Japanese giant Fujifilm has taken all of its servers and PCs offline after a suspected ransomware attack.
The multinational is best known as a maker of cameras and film - and more, recently, kiosks in malls and pharmacies for DIY digital photo printing - but also makes high tech medical gear including devices for rapid processing of Covid-19 tests.
A message sent to local partner around 4am NZT this morning says, "FUJIFILM Corporation in Tokyo became aware of the possibility of a ransomware attack, which has already infected multiple PCs and servers in Japan."
Systems were being closed down out of "an abundance of caution".
