The source of the underlying system is available on github. The UDP traffic highlighted in this post is a launcher feature for communication with the Unreal Editor.
The launcher sends a hardware survey (CPU, GPU, and the like) at a regular interval as outlined in our privacy policy(see the “Information We Collect or Receive” section). We use a tracking pixel (tracking.js) for our Support-A-Creator program so we can pay creators.
I’ll post Epic Games response in the thread here also.
