Trackerjacker – Maps and tracks wifi networks and devices through raw 802.11 monitoring

Like nmap for mapping wifi networks you’re not connected to. Maps and tracks wifi networks and devices through raw 802.11 monitoring.

Install

pip3 install trackerjacker

Supported platforms: Linux (tested on Ubuntu, Kali, and RPi) and macOS (pre-alpha)

PyPI page: https://pypi.python.org/pypi/trackerjacker

trackerjacker can help with the following:

  • I want to know all the nearby wifi networks and know all the devices connected to each network.
  • I want to know who’s hogging all the bandwidth.
  • I want to run a command when this MAC address sends more than 100000 bytes in a 30 second window (maybe to determine when an IP camera is uploading a video, which is indicative that it just saw motion).
  • I want to deauth anyone who uses more than 100000 bytes in a 10 second window.
  • I want to deauth every Dropcam in the area so my Airbnb hosts don’t spy on me.
  • I want to be alerted when any MAC address is seen at a power level greater than -40dBm that I’ve never seen before.
  • I want to see when this particular person is nearby (based on the MAC of their mobile phone) and run a command to alert me.
  • I want to write my own plugin to run some script to do something fun every time a new Apple device shows up nearby.

Usage

Find detailed usage like this:

trackerjacker -h

There are 2 major usage modes for trackerjacker: map mode and track mode:

Map mode example

Map command:

trackerjacker -i wlan1337 --map

By default, this outputs the wifi_map.yaml YAML file, which is a map of all the nearby WiFi networks and all of their users. Here’s an example wifi_map.yaml file:

Note that, since this is YAML, you can easily use it as an input for other scripts of your own devising. I have an example script to parse this “YAML DB” here: parse_trackerjacker_wifi_map.py.

Example: Track mode with trigger command

Track mode allows you to specify some number of MAC addresses to watch, and if any specific devices exceeds the threshold (in bytes), specified here with the -t 4000 (specifying an alert threshold of 4000 bytes) an alert will be triggered.

trackerjacker --track -m 3c:2e:ff:31:32:59 --t 4000 --trigger-command "./alert.sh" --channels-to-monitor 10,11,12,44
Using monitor mode interface: wlan1337
Monitoring channels: {10, 11, 12, 44}

[@] Device (3c:2e:ff:31:32:59) threshold hit: 4734

[@] Device (3c:2e:ff:31:32:59) threshold hit: 7717

[@] Device (3c:2e:ff:31:32:59) threshold hit: 7124

[@] Device (3c:2e:ff:31:32:59) threshold hit: 8258

[@] Device (3c:2e:ff:31:32:59) threshold hit: 8922

In this particular example, I was watching a security camera to determine when it was uploading a video (indicating motion was detected) so that I could turn on my security system sirens (which was the original genesis of this project).

Example: Track mode with foxhunt plugin

trackerjacker -i wlan1337 --track --trigger-plugin foxhunt

Displays a curses screen like this:

  • Note that foxhunt is a builtin plugin, but you can define your own plugins using the same Plugin API.

Example: Track mode with trigger plugin

$ trackerjacker --track -m 3c:2e:ff:31:32:59 --threshold 10 --trigger-plugin examples/plugin_example1.py --channels-to-monitor 10,11,12,44 --trigger-cooldown 1
Using monitor mode interface: wlan1337
Monitoring channels: {10, 11, 12, 44}
[@] Device (device 3c:2e:ff:31:32:59) threshold hit: 34 bytes
3c:2e:ff:31:32:59 seen at: [1521926768.756529]
[@] Device (device 3c:2e:ff:31:32:59) threshold hit: 11880 bytes
3c:2e:ff:31:32:59 seen at: [1521926768.756529, 1521926769.758929]
[@] Device (device 3c:2e:ff:31:32:59) threshold hit: 18564 bytes
3c:2e:ff:31:32:59 seen at: [1521926768.756529, 1521926769.758929, 1521926770.7622838]

This runs examples/plugin_example1.py every time 3c:2e:ff:31:32:59 is seen sending/receiving 10 bytes or more.

trackerjacker plugins are simply python files that contain either:

  • Trigger class which defines a __call__(**kwargs) method (example: examples/plugin_example1.py)
  • trigger(**kwargs) function (example: examples/plugin_example2.py)

And optionally a __apiversion__ = 1 line (for future backward compatibility)

Example: Configuring with config file

trackerjacker.py -c my_config.json

And here’s the example config file called my_config.json:

{
    "iface": "wlan1337",
    "devices_to_watch": {"5f:cb:53:1c:8a:2c": 1000, "32:44:1b:d7:a1:5b": 2000},
    "aps_to_watch": {"c6:23:ef:33:cc:a2": 500},
    "threshold_window": 10,
    "channels_to_monitor": [1, 6, 11, 52],
    "channel_switch_scheme": "round_robin"
}

A few notes about this:

  • threshold_bytes is the default threshold of bytes which, if seen, a causes the alert function to be called
  • threshold_window is the time window in which the threshold_bytes is analyzed.
  • devices_to_watch is a list which can contain either strings (representing MACs) or dicts (which allow the specification of a name and threshold)
    • name is simply what a label you want to be printed when this device is seen.
    • threshold in the “Security camera” is how many bytes must be seen
  • channels_to_monitor – list of 802.11 wifi channels to monitor. The list of channels your wifi card supports is printed when trackerjacker starts up. By default, all supported channels are monitored.
  • channel_switch_scheme – either default, round_robin, or traffic_based. traffic_based determines the channels of most traffic, and probabilistically monitors them more.

Example: Enable/Disable monitor mode on interface

Trackerjacker comes with a few other utility functions relevant to WiFi hacking. One of these is the ability to turn on monitor mode on a specific interface.

Enable monitor mode:

trackerjacker --monitor-mode-on -i wlan0

Disable monitor mode:

trackerjacker --monitor-mode-off -i wlan0mon

Note that trackerjacker will automatically enable/disable monitor mode if necessary. This functionality is just useful if you want to enable monitor mode on an interface for use with other applications (or for quicker starup of trackerjacker, if you plan to be starting/exiting to test stuff).

Example: Set adapter channel

trackerjacker --set-channel 11 -i wlan0

Note that trackerjacker will automatically switch channels as necessary during normal map/track actions. This option is just useful if you want to set the channel on an interface for use with other applications.
