Detects DLLs loading from a spoofed Windows directory path with an extra space (e.g "C:\Windows \System32") which can bypass Windows trusted path verification.
This technique tricks Windows into treating the path as trusted, allowing malicious DLLs to load with high integrity privileges bypassing UAC.

Detects potentially suspicious subprocesses such as LOLBINs spawned by web browsers. This activity could be associated with the "FileFix" social engineering technique,
where users are tricked into launching the file explorer via a browser-based phishing page and pasting malicious commands into the address bar.
The technique abuses clipboard manipulation and disguises command execution as benign file path access, resulting in covert execution of system utilities.
