Blue Hydra Installation Instructions

Pwnie Express   Pwnie Express | 08.10.16 | Bluetooth

 

BlueHydra is a Bluetooth device discovery service built on top of the bluez library. BlueHydra makes use of ubertooth where available and attempts to track both classic and low energy (LE) bluetooth devices over time.

You can access the github here.

Installation

Pwnie Sensor

On a Pwnie Express sensor this will be installed as a system service with the regular updates.

Non Pwnie device

On non Pwnie Express systems the files in this repository can be run directly.

Ensure that the following packages are installed:

bluez-utils
bluez-test-scripts
python-bluez
python-dbus
ubertooth # where applicable
sqlite3

In addition to the Bluetooth packages listed above you will need to have Ruby version 2.1 or higher installed. With ruby installed add the bundler gem and then run bundle install inside the checkout directory.

Once all dependencies are met simply run ./bin/blue_hydra to start discovery. If you experience gem inconsistency try running bundle exec ./bin/blue_hydra instead.

There are a few flags that can be passed to this script:

  • -d or --daemonize: suppress CLI output and run in background
  • -z or --demo: run with CLI output but mask displayed macs for demo purposes
  • -p or --pulse: attempt to send data to Pwn Pulse

Recommended Hardware

BlueHydra should function with most internal bluetooth cards but we recommend using the Sena UD100 adapter.

Additionally you can make use of Ubertooth One hardware to detect active devices not in discoverable mode.

Note: using an Ubertooth One is not a replacement for a conventional bluetooth dongle.

Configuring Options

The config file is located in /opt/pwnix/pwnix-config/blue_hydra.yml on Pwnie devices. On systems which do no have the /opt/pwnix/pwnix-config directory the service will default to looking in the root of the services directory (where this README file is located. It will still be called blue_hydra.yml

The following options can be set:

  • log_level: defaults to info level, can be set to debug for much more verbosity. If set to false no log or rssi log will be created.
  • bt_device: specify device to use as main bluetooth interface, defaults to hci0
  • info_scan_rate: rate at which to run info scan in seconds, defaults to 60
  • status_sync_rate: rate at which to sync device status to Pulse in seconds
  • btmon_log: true|false, if set to true will log filtered btmon output
  • btmon_rawlog: true|false, if set to true will log unfiltered btmon output
  • file: if set to a filepath that file will be read in rather than doing live device interactions
  • rssi_log: true|false, if set will log serialized RSSI values
  • aggressive_rssi: true|false, if set will agressively send RSSIs to Pulse

Helping with Development

PR's should be targeted against the "develop" branch. Develop branch gets merged to master branch and tagged during the release process.
