Hi,
can I run this one past you please. In the past I have done something called wardriving
as a hobby. Essentially this involves driving around in a car/bike with a laptop/handheld
connected to a wireless aerial on the roof and a GPS unit.
You then record the location of access points you pick up on a map. Sounds odd eh?
I'm a radio ham and have odd hobbies but I find it fun. I've been doing it for a number of years and I find it interesting to see the increase in home wireless networks.
It's also possible to see which access points you pass are running with some kind of security and which ones are not.

As I'm always looking for ideas to increase customers for my new PC repair, network etc company, I wondered about doing some wardriving (lets call it "wireless network security auditing") in my locale and then doing a leaflet drop in areas where I find unsecured access points, telling people that they could be running a wi-fi network which is possibly open to abuse.
I could then offer to secure their equipment for my normal call out rate.

What do you think? I understand I dont want to come over too frightening in my letter etc?

Thanks

D
