Summary
This detection rule focuses on monitoring changes to the Windows registry, specifically the `PythonFunctionWarnings` setting within Microsoft Excel. The rule is designed to flag any modifications that disable security warnings related to the execution of Python functions in Excel. By altering this registry value, threat actors could execute potentially harmful Python code undetected, as the corresponding alerts would be suppressed. The rule aims to protect environments utilizing Excel's new capability to run Python scripts, which is beneficial for data analysis but can be exploited if security measures are overlooked. Monitoring this registry modification is critical for identifying possible attempts to bypass security protocols. The level of detection is set to high due to the potential ramifications of allowing unmonitored Python execution within Excel.
