In the wake of last month's report that 30 Canon cameras are at risk of malware attack, the manufacturer has issued firmware updates for two of its key product lines, encompassing the popular Canon EOS 5D Mark IV and 1D X Mark II.
These updates should protect users of current 1D and 5D systems from the security threat, which also potentially impacts every camera that uses the popular Picture Transfer Protocol (PTP).

"An international team of security researchers has drawn our attention to a vulnerability related to communications via the Picture Transfer Protocol (PTP), which is used by Canon digital cameras, as well as a vulnerability related to firmware updates," notes the manufacturer.
"Due to these vulnerabilities, the potential exists for third-party attack on the camera if the camera is connected to a PC or mobile device that has been hijacked through an unsecured network."
Canon has now released firmware for the following cameras to address the issue:
Canon EOS-1D X (Version 1.2.1 is available for download)
Canon EOS-1D X Mark II (Version 1.1.7 is available for download)
Canon EOS-1D C (Version 1.4.2 is available for download)
Canon EOS 5D Mark III (Version 1.3.6 is available for download)
Canon EOS 5D Mark IV (Version 1.2.1 is available for download)
Canon EOS 5DS (Version 1.1.3 is available for download)
Canon EOS 5DS R (Version 1.1.3 is available for download)
Canon EOS 80D (Version 1.0.3 is available for download – already released)

As discussed in our earlier story, this is not a Canon-specific issue – any camera that uses the PTP protocol is potentially affected by the same security risk.
"While the Canon EOS 80D was the one tested in this demonstration, we do believe that similar implementation vulnerabilities could be found in other vendors as well, potentially leading to the same critical results in any digital camera," we were told by Eyal Itkin, researcher for Check Point, which discovered the vulnerabilities.
At present, there have been no confirmed reports of malicious activity or attacks due to the security holes in the PTP. However, Canon has issued a number of workarounds – which should also help protect users of any affected camera, Canon or otherwise:
- Ensure the suitability of security-related settings of the devices connected to the camera, such as the PC, mobile device, and router being used.
- Do not connect the camera to a PC or mobile device that is being used in an unsecure network, such as in a free Wi-Fi environment.
- Do not connect the camera to a PC or mobile device that is potentially exposed to virus infections.
- Disable the camera’s network functions when they are not being used.
- Download the official firmware from Canon’s website when performing a camera firmware update.
