Opportune LLP Data Breach Exposes Sensitive Financial and Personal Data of Over 32,000 Texas Residents
A significant data breach at Opportune LLP, a Houston-based business advisory and consulting firm serving the oil and gas industry, has compromised the personal and financial information of thousands of individuals. The breach, which occurred on or around June 22, 2026, was discovered on August 18, 2026, and disclosed in September 2026 through notification letters mailed to affected parties.
Opportune LLP, which processes royalty payments for Phillips 66, exposed sensitive data belonging to individuals who receive or previously received royalty payments. While Phillips 66’s systems were not breached, the incident impacted over 32,000 Texas residents, along with 322 Massachusetts and 56 Vermont residents, with additional potential victims nationwide.
Exposed data includes:
- Full names
- Social Security numbers
- Financial account and credit/debit card details
The breach poses severe risks, including identity theft, fraudulent account creation, tax fraud, and targeted phishing attacks, due to the sensitivity of the compromised information.
Edelson Lechtzin LLP, a national class action law firm, is investigating potential legal claims against Opportune LLP, assessing whether the firm failed to implement adequate cybersecurity measures. The firm is offering free case evaluations to affected individuals to explore their rights and potential remedies.
Opportune LLP has partnered with Cyberscout to provide complimentary credit monitoring to impacted individuals, though the breach’s long-term implications remain a concern for those exposed.
