.DESCRIPTION
A compilation of multiple system enumeration / situational awareness techniques collected over time.
If system is a member of a domain, it can perform additional enumeration. However, the included domain enumeration is limited with the intention that PowerView, BoodHound, etc will be also be used.
Report HTML file is written in the format of YYYYMMDD_HHMMSS_HOSTNAME.html in the current working directory.
Invoke-HostEnum is Powershell 2.0 compatible to ensure it functions on the widest variety of Windows targets
Enumerated Information:
- OS Details, Hostname, Uptime, Installdate
- Installed Applications and Patches
- Network Adapter Configuration, Network Shares, Listening Ports, Connections, Routing Table, DNS Cache, Firewall Status
- Running Processes and Installed Services
- Interesting Registry Entries
- Local Users, Groups, Administrators
- Personal Security Product Status, AV Processes
- Interesting file locations and keyword searches via file indexing
- Interesting Windows Logs (User logins)
- Basic Domain enumeration (users, groups, trusts, domain controllers, account policy, SPNs)
.PARAMETER All
Executes Local, Domain, and Privesc functions
.PARAMETER Local
Executes the local enumeration functions
.PARAMETER Domain
Executes the domain enumeration functions
.PARAMETER Privesc
Executes modified version of PowerUp privilege escalation enumeration (Invoke-AllChecks)
.PARAMETER Quick
Executes a brief initial survey that may be useful when initially accessing a host
Only enumerates basic system info, processes, av, network adapters, firewall state, network connections, users, and groups
Note: Not usable with -HTMLReport
.PARAMETER HTMLReport
Creates an HTML Report of enumeration results
.PARAMETER Verbose
Enables verbosity (Leverages Write-Verbose and output may differ depending on the console/agent you're using)
.EXAMPLE
PS C:\> Invoke-HostEnum -Local -HTMLReport -Verbose
Performs local system enumeration with verbosity and writes output to a HTML report
.EXAMPLE
PS C:\> Invoke-HostEnum -Domain -HTMLReport
Performs domain enumeration using net commands and saves the output to the current directory
.EXAMPLE
PS C:\> Invoke-HostEnum -Local -Domain
Performs local and domain enumeration functions and outputs the results to the console

<#
.SYNOPSIS
This script is used to get useful information from a computer.
Function: Get-ComputerDetails
Author: Joe Bialek, Twitter: @JosephBialek
Required Dependencies: None
Optional Dependencies: None
.DESCRIPTION
This script is used to get useful information from a computer. Currently, the script gets the following information:
-Explicit Credential Logons (Event ID 4648)
-Logon events (Event ID 4624)
-AppLocker logs to find what processes are created
-PowerShell logs to find PowerShell scripts which have been executed
-RDP Client Saved Servers, which indicates what servers the user typically RDP's in to
.PARAMETER ToString
Switch: Outputs the data as text instead of objects, good if you are using this script through a backdoor.
.EXAMPLE
Get-ComputerDetails
Gets information about the computer and outputs it as PowerShell objects.
Get-ComputerDetails -ToString
Gets information about the computer and outputs it as raw text.
.NOTES
This script is useful for fingerprinting a server to see who connects to this server (from where), and where users on this server connect to.
You can also use it to find Powershell scripts and executables which are typically run, and then use this to backdoor those files.

Specifies the desired name for the in-memory assembly and module. If
ModuleName is not provided, it will default to a GUID.

{
<#
.SYNOPSIS
Creates a .NET type for an unmanaged Win32 function.
Author: Matthew Graeber (@mattifestation)
License: BSD 3-Clause
Required Dependencies: None
Optional Dependencies: func
.DESCRIPTION
Add-Win32Type enables you to easily interact with unmanaged (i.e.
Win32 unmanaged) functions in PowerShell. After providing
Add-Win32Type with a function signature, a .NET type is created
using reflection (i.e. csc.exe is never called like with Add-Type).
The 'func' helper function can be used to reduce typing when defining
multiple function definitions.
.PARAMETER DllName
The name of the DLL.
.PARAMETER FunctionName
The name of the target function.
.PARAMETER EntryPoint
The DLL export function name. This argument should be specified if the
specified function name is different than the name of the exported
function.
.PARAMETER ReturnType
The return type of the function.
.PARAMETER ParameterTypes
The function parameters.
.PARAMETER NativeCallingConvention
Specifies the native calling convention of the function. Defaults to
stdcall.
.PARAMETER Charset
If you need to explicitly call an 'A' or 'W' Win32 function, you can
specify the character set.
.PARAMETER SetLastError
Indicates whether the callee calls the SetLastError Win32 API
function before returning from the attributed method.
.PARAMETER Module
The in-memory module that will host the functions. Use
New-InMemoryModule to define an in-memory module.
.PARAMETER Namespace
An optional namespace to prepend to the type. Add-Win32Type defaults
to a namespace consisting only of the name of the DLL.
.EXAMPLE
$Mod = New-InMemoryModule -ModuleName Win32
$FunctionDefinitions = @(
(func kernel32 GetProcAddress ([IntPtr]) @([IntPtr], [String]) -Charset Ansi -SetLastError),
(func kernel32 GetModuleHandle ([Intptr]) @([String]) -SetLastError),
(func ntdll RtlGetCurrentPeb ([IntPtr]) @())
)
$Types = $FunctionDefinitions | Add-Win32Type -Module $Mod -Namespace 'Win32'
$Kernel32 = $Types['kernel32']
$Ntdll = $Types['ntdll']
$Ntdll::RtlGetCurrentPeb()
$ntdllbase = $Kernel32::GetModuleHandle('ntdll')
$Kernel32::GetProcAddress($ntdllbase, 'RtlGetCurrentPeb')
.NOTES
Inspired by Lee Holmes' Invoke-WindowsApi http://poshcode.org/2189
When defining multiple function prototypes, it is ideal to provide
Add-Win32Type with an array of function signatures. That way, they
are all incorporated into the same in-memory module.

<#
.SYNOPSIS
Creates an in-memory enumeration for use in your PowerShell session.
Author: Matthew Graeber (@mattifestation)
License: BSD 3-Clause
Required Dependencies: None
Optional Dependencies: None
.DESCRIPTION
The 'psenum' function facilitates the creation of enums entirely in
memory using as close to a "C style" as PowerShell will allow.
.PARAMETER Module
The in-memory module that will host the enum. Use
New-InMemoryModule to define an in-memory module.
.PARAMETER FullName
The fully-qualified name of the enum.
.PARAMETER Type
The type of each enum element.
.PARAMETER EnumElements
A hashtable of enum elements.
.PARAMETER Bitfield
Specifies that the enum should be treated as a bitfield.
.EXAMPLE
$Mod = New-InMemoryModule -ModuleName Win32
$ImageSubsystem = psenum $Mod PE.IMAGE_SUBSYSTEM UInt16 @{
UNKNOWN = 0
NATIVE = 1 # Image doesn't require a subsystem.
WINDOWS_GUI = 2 # Image runs in the Windows GUI subsystem.
WINDOWS_CUI = 3 # Image runs in the Windows character subsystem.
OS2_CUI = 5 # Image runs in the OS/2 character subsystem.
POSIX_CUI = 7 # Image runs in the Posix character subsystem.
NATIVE_WINDOWS = 8 # Image is a native Win9x driver.
WINDOWS_CE_GUI = 9 # Image runs in the Windows CE subsystem.
EFI_APPLICATION = 10
EFI_BOOT_SERVICE_DRIVER = 11
EFI_RUNTIME_DRIVER = 12
EFI_ROM = 13
XBOX = 14
WINDOWS_BOOT_APPLICATION = 16
}
.NOTES
PowerShell purists may disagree with the naming of this function but
again, this was developed in such a way so as to emulate a "C style"
definition as closely as possible. Sorry, I'm not going to name it
New-Enum. :P

<#
.SYNOPSIS
Creates an in-memory struct for use in your PowerShell session.
Author: Matthew Graeber (@mattifestation)
License: BSD 3-Clause
Required Dependencies: None
Optional Dependencies: field
.DESCRIPTION
The 'struct' function facilitates the creation of structs entirely in
memory using as close to a "C style" as PowerShell will allow. Struct
fields are specified using a hashtable where each field of the struct
is comprosed of the order in which it should be defined, its .NET
type, and optionally, its offset and special marshaling attributes.
One of the features of 'struct' is that after your struct is defined,
it will come with a built-in GetSize method as well as an explicit
converter so that you can easily cast an IntPtr to the struct without
relying upon calling SizeOf and/or PtrToStructure in the Marshal
class.
.PARAMETER Module
The in-memory module that will host the struct. Use
New-InMemoryModule to define an in-memory module.
.PARAMETER FullName
The fully-qualified name of the struct.
.PARAMETER StructFields
A hashtable of fields. Use the 'field' helper function to ease
defining each field.
.PARAMETER PackingSize
Specifies the memory alignment of fields.
.PARAMETER ExplicitLayout
Indicates that an explicit offset for each field will be specified.
.EXAMPLE
$Mod = New-InMemoryModule -ModuleName Win32
$ImageDosSignature = psenum $Mod PE.IMAGE_DOS_SIGNATURE UInt16 @{
DOS_SIGNATURE = 0x5A4D
OS2_SIGNATURE = 0x454E
OS2_SIGNATURE_LE = 0x454C
VXD_SIGNATURE = 0x454C
}
$ImageDosHeader = struct $Mod PE.IMAGE_DOS_HEADER @{
e_magic = field 0 $ImageDosSignature
e_cblp = field 1 UInt16
e_cp = field 2 UInt16
e_crlc = field 3 UInt16
e_cparhdr = field 4 UInt16
e_minalloc = field 5 UInt16
e_maxalloc = field 6 UInt16
e_ss = field 7 UInt16
e_sp = field 8 UInt16
e_csum = field 9 UInt16
e_ip = field 10 UInt16
e_cs = field 11 UInt16
e_lfarlc = field 12 UInt16
e_ovno = field 13 UInt16
e_res = field 14 UInt16[] -MarshalAs @('ByValArray', 4)
e_oemid = field 15 UInt16
e_oeminfo = field 16 UInt16
e_res2 = field 17 UInt16[] -MarshalAs @('ByValArray', 10)
e_lfanew = field 18 Int32
}
# Example of using an explicit layout in order to create a union.
$TestUnion = struct $Mod TestUnion @{
field1 = field 0 UInt32 0
field2 = field 1 IntPtr 0
} -ExplicitLayout
.NOTES
PowerShell purists may disagree with the naming of this function but
again, this was developed in such a way so as to emulate a "C style"
definition as closely as possible. Sorry, I'm not going to name it
New-Struct. :P

.SYNOPSIS
Parses a passed string containing multiple possible file/folder paths and returns
the file paths where the current user has modification rights.
Author: @harmj0y
License: BSD 3-Clause
.DESCRIPTION
Takes a complex path specification of an initial file/folder path with possible
configuration files, 'tokenizes' the string in a number of possible ways, and
enumerates the ACLs for each path that currently exists on the system. Any path that
the current user has modification rights on is returned in a custom object that contains
the modifiable path, associated permission set, and the IdentityReference with the specified
rights. The SID of the current user and any group he/she are a part of are used as the
comparison set against the parsed path DACLs.
.PARAMETER Path
The string path to parse for modifiable files. Required
.PARAMETER LiteralPaths
Switch. Treat all paths as literal (i.e. don't do 'tokenization').
.EXAMPLE
PS C:\> '"C:\Temp\blah.exe" -f "C:\Temp\config.ini"' | Get-ModifiablePath

---- ----------- -----------------
C:\Temp\blah.exe {ReadAttributes, ReadCo... NT AUTHORITY\Authentic...

.SYNOPSIS
Returns all SIDs that the current user is a part of, whether they are disabled or not.
Author: @harmj0y
License: BSD 3-Clause
.DESCRIPTION
First gets the current process handle using the GetCurrentProcess() Win32 API call and feeds
this to OpenProcessToken() to open up a handle to the current process token. The API call
GetTokenInformation() is then used to enumerate the TOKEN_GROUPS for the current process
token. Each group is iterated through and the SID structure is converted to a readable
string using ConvertSidToStringSid(), and the unique list of SIDs the user is a part of
(disabled or not) is returned as a string array.

QueryServiceObjectSecurity to retrieve a copy of the security descriptor for the service.
.PARAMETER Name
An array of one or more service names to add a service Dacl for. Passable on the pipeline.
.EXAMPLE
PS C:\> Get-Service | Add-ServiceDacl
Add Dacls for every service the current user can read.
.EXAMPLE
PS C:\> Get-Service -Name VMTools | Add-ServiceDacl
Add the Dacl to the VMTools service object.

from the applicationHost.config file on the system. The output supports the
pipeline which can be used to convert all of the results into a pretty table by piping
to format-table.
.EXAMPLE
Return application pool and virtual directory passwords from the applicationHost.config on the system.
PS C:\> Get-ApplicationHost
user : PoolUser1
pass : PoolParty1!
type : Application Pool
vdir : NA
apppool : ApplicationPool1
user : PoolUser2
pass : PoolParty2!
type : Application Pool
vdir : NA
apppool : ApplicationPool2
user : VdirUser1
pass : VdirPassword1!
type : Virtual Directory
vdir : site1/vdir1/
apppool : NA
user : VdirUser2
pass : VdirPassword2!
type : Virtual Directory
vdir : site2/
apppool : NA
.EXAMPLE
Return a list of cleartext and decrypted connect strings from web.config files.
PS C:\> Get-ApplicationHost | Format-Table -Autosize
user pass type vdir apppool
---- ---- ---- ---- -------
PoolUser1 PoolParty1! Application Pool NA ApplicationPool1
PoolUser2 PoolParty2! Application Pool NA ApplicationPool2
VdirUser1 VdirPassword1! Virtual Directory site1/vdir1/ NA
VdirUser2 VdirPassword2! Virtual Directory site2/ NA

.SYNOPSIS
Retrieves the plaintext passwords for found McAfee's SiteList.xml files.
Based on Jerome Nokin (@funoverip)'s Python solution (in links).
PowerSploit Function: Get-SiteListPassword
Original Author: Jerome Nokin (@funoverip)
PowerShell Port: @harmj0y
License: BSD 3-Clause
Required Dependencies: None
Optional Dependencies: None
.DESCRIPTION
Searches for any McAfee SiteList.xml in C:\Program Files\, C:\Program Files (x86)\,
C:\Documents and Settings\, or C:\Users\. For any files found, the appropriate
credential fields are extracted and decrypted using the internal Get-DecryptedSitelistPassword
function that takes advantage of McAfee's static key encryption. Any decrypted credentials
are output in custom objects. See links for more information.
.PARAMETER Path
Optional path to a SiteList.xml file or folder.
