    Detects execution of the hacktool NetExec.
    NetExec (formerly CrackMapExec) is a widely used post-exploitation tool designed for Active Directory penetration testing and network enumeration
    In enterprise environments, the use of NetExec is considered suspicious or potentially malicious because it enables attackers to enumerate hosts, exploit network services, and move laterally across systems.
    Threat actors and red teams commonly use NetExec to identify vulnerable systems, harvest credentials, and execute commands remotely.

    Detects file creation events indicating NetExec (nxc.exe) execution on the local machine.
    NetExec is a PyInstaller-bundled binary that extracts its embedded data files to a "_MEI<random>" directory
    under the Temp folder upon execution. Files dropped under the "\nxc\" sub-directory of that
    extraction path are unique to NetExec and serve as reliable on-disk indicators of execution.
    NetExec (formerly CrackMapExec) is a widely used post-exploitation and lateral movement tool used for
    Active Directory enumeration, credential harvesting, and remote code execution.
