A national law firm is turning up the heat on Minnesota Epilepsy Group after the practice warned patients that sensitive personal and medical records may have been exposed in a cybersecurity incident. The group’s notice says names, addresses, dates of birth, Social Security numbers, health insurance and treatment details could all be in the mix of potentially accessed files.
Wolf Haldenstein Adler Freeman & Herz LLP has launched an investigation and is urging anyone who received a breach letter to get in touch. The firm’s announcement lists a toll free line and an email contact ([email protected]) for potential claimants. It says the firm is looking into possible claims on behalf of those affected, according to GlobeNewswire.
Investigation Timeline and Scope
Minnesota Epilepsy Group reports it detected unauthorized access to its computer network on April 7, 2026. A forensic review later showed a third party had been inside parts of the network between March 16 and April 10. The practice says a subsequent review, completed May 18, identified files that contained personal information. It began mailing letters to affected individuals on June 5 and set up a confidential toll free inquiry line at 866-659-7085, according to ClassAction.org.
Earlier Disclosure on File
This is not Minnesota Epilepsy Group’s first run-in with a security incident. The practice previously disclosed a separate cybersecurity event discovered on Feb. 27, 2025, and warned at the time that clinical records such as EEG summaries, neuropsychology reports and medication records could have been affected. That earlier notice remains posted on the practice’s website and highlights just how sensitive the records it holds can be, per Minnesota Epilepsy Group.
What Patients Should Do
Minnesota Epilepsy Group says it has arranged complimentary identity theft protection for people whose Social Security numbers were involved. The practice is telling patients to keep a close eye on financial account statements and explanation of benefits forms. As a precaution, it recommends placing fraud alerts or security freezes and reporting any suspicious activity to law enforcement and the Federal Trade Commission. The mailed notice spells out these steps in more detail and includes the dedicated helpline for questions, according to ClassAction.org.
Legal Angle
With Wolf Haldenstein and other plaintiff firms now courting potential clients, legal trackers say attorneys are gathering contacts and weighing whether a class action makes sense. Several lawsuit notice and plaintiff intake sites are already hosting outreach pages and online forms for people who received breach letters, per ClassActionU and ClaimDepot.
Anyone who received a notification is urged to follow the instructions in the letter and can call Minnesota Epilepsy Group’s dedicated helpline at 866-659-7085 for more information. Those with questions about potential legal claims can also reach out to Wolf Haldenstein using the phone number and email listed in the firm’s release.
