I don’t really understand your snippet. But yeah i think the issue with IoT devices having connection to any other network device at all is that if they have a security hole that can be exploited through a malicious USB drive or BT or any other compromised device it can connect to, that it can act maliciously in a number of ways. The only true security for devices that can’t get patched is a complete air gap for any connected devices.

I have a pi-hole. And my asus router can probably close all outbound traffic. I also think USB printing is fine tbh. I don’t need AirPrint.

Isn’t the concern that if you infect a printer locally, you can use that to “pivot” to another device on that network that IS connected to the internet?

This is being widely reported, but I still haven’t been able to figure out exactly what printers and what firmwares this is applying to. I’ve got a brother laser printer, but it’s been unplugged for a few weeks now as I moved around my home office. I do usually use it on wi-fi for wireless network printing, but I haven’t tapped update on it for months. I would like to know what I should look for to identify if this is an issue for me.

Obviously I’ve got a few possible scenarios: 1 - my printer is updated past this firmware already: A. I can only buy brother toner B. I figure out to downgrade, which sounds tricky. C. I buy a new(old) printer? 2 - my printer isn’t updated: A. I turn off network functions on it entirely, printing using the USB port or with a USB cable. B. I block internet access on my network, but allow it to work locally. This is potentially risky if i do setup wrong or change my network config and forget about it. C. I say fuck it and only buy brother toner since it’s probably going to impact pricing either way
