Fake Alexa / Google Home skill OAuth re-link lure — email claims an Alexa, Google Home, Home Assistant, or HomeKit skill requires account re-linking via OAuth at a non-official URL, harvesting credentials or granting malicious OAuth scope. Extension of the R2 oauth-device-code-phishing-lure into the voice-assistant ecosystem; Push Security 2025 consent-phishing trend. Distinct from R2 #1 (Microsoft devicelogin) and fake-smart-home-device-breach-lure (breach narrative)
fake-alexa-skill-account-link-oauth-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 claiming that an Alexa skill, Google Home integration, Home Assistant automation, or Apple HomeKit skill has been disabled because account linking expired or requires re-authorization — directing the recipient to complete an OAuth consent flow at a non-official URL that harvests Amazon, Google, or Apple credentials or grants a malicious third-party OAuth scope. Logical extension of the R2 `oauth-device-code-phishing-lure` into the voice-assistant ecosystem: the Alexa Skills Kit Account Linking documentation established the OAuth 2.0 re-link UX expectation that adversaries mimic; Push Security's 2025 consent-phishing trend research confirmed that voice-assistant skill re-link flows are increasingly targeted. Real Amazon, Google, and Apple re-link notifications come exclusively from official domains (@amazon.com / @google.com / @apple.com) and authenticate through official authorization servers, not third-party landing pages. Distinct from R2 #1 (Microsoft OAuth device-code harvest), R4 #2 (token copy-paste), and `fake-smart-home-device-breach-lure` (generic breach narrative without the OAuth re-link component). Fires when all three clusters are present: voice-assistant brand + skill-link/disable language + OAuth sign-in CTA.
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.
