Cable-Modem Security Worries

Yesterday we reported on security holes in @Home Network's cable-modem Internet access. It was discovered that some @Home customers have their Windows 95 settings configured in a way that gives other users of the service full read, write, and delete access to their hard drives and other resources.

Well, today, we learned that @Home users are not the only ones vulnerable to this problem. Steve Ringley, a subscriber to Time Warner's Road Runner service in Columbus, Ohio, told NewsRadio that soon after he signed up last month, he got a little visit from a hacker.

"Some guy came along and left a text file in my startup group over one weekend..." said Ringley.

Ringley says Road Runner was of little help in tracking how the hacker got to his computer. But on his own, Ringley determined that Windows 95 was to blame, having automatically bound his network card to both Microsoft Networking and TCP/IP when the card was installed. Unbinding networking closed the security hole.

While @Home Network says its installers ensure that Windows security is configured properly on subscriber's PCs, Ringley says Road Runner's technician didn't seem to have a clue.

"I specifically asked the guy if there was anything that I needed do to my machine to make it secure from this and he said no there wasn't. It was virtually impossible; somebody would have to know what your dynamic IP was and it changes once every hour ... and he said there was nothing I needed to do," said Ringley.

Besides having Windows configured properly, the type of cable modem used also appears to play a factor in security. Some will pass only TCP/IP data, while others are designed to use several protocols, which makes it more difficult to properly configure Windows 95's networking security. So if you subscribe to a cable-based Net access service, or if you're considering it, be sure to ask your service provider about the proper settings for your installation.

most broadband service providers require you DO NOT USE windows 95 for that very reason..........and then there is you stuck in the stone age using windows 95. If your going to use an old OS like win95 you deserve to get hacked.

Obviously the attention span and/or reading level of xband is in the 'stone age' itself, look again at when the letter was posted, then decide who needs a hack job. The guy gave up watching for comments on his article years ago, yet here is a posting finally, as ignorant as it is.
Good tech information on almost any computer related topic rarely falls on your lap; unless its your field, you're already at a disadvantage. I liked the article because it reminds me how bad we had it (on a regular basis), and how it still sometimes is. We should use techies for advice only to 2nd our own research and information in most cases.
Hopefully we're now all alot smarter-even xband, partial thanks to the small contributions made by our first generation cable techs. I owe more to pop-ups and spyware, but its all good, they all did their share and continue to ad those contributions we'd rather kick around. :-)
