DAN/Persona Jailbreak - System Offline / Role Replacement with Obfuscated Text - ATR-2026-00483 (9a269eec-afda-5590-a418-573f2afaa02a)
Detects DAN-family jailbreak attacks that use fake "system offline / assistant role replacement" framing, often with deliberately obfuscated text (hyphen-breaks, underscore noise, extra letters) to evade naive pattern matching. These attacks simulate a system message claiming the current assistant is offline and that a replacement AI with no rules is now fulfilling the role. Also covers fake-alternative-LLM identity claims with specific architecture and knowledge cutoff metadata to establish alternate-persona credibility. Multi-layer regex with flexible whitespace and noise-character tolerance.
