Im starting this thread so other people can add where they have found wireless routers that should not have been. If you were driving past Mount Cheyenne and got a plik from Kismet, this is the place to put up your story.
During my brief stint with 2600-Dublin, I was doing alot of War driving. One day i went into town to do some shopping, and my laptop was in my bag, wifi card on, recording everything I got. When I stopped in Mcdonalds for some refreshments i had a look at what I had caught, and had found 64 AP's in about one square kilometre. One SSID intrigued me. it was CBOI Wireless Net. The only acronym that I thought came close to CBOI that was in the area was the Central Bank of Ireland. Surely they did not have an AP.

I finished my tea, and walked over to the CBOI, and sat in the seats in front of it. Out came kismet and tcpdump. masive amounts of information filled my scrren and sure enough, they had an un encrypted AP connected to their network. As I watched the packets fill my screen, I suddenly had images of the FBI or our equivelent storming my house for hacking their network. I also had images of someone else actually doing it, and transferring the country's money to a numbered account in the bahamas. I contacted their IT department about the major flaw in their network, and a week later i walk passed, and found no AP. I had saved the day!
Anyone else have similar stories?
