Sept 3 (Reuters) - U.S. oilfield services firm

Halliburton ( HAL ) 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 ( HAL ) systems, caused

disruptions and limited access to portions of its business

applications, the Houston-based company said.

Halliburton ( HAL ) added it believed that the incident did not

have and is not reasonably likely to have a material impact on

its results.

The company did not specify the expenses incurred. It did

not immediately respond to 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.
