A minimal python script to hoover up network traffic and spit it out the audio interface.
Tested and working on Raspberry Pi v3 B+ (Raspbian Stretch and Buster), Debian v8-10, Kali.
Might work on Linux VMs.
Not compatible with MacOSX at the moment. Windows compatibility not tested.
Requirements: python3, pyaudio
install pyaudio on Debian systems using:
$ sudo apt-get update && sudo apt-get install python3-pyaudio portaudio19-dev
$ git clone https://github.com/cyberfishtools/CFT--Packet-to-audio.git
Create a symlink for handy command line usage:
$ sudo ln -s /path/to/packet2audio/packet2audio.py /usr/local/bin/packet2audio
Run with:
$ packet2audio -i <iface_name>
Simple, but it must be run as root (with sudo):
usage: packet2audio [-h] [-a] [-s] -i INTERFACE [-c CHUNK_SIZE]
[-r SAMPLE_RATE] [-w WIDTH] [-t TIMEOUT] [-p]
optional arguments:
-h, --help show this help message and exit
-a, --audio-blocking non-blocking by default
-s, --socket-blocking
non-blocking by default
-i INTERFACE, --interface INTERFACE
[if0[,if1]]
-c CHUNK_SIZE, --chunk-size CHUNK_SIZE
chunk size in frames
-r SAMPLE_RATE, --sample-rate SAMPLE_RATE
frames per second
-w WIDTH, --width WIDTH
bytes per sample
-t TIMEOUT, --timeout TIMEOUT
socket timeout in seconds
-p, --print-packet print packet to console
Listen to WiFi traffic:
sudo packet2audio -i wlan0
Listen on more than one interface:
sudo packet2audio -i wlan0,eth0
Enable blocking with -a for audio and -s for socket:
sudo packet2audio -i wlan0,eth0 -a -s
Print the data written to the audio buffer with -p (hint: doesn't make sense to use without a monitor):
sudo packet2audio -i wlan0 -p
