    NMEAsnitch works to detect malicious NMEA serial data.

    This tool was first presented at Defcon 25.

  • NMEAdeysnc

    While tardgps worked by changing time by manipulating GPS signals, NMEAdesync manipulates time through the NMEA serial data sent between the GPS receiver and the NTP device.

    This tool was first presented at BSidesCBR.

  • tardgps

    Dave Robinson has continued his work into GPS Spoofing and its implications. Dave has developed a tool call tardgps which allows an attacker to change the time on a GPS-enabled NTP server without crashing the NTP daemon.

    This time manipulation was first presented at Kiwicon X in Wellington.
