What it detects

This rule detects PowerShell executing a script named googleearth.ps1, the masqueraded PowerShower component Cloud Atlas deploys to run reconnaissance and staging logic. The benign looking script name conceals malicious PowerShell activity. Detecting this invocation surfaces execution of the group tooling on the host.
