Some helper subdomain_takeover_tools to validate subdomain takeovers

Subdomain Takeover Tools

A set of tools to validate the initial outcome of subtake.

Installation

1. Install using pip:

   pip install subdomain_takeover_tools

   for windows:

   py -m pip install subdomain_takeover_tools

   Alternatively, you can download or clone this repo and call pip install -e ..

Confirming takeovers

All scripts support the following two parameters:

• --strict: only report as vulnerable if the issue is not also applicable on hostname.tld and www.hostname.tld.
• --inverse: do inverse reporting, so report all subdomains that are not vulnerable

Confirming S3

Subtake has some false positives on Google Cloud buckets as S3 buckets, also some access denied's end up in the results.

The script confirm-s3.py will make sure that the bucket is actually vulnerable.

grep "\[s3 bucket: " subtake-output.txt | confirm_s3

Confirming ELB

Some patterns of elb are vulnerable while others are not, to filter them we can use our script:

grep "\[elasticbeanstalk: " subtake-output.txt | confirm_elb

Note: the parameter --strict is accepted here but will not lead to expected results.

Confirming Shopify

It seems that

grep "\[shopify: " subtake-output.txt | confirm_shopify

Separate tools

Extracting domain names

As part of my process I want to know the domains involved in my findings.

Example usage:

cut -f3 < subtake-output.txt | extract_domain_names | sort -u > involved.domains

Note that extract_domain_names also support groups, such as domain.(co.id|in.th|ph|vn), this will be expanded automatically.
