Diamond Chemical Co LLC Data Breach

State
Indiana
Reported
May 5, 2026
Breach date
Jul 26, 2025

Diamond Chemical Co LLC, which operates in the specialized chemical manufacturing sector, formally reported a data security incident to the Indiana Attorney General on May 5, 2026. This breach, first identified in July 2025, involved an unauthorized intrusion into its systems.

The compromised data types include Full Name, Social Security Number, Date of Birth, Mailing Address, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, and Health Insurance Records. The exposure of sensitive information like Social Security Numbers, Dates of Birth, and Direct Deposit Account Details significantly increases the risk of identity theft, financial fraud, and unauthorized account access for affected individuals.

Companies like Diamond Chemical Co LLC have a legal obligation to protect the sensitive personal data they collect and store. The occurrence of a data breach suggests that the company may have failed to implement reasonable security measures, potentially leaving vulnerabilities in their digital infrastructure unaddressed.

If you received a data breach notification letter from Diamond Chemical Co LLC, it confirms that your private information was exposed. You do not need to have already experienced financial loss to consult an attorney; the increased risk of future identity theft alone can be sufficient for legal recourse.
