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
- Process Hollowing
NOTE: Nothing in security is a silver bullet. An attacker could modify their tactics to avoid detection using this methodology.

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.

. 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
$hProcess = $Kernel32 ::OpenProcess( $DesiredAccess , $InheritHandle , $ProcessId ); $LastError = [ Runtime.InteropServices.Marshal ]::GetLastWin32Error()
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.

A valid handle to an open object.

When you are finished with the handle, be sure to close it using the CloseHandle function.

. SYNOPSIS
The OpenThreadToken function opens the access token associated with a thread
. DESCRIPTION
Tokens with the anonymous impersonation level cannot be opened.
Close the access token handle returned through the Handle parameter by calling CloseHandle.
. PARAMETER ThreadHandle
A handle to the thread whose access token is opened.
. PARAMETER DesiredAccess
Specifies an access mask that specifies the requested types of access to the access token. These requested access types are reconciled against the token's discretionary access control list (DACL) to determine which accesses are granted or denied.
. 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.

A handle to the process with memory that is being read. The handle must have PROCESS_VM_READ access to the process.
. PARAMETER BaseAddress
The base address in the specified process from which to read. Before any data transfer occurs, the system verifies that all data in the base address and memory of the specified size is accessible for read access, and if it is not accessible the function fails.
