reconDNS Tool For Cybersecurity professionals

recon

It was also developed with the aim of automating and facilitating the work of cybersecurity professionals.

Summary

reconDNS automates the entire process of reconnaisance for you. It outperforms the work of subdomain enumeration along with various vulnerability checks and obtaining maximum information about your target.

reconDNS uses lot of techniques (passive, bruteforce, permutations, certificate transparency, source code scraping, analytics, DNS records…) for subdomain enumeration which helps you getting the maximum and the most interesting subdomains so that you be ahead of the competition.

It also performs various vulnerability checks like XSSOpen RedirectsSSRFCRLFLFISQLiSSL testsSSTIDNS zone transfers, and much more. Along with these, it performs OSINT techniques, directory fuzzingdorkingports scanningscreenshotsnuclei scan on your target.

It was also developed with the aim of automating and facilitating the work of cybersecurity professionals.

So, what are you waiting for Go! 

Installation

a) In your PC/VPS/VM

You can check out our wiki for the installation guide Installation Guide

  • Requires Golang > 1.15.0+ installed and paths correctly set ($GOPATH$GOROOT)
git clone https://github.com/blackcode666/recondns.git
cd recondns/
chmod +x install.sh
./install.sh
./recondns.sh -d example.com -r

b) Docker Image (3 options)

  • Pull the image
$ docker pull blackcode666/recondns:main
  • Run the container
$ docker run -it --rm \
  -v "${PWD}/OutputFolder/":'/recondns/Recon/' \
  blackcode666/recondns:main -d example.com -r

However, if you wish to:

  1. Dynamically modify the behaviour & function of the image
  2. Build your own container
  3. Build an Axiom Controller on top of the official image

Please refer to the Docker documentation.

Config file:

A detailed explaintion of config file can be found here Configuration file 

  • Through recondns.cfg file the whole execution of the tool can be controlled.
  • Hunters can set various scanning modes, execution preferences, tools, config files, APIs/TOKENS, personalized wordlists and much more.

Usage:

Check out the wiki section to know which flag performs what all steps/attacks Usage Guide

TARGET OPTIONS

FlagDescription
-dSingle Target domain (example.com)
-lList of targets (one per line)
-mMultiple domain target (companyName)
-xExclude subdomains list (Out Of Scope)
-iInclude subdomains list (In Scope)

MODE OPTIONS

FlagDescription
-rRecon – Full recon process (without attacks like sqli,ssrf,xss,ssti,lfi etc.)
-sSubdomains – Perform only subdomain enumeration, web probing, subdomain takeovers
-pPassive – Perform only passive steps
-aAll – Perform whole recon and all active attacks
-wWeb – Perform only vulnerability checks/attacks on particular target
-nOSINT – Performs an OSINT scan (no subdomain enumeration and attacks)
-cCustom – Launches specific function against target
-hHelp – Show this help menu

GENERAL OPTIONS

FlagDescription
–deepDeep scan (Enable some slow options for deeper scan, vps intended mode)
-fCustom config file path
-oOutput directory
-vAxiom distributed VPS

Example Usage:

To perform a full recon on single target

./recondns.sh -d example.com -r

To perform a full recon on a list of targets

./recondns.sh -l sites.txt -r -o /output/directory/

Perform full recon with more time intense tasks (VPS intended only)

./recondns.sh -d example.com -r --deep -o /output/directory/

Perform recon in a multi domain target

./recondns.sh -m company -l domains_list.txt -r

Perform recon with axiom integration

./recondns.sh -d example.com -r -v

Perform all steps (whole recon + all attacks) a.k.a. YOLO mode

./recondns.sh -d example.com -a

Show help section

./recondns.sh -h

Axiom Support

axiom

Check out the wiki section for more info Axiom Support

  • As recondns actively hits the target with a lot of web traffic, hence there was a need to move to Axiom distributing the work load among various instances leading to reduction of execution time.
  • During the configuration of axiom you need to select recondns as provisoner.
  • You can create your own axiom’s fleet before running recondns or let recondns to create and destroy it automatically just modifying recondns.cfg file.

BBRF Support:

  • To add recondns results to your BBRF instance just add IP and credentials on recondns.cfg file section dedicated to bbrf.
  • During the execution of the scans the results will be added dinamically when each step ends.
  • Even you can set up locally your BBRF instance to be able to visualize your results in a fancy web UI.

Data Keep

Follow these simple steps to end up having a private repository with your API Keys and /Recon data.

  • Create a private blank repository on Git(Hub|Lab) (Take into account size limits regarding Recon data upload)
  • Clone your project: git clone https://gitlab.com/example/recondns-data
  • Get inside the cloned repository: cd recondns-data
  • Create branch with an empty commit: git commit --allow-empty -m "Empty commit"
  • Add official repo as a new remote: git remote add upstream https://github.com/blackcode666/recondns (upstream is an example)
  • Update upstream’s repo: git fetch upstream
  • Rebase current branch with the official one: git rebase upstream/main master

Main commands:

  • Upload changes to your personal repo: git add . && git commit -m "Data upload" && git push origin master
  • Update tool anytime: git fetch upstream && git rebase upstream/main master

How to contribute:

If you want to contribute to this project you can do it in multiple ways:

  • Submitting an issue because you have found a bug or you have any suggestion or request.
  • Making a Pull Request from dev branch because you want to improve the code or add something to the script.
