[Discuss] Ban UPnP? Re: The Mirai botnet

[richb at pioneer.ci.net (Rich Braun)]

Finally, I see a company name attached to this Mirai botnet problem: Hangzhou
Xiongmai Technologies, whose devices leave an essentially unprotected (and
unprotectable) telnet server open.

The article mentions nothing about UPnP, though, so I'm still left wondering
how the attack happened. Another article notes Xiongmai's response, which
includes a product recall:

And their IPC (IP camera) product specs do include UPnP, so presumably it's
enabled by default and causing also-unsecure Netgear/DLink/Linksys defaults to
leak their open TCP ports out onto the open Internet.

What will these router vendors' response be? And is it appropriate to begin a
campaign to discontinue support for UPnP (by all products everywhere), as was
done a few years ago for the non-secure wifi WEP auth protocol?
