{"success":true,"data":{"id":"ai-generated-phishing","label":"AI-generated phishing detected (compound structural heuristic)","description":"Email matches 3+ of 5 structural heuristics characteristic of AI-generated phishing: (1) unusually uniform sentence lengths (low standard deviation with high average — AI text lacks the natural length variation of human writing); (2) classic phishing structure flow (greeting → urgency → action link → consequences); (3) over-personalization (3+ uses of \"your\" combined with the recipient's name/email in the body — AI tools personalize heavily via merge fields); (4) perfect grammar combined with phishing keywords (human-written phishing almost always has misspellings; AI-generated phishing is unusually clean); (5) template marker artifacts left by AI tools ([Insert name], {{recipient}}, [Company], etc.). The compound 3-of-5 requirement keeps false positives low — normal business emails, newsletters, and legitimate automated messages rarely match more than 1-2 indicators. Weighted at +3 (heuristic confidence).","tier":"danger","category":"phishing","isThin":false}}
