What it detects

This rule detects the auto-elevating binary easinvoker.exe loading a netutils.dll from outside System32, the DLL hijacking and UAC bypass chain DBatLoader uses to run malicious code with elevated privileges. Adversaries place the legitimate signed executable alongside a rogue netutils.dll to inherit auto-elevation, making early detection critical for catching privilege escalation before injection into SndVol.exe or iexpress.exe.
