Hello, I'm a new member here and need you guy's help. I've taken many steps since March of this year to keep my wireless network from being hacked, from upgrading to WPA from WEP, changing the password, MAC Filtering(which I found out is useless), and decreasing the transmit channel.
Then sometimes I would see my Mail.app launch on it's own, and decided to use Little Snitch. I noticed a lot of things going on that were still connecting to my computer w/o any apps running at all, just by being connected to the internet. Especially things trying to connect to Finder and a lot of connections in mDNSResponder(shows all things connected to wireless network)(usually shows about 6 connections!!!).
I'm on Comcast, and they require us to use these Netgear routers that are distributed by them that do not currently have WPA2 enabled. So, I log into my router and decided to add 'Parental Controls' with websites that had keywords "porn", "murder", "sex", etc. Since I'm the only one that really uses my home network, so I suppose, and I don't associate myself with any websites that deal with murder, sex or porn, this would possibly exposed if my network was STILL compromised. And after checking the 'Parental Control Internet Activity Log' from logging into my router connected to the Comcast Home Networking system, I noticed constant attempts to access sites w/ porn, and sex.
Now this perv has used my MAC address and is using that to access my wireless network. I've tried changing my MAC Address by following some tutorial online using Terminal, but it went back to my original MAC address once I restarted..I need to figure out how to eliminate this problem, ONCE AND FOR ALL.....hopefully the experts here at MacTalk can help me.
Current setup:
Macbook Pro
Leopard 10.5.6
Comcast Home Network
WPA
