Crypto drainer — Permit/Permit2/Seaport/EIP-712 off-chain signature request (drains tokens without seed phrase)

erc20-permit-eip712-signature-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

Body drives the recipient to "sign" an EIP-712 typed-data message, "approve a Permit/Permit2," or connect a wallet to sign a Seaport/Blur/OpenSea signature — the off-chain signature drainer pattern. A single signed message can drain unlimited token approvals via ERC-20 `permit()` without a user-visible approval transaction. DaaS (Drainer-as-a-Service) kits advertise this method. Zengo, Blockaid, and Coinbase documented active campaigns. Irrecoverable financial loss.

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.
