# SharpWebServer
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
```powershell
:: 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 Banach / mgeeky, - combined all building blocks together,
added connection keep-alive to NTLM Authentication
Usage:
SharpWebServer.exe [dir=path] [verbose=true] [ntlm=true] [redir=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 how long should the server be running. Default: indefinitely
ntlm - Require NTLM Authentication before serving files. Useful to collect NetNTLM hashes
(in MDSec's Farmer style)
redir - Redirect after NTLM authentication based on redir paramerer in the url (e.g. ?redir=https://example.com)
logfile - Path to output logfile.
```
## Example
Example use-case serving files and capturing Net-NTLM hashes at the same time:
**Server**:
```powershell
C:\> SharpWebServer.exe port=8888 dir=C:\Windows\Temp verbose=true ntlm=true
:: SharpWebServer ::

[.] Serving HTTP server on port : 8888
[.] Will run for this long : 60 seconds
[.] Verbose mode turned on.
[.] NTLM mode turned on.
[.] Serving files from directory : C:\Windows\Temp
