MathWorks, Inc. Data Breach — Class Action Review

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.
