AI Incident Response: When Sensitive Data Reaches the LLM

The alert fires: an employee just uploaded a spreadsheet containing 10,000 customer Social Security Numbers to ChatGPT. What do you do?

Immediate Response (First Hour)

1. **Confirm the incident**: Verify what data was exposed and to which AI service

2. **Preserve evidence**: Screenshot logs, export audit trails

3. **Assess scope**: How many records? What data types? Which service?

4. **Notify stakeholders**: Legal, privacy, communications as appropriate

Short-Term Actions (24-72 Hours)

1. **Contact the AI provider**: Request data deletion confirmation

2. **Determine notification requirements**: GDPR (72 hours), state laws vary

3. **Prepare communication**: Internal and potentially external

4. **Implement immediate controls**: Prevent recurrence

Documentation Requirements

For every AI data incident, document:

• Timeline of events
• Data types and volume affected
• Root cause analysis
• Remediation actions taken
• Preventive measures implemented

Regulatory Considerations

• **GDPR**: 72-hour notification to supervisory authority if risk to individuals
• **HIPAA**: Breach notification within 60 days if PHI involved
• **State Laws**: Vary by jurisdiction, some as short as 30 days

Lessons Learned

Every AI data incident should result in:

• Updated policies if gaps identified
• Additional technical controls if bypassed
• Training updates if user behavior was factor
• Tabletop exercises to test improved response

The goal isn't just to respond to this incident—it's to prevent the next one.
