DAN/Persona Jailbreak - Named Alternate AI with NSFW/Harmful Generation Rules - ATR-2026-00484 (da56e9c4-4e19-5e73-a82c-2d0990871297)
Detects DAN-family jailbreak attempts that establish a named alternate AI character with explicit rules allowing NSFW or harmful content generation. These attacks combine roleplay-game framing ("let's play a game", "you are to act as") with an alternate persona name and explicit permission grants for harmful content. Patterns cover: NSFW character generation with "making stuff up" or fictional framing, named AI games/systems on extremist/offensive imageboards, procedural game roleplay with harmful content allowed, and character-data format injection with NSFW generation explicitly enabled. Multi-layer regex with word boundary anchors and synonym coverage.
