Halliburton, one of the world’s largest energy companies, has confirmed that it was the victim of a cyberattack. Hackers infiltrated the company’s systems and stole sensitive information. The attack occurred last week, and Halliburton is still determining the extent of the data that was taken.
In a recent filing with government regulators, Halliburton acknowledged the breach but has yet to disclose the full details of what was stolen. The company is currently investigating the incident and deciding what legal notifications are required. In response to the attack, Halliburton took certain systems offline as a precaution and is working to restore normal operations, especially for its oil and fracking businesses.
When approached for additional comments, company spokesperson Amina Rivera declined to elaborate further, stating that Halliburton would not provide more information beyond what was mentioned in its official filing.
Although Halliburton has not officially confirmed it, there are signs that the cyberattack may have been part of a ransomware campaign. TechCrunch obtained a ransom note related to the incident, which claims that hackers encrypted Halliburton’s files and stole sensitive data. A group known as RansomHub is believed to be behind the attack. This gang is notorious for carrying out similar cyberattacks, using stolen data as leverage to demand ransom payments.
RansomHub typically publishes stolen files on its dark web platform when victims refuse to pay. So far, Halliburton has not been listed as one of RansomHub’s victims, but this could change if negotiations fail. RansomHub has been responsible for over 210 attacks since its rise to prominence earlier this year, and it has targeted other large organisations, including Change Healthcare.
Halliburton, with around 48,000 employees spread across various countries, is a major player in the global energy industry. In the past, the company gained notoriety due to its role in the Deepwater Horizon oil spill disaster in 2010, for which it paid over $1 billion in fines.
The recent cyberattack is expected to have financial repercussions for the company, though the exact costs are yet to be determined. In 2023, Halliburton reported $23 billion in revenue, with CEO Jeff Miller earning $19 million in total compensation. Halliburton has noted that it will continue to bear costs related to the cyberattack as they work on restoring systems and resolving the situation.
As the investigation unfolds, much of Halliburton’s online services remain down, and the company is assessing the full impact of the breach. Halliburton has been tight-lipped about its cybersecurity efforts, declining to provide information on who is currently overseeing their response.
This attack is a reminder of how large corporations remain vulnerable to cyber threats. Halliburton's situation underscores the importance of investing in strong cybersecurity measures to safeguard sensitive data and avoid disruptions in critical operations. The company will likely provide more updates as it works to recover from this breach.
