Title: RE: cable modem security

That assumes you can put the "cable modem" into a promiscuous mode....  The cable modem is essentially a transparent bridge... Does anyone know of other devices that allow you to access the cable medium?  Is there a online copy of this article in 2600?

From what I've heard, the cable modem runs over the existing cable TV lines strung throughout you're area. Anyone with a packet sniffer can tap in and see all transmissions. There is a great article about it in 2600 (the one with the orangutang the cover)\
