- Conduct comprehensive email security audit
- Implement corrective controls
- Conduct staff retraining on phishing
- Document all incident response actions
60+ Days and Ongoing
- Submit OCR notification if required
- Implement email security improvements
- Deploy multi-factor authentication
- Conduct regular phishing simulations
- Monitor for follow-up phishing attempts
- Provide ongoing security awareness training
- Review and update email security policies
Phishing Email Analysis
Conduct thorough analysis of the phishing attack:
- Email headers: Analyze sender IP, routing, and authentication results (SPF, DKIM, DMARC)
- Message content: Identify the target (specific departments, job roles, or healthcare systems)
- Links: Document URLs and whether they match legitimate services
- Attachments: Scan for malware if present
- Social engineering: Identify tactics used (urgency, authority, fear)
- Technical sophistication: Assess if this is targeted or mass phishing
- Targeted data: Determine what information was being harvested
Credential Reset Procedures
If credentials were compromised:
- Force immediate password change for affected users
- Require complex passwords (at least 12 characters, mixed case)
- Enable multi-factor authentication if not already active
- Review active sessions and terminate unauthorized ones
- Reset API keys or access tokens for automated systems
- Monitor for password reuse across systems
- Notify users to change passwords on personal accounts if they used similar ones
System Access Review
Thoroughly review system logs for compromise:
- EHR access logs: Check for unusual access patterns or data downloads
- Email access: Review login locations, device information, and forwarding rules
- VPN/remote access: Check for unusual connection patterns
- File shares: Look for unusual file access or downloads
- Admin activity: Check for any account privilege escalation
- Data exfiltration: Look for unusual network traffic or large data transfers
- Forensic analysis: If serious compromise suspected, consider engaging forensics firm
Breach Assessment and Notification
If patient data was accessed:
- Determine which patients' records were accessed
- Assess the type of information accessed
- Notify affected patients within 60 days
- Provide breach notification details
- Offer credit monitoring if financial information was exposed
- File OCR breach report if required
- Report to media if 500+ patients affected
Prevention and Mitigation
Email security controls:
- Implement advanced email filtering and phishing detection
- Deploy email authentication (SPF, DKIM, DMARC)
- Implement banner warnings for external emails
- Use email sandboxing for suspicious attachments
- Block known phishing URLs at gateway
- Disable legacy email protocols (POP3, IMAP)
User training and culture:
- Conduct regular security awareness training (quarterly minimum)
- Deploy simulated phishing campaigns to identify vulnerable users
- Create a safe reporting mechanism for phishing attempts
- Recognize and reward staff who report phishing
- Include phishing response in onboarding training
Frequently Asked Questions
Is a phishing attack automatically a breach?
Not necessarily. If the recipient did not click the link or enter credentials, and no data was accessed, it may not be a breach. However, you must investigate whether credentials were compromised and if unauthorized access to patient data occurred. When in doubt, conduct a thorough assessment.
What should I do if someone clicked a phishing link?
Immediately reset their credentials and check for unauthorized access. Review system logs to see if any patient data was accessed using their account. Monitor their account for suspicious activity. Provide additional training on phishing recognition.
Do I need to report phishing to law enforcement?
You may report phishing attacks to IC3.gov (Internet Crime Complaint Center). If patient data was compromised, you must report to HHS OCR as a breach. Law enforcement coordination is recommended for advanced or targeted phishing attacks.
How can I prevent phishing attacks?
Implement email security tools, conduct staff training, deploy multi-factor authentication, and create a culture of reporting suspicious emails. Regular security awareness training is the most effective prevention method. Simulated phishing campaigns help identify vulnerable employees for additional training.
