If you own a Canon printer, be careful before throwing it away or giving it away

Canon is issuing a warning to users of its home, office and large format inkjet printers about a security issue.

It was discovered that Wi-Fi connection settings stored in memory are not erased properly during resetwhich may allow other people to get the password of your WiFi network.

If repair technicians, purchasers or prospective users access the printer’s memory, may get connection details from your Wi-Fi network.

The information stored on a Canon printer varies by model, but typically includes the network SSID, password, network type (WPA3, WEP, etc.), assigned IP address, MAC address, and the network profile.

Canon identified 196 printer models affectedincluding E, G, GX, iB, iP, MB, MG, MX, PRO, TR, TS and XK series inkjet printers, professional inkjet and wide format inkjet.

To resolve this issue, Canon advises owners of affected printers to clear their Wi-Fi settings before third parties have access to the printer, for example for repairs or when giving or selling the device to someone else.

Finally, it is important to apply firmware updates available for your printer model and disable unnecessary services, such as cloud printing or remote management interfaces, to improve overall device security.
