What it detects

This rule detects execution of a binary named Mixed Reality.exe from the Windows Media Player directory, a masquerading trick used by Operation DragonReturn to stage its multi-stage DcRAT loader. The China-nexus actor placed the payload under a trusted vendor folder to blend with legitimate software while conducting espionage against Indian tax infrastructure, so early detection exposes the loader before injection and C2.
