Incident Response for AI Agents: Rollbacks, Abuse Handling, and Vendor Outage Playbooks

As AI agents evolve from simple chatbots to sophisticated multi-agent orchestration systems demonstrated at Microsoft Build 2025 and browser-controlling agents like OpenAI's Operator, the attack surface and potential for failures has expanded dramatically. The European Union's AI Act, which took full effect on August 2, 2025, now mandates comprehensive monitoring and evidence collection for AI incidents, making structured incident response not just a best practice, but a regulatory requirement.
The stakes are clear: security researchers now warn that AI browser agents pose a bigger risk than most employees when it comes to data leakage and phishing attacks. Meanwhile, multi-agent systems introduce novel failure modes that traditional ITIL frameworks simply weren't designed to handle.
Understanding AI Agent Incident Taxonomy
A robust AI incident response framework begins with a comprehensive taxonomy that categorizes the unique failure modes of AI agents. Microsoft's research identifies several critical categories that organizations must prepare for:
Primary Incident Categories
Hallucination Harm: When AI agents generate false or misleading information that leads to incorrect business decisions, customer harm, or regulatory violations. This includes factual errors, fabricated data, and misrepresentation of company policies.
Data Leakage: Unauthorized exposure of sensitive information through agent interactions, including customer data, proprietary information, or credentials. Browser-based agents are particularly vulnerable, with security experts noting they can accidentally reveal sensitive information when interacting with adversarial websites.
Prompt Injection: Malicious manipulation of agent behavior through crafted inputs, including:
- Direct prompt injection attacks
- Cross-domain prompt injection (XPIA)
- Agent hijacking through indirect prompts
- Memory poisoning and theft
Tool Misuse: Improper or unauthorized use of connected systems, APIs, or functions, including privilege escalation, unauthorized data access, and execution of restricted operations.
Vendor/Model Outage: Service disruptions from AI model providers that affect agent functionality, including API downtime, rate limiting, and model degradation.
Novel Multi-Agent Risks
As organizations adopt multi-agent orchestration systems, new categories emerge:
- Agent compromise and impersonation
- Multi-agent jailbreaks
- Agent flow manipulation
- Insufficient isolation between agents
- Resource exhaustion from agent interactions
Severity Classifications and Key Performance Indicators
Establishing clear severity levels and measurable KPIs is essential for effective AI incident response. Organizations should implement a four-tier severity system:
Severity Levels
Critical (P0): Incidents causing immediate safety risks, major data breaches, or complete system failure
- Example: Agent accessing and sharing customer financial data
- Response time: Immediate (within 15 minutes)
- Escalation: CEO/CISO notification required
High (P1): Significant business impact with customer-facing consequences
- Example: Agent providing incorrect medical advice or financial guidance
- Response time: Within 1 hour
- Escalation: Director-level notification
Medium (P2): Moderate business impact with internal consequences
- Example: Agent workflow failures affecting productivity
- Response time: Within 4 hours
- Escalation: Manager-level notification
Low (P3): Minor issues with minimal business impact
- Example: Agent performance degradation
- Response time: Within 24 hours
- Escalation: Team-level handling
Critical KPIs
Mean Time to Detection (MTTD): How quickly incidents are identified
- Target: <5 minutes for P0, <30 minutes for P1
- Measurement: Time from incident occurrence to alert generation
Mean Time to Response (MTTR): How quickly response actions begin
- Target: <15 minutes for P0, <1 hour for P1
- Measurement: Time from detection to first response action
Rollback Success Rate: Percentage of successful fallback implementations
- Target: >99% for automated rollbacks
- Measurement: Successful rollbacks / Total rollback attempts
Customer Impact Metrics: Business impact assessment
- Affected users, revenue impact, compliance violations
- SLA breach incidents and regulatory reporting requirements
Technical Response Mechanisms
Kill Switches and Circuit Breakers
Implement multiple layers of agent control mechanisms:
Immediate Kill Switch: Complete agent shutdown capability

- Clear communication of agent limitations to users
Backup System Integration: Alternative processing methods
- Rule-based systems for critical functions
- Legacy system reactivation procedures
- Data synchronization between primary and backup systems
Evidence Collection and Audit Trails
With the EU AI Act's emphasis on monitoring and evidence collection, organizations must implement comprehensive logging:
