Researchers at Israeli-born Check Point, the world's largest cyber security firm, have tested the PTP - Picture Transfer Protocol, which defines digital image transfer from the camera directly to the computer in Canon's EOS 80D, the leading advanced Canon DSLR cameras, focusing on the USB interface and connection to the cameras WIFI network.
They identified serious security weaknesses in the protocol, which allow hackers to take control of the camera's files and damage the camera, including infrared attacks where all content is encrypted until a ransom payment is made to the hackers. Other weaknesses were identified that allow the camera to be attacked by the computer via the same USB connection in the camera.
