Here is a scenario (this depends on how close your house is to the street). A van that is painted to look like a bellsouth truck (or name your utility) pulls up into your neighbor hood and stops on the corner. It sits there for say 45mintues 1 hr and drives away. What could that truck have done?
1. 45minutes to 1 hr is enough time to pull out your WEP keys from your WIFI network and have full access to traffic on your net (except the SSL stuff). Can also now go behind your firewall (depending on setup) and behave as a normal internal network client. Unless you change your WEP key, he/she now has easy access to your private net when ever they feel like driving by again. 2. If you have standard Analog Cordless phones, if you happened to make a call to your bank, he/she could now have full records of your bank account number, pin and pass code depending on the conversation. Also any other phone conversations. 3. That may even be enough time to break into some digital cordless phones, though I'm not as well versed on that stuff. Multiply that by say 2-8 houses depending on how big each lot is and how big of an extended antenna the van has hidden inside. Now it may not be worth while for someone to go to all the trouble of scanning, but maybe it is in a more well todo townhouse/condo type area? I'm certainly not protected 100% against any of this, but I am aware of the risk I run with having WIFI and Cordless phones. You just have to be aware of it, and gauge your risk. Might be a good argument for a VPN over the wireless to a Linux authentication server :-). At 10:58 AM 5/17/2002, you wrote: >Have there been any cases of this?
