What it detects

This rule detects creation of a scheduled task named RunFullMemoryDiagnostic or ProcessMemoryDiagnosticEvents whose action launches a script host, mimicking legitimate Windows memory diagnostic tasks. LitterDrifter abuses these trusted task names to blend its persistence into normal Windows components. The mismatch between the trusted name and a script host action reveals the worm persistence.
