How to protect against similar security incidents
In response to the ransomware attack on Mitchell County, North Carolina, affected individuals should take immediate steps to secure their personal and financial information.
- Monitor financial and medical records. Regularly review bank statements and Explanation of Benefits (EOB) documents for any unauthorized transactions or medical services you did not receive. Report any suspicious activity to your financial institution or healthcare provider immediately.
- Place a security freeze on credit files. Contact the three major credit bureaus—Equifax, Experian, and TransUnion—to place a security freeze on your credit reports. This prevents identity thieves from opening new accounts in your name without your explicit authorization.
- Update credentials and enable MFA. For individuals whose online account names and passwords were involved, change your passwords immediately across all platforms. Implement phishing-resistant multi-factor authentication (MFA) to provide an extra layer of security against unauthorized access.
- Implement continuous attack surface monitoring. Organizations should deploy attack surface management tools to identify and remediate vulnerabilities before they can be exploited. Ensure all software and systems are patched and that backup strategies are isolated from the primary network to defend against ransomware.
Proactive monitoring and the use of robust security controls are essential to defending against the long-term consequences of data exfiltration.
