Unknown SMB connections (hacked?)
I'm getting a lot of messages in my system.log along the lines of:
Apr 24 09:30:00 computername smbd[18939]: 123.45.67.89 SMB client not supported - Unicode strings are required
Apr 24 09:30:00 computername sandboxd[18997] ([18995]): smbd(18995) deny job-creation
I don't recognise the IP addresses, and there seem to be log entries every 5 minutes or so. I only have a few ports fowarded on my router and they're not related to SMB.
Am I right in thinking these are incoming, not outgoing connections? Any idea if I can find out how these connections are reaching my computer? Can I find a list or log successful SMB connections?
