Looks like upnp puts Chromecast public on port 8008, a cool curl command will play a YouTube video on your device...

curl -H “Content-Type: application/json” http://IP_GOES_HERE:8008/apps/YouTube -X POST -d ‘v=VIDEO_ID_HERE′

Someone with one & uPNP on can try it and see if it works for their WAN IP

Did ATV just get hacked

No, it did not.

It's a chromecast/upnp issue from what I've read.
