What it detects

This rule detects the WannaCry payload tasksche.exe being launched by its dropper service process mssecsvc.exe. This parent-child relationship reflects the core WannaCry infection chain where the network worm component deploys the encryptor. Observing this process lineage indicates an active WannaCry compromise.
