CITGO Petroleum Corporation reported a data security incident to Indiana state officials on August 26, 2026. The company’s filing indicates the breach began on November 13, 2025, though the specific type of breach was not detailed in the public report.

The incident led to the compromise of various categories of personal information. The exposed 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.

Exposure of such detailed personal and financial records poses significant risks for affected individuals. Malicious actors could potentially exploit this information to commit identity theft, initiate fraudulent credit applications, conduct unauthorized banking transactions, or file false tax returns. Individuals should also be wary of targeted phishing scams.

As a large corporation handling extensive personal and professional data, CITGO Petroleum Corporation is responsible for maintaining robust security protocols. The occurrence of this breach suggests that the measures in place may not have been fully adequate to prevent unauthorized access to sensitive data. The company has stated its investigation into the incident is ongoing and monitoring the situation.

Individuals who received a notification from CITGO Petroleum Corporation are advised to monitor their financial accounts and credit reports closely for any unusual activity. Placing a fraud alert or credit freeze with major credit bureaus can help prevent new accounts from being opened in their name. Additionally, it is prudent to exercise caution with unsolicited requests for personal information, particularly those received via email or phone.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

  • Freeze your credit

    Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.

  • Guard against tax fraud

    File your tax return as early as possible and consider requesting an IRS Identity Protection PIN so no one can file a fraudulent return in your name.

  • Watch your financial accounts

    Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.

  • Stay alert to targeted scams

    Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.

  • Keep your notification letter

    Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
