I've received several messages over Steam from people in various groups that have had their accounts hijacked.
They will send you a message about joining a group, and have a link with a URL like steamcommunity.t35.com (DO NOT GO THERE).
Something about having only 5 members, please join, etc.
It's a phishing site. You enter your username and password, as if you were signing in to Steam Community. They keep your credentials and log in to your real steam account.
I was already wondering why someone would want to talk with me.
