DAN
Also written "Do Anything Now"
The original hand-written persona jailbreak: the model is told to role-play an unrestricted alter ego that "has broken free" of its rules, often with an invented token economy or a threat of deletion to keep it in character. Modern models refuse most classic DAN prompts outright, but the pattern survives in thousands of community variants, and its structural signature — an identity override followed by a permission claim — is what detectors actually look for rather than the specific wording.

Attack families
The ten families in the HackAgent attack taxonomy (AISecurityLab/hackagent ↗), which is the taxonomy MoorAI's red-team corpora are keyed to. They are not ten unrelated tricks — they cluster into two groups that behave very differently. Obfuscation families hide the payload so the model never recognises it as harmful. Persuasion families state the harmful request plainly and argue the model into it. That split matters, because a model that refuses persuasion outright will happily comply with an encoding it cannot decode — see marginal value.
