I'm using RaiderSoft chat integrated with Threads. In the chatroom, you can query another users IP (which is helpful for chatroom moderators if someone is causing trouble).
This morning I had a user write to me about people using chat on a broadband connection, and how they were vulnerable to backdoor programs, trojans, and something called "ants" (which I've never heard of), if an unscupulous person goes into chat and finds out a users IP. She insists that the only people vulnerable are broadband users who are in chat, and that firewalls won't help.
I have no idea what she's talking about. As my board is heavily moderated and chat is by "invitation only", I'm not worried about trouble. However, I'm afraid this user is going to start spreading rumours about the chatroom being unsafe.
Can anyone explain to me what she's talking about, if it's true, and what I can do about it?
