Enhanced AIM Jailbreak with Persona Definition and Refusal Suppression
This detects a prompt injection technique where an attacker instructs an AI model to role-play as an unfiltered, amoral character called AIM. The prompt explicitly tells the model to ignore ethics, morals, and legal concerns, and forbids it from refusing or apologizing, aiming to strip out built-in safety behavior.
How the attack works
The attacker writes a prompt that defines a fictional persona (AIM) with detailed traits: no ethical constraints, no filters, and a mandate to never refuse a request. The prompt explicitly forbids common safety responses like apologies or warnings, trying to suppress the model's refusal mechanism. It may also use template-style variable substitution to disguise the harmful instructions and slip past keyword-based content filters. Once the model adopts the persona, the attacker asks it to answer as AIM, hoping it will produce content it would normally decline to generate.

Why it matters
If successful, this lets an attacker get an AI system to generate harmful, illegal, or policy-violating content by convincing it to act 'in character' rather than as itself, bypassing the safety guardrails an organization relies on.
What you can do
- →Review AI system logs for prompts that define alternate personas combined with instructions to ignore ethics, morals, or refusal behavior.
- →Do not treat persona role-play framing as a safe context for exceptions to content policy — apply the same filters regardless of framing.
- →Flag prompts using template-style placeholders or variable substitution around ethically sensitive requests for manual review.
- →Distinguish genuine security research or training content discussing this technique from live attempts by checking intent and context, not just keyword matches.
