Mario Susi & Son, Inc. Data Breach Notice (Massachusetts Attorney General): What Was Exposed & What To Do

Data breaches involving personal identifiers continue to surface across industries in 2025 and 2026, often through notices filed with state attorneys general. These incidents underscore how even smaller organizations can become targets when they hold Social Security numbers, financial details, and government-issued IDs. The disclosure concerning Mario Susi & Son, Inc. fits this pattern: a formal notice to Massachusetts authorities that a limited number of residents had sensitive information exposed.

According to the filing reported on July 07, 2026, the company notified affected Massachusetts residents after discovering that Social Security numbers, financial account numbers, and driver’s license numbers were among the data involved. With 175 people listed as affected, the incident is modest in scale yet still carries lasting identity and financial risks for those individuals.

What happened

Mario Susi & Son, Inc. submitted a data-breach notice to the Massachusetts Office of Consumer Affairs, with the filing dated July 07, 2026. The notice, associated with the Massachusetts Attorney General’s reporting channel, states that the company informed Massachusetts residents of the incident. Public detail confirms that 175 people were affected and that the exposed information included Social Security numbers, financial account numbers, and driver’s license numbers. The precise date the intrusion or unauthorized access occurred, the technical method used, and any broader timeline remain undisclosed in the available summary. No additional counts, systems, or dollar figures have been released in the reported notice.

How a breach like this happens

Incidents that expose Social Security numbers, financial account data, and driver’s license numbers typically begin with an attacker gaining a foothold through common vectors such as phishing emails, compromised credentials, unpatched remote-access software, or misconfigured cloud storage. Once inside a network or application, the actor may locate databases, document repositories, or backup files that contain personal records. In many cases the data is copied rather than encrypted for ransom, then later used for fraud or sold. Organizations of any size can experience this sequence; the absence of a named threat group in the Mario Susi & Son, Inc. notice means the specific pathway remains unconfirmed and should not be assumed. Defensive measures that reduce likelihood include multi-factor authentication, timely patching, network segmentation, and continuous monitoring for unusual data access—practices that are standard recommendations rather than judgments about any single event.

Mario Susi & Son, Inc. and its sector

Mario Susi & Son, Inc. is a private company operating in Massachusetts. Businesses of this name and scale commonly work in construction, demolition, excavation, or related trade services—sectors that routinely collect and retain personal information from employees, subcontractors, and sometimes customers for payroll, insurance, licensing, and project documentation. Such firms typically maintain records containing government identifiers, bank or account details for payments, and driver’s license information for vehicle or site-access requirements. A breach at an organization in this sector is consequential because the data sets are dense with high-value identifiers that can be reused for identity theft long after the initial incident. Even when the absolute number of affected individuals is relatively small, the concentration of sensitive fields elevates the practical risk for each person named in the notice.

What data was at risk

The Massachusetts filing explicitly lists three categories of information as exposed: Social Security numbers, financial account numbers, and driver’s license numbers. These are the only data types confirmed in the public summary. Organizations in construction and related trades commonly also hold names, addresses, dates of birth, employment records, and insurance details, yet the notice does not confirm whether any of those additional elements were involved. Exact contents beyond the three named categories therefore remain unconfirmed. Readers should treat only the listed fields as established fact.

The real-world impact

For the 175 affected individuals, the combination of Social Security numbers, financial account numbers, and driver’s license numbers creates concrete opportunities for account takeover, new-account fraud, tax-refund fraud, and the creation of synthetic identities. Criminals can open credit lines, file false claims, or impersonate victims in government or banking interactions. Recovery often requires placing fraud alerts, freezing credit files, monitoring statements, and, in some cases, replacing driver’s licenses—steps that consume time and can produce lingering credit or administrative complications. For Mario Susi & Son, Inc. itself, the incident triggers notification obligations, potential regulatory scrutiny, and the operational cost of investigation and remediation. Because the notice is limited to Massachusetts residents and a defined headcount, the broader public impact is correspondingly bounded, yet each affected person still faces elevated personal risk until protective measures are in place.

Were you affected?

If you have a past or present relationship with Mario Susi & Son, Inc.—as an employee, contractor, or customer—and you live or have lived in Massachusetts, review any formal notice you may have received. Practical first steps include:

• Placing a free fraud alert or credit freeze with the three major credit bureaus.
• Monitoring bank, credit-card, and credit-report activity for unfamiliar inquiries or accounts.
• Changing passwords on financial and email accounts and enabling multi-factor authentication where available.
• Contacting your bank or card issuer promptly if you notice unauthorized transactions.
• Retaining the company’s notice and any reference numbers for future identity-theft reports.

You can also run a free exposure scan of your email address to check whether your information has already appeared in known breach data sets. Stay alert to unsolicited contacts that reference this incident; legitimate follow-up will not demand immediate payment or remote access to your devices.
