Fake NFT bid / offer notification phish — email impersonates OpenSea, Blur, or Magic Eden with a fake "you received a bid" or "your listing sold" hook, directing to a drainer dApp for ERC-20 approval or seed-phrase entry. Chainalysis 2026; Certik Q1 2026.

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 impersonating OpenSea, Blur, MagicEden, Foundation, or another NFT marketplace notification system claiming the recipient's listed NFT received a bid and directing them to accept/review at an off-platform URL — which leads to a wallet-connection page triggering a setApprovalForAll drain. This signal fills the gap between the existing fake-nft-whitelist-mint-wallet-drain-phish (which targets NFT buyers via fake whitelist/presale/mint opportunities) and this signal targeting NFT sellers receiving fake bid notifications. Abnormal Security's March 2026 threat intelligence report documented bulk OpenSea/Blur bid-notification template cloning; Bitdefender's BlurBid campaign report (February 2026) traced coordinated fake-Blur bid emails; Recorded Future's March 2026 research identified bid-notification phishing kits in phishing-as-a-service markets. Legitimate NFT marketplace bid notifications come from verified senders with DKIM signing, List-Unsubscribe headers, and links exclusively to official marketplace URLs.
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.
