What it detects

This rule detects a DLL being loaded from the %localappdata%\Temp\wps\INetCache path, where the WPS Office exploit chain plants an attacker DLL named by MD5 hash for side-loading. Legitimate DLLs are not resolved from this cache directory. This indicates DLL search-order hijacking used by the APT-C-60 downloader.
