Investigation notes

On September 25, 2026, CITGO Petroleum Corporation formally disclosed a data security incident to the Office of the Texas Attorney General. This report confirms that unauthorized access occurred on or around November 13, 2025, affecting the personal data of individuals. As a major energy sector enterprise, CITGO handles extensive personal information, and this breach signals a serious compromise of its data protection infrastructure.

The confirmed exposed data categories 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. The unauthorized access to such a comprehensive set of personal identifiers and financial details creates substantial risks. Individuals whose data was compromised face an increased likelihood of identity theft, financial fraud, and other forms of personal and economic harm.

Under Texas state law, CITGO Petroleum Corporation had a clear legal obligation to implement and maintain reasonable and appropriate cybersecurity measures to protect this sensitive data. The occurrence of a data breach of this nature suggests that the existing safeguards may have been insufficient to prevent sophisticated cyber threats. Our firm is examining whether CITGO met its duty of care in securing the personal information entrusted to it.

Receiving a notification letter from CITGO is a formal acknowledgment that your confidential information was compromised. This establishes your legal standing to explore potential claims. Many data privacy frameworks recognize that the increased, imminent risk of future harm is sufficient grounds for legal action, even if no actual theft has occurred yet. Understanding your rights and options in this situation is important.

This incident underscores the ongoing cybersecurity challenges faced by large corporations, particularly those in critical infrastructure sectors. For those affected by the CITGO Petroleum Corporation data breach, pursuing legal action through a class action framework can not only seek redress for individuals but also encourage companies to strengthen their data security practices. We offer free case evaluations to help affected individuals understand their legal position and potential next steps.

What our attorneys examine

A cyberattack does not excuse a company from protecting the information it holds. We look at whether CITGO Petroleum Corporation used reasonable security, how long it kept the data, and how quickly it told the people affected. Those questions decide whether a class action or individual claim is possible. Read more on how ransomware lawsuits work, or browse other incident files in Texas.

CITGO Petroleum Corporation data breach questions

How many people were affected by the CITGO Petroleum Corporation data breach, and what was exposed?
The filing does not give a count of affected people and lists the following information as involved: Full Name, Social Security Number, Date of Birth, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, Mailing Address, Telephone Number. Your own letter is the best guide to what was exposed about you, since notices are usually tailored to each person.
Is the CITGO Petroleum Corporation data breach letter legit or a scam?
A notice from CITGO Petroleum Corporation in the mail matches the breach CITGO Petroleum Corporation reported to the Texas Attorney General on September 25, 2026. Check that the company name and dates in your letter match that filing. A real notice of data security incident won't ask for your password, Social Security number or a payment — if it does, contact CITGO Petroleum Corporation through a phone number or website you find yourself.
Did CITGO Petroleum Corporation offer free credit monitoring?
Check your letter from CITGO Petroleum Corporation. If free credit or identity monitoring is offered, the enrollment code and deadline are printed in the notice itself. Because Social Security numbers are listed in this filing, identity monitoring and a credit freeze matter more than usual. Using the free service won't stop you from joining a lawsuit or settlement later.
Is there a CITGO Petroleum Corporation data breach class action lawsuit?
Law firms often open an investigation after a breach notice like this one, and a class action lawsuit may follow.

You usually don't have to join a class action to be included — if a settlement is reached, class members are notified and can file a claim.
What should I do after getting the CITGO Petroleum Corporation data breach notice?
Keep the letter and the envelope, and note the date it arrived. Freeze your credit with Equifax, Experian and TransUnion, change any passwords the notice mentions, and sign up for any free credit monitoring the letter offers. Then check whether you may have a claim.

Can I sue CITGO Petroleum Corporation over the data breach?

How much could a CITGO Petroleum Corporation data breach settlement or claim be worth?
