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. -

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.

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.

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. .NOTES Author: Jared Atkinson (@jaredcatkinson) License: BSD 3-Clause Required Dependencies: PSReflect Optional Dependencies: None (func advapi32 ImpersonateLoggedOnUser ([bool]) @( [IntPtr] #_In_ HANDLE hToken ) -EntryPoint ImpersonateLoggedOnUser -SetLastError) .LINK https://msdn.microsoft.com/en-us/library/windows/desktop/aa378612(v=vs.85).aspx .EXAMPLE #> param ( [Parameter(Mandatory = $true)] [IntPtr] $TokenHandle ) $SUCCESS = $Advapi32::ImpersonateLoggedOnUser($TokenHandle); $LastError = [Runtime.InteropServices.Marshal]::GetLastWin32Error() if(-not $SUCCESS) { throw "ImpersonateLoggedOnUser Error: $(([ComponentModel.Win32Exception] $LastError).Message)" } } 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.
