Kerberos Ticket Granting Ticket Collection Script and Golden Ticket Detection Tests

Pass the Ticket (T1097)

Collection

Get-KerberosTicketGrantingTicket is a PowerShell script that queries each Logon Session for their associated Kerberos Ticket Granting Ticket. The output object contains information about the ticket itself, as well as, the Logon Session to which it belongs.

Detections

Test-KerberosTicketGrantingTicket is a script that provides a set of Unit Tests for "normal" Ticket Granting Ticket behavior. Below you will find a list of detections that are being used by the test script.

  • Logon Session User != Ticket Client
  • Ticket Lifetime != Expected Lifetime (Default 10 hours)
  • Ticket Renewal Length != Expected Renewal Length (Default 7 days)
  • Encryption Type != aes256_cts_hmac_sha1_96 (rc4 is common for inter-forest/domain tickets)
  • Session Authentication Package == (Kerberos || Negotiate)

Some of these detections are more behavior focused than others. For instance, a Golden Ticket made by Mimikatz with default arguments will have a 10 year Ticket Lifetime and Renewal Length, but Mimikatz also provides a command line option to set these values however the attacker pleases. Alternatively, a Logon Session should typically have a ticket for the user for whom the Logon Session belongs to.

I'd love to hear how accurate these detections are in production.

<#
.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 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 @{

function CloseHandle
{
<#
.SYNOPSIS
Closes an open object handle.
.DESCRIPTION
The CloseHandle function closes handles to the following objects:
- Access token
- Communications device
- Console input
- Console screen buffer
- Event
- File
- File mapping
- I/O completion port
- Job
- Mailslot
- Memory resource notification
- Mutex
- Named pipe
- Pipe
- Process
- Semaphore
- Thread
- Transaction
- Waitable timer
The documentation for the functions that create these objects indicates that CloseHandle should be used when you are finished with the object, and what happens to pending operations on the object after the handle is closed. In general, CloseHandle invalidates the specified object handle, decrements the object's handle count, and performs object retention checks. After the last handle to an object is closed, the object is removed from the system.
.PARAMETER Handle
A valid handle to an open object.

The DuplicateToken function creates an impersonation token, which you can use in functions such as SetThreadToken and ImpersonateLoggedOnUser. The token created by DuplicateToken cannot be used in the CreateProcessAsUser function, which requires a primary token. To create a token that you can pass to CreateProcessAsUser, use the DuplicateTokenEx function.
.PARAMETER TokenHandle
A handle to an access token opened with TOKEN_DUPLICATE access.
.PARAMETER ImpersonationLevel
Specifies a SECURITY_IMPERSONATION_LEVEL enumerated type that supplies the impersonation level of the new token. The Default is SecurityImpersonation.

function ImpersonateLoggedOnUser
{
<#
.SYNOPSIS
The ImpersonateLoggedOnUser function lets the calling thread impersonate the security context of a logged-on user. The user is represented by a token handle.
.DESCRIPTION
The impersonation lasts until the thread exits or until it calls RevertToSelf.
The calling thread does not need to have any particular privileges to call ImpersonateLoggedOnUser.
If the call to ImpersonateLoggedOnUser fails, the client connection is not impersonated and the client request is made in the security context of the process. If the process is running as a highly privileged account, such as LocalSystem, or as a member of an administrative group, the user may be able to perform actions they would otherwise be disallowed. Therefore, it is important to always check the return value of the call, and if it fails, raise an error; do not continue execution of the client request.
All impersonate functions, including ImpersonateLoggedOnUser allow the requested impersonation if one of the following is true:
- The requested impersonation level of the token is less than SecurityImpersonation, such as SecurityIdentification or SecurityAnonymous.
- The caller has the SeImpersonatePrivilege privilege.
- A process (or another process in the caller's logon session) created the token using explicit credentials through LogonUser or LsaLogonUser function.
- The authenticated identity is same as the caller.
Windows XP with SP1 and earlier: The SeImpersonatePrivilege privilege is not supported.
.PARAMETER TokenHandle
A handle to a primary or impersonation access token that represents a logged-on user. This can be a token handle returned by a call to LogonUser, CreateRestrictedToken, DuplicateToken, DuplicateTokenEx, OpenProcessToken, or OpenThreadToken functions. If hToken is a handle to a primary token, the token must have TOKEN_QUERY and TOKEN_DUPLICATE access. If hToken is a handle to an impersonation token, the token must have TOKEN_QUERY and TOKEN_IMPERSONATE access.

function LsaCallAuthenticationPackage
{
<#
.SYNOPSIS
The LsaCallAuthenticationPackage function is used by a logon application to communicate with an authentication package.
This function is typically used to access services provided by the authentication package.
.DESCRIPTION
Logon applications can call LsaCallAuthenticationPackage to communicate with an authentication package. There are several reasons why an application may do this:
- To implement multiple-message authentication protocols, such as the NTLM Challenge-Response protocol.
- To pass state change information to the authentication package. For example, the NTLM might notify the MSV1_0 package that a previously unreachable domain controller is now reachable. The authentication package would then re-logon any users logged on to that domain controller.
Typically, this function is used to exchange information with a custom authentication package. This function is not needed by an application that is using one of the authentication packages supplied with Windows, such as MSV1_0 or Kerberos.
You must call LsaCallAuthenticationPackage to clean up PKINIT device credentials for LOCAL_SYSTEM and NETWORK_SERVICE. When there is no PKINIT device credential, a successful call does no operation. When there is a PKINIT device credential, a successful call cleans up the PKINIT device credential so that only the password credential remains.

function LsaConnectUntrusted
{
<#
.SYNOPSIS
The LsaConnectUntrusted function establishes an untrusted connection to the LSA server.
.DESCRIPTION
LsaConnectUntrusted returns a handle to an untrusted connection; it does not verify any information about the caller. The handle should be closed using the LsaDeregisterLogonProcess function.
If your application simply needs to query information from authentication packages, you can use the handle returned by this function in calls to LsaCallAuthenticationPackage and LsaLookupAuthenticationPackage.
Applications with the SeTcbPrivilege privilege may create a trusted connection by calling LsaRegisterLogonProcess.

.SYNOPSIS
The RevertToSelf function terminates the impersonation of a client application.

A process should call the RevertToSelf function after finishing any impersonation begun by using the DdeImpersonateClient, ImpersonateDdeClientWindow, ImpersonateLoggedOnUser, ImpersonateNamedPipeClient, ImpersonateSelf, ImpersonateAnonymousToken or SetThreadToken function.
An RPC server that used the RpcImpersonateClient function to impersonate a client must call the RpcRevertToSelf or RpcRevertToSelfEx to end the impersonation.
If RevertToSelf fails, your application continues to run in the context of the client, which is not appropriate. You should shut down the process if RevertToSelf fails.
