O.MG Cable is here and the way technology is going, more of those devices will be available to the common user.
This kind of USB attack isn't new and there is plenty of devices out there ready to do some hardware or software damage to your computer (Rubber Ducky, BadUSB, USBKill...). But they are getting smarter and being disguised as devices of daily use like a cable.
Question: Is there a software that would block all
udev triggers and ask for the user if he wants to allow a new usb device to be enabled, creating a device whitelist? A feature to execute an initial scan to register the devices that are already connected is much appreciated...
I'm thinking that if O.MG Cable is a HID device, it should be safe to not allow it to be mapped neither access system resources (it would show "HID Device" when plugged and the user could refuse it).
