  1. If its open anyone with knowlege and in range can see anything you do, https does not help (if you get a message that the certificate is not valid, people are listening)

    If its WEP see above

    If its WPA2 with a weak password see above

    If its WPA2 with a strong password anyone within the network can see everything you do.

    Here is how it is done over wifi (or lan)

    Use some software that monitors any change in arp packets to be safe

    You are referring to the condos AP's here right? Not the end users on his Mac as he is not runnng it in hotspot mode.

    User 1 connects to condo wifi1

    User 2 also connects to wifi1

    User 1 and 2 are both using wifi1 to acess internet

    User 1 and 2 are in a local network

    User 3 can sit in his car outside the house and "hack" the network so he gains access to wifi1

    User 3 can the trick user1 and 2 to connect to his laptop and listen to all traffic (user 3 then sends it to wifi1)

    To be safe u need to have WPA2 with a good password running on wifi1 so User 3 cant access wifi1

    a good password is ex. fgFG56%%ffdfDg5%&%hH

    User2 can still trick User1 since he knows the WPA2 password

    User1 needs a firewall that detects changes in arp packets to be safe

    In a condo its usually safe since the signal dont go so far through walls etc..

    Its the open hotspots at mc donalds and such that people should be afraid off.

    It is very easy to sniff passwords and spy there

    edit: typos
