What it detects

This rule detects abuse of the Selenium Grid binary-location parameter to point at a Python interpreter with an inline command flag which threat actors use to gain instant remote code execution on exposed Selenium nodes and deploy crypto-miners. The combination of the browser binary flag with a scripting interpreter is a reliable exploitation signature for this misconfiguration.
