Post-meeting finance request BEC chain — email contains both calendar/meeting confirmation language and urgent wire transfer or payment instruction, suggesting a "spoofed-CEO meeting-invite → follow-up wire request" attack chain
calendar-authority-bec-chain
What this tier means
High-confidence threat indicator — phishing, impersonation, BEC, or scam pattern. Strong contributor to the trash decision.
How Gorganizer detects this
Detects the "calendar invite → finance request" BEC chain where attackers first send a meeting invite to establish authority, then follow up with a wire transfer or ACH payment request. The victim's acceptance of the invite (or reference to a prior meeting) is used to lower guard before the financial attack. Combined calendar-meeting language AND finance-urgency language in the same message is a strong BEC indicator even when the sender domain passes other checks. Does not fire when List-Unsubscribe is present (bulk mailers) or when email is a reply.
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.
