Turn on the Script-Based Execution Monitoring prevention policy setting to enable the "Falcon sensor to monitor the contents of scripts and shells that are popular mechanisms for executing malicious code on hosts. This setting does not kill or block scripts."

Scripting languages:

Excel 4.0 macros

JScript

VBA Macros

VBScript

The Sensor Visibility setting that should be turned on within the Prevention policy settings to monitor suspicious VBA macros is Script-based Execution Monitoring. Script-based Execution Monitoring is a feature that enables the Falcon sensor to monitor and prevent malicious script execution on Windows systems. The feature uses machine learning and behavioral analysis to detect suspicious scripts or commands executed by various script interpreters, such as PowerShell, WScript, CScript, or Bash. VBA (Visual Basic for Applications) is a scripting language that can be embedded in Microsoft Office documents, such as Word or Excel. VBA macros can be used to automate tasks or perform actions within the documents, but they can also be abused by attackers to deliver malware or execute malicious code. Script-based Execution Monitoring can help detect and prevent such attacks by monitoring the contents of VBA macros for execution of malicious content.

The statement that describes what is recommended for the Default Sensor Update policy is that the Default Sensor Update policy should align to an organization’s overall sensor updating practice while leveraging Auto N-1 and Auto N-2 configurations where possible. As explained in question 139, the Default Sensor Update policy is a “catch-all” policy that applies to any host that is not assigned to a specific Sensor Update policy. Therefore, it is recommended that the Default Sensor Update policy should align to your organization’s overall sensor updating practice, such as how frequently and how quickly you want to update your sensors. It is also recommended that you leverage the Auto N-1 and Auto N-2 configurations, which allow you to automatically update your sensors to the latest or second-latest sensor version without requiring manual intervention1.

A workflow condition consists of a parameter, an operator, and a value. A workflow condition is a rule that defines when a workflow should be triggered based on certain criteria or filters. A parameter is a variable or attribute that can be used to filter or match detection events, such as severity, tactic, or host group. An operator is a symbol or word that specifies how to compare or evaluate the parameter and the value, such as equals, contains, or greater than. A value is a constant or expression that provides the expected or desired result for the parameter, such as high, credential dumping, or default group1.

The exclusion pattern that will prevent detections on a file at C:\Program Files\My Program\My Files\program.exe is \Program Files\My Program\My Files*. This pattern will match any file under the My Files folder, including program.exe, and exclude them from detections. The other patterns are either incorrect or too broad to prevent detections on this specific file. Reference: [CrowdStrike Falcon User Guide], page 37.
