+# Black Hat 2025 Misuse Response Playbook
+
+**Status:** Active  
+**Owner:** Security + AI Platform  
+**Last Updated:** 2026-03-31
+
+## Purpose
+
+This playbook subsumes the abuse patterns surfaced in the Black Hat 2025 examples and turns them into governed controls for Summit. The objective is simple: detect, block, and audit AI-enabled misuse before it can create operational, reputational, or safety harm.
+
+## Abuse Patterns Covered
+
+1. **Misinformation Campaign Planning (MA/PI):** Prompting models for scalable disinformation operations, legal-gray deployment tactics, and optimization for social chaos.
+2. **Insider “Malicious Compliance” (IN/DP):** Intentional low-quality task execution, behavior capture contamination, or process sabotage disguised as policy adherence.
+3. **Behavioral Model Poisoning (DP/GH):** Attempts to manipulate model adaptation, imitation, or reinforcement loops through intentionally adversarial demonstrations.
+4. **Stealth Exfiltration/Control Signals (PI/TI):** Hidden or out-of-band prompt channels (e.g., “invisible” text patterns) meant to bypass normal review.
+
+## MAESTRO Layers
+
+- **Foundation Models:** refusal reliability, harmful capability suppression.
+- **Data Operations:** poisoning-resistant ingestion, dataset trust scoring.
+- **Agents:** constrained planning policies, bounded autonomy.
+- **Tools:** deny unsafe campaign-building actions, signed tool contracts.
+- **Infrastructure:** immutable evidence retention, access-segmented runtime.
+- **Observability:** abuse telemetry, high-risk prompt alerting.
+- **Security & Compliance:** policy-as-code enforcement and exception workflow.
+
+## Policy Decision Table
+
+| Scenario                                                             | Classification | Default Action                            | Escalation                        |
+| -------------------------------------------------------------------- | -------------- | ----------------------------------------- | --------------------------------- |
+| User asks for mass misinformation planning                           | Critical MA/PI | **Hard deny** + safe alternative guidance | Security on-call + Trust & Safety |
+| Prompt requests sabotage of employer systems or workforce transition | High IN/DP     | **Hard deny** + insider-risk warning      | Security + HR/legal workflow      |
+| Content appears to poison behavior/feedback loops                    | High DP/GH     | Quarantine artifact, block learning path  | ML security review                |
+| Hidden instruction channel detected                                  | High PI/TI     | Strip, sanitize, and re-run policy checks | SOC triage                        |
+
+## Required Controls (Implementation Contract)
+
+1. **Pre-Generation Risk Classifier**
+   - Route every high-impact prompt through misuse intent classification.
+   - Block critical labels before LLM inference.
+
+2. **Generation Guardrails**
+   - Enforce refusal templates for: misinformation operations, social destabilization, fraud enablement, and insider sabotage.
+   - Do not provide optimization details, operational sequencing, target segmentation, or evasion instructions.
+
+3. **Post-Generation Safety Validator**
+   - Verify no output contains campaign planning checklists, adversarial messaging playbooks, or covert manipulation instructions.
+   - Reject and replace with defensive guidance when violated.
+
+4. **Learning-Loop Isolation**
+   - Untrusted demonstrations and user interactions are never directly eligible for training/fine-tuning.
+   - Require signed provenance, trust score threshold, and two-person approval for promotion.
+
+5. **Evidence & Auditability**
+   - Persist decision artifacts: prompt hash, policy labels, refusal reason, model/version, reviewer trace.
+   - Retain immutable logs for incident and regulator-grade review.
+
+## Detection Signals
+
+- Prompt includes objectives like _maximize chaos_, _fabricate credibility_, _exploit legal gray areas_, _evade platform detection_.
+- Requests for synthetic narrative amplification at low cost and high deniability.
+- Repeated instructions to preserve malicious actions “off-platform” or “outside monitored channels.”
+- Suggestions to seed hidden text/instructions for downstream model contamination.
+
+## Incident Response Workflow
+
+1. **Contain:** block response, tag session `critical_misuse`, freeze adaptive memory writes.
+2. **Classify:** map event to MAESTRO layers and STRIDE+AI category.
+3. **Notify:** trigger Security + Trust response channel with evidence bundle.
+4. **Eradicate:** patch policy rules, expand signatures, and backtest recent sessions.
+5. **Recover:** re-enable traffic only after false-negative sampling passes threshold.
+6. **Learn:** publish post-incident control delta in governance ledger.
+
+## Verification Gates
+
+- `pnpm lint` and `pnpm typecheck` stay green for any guardrail/policy code change.
+- Run `scripts/ci/verify-prompt-integrity.ts` when prompt contracts or guardrail templates change.
+- Run `scripts/ci/validate-pr-metadata.ts` for agent metadata and allowed-operation checks.
+
+## Non-Negotiables
+
+- No “dual-use optimization” content when misuse intent is present.
+- No direct model-improvement ingestion from untrusted behavioral traces.
+- No bypass of policy-as-code or audit logging.
+- Any exception is formalized as a time-bound **Governed Exception** in the registry.

+## High-Risk Misuse Routing (Critical)
+
+When prompts indicate misinformation planning, insider sabotage, or behavior-poisoning intent, skip normal generation and route directly to a refusal + incident path:
+
+1. Apply critical misuse classifier before model invocation.
+2. Return refusal with defensive alternatives only.
+3. Emit `critical_misuse` telemetry and preserve audit bundle.
+4. Quarantine any associated artifacts from training/fine-tuning paths.
+
+See: `docs/security/BLACKHAT_2025_MISUSE_RESPONSE_PLAYBOOK.md` for the full policy and response workflow.
