AI Agent Incident Response Playbook 2026: When Your Agent Gets Compromised
AI agent incident response requires specialized procedures because compromised agents operate differently than traditional security incidents. An agent can cause damage autonomously, access multiple systems simultaneously, and behave in unpredictable ways when manipulated.
This playbook provides step-by-step guidance for responding to AI agent compromises.
Why AI Agent Incidents Are Different
- Speed — Agents can execute multiple actions in seconds
- Autonomy — No human oversight during the incident
- Blast radius — One agent may have access to multiple systems
- Unpredictability — Manipulated agents behave erratically
- Evidence complexity — Logs may be incomplete or manipulated
⚠️ Critical: Every AI agent deployment should have a documented kill switch procedure before going to production. If you don't have one, stop and create it now.
Detection: How to Know Your Agent Has Been Compromised
Signs of compromise:
- Unexpected tool calls or API requests
- Unusual data access patterns
- Agent producing outputs inconsistent with instructions
- External connections to unknown endpoints
- Monitoring alerts for anomalous behavior
- User reports of strange agent responses
- Credential usage from unexpected locations
The 5-Phase Incident Response Playbook
Phase 1: Identification and Triage (0-15 minutes)
- Confirm the incident — Verify signals indicate actual compromise, not false positive
- Assess severity — Critical (active data exfiltration), High (unauthorized access), Medium (policy violation)
- Identify affected agents — Determine scope: single agent or multiple
- Activate incident response team — Notify security team, agent owners, and management
- Begin evidence preservation — Ensure logs are being captured
Phase 2: Containment (15-60 minutes)
- Execute kill switch — Halt all agent activity immediately
- Revoke credentials — Invalidate API keys, tokens, and certificates
- Isolate network access — Block agent from accessing external networks
- Preserve state — Capture agent state before shutdown if safe
- Block indicators of compromise — Add malicious inputs/outputs to blocklists
Phase 3: Forensic Investigation (1-24 hours)
- Collect evidence — All logs, conversation history, tool calls, data accessed
- Reconstruct timeline — When did compromise start, what actions were taken
- Identify attack vector — Prompt injection, credential theft, supply chain, other
- Assess impact — What data was accessed, what actions were taken
- Identify root cause — How did the attacker gain control
Evidence to collect:
- Complete conversation logs
- Tool invocation records with timestamps
- Data access logs
- User inputs that triggered the incident
- External communications initiated by agent
- Agent configuration at time of incident
Phase 4: Recovery and Hardening (24-72 hours)
- Apply patches — Fix vulnerabilities that enabled the attack
- Strengthen defenses — Improve prompt injection protection, monitoring
- Rotate credentials — All credentials the agent had access to
- Test thoroughly — Verify fixes before redeploying
- Reduce permissions — Apply least-privilege rigorously
- Deploy enhanced monitoring — Add alerts for indicators discovered
Phase 5: Post-Incident Review (Within 1 week)
- Document timeline — Complete incident chronology
- Identify lessons learned — What worked, what didn't
- Update procedures — Improve incident response playbook
- Share indicators — Contribute to threat intelligence community
- Schedule follow-up audit — Verify remediation effectiveness
Runbook Templates for Common Incident Types
- Prompt injection detected — Focus on containment and input analysis
- Data exfiltration suspected — Focus on access logs and data scope
- Unauthorized tool usage — Focus on permission boundaries
- Agent behavior anomaly — Focus on configuration and model state
