Halliburton has confirmed that it experienced a cyberattack in August, resulting in unauthorized access to its systems and the exfiltration of data. In its filings, the company reported that the attack caused disruptions to business applications but is unlikely to have a material financial impact. Halliburton activated its cybersecurity response plan and is actively investigating the incident, with external advisors assisting in the process. Some of its public-facing systems remain offline as the company assesses the scope and nature of the stolen information. The incident has raised concerns within the energy sector, which has faced increasing cyber threats in recent years, including ransomware attacks. Halliburton has not confirmed whether it has been contacted by the hackers, believed to be linked to a group called RansomHub.
