Hello and welcome to the Tuesday, October 24, 2023 edition of the Sansonet Storm Center's Stormcast.

My name is Johannes Ulrich, and today I'm recording from Jacksonville, Florida.

Wrote up a little incident I had in my home network today.

Now, wasn't a breach. It was more, well,

sort of an availability issue. And the problem here is with Apple TVs. Looks like Apple TVs

have started in some recent update to act as, well, IPV6 routers in the sense that they are sending

router advertisements.

Not really clear why they're doing a comment that is quite plausible that was sent to the

post is that it may be related to the threat and matter networking protocols. These are home automation

protocols that have been implemented in recent versions of Apple TV, and well, they rely on these

unique local IPV6 addresses. However, these router advertisements can conflict with other router

advertisements that you may have in your network and lead to instabilities in IPV6.

Looks like particular Linux has some issues here about getting the priority of these IP

addresses or straight.

So if you have some issues with IP6 connectivity, in particular from Linux, it may be your Apple TV that is interfering.

If you have any other insight here, really would be interesting to hear how to possibly disable these router advertisements. Haven't really sort of seen a good way of doing that

in the apple tv setup there is pretty much no ipv6 configuration ability whatsoever and also

disabling some of the home kit functionality still doesn't disable these router advertisements.

And remember how a couple of weeks ago I think it was.

I talked about a number of war on abilities that were made public in the Squit proxy.

Squid being a very, very popular proxy server used by a lot of networks and also often embedded into other products.

Well, it looks like we have three more patches now for these vulnerabilities.
