This isn't about URL's it's about game lobby's and servers. If a game doesn't have a dedicated server then a user has to create one thus he is the Host. While these servers are only up for a short time they give any person a connection to your computer in a sense. What I'm worried about is when someone connects to me or when I connect to someone do I suddenly become at risk? So far from what I've seen the hackers can only manipulate the server on their end EX. Unlimited life, Ammo and other such things other people in the sever aren't given these powers. But I've also seen them spawn in things meaning they can mess with the server. This is where my worry comes in. I'm worried that they might be able to send something to my computer while they are connected or that the host will be able to infect whoever joins.
