Background

What happened in the Opportune data breach

Opportune LP, a wholly owned subsidiary of Opportune, describes itself as a vendor and service provider in the oil & gas industry that works with many companies in the industry to provide accounting services, facilitate payments, and other services. According to its notice letter, Opportune learned that an unauthorized actor gained access to its network environment, and the impacted systems were initially accessed on or about June 22, 2026. The Texas filing gives July 1, 2026 as the end date of the breach.

In a filing with the New Hampshire Attorney General, Opportune states that on September 22, 2026 it discovered that the impacted systems contained additional personal information, and that it is providing written notification to affected residents commencing on or about October 22, 2026. That filing is a supplemental notice to one provided on September 18, 2026, and the Indiana Attorney General lists notices sent September 17, 2026. The New Hampshire filing states the information impacted included individuals' names, Social Security Numbers, bank account number, and routing number. The Texas filing lists Name of individual, Social Security Number Information and Financial Information, and the Vermont filing lists Social Security Numbers. The copy of the letter posted by the California Attorney General leaves the categories blank.

Opportune reported 107,071 affected individuals to the Texas Attorney General, including 38,068 Texans, and 128,106 affected individuals to the Indiana Attorney General, including 363 Indiana residents. The Vermont filing lists 86 Vermonters, and the New Hampshire filing covers an additional 10 New Hampshire residents. The letter offers complimentary Triple Bureau Credit Monitoring through Cyberscout, a TransUnion company, and the New Hampshire filing describes a one-year membership for residents whose Social Security numbers were impacted.

FAQ

Opportune data breach FAQ

I received a data breach letter from Opportune. What should I do? +

Keep the letter, enroll in the free Cyberscout Triple Bureau Credit Monitoring within the enrollment window stated in your letter, review your financial account statements and credit reports, consider a fraud alert or credit freeze, and contact a data breach attorney for a free consultation. Accepting credit monitoring does not waive your right to sue.

Is the Opportune data breach letter real or a scam? +

Opportune has reported this incident to the California, Indiana, New Hampshire, Texas and Vermont Attorneys General. Compare your letter to the official filing linked in Sources below, and use only the enrollment website and phone number printed in your letter. Be cautious of unexpected calls, texts or emails about the breach that ask for your Social Security number or account login. If you are unsure, send your letter to Dapeer Law for a free review.

Why did I get an Opportune letter if I never used Opportune? +

Opportune's letter says it works with many companies in the oil & gas industry to provide accounting services, facilitate payments, and other services, and that it received your information in the course of providing services to a company named in your letter. The copy posted by the California Attorney General leaves that company's name blank; your own letter should name it.

Am I eligible to join a class action against Opportune? +

If you received a breach notice letter from Opportune about this incident, you are likely eligible for a free case evaluation. Eligibility depends on your state of residence, the categories of your data that were involved, and any losses you have suffered. Dapeer Law will review your notice at no cost.

How much money could I receive from a class action lawsuit? +

Data breach class action recoveries vary significantly. Settlements typically range from a few hundred dollars for basic out-of-pocket losses to several thousand dollars for documented identity theft, with class size, damages, and negotiation all affecting the final amount. No payout is guaranteed, and this investigation has not yet resulted in a settlement.
