What is it

What is it?

  • War Driving Software

    • WarDriving v. The benign act of locating and logging wireless access points while in motion.

  • Access Point (AP) Identification Software


Its purpose

Its Purpose

  • Allows you to map out vulnerable APs for future use or pinpoint them for hardening


Not a sniffer or wep cracker

Not a “Sniffer” or WEP Cracker

  • Originally released as a tool that analyzed the 802.11 header and IV fields of packet to determine

    • SSID

    • MAC address

    • WEP Usage

    • WEP Key length (40 or 128 bit)

    • Signal range

    • Access point vendor


Acronyms of things this software looks for

Acronyms of things this software looks for

  • SSID (Service Set Identifier)

  • MAC (Media Access Control)

  • IV (Initialization Vector)

  • WEP (Wired Equivalent Privacy)

  • The IV of a WEPpacket is included after the 802.11 header and is used in combination with the shared secret key to cipher the packet’s data

War Driving Set-Up

GPS

  • Netstumbler will detect relative position of APs with GPS

  • Records GPS coordinate for the highest signal strength found for each access point

  • Can be used to create maps

  • Publish your maps to the web!


How it works

How it works

  • Probe Request sent to broadcast destination address

  • Response from APs contain network configuration information

    • SSID

    • WEP status

    • etc


Instructions

Instructions

  • Download and install Netstumbler

  • Set SSID or Network Name to ANY

  • Start Netstumbler and click on the green arrow on the toolbar


Filters

Filters

  • WEP usage

  • IBSS or BSS type network

  • IBSS – group of systems without AP

    • Not good to use as a bridge to internal LAN


Weaknesses

Weaknesses

  • Relies on one form of wireless network detection

    • Broadcast Probe Request

  • Wireless vendors offer an option to disable the 802.11 feature on APs


Conclusion

Conclusion

  • AP identification software

    • Can actually be used to set up your home network

  • Used for War Driving

  • Not illegal, but ethics are questioned
