Any interest in building up something like that here?
I do a bit like this with routers. Those backdoors are usually in there from telco companies to push some updates or get information from those systems. A lot of the easier stuff is on cheap cameras for example where the manufacturer just doesn't think about one ever breaking into that thing with a JTAG or serial port.
A good start is to use binwalk, a jtagulator, some buspirate and reverse engineering the software on there with ghidra and take the unix subsystem in general.
Its a lot of work.
