Wardriving is the systematic search for wireless local area networks (WiFi networks) from a vehicle. The term “Wardriving” implies something like going to war and is sometimes also referred to as “wireless network mapping” or “access point mapping”. Since any means of transportation can be used, other terms have emerged alongside wardriving, such as warwalking (searching for WLANs on foot) and warbiking (searching by bicycle).
Equipped with a laptop and an external antenna to extend the range, the classic wardriver tracks down WiFI networks. These are logged with a WiFi sniffer, a program that finds wireless networks, in order to create digital maps.
The reasons for wardriving can vary. In addition to the search for open access for personal use, others do it as a hobby. There are also those who look for security vulnerabilities and report them to the network operator in order to reduce the number of open WLAN networks.
On the other hand, some wardrivers have criminal intentions, penetrating open networks to steal data or use the network as a stepping stone for further attacks, such as installing malware. The risk of being detected is extremely low.
Wardriving is not illegal in itself, as there are no laws that prohibit people from collecting data from wireless networks to create maps. However, it becomes illegal as soon as someone enters unsecured networks without permission in order to access private information. In addition, it may constitute a violation of § 30, paragraph 1 of the Road Traffic Act if someone is disturbed by “senseless driving around in built-up areas”. The ban on cell phones also applies, which is why the driver is not allowed to operate such devices while driving.
