Opportune LLP, a global energy consulting firm that provides strategic, financial, and operational expertise, officially reported a data breach to Indiana regulators on September 17, 2026. The breach originated from a security incident that occurred on June 22, 2026. The company handles various sensitive records, including personnel and financial data.

The breach involved the exposure of several categories of sensitive personal information. The data types identified as compromised include Full Name, Social Security Number, Date of Birth, Mailing Address, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, and Employee Identification Number. The specific technical nature of the breach, such as whether it involved unauthorized network intrusion or a third-party vendor compromise, was not detailed in the public filings.

The exposure of such a comprehensive set of personal identifiers and financial details carries considerable risks for affected individuals. Compromised Social Security Numbers and Dates of Birth can be leveraged for identity theft, leading to fraudulent accounts or loans. Furthermore, the exposure of Direct Deposit Account Details, Wage and Compensation Information, and Tax Return Information heightens the potential for financial fraud, unauthorized transactions, or fraudulent tax filings.

Individuals who receive a data breach notification from Opportune LLP should take proactive steps to protect their information. It is advisable to closely monitor all financial account statements and credit reports for any suspicious or unauthorized activity. Placing a fraud alert or security freeze on credit files with the major credit bureaus can help prevent new accounts from being opened in one's name. Additionally, be vigilant about unsolicited communications that request personal or financial details.

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.
