I run a small private hub and have never seen this before.. (updated to 1.3.5 today). Hubsoft is ynhub
some how some random user managed to connect to one of my shared files. Said user has never been a member of my hub, I was in no other hubs at the time.. wondering how this person connected. My hub requires nick/pass that is only set by me. This was my laptop he connected too (wireless enabled). The hub runs on my main rig in another room of the house.
