I'm trying to ascertain if I am at risk...
About 1 week ago I connected to the University of Minnesota's "guest" wifi network. I was asked to provide an email address and that's all. I was online.
But I use Little Snitch so granted access to a flurry of temporary connections to when they popped up as I was in a rush to connect. Possibly a bad move, but I was guided through this process by a U of MN tech guy so I felt ok about it. It worked for the weekend and that was that. I didn't use my email or login to any websites, I just pulled up a YouTube video for a group's presentation.
All seemed well... But, when I got home, I received 2 Little Snitch notifications: NetAuthAgent and nmbd. I don't know if any of this is normal but NetAuthAgent showed up as ~myusername but nmbd showed up as root.
Also, my hard drive space also went down to zero on a random instance when Safari froze up, but I don't have a screen grab of that.
Also, in my Finder, there was a "PC Server" device listed under Shared. This was new. This freaked me out.
Not only have I been unable to stop NetAuthAgent and nmbd from prompting me for access every single time I start my computer, the times I have experimented/troubleshot the issue and give them permission, I'm getting the PC Server listed under Shared.
I've run MacScan and I can block it out by denying it access via Little Snitch, but I wanted to ask the digital Jedi out there if this was normal, because when I try to click "Connect To", it give me the following error...
I've seen NetAuthAgent & nmbd before, but not like this.
In summary, these instances started happening constantly after I used the University's network and has not gone away.
Thanks in advance for your time,
P.S. I'm running the latest software on a MBP, 17" (Mid '09)
