MYRA RAT systemd-userdbd Process Name Masquerade Detection

Detects instances of the systemd-userdbd process executing from non-standard file paths or general systemd-related processes launching from world-writable or temporary directories (e.g., /tmp, /dev/shm, /var/tmp, /home). This behavior is often indicative of process masquerading or a persistence mechanism where an adversary attempts to execute a malicious binary by mimicking system service naming conventions.
