How to Wardrive: Know where to go

Inspired by others, and my goal of getting a golden WiGLE badge, I went wardriving for my birthday. I was hoping for 50k, and I ended up with just over 61k. I'm less than 80k away from my goal!

But how do you pick a place to wardrive, and how do you actually do it? The easiest way is to download WiGLE on an android phone, get some transportation, and be set on your way. But if you want more detail or some tips, keep reading. 

Avon Lady Method:

  1. Find a city within reasonable distance of travel
  2. Examine the results for the past few years of the area; do not use the overall coverage of all time. 
  3. Verify if the city is desirable for wardriving
    • Little coverage in the past few years
    • Most residential areas are not covered
  4. Use maps to search and define high density residential areas (i.e. apartments, town homes). 
  5. Create an order that allows for little overlapping and in a convenient driving pattern.
  6. Use landmarks around the city to define the internal roads
  7. Wardrive
  8. Profit ("internet points")

Evansville, IN

I picked this location because of its relative distance to me, and the fact it looked like stumblers haven't touched the area recently. Below shows a map of Evansville 2020 - 2023. So for the last two years this is the only progress than Evansville has made. It looks like most of the concentration is on major roads, with only a few residential areas defined.

Figure 1

Residential areas have multiple wifi devices per dwelling, so apartment complexes have a high density of wifi and bluetooth. Those places aren't well defined by the map, so I assumed I would get a lot of results there. 

But you can't just drive around and magically get yourself to where the map is bare. It takes some planning. I call this the Avon Lady Method. Avon ladies may blanket a neighborhood with their brochures, selecting high density areas to get the most clients. Shoutout to my mom. 

I pulled up Evansville on Google Maps and got to work. Printing out a couple of paper maps of Evansville, I matched up the roads to the results on Google Maps searching for apartments. I plotted some areas on the paper map to see where I was going to drive. I then wrote the order of the apartments to the path that I wanted.

Figure 2

The numbers at the top reference a part of the map. They aren't really important. After laying out the order of the results, I broke the lists up into different quadrants of the city. Then we went down the list crossing them off as we blanketed the residentially areas. 

This would get us isolated parts of the map, but what about the center? What about the business part of the city? Using Google Maps again, I zoomed out and picked the businesses than would get the pattern I wanted and put those in order too. I called these landmarks. 

Figure 3

The result got me the same amount of networks as all of 2021 and 2021 in Evansville. Removing all results by others, here's what the wardrive worked out to:

Figure 4

There's clumps and clusters on the map from the residential areas. Using the landmarks caused the outlining on the connected streets. Combining the two maps of Evansville yielded this result of total stumblers (including me) in 2020 - 2023:

Figure 5

Comparing this figure to figure 1 shows a significant coverage change and a much more covered city. Overall this was moderately successful. About 14 hours of wardriving yielded 60k-ish results. Evansville is not a big city, and wouldn't hold a candle to large cities like SF or NYC. These areas are well covered my many stumblers; there's less opportunity to find new networks. It's currently January 31st, and here's what's already been covered in the past 31 days: 

Figure 6

It's easy to see where the major cities are and how their coverage for this year has already been explored. That doesn't mean there's not still plenty of wardriving to be had, but it does mean there's less. These numbers could rival the 60k found in Evansville, but it would be a longer, harder trip. Look at SF's coverage, I see you stumblers. 

Next post, I'll talk about the devices I used and their individual results. You'll be shocked on how good cheap, old equipment can be! Thanks for reading; happy wardriving.

The Browser Poll

 Which browser do you use? Thanks for any boosts! I wanna know! Oh cool! More internet points! I made this poll and it got some attention so I thought I'd share it.  The first 54 votes of 26,177 were erased after I edited the poll. If you edit a poll's options, such as adding one, all of the votes go back to zero. Oops. I forgot to add safari, and are large amount of people let me know. The most popular "other" answer was  Vivaldi . Other popular answers were versions of Chromium and DuckDuckGo.  While this was the final results, for a majority of the time, Firefox has a much stronger lead against Chrome. The poll started first around  when the lead was large, and as the poll moved around the fediverse, the gap narrowed.  A couple other comments sounded like "Why only one option" or why they picked their particular browser. I definitely got the information I was looking for. Check out the post  for more replies and cool facts!  Edit 12/4: A

My next talk: Come see me at CactusCon 2023!

Your smartphone is your best friend and worst enemy. Are you being listened to? Do you want to listen to someone else? This apps on your phone know more about you than you think, and there are more tools to make you cringe. Yes and no, “they are listening.” The apps are gathering so much information it seems like they are listening. This talk will discuss what privacy concerns you should have with your smartphone and will discuss how you can use your smartphone to do some surveillance of your own.
