NTLMRecon - A tool to enumerate information from NTLM authentication enabled web endpoints πŸ”Ž

NTLMRecon is built with flexibility 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.

A fast and flexible 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.

TODO

  1. Implement aiohttp based solution for sending requests
  2. Integrate a spraying library
  3. Add other authentication schemes found to the output
  4. Automatic detection of autodiscover domains if the domain

Overview of NTLMRecon

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

  1. AD Domain Name
  2. Server name
  3. DNS Domain Name
  4. FQDN
  5. 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.

On every successful discovery of a NTLM enabled web endpoint, the tool enumerates and saves information about the domain as follows to a CSV file :

Usage ofΒ NTLMRecon

ξ‚° $ ntlmrecon --help

             v.0.2 beta - Y'all still exposing NTLM endpoints?


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

optional 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
  --wordlist WORDLIST  Override the internal wordlist with a custom wordlist
  --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          Force enumerate all endpoints even if a valid endpoint is found for a URL (Default : False)
  --shuffle            Break order of the input files
  -f, --force          Force replace output file if it already exists

Example Usage

NTLMRecon 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

The tool 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
