What it detects

This rule detects a curl download of a remote resource piped directly into a cmd.exe interpreter which is the ClickFix delivery step of the SCMBanker Mexican banking-fraud toolkit. Adversaries trick victims into pasting a clipboard command that fetches and runs a staged validation script. Catching this pipe-to-interpreter pattern exposes the initial foothold before the wider toolkit is pulled.
