NTLMRecon - A Tool To Enumerate Information From NTLM Authentication Enabled Web Endpoints

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.
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.

Demo

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.
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 :

URL Domain Name Server Name DNS Domain Name FQDN DNS Domain

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
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
