What happened
On May 8, 2026, Wilmer Cutler Pickering Hale and Dorr LLP (WilmerHale) experienced a data security incident in which an employee inadvertently provided personal information to an individual who falsely claimed to be authorized to receive it. According to the notice filed with the California Attorney General, the information had been collected in the course of the firm providing legal services.
WilmerHale reports that it began an investigation immediately, engaged outside forensic specialists, and notified federal law-enforcement authorities. The firm states the event was isolated and that the third party did not directly access WilmerHale's internal systems. WilmerHale completed its review and mailed notice letters to affected individuals on July 10, 2026, roughly two months after the incident, and is offering 24 months of complimentary Experian credit monitoring and identity-theft protection.
The notice indicates the information involved may have included full names and Social Security numbers. Because a Social Security number cannot be changed and can be used to open fraudulent accounts or file false tax returns, individuals whose information was disclosed may face an ongoing risk of identity theft. State filings identify 478 affected individuals in total, including 436 Texas residents and 42 Massachusetts residents, with California residents also included in the total.

Common questions
I received a data breach letter from WilmerHale. What should I do? +
Keep your July 10, 2026 notice letter. Enroll in the complimentary 24-month Experian credit monitoring using the code in your letter, consider placing a fraud alert or a credit freeze with the three major credit bureaus, and monitor your financial accounts and tax filings closely. Because Social Security numbers were involved, watch for signs of new-account fraud. You may also wish to speak with a data breach attorney about your options.
Am I eligible to join a class action against WilmerHale? +
Individuals who received a breach notice from WilmerHale are the most likely to qualify.
