Just posting as a heads up for fellow canon users there is a way for people to lock you out of your camera's sd card canon put out a alert but never told people it seems.
Alert here: https://global.canon/en/support/security/d-camera.html
Heres the worrying part: its not at all safe even via usb since PTP is unsecure best option is to use a card reader and dont connect to free wifi.
