Description

A Red Team oriented simple HTTP & WebDAV server written in C# with functionality to capture Net-NTLM hashes. To be used for serving payloads on compromised machines for lateral movement purposes.

Requires .NET Framework 4.5 and _ System.Net _ and _ System.Net.Sockets _ references.

Usage

    :: SharpWebServer ::  
    a Red Team oriented C# Simple HTTP Server with Net-NTLMv1/2 hashes capture functionality

Authors:  
    - Can Güney Aksakalli (github.com/aksakalli)          - original implementation  
    - harrypatrick442 (github.com/harrypatrick442)        - aksakalli's fork & changes  
    - Dominic Chell (@domchell) from MDSec                - Net-NTLMv2 hashes capture code borrowed from Farmer  
    - Mariusz B. / mgeeky, &lt;mb [at] binary-offensive.com&gt; - combined all building blocks together,  
                                                            added connection keep-alive to NTLM Authentication

Usage:  
    SharpWebServer.exe &lt;port=port&gt; [dir=path] [verbose=true] [ntlm=true] [logfile=path]

Options:  
    port    - TCP Port number on which to listen (1-65535)  
    dir     - Directory with files to be hosted.  
    verbose - Turn verbose mode on.  
    seconds - Specifies h   ow long should the server be running. Default: indefinitely  
    ntlm    - Require NTLM Authentication before serving files. Useful to collect NetNTLMv2 hashes  
              (in MDSec's Farmer style)  
    logfile - Path to output logfile.

Example

Example use-case serving files and capturing Net-NTLM hashes at the same time:
