Netsh Helper DLL

Windowsnothing on this site yetT1546.007 on attack.mitre.org

Adversaries may establish persistence by executing malicious content triggered by Netsh Helper DLLs. Netsh.exe (also referred to as Netshell) is a command-line scripting utility used to interact with the network configuration of a system. It contains functionality to add helper DLLs for extending functionality of the utility. The paths to registered netsh.exe helper DLLs are entered into the Windows Registry at `HKLM\SOFTWARE\Microsoft\Netsh`.

how MITRE says to see it

Detection Strategy for Netsh Helper DLL Persistence via Registry and Child Process Monitoring (Windows)

Detection focuses on monitoring registry modifications under HKLM\SOFTWARE\Microsoft\Netsh that indicate the addition of helper DLLs, followed by anomalous child process activity or module load behavior initiated by netsh.exe.
