financial-sector phishing volume. Distinct from bank-account-suspension-phish (account already suspended / restoration pretext) — this targets the unusual-activity-detected / 24-hour verification window / prevent-suspension pretext specifically. Detection: unusual/suspicious activity detected + verify identity within 24 hours + prevent account suspension vocabulary + no List-Unsubscribe + no In-Reply-To + not protected sender. Trash score: +4. Source: GC1-R28; APWG phishing report Q1 2026 (banking sector); FTC bank impostor scam advisory 2025; CISA banking phishing consumer guidance; OCC phishing threat alert.

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.
