TAIPEI (Taiwan News) - The state-owned Taiwan Power Company (Taipower) confirmed Monday that as many as 779 computers at the Taipower offices had been infected with the WannaCry ransomware in last week's attack.

While most have been repaired, some 152 computers are still affected by the malware, the company said.

The incident did not affect the electricity supply given the infected computers were used mainly for administrative work, Taipower said.

As soon as the hack was detected, the staff was immediately told to unplug their internet cables, and the virus was removed from most of the computers as of Monday afternoon, according to the company spokesman.   

The attack, one of the largest ever, is disguised as an innocuous file in an email that opens a compromised website, which then demands a ransom of US$300 or US$600 within three days to unlock the computer.

According to Europol, the global cybersecurity attack by ransomware WannaCry has hit an estimated 230,000 computers in at least 150 countries since last Friday, with Taiwan among the top targets.
