This analytic detects PowerShell code that uses P/Invoke to call Windows API functions associated with process injection, such as VirtualAlloc, WriteProcessMemory, and CreateRemoteThread, indicating potential malicious activity.

This brief details detection of PowerShell scripts leveraging P/Invoke API calls to perform process injection, covering techniques like self-injection, remote thread injection, APC injection, thread-context hijacking, process hollowing, section-map injection, reflective DLL loading, and DLL injection.
