Is my wifi hacked???

OK, when I type in netstat on my Terminal, I get NO fewer than 120 "active internet connections" ***??

Care to share with us what those might be? My guess is that most are innocuous connections related to services on your machine. Do any look out of the ordinary?

probably itunes, mail, if you left safari running, various background processes that require internet connections, like autoupdates on programs, apple software update, etc.

i forgot to say above that i hope this helps with my query.

These are the addreses.

69.20.37.125 -> mac-forums.com
208.96.3.168 -> seems to be someone's apache server
208.96.3.167 -> " "

Your best bet, if you're really that concerned, is to track down what each IP is. You'd probably be wasting your time but if you want peace of mind, do some research for those IPs.
