Takeover - SubDomain TakeOver Vulnerability Scanner

Sub-domain takeover vulnerability occur when a sub-domain (subdomain.example.com) is pointing to a service (e.g: GitHub, AWS/S3,..) that has been removed or deleted. This allows an attacker to set up a page on the service that was being used and point their page to that sub-domain. For example, if subdomain.example.com was pointing to a GitHub page and the user decided to delete their GitHub page, an attacker can now create a GitHub page, add a CNAME file containing subdomain.example.com, and claim subdomain.example.com.

Installation:

# git clone https://github.com/m4ll0k/takeover.git
# cd takeover
# python takeover.py

or:

PortWitness - Tool For Checking Whether A Domain Or Its Multiple Sub-Domains Are Up And Running

PortWitness is a bash tool designed to find out active domain and subdomains of websites using port scanning. It helps penetration testers and bug hunters collect and gather information about active subdomains for the domain they are targeting.PortWitness enumerates subdomains using Sublist3r and uses Nmap alongwith nslookup to check for active sites.Active domain or sub-domains are finally stored in an output file.Using that Output file a user can directly start testing those sites.

Sublist3r has also been integrated with this module.It's very effective and accurate when it comes to find out which sub-domains are active using Nmap and nslookup.

This tool also helps a user in getting the ip addresses of all sub-domains and stores then in a text file , these ip's can be used for further scanning of the target.

Installation

git clone https://github.com/viperbluff/PortWitness.git

BASH
This tool has been created using bash scripting so all you require is a linux machine.

Usage

bash portwitness.sh url

CloudFrunt - A Tool For Identifying Misconfigured CloudFront Domains

CloudFrunt is a tool for identifying misconfigured CloudFront domains.

Background

CloudFront is a Content Delivery Network (CDN) provided by Amazon Web Services (AWS). CloudFront users create "distributions" that serve content from specific sources (an S3 bucket, for example).

Each CloudFront distribution has a unique endpoint for users to point their DNS records to (ex. d111111abcdef8.cloudfront.net). All of the domains using a specific distribution need to be listed in the "Alternate Domain Names (CNAMEs)" field in the options for that distribution.

When a CloudFront endpoint receives a request, it does NOT automatically serve content from the corresponding distribution. Instead, CloudFront uses the HOST header of the request to determine which distribution to use. This means two things:

1. If the HOST header does not match an entry in the "Alternate Domain Names (CNAMEs)" field of the intended distribution, the request will fail.
   
2. Any other distribution that contains the specific domain in the HOST header will receive the request and respond to it normally.
   

This is what allows the domains to be hijacked. There are many cases where a CloudFront user fails to list all the necessary domains that might be received in the HOST header. For example:

• The domain "test.disloops.com" is a CNAME record that points to "disloops.com".
• The "disloops.com" domain is set up to use a CloudFront distribution.
• Because "test.disloops.com" was not added to the "Alternate Domain Names (CNAMEs)" field for the distribution, requests to "test.disloops.com" will fail.
• Another user can create a CloudFront distribution and add "test.disloops.com" to the "Alternate Domain Names (CNAMEs)" field to hijack the domain.

This means that the unique endpoint that CloudFront binds to a single distribution is effectively meaningless. A request to one specific CloudFront subdomain is not limited to the distribution it is associated with.

Installation

$ pip install boto3
$ pip install netaddr
$ pip install dnspython
$ git clone https://github.com/disloops/cloudfrunt.git
$ cd cloudfrunt
$ git clone https://github.com/darkoperator/dnsrecon.git

CloudFrunt expects the dnsrecon script to be cloned into a subdirectory called dnsrecon.

Usage

cloudfrunt.py [-h] [-l TARGET_FILE] [-d DOMAINS] [-o ORIGIN] [-i ORIGIN_ID] [-s] [-N]

-h, --help                      Show this message and exit
-s, --save                      Save the results to results.txt
-N, --no-dns                    Do not use dnsrecon to expand scope
-l, --target-file TARGET_FILE   File containing a list of domains (one per line)
-d, --domains DOMAINS           Comma-separated list of domains to scan
-o, --origin ORIGIN             Add vulnerable domains to new distributions with this origin
-i, --origin-id ORIGIN_ID       The origin ID to use with new distributions

Example

$ python cloudfrunt.py -o cloudfrunt.com.s3-website-us-east-1.amazonaws.com -i S3-cloudfrunt -l list.txt

SubOver - A Powerful Subdomain Takeover Tool

Subover is a Hostile Subdomain Takeover tool designed in Python. From start, it has been aimed with speed and efficiency in mind. Till date, SubOver detects 36 services which is much more than any other tool out there. The tool is multithreaded and hence delivers good speed. It can easily detect and report potential subdomain takeovers that exist. The list of potentially hijackable services is very comprehensive and it is what makes this tool so powerful.

Installing
You need to have Python 2.7 installed on your machine. The following additional requirements are required -

• dnspython
• colorama

git clone https://github.com/Ice3man543/SubOver.git .
cd SubOver
# consider installing virtualenv
pip install -r requirements.txt
python subover.py -h

Usage
python subover.py -l subdomains.txt -o output_takeovers.txt

• -l subdomains.txt is the list of target subdomains. These can be discovered using various tool such as sublist3r or others.
• -o output_takeovers.txtis the name of the output file. (Optional & Currently not very well formatted)
• -t 20 is the default number of threads that SubOver will use. (Optional)
• -V is the switch for showing verbose output. (Optional, Default=False)

FAQ
Q: What should my wordlist look like?
A: Your wordlist should include a list of subdomains you're checking and should look something like:

backend.example.com
something.someone.com
apo-setup.fxc.something.com

Your tool sucks!
Yes, you're probably correct. Feel free to:

• Not use it.
