Halliburton says expenses incurred in response to August cyber attack

US oilfield services firm Halliburton said on Tuesday it has incurred and is likely to continue to incur expenses related to its response to a cyber attack in August.

The incident, in which an unauthorised third party accessed and removed information from Halliburton's systems, caused disruptions and limited access to portions of its business applications, the Houston-based company said.

Halliburton added it believed that the incident did not have and is not reasonably likely to have a material impact on its results.


The company declined to comment on Reuters' requests for additional information on the nature of data removed and expenses incurred.

However, the company activated its cybersecurity response plan and launched an investigation internally with the support of external advisors to assess and remediate the unauthorized activity once it became aware of the issue, it said.
