What we know

CITGO Petroleum Corporation, a major energy company, experienced a data security incident that it reported to the Texas Attorney General in September 2026. The breach, which occurred on November 13, 2025, involved unauthorized access to systems containing personal information belonging to individuals associated with the company. The investigation into the incident is ongoing, with CITGO monitoring the situation.

The compromised data types identified in the filing include Full Name, Social Security Number, Date of Birth, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, Mailing Address, and Telephone Number. This combination of data is highly sensitive and can be leveraged by malicious actors for various fraudulent activities. It's critical for affected individuals to understand the potential risks.

The exposure of a Social Security Number and Date of Birth can form the foundation for identity theft, allowing criminals to open new lines of credit, make unauthorized purchases, or file fraudulent tax returns in your name. When combined with Wage and Compensation Information or Tax Return Information, the risk escalates significantly, potentially enabling more sophisticated financial fraud schemes. Additionally, Direct Deposit Account Details could expose victims to direct financial losses through unauthorized transactions or account takeovers.

If you have received a notification letter from CITGO Petroleum Corporation, it is important to carefully review its contents for specific details about the information exposed. Consider immediately placing a fraud alert or security freeze on your credit reports with the three major credit bureaus (Equifax, Experian, and TransUnion). Regularly monitor your financial accounts and credit reports for any suspicious activity or unauthorized transactions.

Companies like CITGO have a legal obligation to protect the personal data they collect and store. A breach of this nature suggests that security measures may have been insufficient to prevent unauthorized access. If your data was compromised in this incident, you may be entitled to legal recourse. We are currently offering a free, no-obligation case review to help affected individuals understand their rights and potential options.
