I have just found a post from way back in January 2018 from Lonerangefinder the title of which is 'WiFi Security with Fuji Remote'.
20 months after that post was made the story on 12th August 2019 is that cameras apparently can be infected with ransomware
by remotely tricking the camera into installing a malicious firmware update.
A test was conducted on a Canon EOS 80D. Access via WiFi or Bluetooth.
Give us the money and we'll let the pictures go. You get to view the threat via the EVF or Screen.
Sources are Threatpost, Mashable, Engadget, PCMag also ShortList all reporting on research from Check Point.
What I would like to know is is it possible to turn off the WiFi or Bluetooth on an X-T2?
