    Attacker's goals: An attacker is attempting to load an untrusted module into a trusted context to avoid detection, gain persistence or to perform privilege escalation.
    Investigative actions: Investigate the loaded module to verify if it is malicious. Investigate if the loading process and the loaded module reside in legitimate locations.
