Phishing link injected into legitimate reply thread

reply-chain-hijack-link-lure

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 is a genuine reply (valid In-Reply-To or References header) but contains a phishing-grade link: a lookalike domain, brand in subdomain, brand in path, suspicious TLD, or dangerous URL scheme. Attackers who hijack legitimate email threads often use link-only lures (no attachment) to evade attachment-focused scanners while exploiting the implicit trust of a known conversation thread. Score: +2 trash (lower than attachment variant because link-only is less certain).

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.
