Re: mDNS and SSDP vulnerabilities a suggestion for devices in the DMZ
Thanks for clarifying. It all makes sense now. For now I have just used option 1 and forwarded 5353 to an un used ip address. Hopefully this resolves the matter otherwise I will go for option 2 to specifically forward ps4 5353 incomings to a higher port number.
The report doesn't give a whole lot of identifying information, but rather only says "_spotify-connect._tcp.local.".
So, I can at least tell you that Spotify is the culprit, but I can't tell you /what/ device the Spotify service is running on.
Hope this helps,
So it's spotify, ironically spotify is run and partially owned by Daniel Ek. Who also ran Napster and μTorrent, so no surprise when I discovered that Spotify caches songs locally and also streams them to other users. It's partially decentralised. Hence port 5353 mDNS.
