How to Protect Yourself

If you believe you may have been affected by this breach, take these protective steps:

Monitor Medical Records: Regularly review your medical records and insurance statements for unfamiliar services, treatments, or providers.

Check Credit Reports: Obtain free credit reports from all three major credit bureaus and look for suspicious accounts or inquiries.

Enable Credit Monitoring: Consider enrolling in credit monitoring services, especially if offered by The City of Long Beach as part of breach response.

Review Insurance Statements: Carefully examine health insurance explanation of benefits (EOB) statements for unauthorized medical services.

Report Suspicious Activity: Contact your healthcare providers, insurance companies, and credit bureaus immediately if you notice any fraudulent activity.

Secure Personal Information: Be cautious about sharing personal health information and verify the legitimacy of any healthcare-related communications you receive.

Update Passwords: Change passwords for any healthcare portals, insurance websites, or related online accounts.

Prevention Lessons for Healthcare Providers

This breach offers important lessons for healthcare organizations:

Network Segmentation: Isolate healthcare systems from other network components to limit breach scope and impact.

Regular Security Assessments: Conduct frequent vulnerability assessments and penetration testing to identify weaknesses before attackers do.

Employee Training: Implement comprehensive cybersecurity awareness training to help staff recognize and report potential threats.

Incident Response Planning: Develop and regularly test incident response procedures to ensure rapid detection and containment of security incidents.

Access Controls: Implement strict access controls and regularly audit user permissions to ensure only authorized personnel can access PHI.

Encryption: Encrypt sensitive data both in transit and at rest to make stolen information less valuable to attackers.

Vendor Management: Carefully vet and monitor third-party vendors who have access to healthcare systems or data.

Backup and Recovery: Maintain secure, tested backups to enable rapid system recovery following cyberattacks.

Municipal healthcare providers face unique challenges, including limited budgets and complex governance structures that can complicate cybersecurity efforts. However, the scale of this breach demonstrates that even government healthcare entities are attractive targets for cybercriminals.

As healthcare organizations continue to face evolving cyber threats, investing in comprehensive security programs and HIPAA compliance measures becomes increasingly critical for protecting patient information and maintaining public trust.
