What happened
According to a notice filed with the Massachusetts Attorney General, Port Harbor Marine, a Maine marine sales and services company headquartered in South Portland, detected unusual activity on its network on February 18, 2026. The company says it immediately began containment measures and engaged third-party computer forensic specialists. The investigation determined that an unauthorized actor had access to certain systems between January 27 and February 18, 2026, and the company notified federal law enforcement.
Port Harbor Marine completed its review of the affected files on June 29, 2026 and began mailing notification letters on July 14, 2026, nearly five months after the incident was discovered. The company reported the incident to the Massachusetts Attorney General on July 17, 2026, stating that 196 Massachusetts residents were affected. According to the notice, the information involved may include first and last name, Social Security number, driver's license number, financial account information, credit and debit card numbers, and medical information. The company is offering 24 months of single-bureau credit monitoring through Cyberscout, a TransUnion company.
Because Social Security numbers, financial account and payment card details, and medical information were reported to be among the data involved, notice recipients may face an elevated risk of identity theft, financial fraud, and medical identity theft. Whether the company's data security practices met legal standards, and whether the notification delay caused additional harm, are among the issues Dapeer Law is evaluating.
