NTLMRecon

A fast NTLM reconnaissance tool without external dependencies. Useful to find out information about NTLM endpoints when working with a large set of potential IP addresses and domains.

Work in Progess. Things may break and change often.

NTLMRecon is built with flexibilty in mind. Need to run recon on a single URL, an IP address, an entire CIDR range or combination of all of it all put in a single input file? No problem! NTLMRecon got you covered. Read on.

Internal wordlists are from the awesome nyxgeek/lyncsmash repo

Overview

NTLMRecon looks for NTLM enabled web endpoints, sends a fake authentication request and enumerates the following information from the NTLMSSP response:

AD Domain Name
Server name
DNS Domain Name
FQDN
Parent DNS Domain

Since ntlmrecon leverages a python implementation of NTLMSSP, it eliminates the overhead of running Nmap NSE http-ntlm-info for every successful discovery.

Getting Started

Clone the repository - git clone https://github.com/sachinkamath/ntlmrecon/
RECOMMENDED - Install virtualenv pip install virtualenv
Start a new virtual environment - virtualenv venv and activate it with source venv/bin/activate
Run the setup file - python setup.py install
Run ntlmrecon - ntlmrecon --help

Usage

usage: ntlmrecon [-h] [--input INPUT | --infile INFILE] [--threads THREADS] [--output-type] --outfile OUTFILE [--random-user-agent] [--force-all] [--shuffle]

Arguments:
  -h, --help           show this help message and exit
  --input INPUT        Pass input as an IP address, URL or CIDR to enumerate NTLM endpoints
  --infile INFILE       Pass input from a local file
  --threads THREADS    Set number of threads (Default: 10)
  --output-type, -o    Set output type. JSON (TODO) and CSV supported (Default: CSV)
  --outfile OUTFILE     Set output file name (Default: ntlmrecon.csv)
  --random-user-agent  TODO: Randomize user agents when sending requests (Default: False)
  --force-all          TODO: Force enumerate all endpoints even if a valid endpoint is found for a URL (Default : False)
  --shuffle              Break order of the input files (TODO: Improve logic)

Example Usage

Recon on a single URL

$ ntlmrecon --input https://mail.contoso.com --outfile ntlmrecon.csv

Recon on a CIDR range or IP address

$ ntlmrecon --input 192.168.1.1/24 --outfile ntlmrecon-ranges.csv

Recon on an input file

NTLM recon automatically detects the type of input per line and gives you results automatically. CIDR ranges are expanded automatically even when read from a text file.

Input file can be something as mixed up as :

mail.contoso.com
CONTOSOHOSTNAME
10.0.13.2/28
192.168.222.1/24
https://mail.contoso.com

To run recon with an input file, just run :

$ ntlmrecon --infile /path/to/input/file --outfile ntlmrecon-fromfile.csv
