Langabeer McKernan Burnett & Co.’s Data Breach Investigation

On August 15, 2025, LMB became aware of unauthorized access to its systems. Following the discovery of the breach, the company immediately took steps to isolate the affected systems and launched a comprehensive investigation. A specialized third-party cybersecurity firm was engaged to assess the scope of the breach.

The investigation confirmed that sensitive personal information and protected health information were accessed by an unauthorized third party. As a result, LMB reviewed the affected data to identify what information had been compromised and which individuals were impacted. On September 5, 2025, the company finalized the list of individuals who were affected and began mailing breach notification letters.

While no specific evidence of misuse of the exposed data has been found, the breach has potentially impacted a wide range of sensitive information, including financial details and health insurance data. LMB has since taken additional security measures to prevent further unauthorized access.

When Did This Breach Occur?

LMB became aware of the breach on August 15, 2025, when unauthorized access to its systems was detected. The company’s investigation confirmed that the breach occurred during that time, and the affected data was reviewed and confirmed by September 5, 2025.

What Information Was Breached?

The breach potentially exposed the following sensitive personal and protected health information:

• Name
• Social Security number
• Driver’s license or state ID number
• Financial account information
• Health insurance information

This type of personal information is critical and can be used maliciously, potentially leading to identity theft, financial fraud, or misuse of health-related data.

What You Can Do

If you were affected by the LMB data breach, it’s important to take immediate steps to protect your personal information:

1. Enroll in Complimentary Credit Monitoring: LMB is offering affected individuals complimentary credit monitoring services through TransUnion. These services include a credit report, credit score, and alerts for any changes to your credit file. The service lasts for 12 months, but you must follow the activation instructions provided.
2. Monitor Your Financial Accounts: Keep a close watch on your bank accounts, credit card statements, and other financial records for any unusual activity or unauthorized transactions.
3. Place a Fraud Alert or Credit Freeze: Consider placing a fraud alert or a credit freeze on your credit file with the three major credit bureaus (Experian, TransUnion, and Equifax). This will help prevent anyone from opening new accounts in your name without your consent.
4. Review Your Data Breach Notification Letter: Carefully read the notification letter sent by LMB. It will provide you with specific details about the breach and instructions on how to protect yourself, including enrolling in credit monitoring services.
5. Consult with a Lawyer: If you have been impacted, you may be entitled to compensation. Consider speaking with an attorney who specializes in data breach lawsuits to explore your legal options.
