I am not sure why you had to go through such hoops to get a Comcast installation working. I have performed a dozen or so Comcast installations for friends and family without a hitch. The CD that you used is completely unnecessary. All you have to do is hookup your equipment, call Comcast to register your modem's MAC, and poof, you're done. I am not writing this to insult you (or your intelligence), but instead to hopefully save you time should you need to perform a Comcast installation in the future. -Thomas -----Original Message----- From: Gandalf The White [mailto:gandalf () digital net] Sent: Sunday, July 18, 2004 10:14 PM To: security-basics () securityfocus com Subject: Comcast Cable Setup Security Issue Greetings and Salutations: I am beginning to get a feel for why Comcast is at the top of the list for zombie spam boxes. I just set up an account for a friend who had a connection on the Comcast cable network. The instructions on the included CD-ROM (as soon as the CD started up) was to turn off all Anti-Virus and Firewall software on the computer. I called up Comcast tech support and told them that I was I was nervous about doing this, but I was assured that my computer would *only* be talking to the Comcast activation server. Lets just ignore that the computer would be talking to all the other machines on my local cable segment also. I had a router with firewall in between the computer and the Comcast network so I went ahead and deactivated the anti-virus and firewall software on the computer. I got half way through the activation and all of the sudden the process dies. Claimed I could not reach the HTTPS server or that I had not activated within the time allowed. I tried everything to start up the process again with no success. Called Comcast tech support. The tech (he was very efficient and nice) told me to DISCONNECT THE COMPUTER FROM THE ROUTER AND PLUG THE COMPUTER DIRECTLY INTO THE CABLE MODEM. This made me EXTREMELY nervous. I now have a computer (that was patched and up to date of course) ... BUT ... The antivirus and personal firewall software was PURPOSEFULLY turned off. By Comcast instructions. He walked me through connecting to the Comcast website and finishing up the activation steps. I tried (in the middle of his instructions) to ask if I could hook back into my router for a modicum of protection and was told no, I had to finish the setup. When I finished the setup (again, he was very nice and pleasant) I rebooted, hooked the computer back to the router/firewall, verified my antivirus and firewall were working and indeed everything worked fine. Being a computer / security professional I was (of course) thinking about all the very bad things that could happen to this computer while following Comcast's instructions. I know (and I think it is almost criminal) that many cable companied hook PC's up to a cable modem *all the time* without antivirus / firewall / updates / any kind of protection. But you would think that an installation would not require you to take away any kind of protection that a computer has. I can see some overzealous PC owner deleting the anti-virus and firewall software just to get their cable modem working.
