How to watch Sky directly from its CDN? angielski

I’ve read that Wavevine Widevine L3 has been hacked and so all the DRM streaming using it can be decrypted, but I couldn’t find how. Where do I find the URLs and the keys? In an article they also said that it’s possible to create a personal IPTV server that serves the channel still directly form the provider CDN. Has anybody any clue about this?
