What it detects

This rule detects the legitimate signed Analyzer.exe loading a non-standard mglobal.dll from outside the Windows system directories, a DLL side-loading technique observed by 360 Advanced Threat Research in an APT32 intrusion where the sideloaded module decrypts and executes the next stage directly in memory. Adversaries pair a trusted executable with an attacker-supplied DLL of the same base name to run code under a benign process and evade application controls.
