What happened
On January 20, 2026, Lamb-Star Engineering, LLC ("Lamb-Star"), a civil engineering firm headquartered at 3801 Parkwood Boulevard, Suite 550 in Frisco, Texas, detected suspicious activity on its network. According to the company's notice, Lamb-Star disconnected the affected systems and remote access the same day and engaged third-party cybersecurity and information-technology specialists to launch a forensic investigation.
The forensic investigation concluded on March 4, 2026 and confirmed that an unauthorized actor had accessed the network on January 20, 2026. A review of the compromised files and the list of affected individuals was finalized on April 29, 2026. Written consumer notices were mailed on May 11, 2026, approximately 3.7 months after the suspicious activity was first detected, to 415 Texas residents, and the incident was reported to regulators in Texas and Maine. The notice states that the data accessed without authorization varied by individual and can include name, Social Security number, date of birth, driver's license or state identification number, government-issued identification number such as passport number, financial account or credit or debit card number, health insurance information, and other personal details contained in Lamb-Star records. Lamb-Star is offering complimentary identity monitoring and fully managed identity-theft recovery services through Kroll, although the duration of the monitoring was not specified in the public notice.
Because Social Security numbers, driver's license numbers, passport numbers, financial account and payment card details, and health insurance information were among the data elements reportedly involved, the categories of data at issue in this incident raise heightened concerns about identity theft, financial fraud, and tax-refund fraud. Whether Lamb-Star's pre-breach security practices met legal standards under applicable state and federal laws, and whether the multi-month notification delay caused additional harm to affected individuals, are among the issues being evaluated.
What to do if you received a letter
Keep your notice letter
Do not discard it. Your letter contains the enrollment code for the free Kroll identity monitoring and identity-theft recovery services and is important evidence if you decide to participate in a lawsuit.
Enroll in the free Kroll identity monitoring
Enroll in the complimentary identity monitoring and fully managed identity-theft recovery services through Kroll using the instructions and enrollment code included in your notice. Accepting these benefits does not waive your right to pursue legal action.
Place a fraud alert or credit freeze
Contact Equifax, Experian, and TransUnion to place a fraud alert or freeze on your file. Request a free weekly credit report from AnnualCreditReport.com, and use the FTC's IdentityTheft.gov recovery guide.
Because Social Security numbers, driver's license numbers, passport numbers, financial account and payment card details, and health insurance information were among the data elements reportedly involved, consider placing a fraud alert or security freeze on your credit file with each of the three major credit bureaus, requesting an Identity Protection PIN (IP PIN) from the IRS to guard against tax-refund fraud, monitoring your bank, credit card, and explanation-of-benefits statements for unfamiliar activity, and notifying your state's department of motor vehicles and the U.S. Department of State about the potential misuse of your driver's license or passport number.

I received a data breach letter from Lamb-Star Engineering. What should I do? +
Keep the letter, enroll in the complimentary Kroll identity monitoring and fully managed identity-theft recovery services using the enrollment code in your notice, review your bank, credit card, and health-insurance explanation-of-benefits statements for unfamiliar activity, request your credit reports and place a fraud alert or security freeze with the three major credit bureaus if necessary, consider requesting an IRS Identity Protection PIN given the exposure of Social Security numbers, and contact a data breach attorney for a free consultation. Accepting the Kroll services does not waive your right to sue.

If you were among the 415 individuals who received a May 11, 2026 breach notice from Lamb-Star Engineering, you are likely eligible for a free case evaluation.
