PPI-Geolocation: The Next Generation of 802.11 Visualization and Geo-Location

Presented at ToorCon San Diego 13 (2011), Oct. 9, 2011, 6:30 p.m. (20 minutes)

Johnny will present his results of his latest R&D efforts: PPI-Geo location. PPI-Geolocation is a new technology that allows applications to encode position, orientation, signal strength, and antenna characteristics into a industry-standard pcap file. Johnny will walk us through the concepts behind the standard, as well as a tour of the entire stack of open source software support. To date, this includes Kismet, Wireshark, scapy, and the associated SDK.

    Johnny Cache is a world renowned rock star of wireless hacking. In the past few years he has published an award-winning thesis on 802.11 driver fingerprinting, re-written aircrack in C++ (for aesthetics), and published two editions of Hacking Exposed:Wireless. Having written the book on wireless hacking he decided to go the extra mile and create a specification for geo-locating wireless networks. You know, so he could find more networks to hack. He does not yet have his CISSP.
