What happened
The Gilman Brothers Company ("Gilman Brothers"), a Connecticut-based foamboard manufacturer founded in 1897, detected and investigated a security incident involving its computer systems. According to the notice filed with the Massachusetts Attorney General, certain files containing personal information were accessed. The company states it found no evidence of actual or attempted misuse but chose to notify potentially affected individuals and regulators.
Gilman Brothers began mailing notification letters on or around June 25, 2026 and reported the incident to the Massachusetts Attorney General on June 26, 2026. The filing indicates that Social Security numbers were present in the affected files. The company is offering 24 months of complimentary Experian IdentityWorks credit monitoring and identity-restoration services. The Massachusetts filing lists 5 affected individuals.
Because Social Security numbers are among the most sensitive categories of personal information, exposure can carry a long-term risk of identity theft and financial fraud. Whether the company's pre-breach security practices met legal standards is among the issues being evaluated.
