dnstwist

This is a tool that will fetch potential typo-squatting or IDN domains which could be targeting your domain for spear phishing.
Permutations will be fetched from https://dnstwist.it/.

It will take into account the registration and/or last updated WHOIS information and a potential whitelist.

Domains identified can be sent to Slack for automated alert purposes.

Usage

First create a configuration file:

# log settings, optional
log:
  # log level to use
  level: info

# the domains you'd like to monitor, required
domains:
  # domain(s) to monitor
  watchlist: [domain.com]
  # any domains to ignore
  whitelist: []
  # domains created in the last week
  created_since: 168h

# send alerts to a Slack channel, optional
slack:
  # slack channel webhook
  webhook: https://hooks.slack.com/services/XXX

And then run the tool:

% dnstwist -config=config.yml

You can also set configuration values via environment variables:

% LOG_LEVEL=info DOMAIN_WATCHLIST=domain.com SLACK_WEBHOOK=xxx dnstwist

And use it with the Docker image!

% docker run -ti --rm -e "DOMAIN_WATCHLIST=domain.com" -e "SLACK_WEBHOOK=xxx" ghcr.io/hazcod/dnstwist/dnstwist:latest
