Data breach at Halliburton confirmed in August cyber attack
Halliburton Suffers Ransomware Attack, Remains Operationally Stable
Halliburton, one of the world's largest diversified energy services companies, experienced a ransomware attack by the RansomHub gang in August 2024. The incident, disclosed publicly in mid-2025, compromised the company's data, but specific operational or financial impacts have not been detailed publicly.
Despite the breach, Halliburton reported strong financial results for Q2 2025, with net income of $472 million and revenue of $5.5 billion, indicating resilience or rapid recovery from the attack.
The energy services sector is not immune to such cyberattacks, and incidents like these can have far-reaching consequences. They can potentially disrupt global energy supply chains and operations, leading to operational downtime, loss of intellectual property, and increased costs for cybersecurity and insurance. These disruptions can affect the broader industry’s stability and trust.
The attack on Halliburton highlights critical vulnerabilities in the sector. Nation-state actors and hacktivists play distinct roles in such cyberattacks. Nation-state actors often have advanced capabilities and motivations tied to geopolitical interests, seeking strategic advantages by targeting critical infrastructure like energy firms. Hacktivists, on the other hand, may carry out attacks for ideological reasons, aiming to raise awareness or protest corporate or political practices.
Recent analyses show that nation-state hackers are increasingly using sophisticated techniques such as DNS evasion to infiltrate networks undetected. This evolving threat landscape requires energy companies to enhance defenses against both financially motivated ransomware gangs and politically motivated actors.
Federal authorities have warned about an ongoing threat to critical infrastructure providers, including energy, and Halliburton is working closely with interagency partners regarding the attack. The company is evaluating the nature and scope of the stolen information and is in touch with customers and other stakeholders in connection with the attack.
Halliburton discovered the cyberattack and immediately shut off certain services as a proactive measure. The company has incurred and will continue to incur expenses related to the cyberattack. However, the attack is not expected to have a material impact on Halliburton's financial condition or results of operations.
The company has not publicly linked the attack to a specific nation-state or hacktivist group, and attribution remains a complex and sensitive matter requiring further detailed investigation. Halliburton continues to offer its products and services across the globe.
In light of the attack, Halliburton is determining what type of notifications may be required due to the cyberattack. A Halliburton spokesperson has no comment on the incident beyond the SEC filing.

- The ransomware attack on Halliburton serves as a reminder that the cybersecurity of energy companies, including those in the finance sector, is a critical issue in today's technological era.
- As more advanced tactics like DNS evasion are employed by nation-state hackers, the energy industry needs to up their cybersecurity defenses to protect against both financially motivated groups and politically motivated actors.
- With increased cybersecurity threats, it's essential for companies like Halliburton, operating in diverse sectors like energy and technology, to remain proactive in their cybersecurity measures to safeguard their data, operations, and overall industry stability.
