assetfinder is a Go-based tool to find related domains and subdomains that are potentially related to a given domain from a variety of sources including Facebook, ThreatCrowd, Virustotal and more.

assetfinder uses a variety of sources including those in the infosec space and social networks which can give relevant info:

• crt.sh
• certspotter
• hackertarget
• threatcrowd
• wayback machine
• dns.bufferover.run
• facebook – Needs FB_APP_ID and FB_APP_SECRET environment variables set (https://developers.facebook.com/) and you need to be careful with your app’s rate limits
• virustotal – Needs VT_API_KEY environment variable set (https://developers.virustotal.com/reference)
• findsubdomains – Needs SPYSE_API_TOKEN environment variable set (the free version always gives the first response page, and you also get “25 unlimited requests”) — (https://spyse.com/apidocs)

Sources to be implemented:

• http://api.passivetotal.org/api/docs/
• https://community.riskiq.com/ (?)
• https://riddler.io/
• http://www.dnsdb.org/
• https://certdb.com/api-documentation

Usage of assetfinder to Find Related Domains and Subdomains

The usage is very simple with only one option basically, to limit the search to subdomains only – by default it will scan for all associated domains and subdomains.

Installing assetfinder to Find Related Domains and Subdomains

If you have Go installed and configured (i.e. with $GOPATH/bin in your $PATH):

Another similar and recent tool that uses many of these sources and more and is also worth checking out is The OWASP Amass Project- DNS Enumeration, Attack Surface Mapping & External Asset Discovery.

Karkinos is a light-weight Beginner Friendly Penetration Testing Tool, which is basically a ‘Swiss Army Knife’ for pen-testing and/or hacking CTF’s.

Karkinos Beginner Friendly Penetration Testing Tool Features

• Encoding/Decoding characters
• Encrypting/Decrypting text or files
• Reverse shell handling
• Cracking and generating hashes

How to Install Karkinos Beginner Friendly Penetration Testing Tool

Dependencies are:

• Any server capable of hosting PHP
• Tested with PHP 7.4.9
• Tested with Python 3.8
• Make sure it is in your path as:
• Windows: python
• Linux: python3
• If it is not, please change the commands in includes/pid.php
• Pip3
• Raspberry Pi Zero friendly :) (crack hashes at your own risk)

Then:

1. git clone https://github.com/helich0pper/Karkinos.git
2. cd Karkinos
3. pip3 install -r requirements.txt
4. cd wordlists && unzip passlist.zip You can also unzip it manually using file explorer. Just make sure passlist.txt is in wordlists directory.
5. Make sure you have write privilages for db/main.db
6. Enable extension=mysqli in your php.ini file.
7. If you don’t know where to find this, refer to the PHP docs. Note: MySQLi is only used to store statistics.
8. Thats it! Now just host it using your preferred web server or run: php -S 127.0.0.1:8888 in the Karkinos directory.

Important: using port 5555, 5556, or 5557 will conflict with the Modules
If you insist on using these ports, change the PORT value in:

• /bin/Server/app.py Line 87
• /bin/Busting/app.py Line 155
• /bin/PortScan/app.py Line 128

Aclpwn.py is a tool that interacts with BloodHound to identify and exploit ACL based privilege escalation paths.

It takes a starting and ending point and will use Neo4j pathfinding algorithms to find the most efficient ACL based privilege escalation path.

Features of Aclpwn.Py Exploit ACL Based Privilege Escalation Paths in Active Directory

Aclpwn.Py currently has the following features:

• Direct integration with BloodHound and the Neo4j graph database (fast pathfinding)
• Supports any reversible ACL based attack chain (no support for resetting user passwords right now)
• Advanced pathfinding (Dijkstra) to find the most efficient paths
• Support for exploitation with NTLM hashes (pass-the-hash)
• Saves restore state, easy rollback of changes
• Can be run via a SOCKS tunnel
• Written in Python (2.7 and 3.5+), so OS independent

Installation of Aclpwn.py ACL Based Privilege Escalation

Aclpwn.py is compatible with both Python 2.7 and 3.5+. It requires the neo4j-driver, impacket and ldap3 libraries. You can install aclpwn.py via pip: pip install aclpwn. For Python 3, you will need the python36 branch of impacket since the master branch (and versions published on PyPI) are Python 2 only at this point.

This tool does not exploit any vulnerabilities, but relies on misconfigured (often because of delegated privileges) or insecure default ACLs. To solve these issues, it is important to identify potentially dangerous ACLs in your Active Directory environment with BloodHound. For detection, Windows Event Logs can be used.
