Records filed with the New Hampshire AG show that Horner & Shifrin, Inc. confirmed exposure of the information below:
The more sensitive the data involved, the stronger the potential claim. Disclosure of these categories is legally recognized harm.
Horner & Shifrin, Inc. operates as a prominent professional engineering, architecture, and design firm, providing comprehensive infrastructure planning, civil engineering, and construction oversight services for both municipal and private sector clients. Because of the complex nature of large-scale engineering and construction projects, the firm routinely collects, processes, and stores an extensive volume of highly sensitive data. This includes detailed personnel records, engineering blueprints, proprietary structural blueprints, financial accounting documents, subconsultant contracts, and comprehensive employee and client personally identifiable information necessary for payroll, benefits administration, and multi-million-dollar project execution.
In 2025, Horner & Shifrin, Inc. formally reported a significant data security incident to the New Hampshire Attorney General, indicating that unauthorized actors may have infiltrated their internal digital environment or third-party vendor platforms. In the architecture, engineering, and construction sector, data breaches often involve sophisticated ransomware attacks or unauthorized access to corporate networks where sprawling databases and project management files are stored. Because these firms frequently collaborate with government entities, utility providers, and private developers, their networks are prime targets for cybercriminals seeking intellectual property, corporate financial records, and deeply personal employee archives.
The exposure resulting from this incident involves critical categories of sensitive information, which may include individuals' full names, dates of birth, Social Security numbers, banking details, and payroll data. The compromise of Social Security numbers and financial details creates an immediate and severe risk of identity theft, fraudulent credit applications, and unauthorized banking transactions. Furthermore, when employee compensation and tax records are exposed, victims face prolonged vulnerability to tax fraud and synthetic identity creation, where bad actors utilize stolen credentials to open fraudulent accounts or intercept direct deposits.
Under state data security statutes, the Federal Trade Commission Act, and common law negligence principles, Horner & Shifrin, Inc. had an affirmative legal obligation to implement and maintain robust, industry-standard cybersecurity measures to protect private data from unauthorized disclosure. Safeguarding sensitive personnel and corporate files requires rigorous data encryption, multi-factor authentication, regular security audits, and prompt patching of known network vulnerabilities. The occurrence of a successful network intrusion strongly suggests that the company may have failed to maintain adequate security controls, leaving their digital infrastructure susceptible to malicious infiltration and violating the privacy rights of affected individuals.
Receiving an official data breach notification letter from Horner & Shifrin, Inc. serves as formal acknowledgment that your private information was compromised due to corporate security failures. Legally, this notification confirms your standing to participate in a class action lawsuit aimed at demanding accountability, securing compensation for your time and risk, and compelling the company to upgrade its security practices. Affected individuals do not need to prove that financial fraud has already occurred to seek legal recourse. Our firm handles these complex data privacy cases on a contingency fee basis, meaning you pay absolutely nothing out of pocket unless we successfully recover compensation on your behalf.
Many people wrongly assume a claim requires proven fraud. The law recognizes data exposure alone as harm. See which of these describes your situation:
You received a data breach notification letter from Horner & Shifrin, Inc.
You were a customer, patient, employee, or client of Horner & Shifrin, Inc.
Your personal information was stored in Horner & Shifrin, Inc.'s systems
Your Social Security number or driver's license number was exposed
Your financial account, credit card, or banking information was disclosed
You reside in the United States (all 50 states eligible)
That letter is legally required and confirms your data was exposed. It also gives you standing to file a claim.
What your notification letter means & what to do next →Act quickly to protect your identity and preserve your claim. Four steps, in order:
Keep the Horner & Shifrin, Inc. letter. It is the document that proves you were part of this breach; a claim without it is weaker. Store a scanned backup.
Your letter likely includes a monitoring activation code. Use it: free monitoring flags misuse of your data and records the harm for your case.
Freeze your credit with Equifax, Experian and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted whenever you need to apply for credit.
