A leading wildcard is a wildcard that is placed at the beginning of a search term, such as * or ?. A leading wildcard matches any characters that precede the specified term. For example, filemod:/system32/ntdll.dll matches any file modification events that end with /system32/ntdll.dll, regardless of the drive letter or the directory name. A leading wildcard is not recommended unless absolutely necessary because it carries a significant performance penalty for the search. This is because the search engine has to scan the entire index for possible matches, rather than using the index to quickly narrow down the results1.

The other options are not examples of leading wildcards. A. filemod:system32/ntdll.dll is an exact match query that matches only file modification events that are exactly system32/ntdll.dll. B. filemod:system32/ntdll.dll is a trailing wildcard query that matches any file modification events that start with system32/ and end with ntdll.dll, regardless of the characters in between. D. filemod:system32/ntdll.dll is a trailing wildcard query that matches any file modification events that start with system32/ntdll.dll, regardless of the characters that follow. References:

The reputation that was used by the sensor for the decision to terminate the process was the effective reputation. The effective reputation is the reputation that the sensor uses to evaluate and enforce policy rules on the endpoint. The effective reputation is determined by the following factors:

• The initial cloud reputation, which is the reputation that the Carbon Black Cloud assigns to the file based on its analysis and threat intelligence feeds.
• The actioned reputation, which is the reputation that the administrator assigns to the file through the Carbon Black Cloud console, such as approve, ban, or dismiss.
• The current cloud reputation, which is the reputation that the Carbon Black Cloud updates for the file based on new information or changes in the threat landscape.

The effective reputation is the highest priority reputation among these three factors. For example, if the initial cloud reputation is SUSPECT_MALWARE, the actioned reputation is APPROVED, and the current cloud reputation is KNOWN_MALWARE, the effective reputation will be APPROVED, because it has the highest priority. The sensor will use the effective reputation to apply the policy rules on the endpoint. In this case, the process will not be blocked by the rule [Suspected malware] [Invokes a command interpreter] [Terminate process], because the effective reputation is not SUSPECT_MALWARE.

In the question scenario, the effective reputation for the process was SUSPECT_MALWARE, which means that either the initial cloud reputation, the actioned reputation, or the current cloud reputation was SUSPECT_MALWARE, and there was no higher priority reputation that overrode it. Therefore, the sensor used the effective reputation to enforce the policy rule and terminate the process. References:

 The Investigate page in the VMware Carbon Black Cloud Endpoint Standard console is where the security administrator can perform a search to further inspect the script-based attack that was coded into Excel VBA. The Investigate page allows the administrator to use advanced search techniques to query the endpoint data collected by the VMware Carbon Black Cloud sensors. The administrator can use various fields and operators to filter and refine the search results, such as process_name, file_name, file_path, file_type, file_description, and more. The administrator can also use the processtree view to visualize the process execution and the event details to examine the process activity. For example, the administrator can use the following search query to find all the processes that have a file type of Excel VBA:

file_type:EXCEL_VBA

This query will return all the processes that have a file type of EXCEL_VBA, which is a file type that indicates the file contains Excel VBA code. The file_type field is a string that indicates the type of the file based on its content and format. The possible values for this field are:

• EXE: Executable file
• DLL: Dynamic-link library file
• SYS: System file
• BAT: Batch file
• CMD: Command file
• VBS: Visual Basic Script file
• JS: JavaScript file
• PS1: PowerShell Script file
• HTA: HTML Application file
• MSI: Windows Installer file
• DOC: Microsoft Word document file
• XLS: Microsoft Excel spreadsheet file
• PPT: Microsoft PowerPoint presentation file
• PDF: Portable Document Format file
• SWF: Shockwave Flash file
• JAR: Java Archive file
• CLASS: Java class file
• PY: Python script file
• SH: Shell script file
• PL: Perl script file
• RB: Ruby script file
• PHP: PHP script file
• ASP: Active Server Pages file
• ASPX: Active Server Pages Extended file
• HTML: HyperText Markup Language file
• XML: Extensible Markup Language file
• DOCM: Microsoft Word document with macros file
• XLAM: Microsoft Excel add-in with macros file
• XLSM: Microsoft Excel spreadsheet with macros file
• XLTM: Microsoft Excel template with macros file
• PPTM: Microsoft PowerPoint presentation with macros file
• POTM: Microsoft PowerPoint template with macros file
• PPAM: Microsoft PowerPoint add-in with macros file
• EXCEL_VBA: Excel Visual Basic for Applications file
• WORD_VBA: Word Visual Basic for Applications file
• POWERPOINT_VBA: PowerPoint Visual Basic for Applications file
• OUTLOOK_VBA: Outlook Visual Basic for Applications file
• ACCESS_VBA: Access Visual Basic for Applications file
• PROJECT_VBA: Project Visual Basic for Applications file
• VISIO_VBA: Visio Visual Basic for Applications file
• PUBLISHER_VBA: Publisher Visual Basic for Applications file
• INFOPATH_VBA: InfoPath Visual Basic for Applications file
• ONENOTE_VBA: OneNote Visual Basic for Applications file
• UNKNOWN: Unknown file type

Therefore, by using the Investigate page in the VMware Carbon Black Cloud Endpoint Standard console, the security administrator can perform a search to further inspect the script-based attack that was coded into Excel VBA. References:
