Masquerading filename (e.g. invoice.pdf.exe)

double-extension-masquerade

What this tier means

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

How Gorganizer detects this

Attachment filename has a document-looking extension (.pdf, .docx, .jpg, etc.) followed by an executable extension (.exe, .scr, .js, .jar, etc.). Example: "invoice.pdf.exe". Windows hides the final extension by default, so users see "invoice.pdf" and trust it. Real documents never have an executable extension appended — this shape is exclusively malware delivery.

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.
