Free CrowdStrike Certified Falcon Hunter CCFH-202b Exam Questions

This is the correct answer for the same reason as above. The Mac Sensor report provides a comprehensive view of activities occurring on Mac hosts, including items of interest that may be hunting or investigation leads. It does not display a listing of all Mac hosts with or without a Falcon sensor installed, nor does it provide a detection focused view of known malicious activities occurring on Mac hosts.

This is the proper method to quantify search results, enabling a hunter to quickly sort and identify outliers. The stats command is used to calculate summary statistics on the results of a search or subsearch, such as count, sum, average, etc. The count by option is used to count the number of events for each distinct value of a field or fields and display them in a table. This can help find rare or common values that could indicate anomalies or deviations from normal behavior.

Stacking (Frequency Analysis) is the best hunting method to use to find events that are outliers inside a network. Stacking involves grouping events by a common attribute and counting their frequency, then sorting them by ascending or descending order to identify rare or common events. This can help find anomalies or deviations from normal behavior that could indicate malicious activity. Time-based searching, machine learning, and searching are not specific hunting methods to find outliers.

A threat hunting framework is a methodology that guides threat hunters in planning, executing, and improving their threat hunting activities. A benefit of using a threat hunting framework is that it provides actionable, repeatable steps to conduct threat hunting in a consistent and efficient manner. A threat hunting framework does not automatically generate incident reports, eliminate false positives, or provide high fidelity threat actor attribution, as these are dependent on other factors such as data sources, tools, and analysis skills.

Scheduled Searches are a way to create event searches that run automatically and recur on a schedule that you set. You can use Scheduled Searches to monitor your environment for specific conditions or patterns, generate reports or alerts, or enrich your data with additional fields or tags. Workflows, Event Search, and Scheduled Reports are not ways to create event searches that run automatically and recur on a schedule.

The ContextProcessld_readable field in a DNS Request event points to the responsible process. The ContextProcessld_readable field is the readable representation of the process identifier for the process that initiated the DNS request. It can be used to identify which process was communicating with a specific domain or IP address. The TargetProcessld_decimal, ContextProcessld_decimal, and ParentProcessId_decimal fields do not point to the responsible process.

This query will return the parent processes responsible for launching badprogram.exe by using a subsearch to find the processrollup2 events where FileName is badprogram.exe, then renaming the TargetProcessld_decimal field to ParentProcessld_decimal and using it as a filter for the main search, then using stats to count the occurrences of each FileName by _time. The other queries will either not return the parent processes or use incorrect field names or syntax.

The Hash Search is an Investigate tool that allows you to search for a file hash and view its process execution history across all hosts in your environment. It shows information such as process name, command line, parent process name, parent command line, etc. for each execution of the file hash. Wildcard searches are permitted with the Hash Search, as long as they are at least four characters long. The Hash Search is available on Linux, as well as Windows and Mac OS X. Module Load History is presented in a Hash Search, along with other information such as File Write History and Detection History.

Discovering internet-facing servers is an example of actor actions during the RECONNAISSANCE phase of the Cyber Kill Chain. The RECONNAISSANCE phase is where the adversary researches and identifies targets, vulnerabilities, and attack vectors. Discovering internet-facing servers is a way for the adversary to find potential entry points or weaknesses in the target network.

MITRE ATT&CK Navigator is a tool that allows a threat hunter to populate and colorize all known adversary techniques in a single view. It is based on the MITRE ATT&CK framework, which is a knowledge base of adversary behaviors and tactics. The tool enables threat hunters to create custom matrices, layers, annotations, and filters to explore and model specific adversary techniques, with links to intelligence and case studies.
