Understanding your Metropolitan Marine Maintenance Contractors' Association ("MMMCA") data breach notification letter
If a Metropolitan Marine Maintenance Contractors' Association ("MMMCA") letter arrived in your mailbox, here is what it means, why you received it, and the free steps you can take right now.
Why you received this letter
Metropolitan Marine Maintenance Contractors' Association (MMMCA) appears to be a professional trade association or industrial services organization focused on coordinating maritime maintenance and infrastructure support. As an entity managing contractor relations and workforce logistics, the organization typically collects and stores sensitive personal information, including employee and contractor Social Security numbers, payroll records, tax documentation, and detailed contact information. This data breach was officially reported to the Maine Attorney General in 2026, confirming that unauthorized parties may have accessed internal systems containing such records. If you have received a formal data breach notification letter from MMMCA, it indicates that your personal information was likely stored within their systems at the time of the incident and may have been compromised.
