What it detects

This rule detects cmd.exe creating a directory junction with mklink /D, the filesystem redirection RONINGLOADER uses to stage a fake roming directory during its PPL abuse chain. Directory junctions created by a command shell can trick trusted binaries into loading attacker-controlled content.
