I have found a hack in the 'disable proxies' what does this allow?

I found this hack in the disable proxies section of system preferences 'networking'  *.local,169 254/16
after finding out all my system security was deactivated i then beefed up my system, firewall, filevault & ran several virus checks.
Then a message was displayed frequently 'someone else is using your IP address.....i went to my network provider who supplied me witha new sim free of charge to my 'wireless cube' this seems to have stopped the message.
I have opened a new mail account for important emails.
I have checked 'sharing' nothing was ticked in the boxes but i did find this *my name's Macbook.local* which i have just changed back to *myname'sMacbook*
what does all this allow?
can i find out who did this?

Probably not a hack. See this thread:
