Investigation notes

CITGO Petroleum Corporation, a major energy company with significant operations, recently confirmed a data security incident affecting individuals in Indiana. Filed with state regulators on August 26, 2026, this event involved unauthorized access to extensive personal records. The compromised data included Full Name, Social Security Number, Date of Birth, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, Home Address, and Phone Number.

Such a widespread exposure of foundational identifiers and financial details presents a serious threat. Individuals whose data was involved in the CITGO breach now face elevated risks of various frauds, including identity theft, unauthorized financial transactions, and tax return fraud. Attackers often use this type of comprehensive personal data to gain further access or execute sophisticated phishing schemes.

As an entity managing vast amounts of sensitive employee and partner data, CITGO Petroleum Corporation was obligated to uphold robust data protection standards. State laws and common-law duties mandate the implementation of strong administrative and technical safeguards to prevent unauthorized access. The occurrence of this data breach raises questions regarding the adequacy of CITGO's security measures and whether these legal duties were fully met to protect sensitive information from foreseeable cyber threats. Our investigation seeks to understand the circumstances that led to this incident.

If you received a data breach notification letter from CITGO Petroleum Corporation, it signifies that your private information was compromised.

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 Indiana.

Did CITGO Petroleum Corporation offer free credit monitoring?
Any free monitoring CITGO Petroleum Corporation is offering will be described in the notice you received, along with an activation code and a sign-up deadline.
