Halliburton shuts down systems after cyberattack

Halliburton disclosed that it detected unauthorized access to internal systems and proactively took some systems offline while investigating; the company provided limited details, and the Department of Energy said there were no indications the incident is affecting energy services. TechCrunch identified a potential single-sign-on (SSO) security issue that could allow access to internal systems, but Halliburton declined to comment on the nature of the incident or whether it has received communications from intruders.
