A new report by security experts at Check Point Research demonstrates a glaring vulnerability in modern DSLR cameras: Photo Transfer Protocol. Worse yet, the researchers were able to exploit vulnerabilities in PTP/IP, which transfers photos from a DSLR to a computer wirelessly. This allowed the researchers to infect a nearby DSLR wirelessly and encrypt all of the camera's photos.
