Flag : ECTF{id}

Now we can use YouTube Geofind in order to find a video based on it's geolocation tag since we have the position of the wifi router.

We've got that video that is matching perfectly the location of the WiFi hotspot and it's a Matrix themed video matching the CTF theme. We found it !

The flag is the id of the video so we just have to copy/paste it from the URL :
