Posted September 29, 200816 yr This is a WEP issue, but remember that WPA uses a shared secret also. This is the kind of thing that makes it difficult to trust wireless setups. From bugtraq: "By default, the 40-bit WEP key for the wireless router provided by Verizon to FiOS (fiber optic) and possibly DSL customers is set to the last 40 bits of the router's 48-bit MAC address. This is significant because the router's MAC address (the MAC address of it's WAN-side ethernet port) is easily discoverable using kismet without even needing to know the WEP key."
