Powertech, a subsidiary of BC Hydro, says it experienced a cyber-attack on February 4.
The incident was detected promptly and the impact was contained, Powertech says.
A wholly owned subsidiary of BC Hydro, Powertech Labs supports electrical utilities, equipment manufacturers, and automotive industries.
“We have determined that some servers were encrypted and some data was copied to a cloud location. The exact type of data is still being determined.”
The cyber attack is being investigated and only a limited number of customers were affected, the company said.
“Our email systems do not appear to have been impacted but have been temporarily taken offline out of an abundance of caution,” the company added.
The British Columbia Utilities Commission (BCUC), which regulates BC Hydro, says it considers cyber risk a significant threat to all regulated entities in British Columbia.
BCUC said the likelihood of experiencing a successful cyberattack is increasing.
BCUC said it expects all regulated entities to mitigate cyber exposure and establish a plan to respond effectively if a cyber attack happens.
