Data breach confirmed: Halliburton admits stolen data in August cyber attack
Halliburton Confirms Data Breach Following Cyberattack
Halliburton, one of the world's largest diversified energy services companies, has confirmed a data breach following a cyberattack in late August 2023. The company is currently evaluating the nature and scope of the stolen information and determining what type of notifications may be required.
The attack disrupted parts of Halliburton's operations, particularly at its Houston offices, although the full operational impact is yet to be fully outlined. With annual revenue of $23 billion in 2023 and 48,000 employees worldwide, the incident underscores the increasing targeting of critical energy infrastructure by cybercriminals.
In an SEC filing dated July 30, 2025, Halliburton revealed that it discovered the unauthorized access about a week earlier and immediately initiated an investigation with third-party cybersecurity experts and notified relevant authorities.
The company has incurred and will continue to incur expenses related to the attack. Halliburton, however, does not expect the attack to have a material impact on its financial condition or results of operations.
Federal authorities have warned about an ongoing threat to critical infrastructure providers, including the energy sector. The Department of Energy is working closely with interagency partners regarding the Halliburton cyberattack.
Halliburton remains subject to certain risks from the attack, including diversion of management's attention, pending litigation, changes in customer behavior, and regulatory scrutiny. The company has been in touch with customers and other stakeholders regarding the cyberattack and continues to offer its products and services across the globe.
A Halliburton spokesperson has no comment on the incident beyond the SEC filing. The ongoing investigation aims to clarify the precise types of information compromised and the full operational impact. The company is also working to pursue the responsible threat actors.
