Helix Energy Solutions Discloses Data Breach Impacting Thousands of Individuals
Helix Energy Solutions Group Inc., a Houston-based offshore energy services provider specializing in well intervention, robotics, and decommissioning for oil, gas, and renewable sectors, confirmed a data breach exposing sensitive personal information. The incident was first claimed by the CL0P ransomware group on November 13, 2025, via a post on the Tor network, asserting it had obtained company data.
The compromised data includes names, addresses, Social Security numbers, driver’s license numbers, government-issued IDs (passports, state IDs), and dates of birth. The breach affected 4,661 Texas residents, prompting Helix to report the incident to the Texas Attorney General.
Helix Energy Solutions has begun notifying impacted individuals via U.S. Mail, providing details about the breach and potential protective measures. The company serves clients across major offshore regions, though the full scope of the breach’s global impact remains unclear.
