Figure 5: StumbVerter, by Michael Puchol (Sonar Security), from http://www.sonar-security.com

NetStumbler and Kismet log wireless access point and GPS data to their own specified file formats, binary formatted .NS1 for NetStumbler and a combination of .CSV .GPS .XML text and xml formats for Kismet. As you can see, a conversion process is needed to convert data into wi-scan format for StumbVerter.

Just as an overview, there are several different file formats that are used to log wardriving sessions. At least five file formats exist:

  • o

    Wi-scan summary

    • o

      Wi-scan extended

    • o

      CWGD (Common Wireless GPS Data)

    • o

      Netstumbler .NS1

    • o

      Kismet .GPS .CSV .XML

Meanwhile, NetStumbler’s built-in converters and several scripts written by Medic and c0nv3r9 are available and sufficient for converting between these formats (blackwave, p.1).
