CrowdStrike CCFH-202 CrowdStrike Certified Falcon Hunter Exam Practice Test

A hunting hypothesis is a statement that describes a possible malicious activity that can be tested with data and analysis. A good hunting hypothesis should be specific, testable, and relevant to the problem or goal. In this case, the best hunting hypothesis from the following is that a password guessing attack is being executed against remote access mechanisms such as VPN, as it explains the possible cause and method of the user account lockouts in a specific and testable way. A zero-day vulnerability on a Microsoft Exchange server is too vague and does not explain how it relates to the lockouts. A hacked web application is also too vague and does not specify how it causes the lockouts. Users locking their accounts out because they recently changed their passwords is not a malicious activity and does not account for the increase in calls.

ContextTimeStamp_decimal is the field that shows the system time of the event that triggered the sensor to send data to the cloud. In this case, it would be the time when the file was written. FileTimeStamp_decimal is the field that shows the last modified time of the file, which may not be the same as the time when the file was written. ProcessStartTime_decimal is the field that shows the start time of the process that performed the file write operation, which may not be the same as the time when the file was written. Timestamp is the field that shows the time when the sensor data was received by the cloud, which may not be the same as the time when the file was written.

Bulk Domain Search is the tool that you should use in Falcon to review a list of domains recently banned by your organization’s acceptable use policy and look for the number of hosts that have visited each domain. Bulk Domain Search is an Investigate tool that allows you to search for multiple domains at once and view their network connection events across all hosts in your environment. It shows information such as domain name, number of hosts visited, number of detections generated, etc. for each domain. Create a custom alert for each domain, Allowed Domain Summary Report, and IP Addresses Search are not tools that you should use for this purpose.

The Process Timeline Link is what you click to jump to a Process Timeline from many pages in Falcon, such as a Hash Search. The Process Timeline Link is an icon that looks like three horizontal bars with dots on them. It appears next to each process name or ID on various pages in Falcon, such as Hash Search results, Detection details, Event Search results, etc. Clicking on it will open a new tab with the Process Timeline for that process. The PID, the Process ID or Parent Process ID, and the CID are not what you click to jump to a Process Timeline.

 The Events Data Dictionary found in the Falcon documentation is useful for writing hunting queries because it provides a reference of information about the events found in the Investigate > Event Search page of the Falcon Console. The Events Data Dictionary describes each event type, field name, data type, description, and example value that can be used to query and analyze event data. The Streaming API Event Dictionary, Hunting and Investigation, and Event stream APIs are not documentation that provide details about key data fields and sensor events.

Technique ID is the information that is provided from the MITRE ATT&CK framework in a detection’s Execution Details. Technique ID is a unique identifier for each technique in the MITRE ATT&CK framework, such as T1059 for Command and Scripting Interpreter or T1566 for Phishing. Technique ID helps to map a detection to a specific adversary behavior and tactic. Grouping Tag, Command Line, and Triggering Indicator are notinformation that is provided from the MITRE ATT&CK framework in a detection’s Execution Details.

 The ParentProcessld_decimal event field is what the Process Timeline Events Details table will populate the Parent Process ID and the Parent File columns with when the cloudable Event data contains it. The ParentProcessld_decimal event field is the decimal representation of the process identifier for the parent process of the target process. It can be used to trace the process ancestry and identify potential malicious activity. The ContextProcessld_decimal, RawProcessld_decimal, and RpcProcessld_decimal event fields are not used to populate the Parent Process ID and the Parent File columns.

The Hunting and Investigation guide contains example Event Search queries useful for threat hunting. These queries are based on common threat hunting use cases and scenarios, such as finding suspicious processes, network connections, registry activity, etc. The guide also explains how to customize and modify the queries to suit different needs and environments. The guide does not contain a list of all event types and their syntax, as that information is provided in the Events Data Dictionary. The guide also does not contain example Event Search queries useful for Falcon platform configuration, as that is not the focus of the guide.

The rename command is used to rename fields while using transforming commands such as table, chart, and stats. It can be used after the transforming command and specify the old and new field names with the AS keyword. You can rename fields as it would not affect sub-queries and statistical analysis, as long as you use the correct field names in your queries. The renamed keyword and the desired name after the field name are not valid ways to rename fields.
