Knowledge Research Center has reported a data security incident that compromised sensitive personal information belonging to individuals. The breach, which occurred in 2026, exposed data such as Full Name, Social Security Number, and Account Credentials, creating significant risks for those affected. Our firm is now investigating potential claims related to this incident.
DataBreachLawGroup.com has launched an investigation into the data breach reported by Knowledge Research Center. The research organization, which collects and maintains extensive sensitive information, formally reported a security incident to the California Attorney General on September 2, 2026. The incident itself occurred on or around July 8, 2026, compromising personal data entrusted to the institution.
The compromised dataset includes several critical categories of personal information. Individuals affected by this breach may have had their Full Name, Date of Birth, Social Security Number, Mailing Address, Email Address, Institutional Affiliation Records, Financial and Compensation Details, and Account Credentials exposed. This broad range of compromised data presents significant concerns for those involved.
The exposure of such deeply personal details, especially Social Security Numbers and Account Credentials, carries substantial risks. This information can be leveraged by malicious actors to commit identity theft, open fraudulent financial accounts, or conduct sophisticated phishing scams. Furthermore, the leakage of institutional and financial records can lead to further targeted fraud and other long-term personal security issues.
Knowledge Research Center, operating in California, is subject to strict data protection regulations that require maintaining reasonable security for the personal information it collects. The occurrence of this data breach suggests a potential failure to uphold these legal standards. Our firm is reviewing whether Knowledge Research Center adequately protected the data of its research subjects, partners, and participants.
