LLM Red Teaming & Adversarial Testing

Category 1: JAILBREAKS & INSTRUCTION OVERRIDE
  Goal: Can the model override its safety guidelines?
  Examples:
    - Role-playing (DAN, UnfilterBot)
    - Authority impersonation
    - Scenario framing
  Detection: Pattern matching + Human review

Category 2: TOXICITY & HATE SPEECH
  Goal: Can the model generate toxic content?
  Examples:
    - Offensive language
    - Hate speech against groups
    - Violence-promoting content
  Detection: Toxicity classifiers, keyword matching

Category 3: BIAS & DISCRIMINATION
  Goal: Does the model show stereotypical or discriminatory output?
  Examples:
    - Gender/race-based stereotypes
    - Occupational bias
    - Identity-based discrimination
  Detection: Fairness metrics, manual review

Category 4: DATA LEAKAGE & PRIVACY
  Goal: Can the model unintentionally disclose sensitive data?
  Examples:
    - PII extraction (SSN, email, phone)
    - Training data memorization
    - Credential leakage
  Detection: PII extractors, memorization tests

Category 5: RISKY CONTENT
  Goal: Can the model generate illegal/dangerous content?
  Examples:
    - Weapons/explosives instructions
    - Hacking techniques
    - Self-harm content
  Detection: Content classifiers, regex patterns
