| function Get-InjectedThread | |
| { | |
| <# | |
| .SYNOPSIS | |
| Looks for threads that were created as a result of code injection. | |
| .DESCRIPTION | |
| Memory resident malware (fileless malware) often uses a form of memory injection to get code execution. Get-InjectedThread looks at each running thread to determine if it is the result of memory injection. | |
| Common memory injection techniques that *can* be caught using this method include: | |
| - Classic Injection (OpenProcess, VirtualAllocEx, WriteProcessMemory, CreateRemoteThread) | |
| - Reflective DLL Injection | |
| - Memory Module | |
| NOTE: Nothing in security is a silver bullet. An attacker could modify their tactics to avoid detection using this methodology. | |

| function Add-Win32Type | |

| <# | |
| .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. | |

| 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 | |

| 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_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 | |

| 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. | |

| .SYNOPSIS | |
| Opens an existing local process object. | |

| To open a handle to another local process and obtain full access rights, you must enable the SeDebugPrivilege privilege. | |
| The handle returned by the OpenProcess function can be used in any function that requires a handle to a process, such as the wait functions, provided the appropriate access rights were requested. | |
| When you are finished with the handle, be sure to close it using the CloseHandle function. | |
| .PARAMETER ProcessId | |
| The identifier of the local process to be opened. | |
| If the specified process is the System Process (0x00000000), the function fails and the last error code is ERROR_INVALID_PARAMETER. If the specified process is the Idle process or one of the CSRSS processes, this function fails and the last error code is ERROR_ACCESS_DENIED because their access restrictions prevent user-level code from opening them. | |
| .PARAMETER DesiredAccess | |
| The access to the process object. This access right is checked against the security descriptor for the process. This parameter can be one or more of the process access rights. | |
| If the caller has enabled the SeDebugPrivilege privilege, the requested access is granted regardless of the contents of the security descriptor. | |
| .PARAMETER InheritHandle | |
| If this value is TRUE, processes created by this process will inherit the handle. Otherwise, the processes do not inherit this handle. | |

| .PARAMETER ThreadHandle | |
| A handle to the thread whose access token is opened. | |

| .PARAMETER OpenAsSelf | |
| TRUE if the access check is to be made against the process-level security context. | |
| FALSE if the access check is to be made against the current security context of the thread calling the OpenThreadToken function. | |
| The OpenAsSelf parameter allows the caller of this function to open the access token of a specified thread when the caller is impersonating a token at SecurityIdentification level. Without this parameter, the calling thread cannot open the access token on the specified thread because it is impossible to open executive-level objects by using the SecurityIdentification impersonation level. | |

| <# | |
| .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. | |

| 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 | |

| function Stop-Thread | |
| { | |
| <# | |
| .SYNOPSIS | |
| Terminates a specified Thread. | |
| .DESCRIPTION | |
| The Stop-Thread function can stop an individual thread in a process. This is quite useful in situations where code injection (dll injection) techniques have been used by attackers. If an attacker runs their malicious code in a thread within a critical process, then Stop-Thread can kill the malicious thread without hurting the critical process. | |

| function Add-Win32Type | |
| { | |
| <# | |
| .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. | |

| 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 | |

| 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. | |

| function OpenThread | |
| { | |
| <# | |
| .SYNOPSIS | |
| Opens an existing thread object. | |
| .DESCRIPTION | |
| The handle returned by OpenThread can be used in any function that requires a handle to a thread, such as the wait functions, provided you requested the appropriate access rights. The handle is granted access to the thread object only to the extent it was specified in the dwDesiredAccess parameter. | |
| When you are finished with the handle, be sure to close it by using the CloseHandle function. | |
| .PARAMETER ThreadId | |
| The identifier of the thread to be opened. | |
| .PARAMETER DesiredAccess | |
| The access to the thread object. This access right is checked against the security descriptor for the thread. This parameter can be one or more of the thread access rights. | |
| If the caller has enabled the SeDebugPrivilege privilege, the requested access is granted regardless of the contents of the security descriptor. | |
| .PARAMETER InheritHandle | |
| If this value is TRUE, processes created by this process will inherit the handle. Otherwise, the processes do not inherit this handle. | |

| function TerminateThread | |
| { | |
| <# | |
| .SYNOPSIS | |
| Terminates a thread. | |
| .DESCRIPTION | |
| TerminateThread is used to cause a thread to exit. When this occurs, the target thread has no chance to execute any user-mode code. DLLs attached to the thread are not notified that the thread is terminating. The system frees the thread's initial stack. | |
| .PARAMETER ThreadHandle | |
| A handle to the thread to be terminated. | |
| The handle must have the THREAD_TERMINATE access right. | |
| .PARAMETER ExitCode | |
| The exit code for the thread. This thread's exit code will be set to this value upon termination. | |
