iPhone chip maker Taiwan Semiconductor Manufacturing Co. saw several of its factories knocked offline Friday night because of a virus, but it's unclear whether production of the iPhone components was affected, said a report Saturday by Bloomberg.

The virus wasn't introduced by a hacker, TSMC told the publication, adding that the company had contained the problem and restarted some manufacturing, though some facilities won't be back up till Sunday.
