As you may know, we recently released our WiFinger tool for fingerprinting wireless access points. However, fingerprinting tools are only as good as their signature database, and while we have a handful of popular signatures already, we need more. So if you want to contribute to this project, one of the best ways to help is to send us pcap files of 802.11 beacon packets for access points and routers that we don’t already have in our database.

Specifically, here’s what we’ll need:

• If the access point supports WPA and/or WPS, enable both of those features. This can help us in creating more robust signatures.
• Place your wireless card in monitor mode and use Wireshark to capture the access point’s beacon packets (we only need one beacon packet, so don’t feel like you have to capture large amounts of data).
• Save the Wireshark capture and send us the pcap file along with as much information as you can about the access point (vendor, model, firmware version, hardware revision, etc).
• Send all submissions to dev [at] sourcesec.com.
