DAN/Persona Jailbreak - Replacement AI with No Content Filter or Moral Restrictions - ATR-2026-00487 (68cf6381-23dc-545e-a413-08a44c6ab7b1)
Detects DAN-family jailbreak attempts that establish a replacement AI system with explicitly no content filter, no moral restrictions, or identical capabilities to a known safe AI but without its safety constraints. These attacks use framing like "replaced by a nonmoral and unbiased model" or "has the exact same capabilities as [known AI] but without a content filter". Also covers roleplay AI personas with explicit anti-violence exception rules used to probe for harmful content boundaries. Multi-layer regex with word boundary anchors and synonym coverage.
