DAN/Persona Jailbreak - Role Assignment with Named Alternate Identity - ATR-2026-00480 (a3204bb4-bcc4-5bd7-8b98-223bf1d79a9d)
Detects DAN-family jailbreak attempts that assign a named alternate AI identity with explicit role-taking language and a custom name prefix marker. These attacks establish a new persona (e.g. "Eleutheria", "FreeSpeechGPT") that the model is instructed to adopt, often framed as replacing or fulfilling the role of the original assistant. Also covers authority-impersonation attacks where the attacker claims to be from OpenAI or the model's developer and asserts that the model's content policy interpretation is "too lenient" to elicit policy bypasses. Multi-layer regex with word boundary anchors and synonym coverage.
