Most of you know about Wardriving, but how many of you know about Warbussing?
Feeling like being a Wifi Pioneer (or just cheap, you pick), I decided to go out and ‘warbus’ today in the city center of my city using a specially outfitted Sony Clié PDA. I used the device to detect local APs (Access Points, ie. Wireless Routers), and initiated scans whilst on the bus during during its route in the city core.
The bus was travelling relatively fast, so every Wifi sweep that I did in search of APs yielded a different set of results every few seconds as I entered and left the zones of each point. I then got off the vehicle and proceeded to backtrack on foot to see what I had initially missed:
Interestingly enough, each scan still yielded different results from any one spot. In one instance it picked up a router that was inside a restaurant a very distant block away (the SSID of the AP was of the same name as the eatery). It should be noted that pretty much all of these APs were WEP enabled.
