Halliburton experiences cyberattack at campus in Houston, Texas

(WO) – Halliburton, a major U.S. oil field services firm, experienced a cyberattack on Wednesday, affecting some of its systems, particularly at its north Houston campus and global connectivity networks, Reuters reported.

Citing an emailed press release and unnamed sources close to the matter, Reuters says Halliburton is investigating the incident and working with external experts to resolve it. Some employees have been asked not to connect to internal networks.

Although details about the Halliburton attack are unclear, ransomware typically involves hackers encrypting data and demanding payment in exchange for a decryption key. If the ransom is not paid, hackers may threaten to leak sensitive information.

Halliburton provides drilling equipment and services to major oil and gas companies around the world. With nearly 50,000 employees globally, the company has a presence in over 70 countries.
