Helix Energy Solutions Group Hit by CL0P Ransomware Attack, Exposing Sensitive Data of Thousands
Helix Energy Solutions Group, Inc., a Houston-based offshore energy services provider, suffered a significant data breach following a ransomware attack by the CL0P cybercriminal group. The incident, first reported to the Texas Attorney General on May 5, 2026, involved unauthorized access to sensitive personal information of at least 4,661 individuals in Texas.
The breach originated on November 13, 2025, when CL0P claimed responsibility and posted details on the dark web. Exposed data included names, addresses, Social Security numbers, driver’s license numbers, government-issued IDs, and dates of birth leaving affected individuals vulnerable to identity theft and fraud.
Helix Energy Solutions Group notified impacted parties via U.S. mail. The company specializes in offshore well intervention, robotics, and decommissioning services, serving the global energy sector.
Legal firm Shamis & Gentile P.A. is investigating potential compensation for those affected, citing damages such as lost time, financial losses, and heightened identity theft risks. The breach underscores the ongoing threat of ransomware attacks targeting critical infrastructure and corporate data.
