    How to protect against WPA2 vulnerability (KRACKs) - Large format printers with Wi-Fi feature

    Thank you for using Canon products.

    With the recent disclosure of WPA2 Vulnerability (KRACKs), we would like to provide information on proper safeguards to mitigate risks associated with this vulnerability when using Canon products.

    Supplementary Information on KRACKs:

    A vulnerability known as KRACKs in the standard wireless LAN (Wi-Fi) encryption protocol WPA2 has been made public recently. This vulnerability allows an attacker to intentionally intercept the wireless transmission between the client (terminal equipped with Wi-Fi functionality) and the access point (the router etc.) to perform potentially malicious activity. For that reason, this vulnerability cannot be exploited by anyone outside the range of the Wi-Fi signal or by anyone in a remote location using the internet as an intermediary.

    Affected Products:

    All large format printers with Wi-Fi feature.

    Note: The following service is not affected by KRACKs vulnerability as the communication is encrypted.

    • Extended survey program

    Workaround:

    • Use wired connection (e.g. USB cable or Ethernet cable)
    • Use Wireless Direct (e.g. Print without using wireless LAN router)


    Please refer to the product's User's Guide for detailed setting change procedures.

    We would also recommend you to take measures against the vulnerability of the connected devices including PCs and smart phones
