What it detects

This rule detects a CurrentVersion Run or RunOnce registry value whose data references a .ps1 PowerShell script, the persistence used in the GST-phishing campaign to relaunch the Remcos RAT loader at logon. A Run key pointing at a script rather than a signed executable is an atypical auto-start that lets the multi-stage .NET chain re-establish itself, so catching the registry write exposes persistence early.
