The New Hampshire Attorney General's office lists a data breach report from MathWorks, Inc., filed August 22, 2025. Companies in this situation send legally required notification letters to affected individuals — if you found MathWorks, Inc.'s letter in your mail, this page explains what it means and what you can do.
The New Hampshire Attorney General filing confirms the breach notice — not a court case. Where no court record exists, no settlement figure or deadline is shown. Legal outcomes cannot be predicted or promised.
The official New Hampshire AG notice for MathWorks, Inc. identifies the following exposed data:
The more sensitive the data involved, the stronger the potential claim. Disclosure of these categories is legally recognized harm.
MathWorks, Inc. is a leading global developer of mathematical computing software, widely recognized for creating MATLAB and Simulink. Serving millions of engineers, scientists, researchers, and enterprise organizations across aerospace, automotive, financial services, and high-tech industries, the company maintains extensive digital infrastructure. Because of its core business model—providing advanced software development environments, engineering simulations, and collaborative tools—MathWorks routinely collects, processes, and stores vast amounts of sensitive corporate and personal data. This repository includes proprietary intellectual property, internal research data, system access credentials, and comprehensive records of its global workforce, clients, and software users.
In 2025, MathWorks, Inc. formally reported a significant cybersecurity incident to the New Hampshire Attorney General's office. While the full mechanics of the breach are still under active investigation, incidents affecting technology developers and enterprise software providers typically involve sophisticated network intrusions, unauthorized access to internal databases, or vulnerabilities within third-party vendor systems. Attackers frequently target tech companies to harvest credentials, intellectual property, and personally identifiable information stored within development environments, human resources systems, and customer relationship management platforms. When a breach of this nature occurs, it often points to critical lapses in network monitoring, delayed patch management, or insufficient access controls.
The data compromised in the MathWorks security incident exposes affected individuals to severe, long-term risks. Depending on the scope of the exposed systems, the breached files likely contain sensitive personal identifiers such as full names, dates of birth, Social Security numbers, employment records, and corporate or personal credential hashes. The exposure of Social Security numbers and birth dates creates an immediate and ongoing danger of identity theft and financial fraud, allowing malicious actors to open fraudulent credit lines, secure unauthorized loans, or intercept tax returns. Furthermore, the compromise of corporate email addresses, usernames, and password credentials opens the door to targeted phishing campaigns, credential-stuffing attacks, and subsequent unauthorized access to personal and professional accounts.
Under state and federal data protection standards, including the New Hampshire Regulation of Business Practices and Consumer Protection Act and applicable unfair and deceptive trade practices statutes, technology companies like MathWorks, Inc. have a strict legal duty to implement reasonable and appropriate administrative, physical, and technical safeguards to secure sensitive data. By collecting and retaining personal information, entities assume an implicit and legal obligation to maintain robust encryption, multi-factor authentication, and continuous threat detection. The occurrence of a widespread data breach strongly suggests a failure to uphold these standard security obligations, potentially exposing the company to liability for negligence and inadequate data protection.
Receiving an official data breach notification letter from MathWorks, Inc. is a formal acknowledgment that your private information was compromised due to corporate security failures. Legally, this notification establishes the necessary standing to participate in a class action lawsuit aimed at holding the company accountable for its security lapses. Affected individuals do not need to prove that they have already suffered actual financial loss to seek legal recourse; the increased and imminent risk of future identity theft is sufficient under the law. Our firm is investigating this breach on a contingency fee basis, meaning you pay no out-of-pocket costs and owe no legal fees unless we successfully recover compensation on your behalf.
Financial harm is not a requirement. The exposure of your personal information is itself recognized as actionable. Check the list — most letter recipients qualify under at least one item:
You received a data breach notification letter from MathWorks, Inc.
You were a customer, patient, employee, or client of MathWorks, Inc.
Your personal information was stored in MathWorks, Inc.'s systems
Your Social Security number or driver's license number was exposed
Your login credentials or passwords were exposed
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 →Four moves to make now — they protect both your identity and your legal position:
Your MathWorks, Inc. notification letter is legal evidence. Keep both physical and digital copies somewhere safe — it establishes you were affected and anchors your claim.
Look for the credit-monitoring offer section of your MathWorks, Inc. letter and enroll. It is free, and it creates a paper trail of any resulting fraud.
A no-cost freeze at each of the three bureaus (Equifax, Experian, TransUnion) blocks new-account fraud in your name; unfreeze anytime you apply for credit.
Time limits can forfeit your claim. Have attorneys review your MathWorks, Inc. case at no cost — contingency means zero upfront fees.

Compensation in a case like MathWorks, Inc.'s depends on where you live, what was exposed, and how the company responded. Common recovery categories:
Statutory damages exist independent of out-of-pocket loss — California's $100–$750 range is the model other states have followed.
Reimbursement for fraud charges, unauthorized transactions, or expenses you incurred as a direct result of the breach.
Time spent handling breach fallout — freezes, disputes, monitoring — is compensable.
Credit-monitoring subscriptions and protection plans you bought because of the breach are recoverable expenses.
SSN and driver's license exposure creates long-term identity theft risk. Courts recognize the ongoing value of this harm and may award damages accordingly.
New Hampshire's breach notification law (RSA 359-C) requires timely notice to affected individuals and the Attorney General. New Hampshire residents may pursue civil action for actual damages and attorney's fees stemming from inadequate data protection.
