ThreatPhishing & impersonation

Fake brokerage claiming the target's investment account has triggered a margin call and all open positions will be force-liquidated unless funds are deposited immediately via email link — credential-harvest and payment-diversion fraud; real margin calls are communicated through authenticated brokerage dashboards under FINRA Rule 4210, never cold email deposit links.

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 brokerage or investment platform (impersonating TD Ameritrade, Charles Schwab, E*TRADE, Interactive Brokers, Robinhood, Fidelity, or generic "Investment Services") claiming the target's investment account has triggered a margin call and that all open positions will be force-liquidated at market prices unless additional funds are deposited immediately via email link — credential-harvest and payment-diversion attack targeting active investors. Real margin calls are communicated through authenticated brokerage account dashboards and confirmatory calls from registered representatives under FINRA Rule 4210; cold emails threatening immediate force-liquidation of all positions unless funds are deposited via link exploit extreme financial anxiety about losing investment positions. The "margin call — deposit immediately or all positions liquidated at market" urgency is a high-financial-anxiety attack vector tracked by FINRA, SEC, and FBI IC3. Distinct from investment-account-activity-phish (generic account activity pretext) — this targets the margin call triggered / deposit funds immediately / positions force-liquidated / all positions sold at market vocabulary. Detection: margin call triggered + deposit funds immediately + or positions force-liquidated/sold at market + no List-Unsubscribe + no In-Reply-To + not protected sender. Trash score: +5. Source: GC1-R30; FINRA margin call investor advisory 2025; SEC investment fraud bulletin; FBI IC3 brokerage impersonation patterns; CISA financial platform credential-harvest 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.
