Look for abuse contacts for IP, domain names, email addresses and URLs.

pip install abuse-finder==0.2



Python library to help automatically find the most appropriate contact for abuse reports. Supports Python2.7 and Python3.6

Currently supports the following types of observables:

  • Hostnames
  • IP addresses
  • URLs
  • Email addresses


You can install this using pip:

$ pip install abuse_finder

Or from the source code:

$ git clone https://github.com/certsocietegenerale/abuse_finder.git
$ cd abuse_finder
$ python setup.py install


This library provides a function for each kind of supported observable: domain_abuse, ip_abuse, url_abuse and email_abuse.

All functions are similar, they are taking a single argument, which is a string containing the observable's value, and return a dict containing the following elements:

  • value: value of the observable
  • names: a list of guesses for the names of the organizations that should be contacted to report abuse
  • abuse: a list of guesses of email addresses to contact to report abuse
  • raw: raw data containing information used to make theses guesses (whois / network whois)

For hostnames, a WHOIS request will be performed and parsed using pythonwhois. The name of the registrar will be returned, as well as the email address referenced for abuse reports if any.

IP Addresses

For IP addresses, a network WHOIS is performed and parsed using ipwhois.

The names are determined by using the description field of the parsed nets. The smallest net comes first.

The email addresses are determined by counting the references to abuse on each line containing email addresses.


When using URLs:

  1. First, the URL is parsed in order to extract the registered domain, or an IP address
  2. In case of a domain, a DNS request is made in order to get IP addresses matching with the registered domain
  3. A lookup is made for every IP address, and the results are combined

Email addresses

When using email addresses:

  1. First, a domain lookup is made, but this time looking for an abuse contact provided by the registrant (looking for 'abuse' in provided email addresses).
  2. If no contact was found, do the same for every domain present in MX records.
