pls can u tell me what is this traffic attached

It’s packets addressed to TCP port 80.
You need to break further into the packet to determine the higher layer headers for further information.

also shouldn’t this be an unauthorized user and be unable to pull anytraffic since he didnt regester in the active hotspot users?
