DNoiSe

DNS noise generator that looks at your network activity and blends in. Requires pi-hole to run.

DNoiSe blended into organic traffic The blue graph line marks queries generated by DNoiSe, blending in with peaks and valleys of organic traffic.

Why bother?

  1. Does your DNS provider log your queries? If it does, you should change your DNS provider. But if you can't, this will make it harder for them to profile you based on your DNS requests. Not impossible, but harder.
  2. Plausible deniability.

Dependencies

pip install pandas
# Raspberry Pi users should use 'sudo apt-get install python-pandas' instead

pip install requests
pip install dnspython

Recommended setup

  1. Run this on the same machine that hosts your pi-hole instance.
  2. Pair this with dnscrypt-proxy or some other DNSCrypt/DoH client to make sure your ISP can't snoop on your queries.
  3. Put this in your crontab -e to make it run after reboot. @reboot /usr/bin/python /home/pi/DNoiSe.py
  4. That's all there is to it. The script will sample network activity every minute and add 10% extra DNS queries made randomly to Cisco's top 1M domain list.
