NTLMRecon : Enumerate Information From NTLM Authentication Enabled Web Endpoints

NTLMRecon is 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.

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
https://contoso.com/EWS/	XCORP	EXCHANGE01	xcorp.contoso.net	EXCHANGE01.xcorp.contoso.net	contoso.net

[–random-user-agent] [–force-all] [–shuffle] [-f]
optional arguments:
-h, –help show this help message and exit

Pass input as an IP address, URL or CIDR to enumerate
NTLM endpoints
–infile INFILE, -I 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, -O 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

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 takes actions accordingly. CIDR ranges are expanded by default (please note that there is no de-duplication baked in just yet!)

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
