Wardrive shows Wireless Networks still Wide Open
Wardriving usually consists of driving around in a vehicle searching for Wi-Fi Wireless networks using Aircrack-NG, Netstumbler, Kismet or another similar program. Information can be gleaned from available Wi-Fi networks including what type of security that they are using. It is the modern version of wardialing which was very popular in the 80’s and early 90’s where hackers would call blocks of numbers looking for a computer.
According to the graph, 13% of the Wi-Fi networks had no security at all. And a whopping 45% were using WEP, which has been cracked a long time ago. Only 18% were using WPA2. So in effect, 58% of the detected networks would have been easy pickings for a hacker. They might as well have hung a big “Welcome!” sign on their network.
San Francisco did not fare much better:
I was actually shocked at the high percentage of unsecure Wi-Fi systems. With the dangers of Wi-Fi so well-known, it just doesn’t make sense. In fact for a product to even qualify for the Wi-Fi label, it must have WPA2 security. And that has been the standard since 2006!
You would think at this stage of the game, manufacturers would have taken the choice out of consumers hands and make the default security WPA2 out of the box.
Please check your Wi-Fi security settings to be sure that they are not set to “WEP” or worse yet, “None”. Also, if you have a wireless box that only supports WEP, it needs to be replaced with a newer, more secure version. When hackers scan your network from across the street, you want them to find a “No Admittance” sign!
