You are notified by a third-party that a program may have redirected traffic to a malicious domain. Which Falcon page will assist you in searching for any domain request information related to this notice?
Correct Answer:
B
According to the [CrowdStrike website], the Investigate page is where you can search for and analyze various types of data collected by the Falcon platform, such as events, hosts, processes, hashes, domains, IPs, etc1. You can use various tools, such as Event Search, Host Search, Process Timeline, Hash Search, Bulk Domain Search, etc., to perform different types of searches and view the results in different ways1. If you want to search for any domain request information related to a notice from a third-party, you can use the Investigate page to do so1. For example, you can use the Bulk Domain Search tool to search for the malicious domain and see which hosts and processes communicated with it1. You can also use the Event Search tool to search for DNSRequest events that contain the malicious domain and see more details about the query and response1.
What happens when a quarantined file is released?
Correct Answer:
D
According to the CrowdStrike Falcon® Data Replicator (FDR) Add-on for Splunk Guide, when you release a file from quarantine, you are restoring it to its original location and allowing it to execute on any host in your organization1. This action also removes the file from the quarantine list and deletes it from the CrowdStrike Cloud1.
Within the MITRE-Based Falcon Detections Framework, what is the correct way to interpret Keep Access > Persistence > Create Account?
Correct Answer:
A
According to the [CrowdStrike website], the MITRE-Based Falcon Detections Framework is a way of categorizing and describing detections based on the MITRE ATT&CK knowledge base ofadversary behaviors and techniques. The framework uses three levels of granularity: category, tactic, and technique. The category is the highest level and represents the main objective of an adversary, such as initial access, execution, credential access, etc. The tactic is the second level and represents the sub-objective of an adversary within a category, such as persistence, privilege escalation, defense evasion, etc. The technique is the lowest level and represents the specific way an adversary can achieve a tactic, such as create account, modify registry, obfuscated files or information, etc. Therefore, the correct way to interpret Keep Access > Persistence > Create Account is that an adversary is trying to keep access through persistence by creating an account.
The primary purpose for running a Hash Search is to:
Correct Answer:
D
According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the Hash Search tool allows you to search for one or more SHA256 hashes and view a summary of information from Falcon events that contain those hashes1. The summary includes the hostname, sensor ID, OS, country, city, ISP, ASN, geolocation, process name, command line, and organizational unit of the host that loaded or executed those hashes1. You can also see a count of detections and incidents related to those hashes1. The primary purpose for running a Hash Search is to review information surrounding a hash??s related activity, such as which hosts and processes were involved, where they were located, and whether they triggered any alerts1.
After pivoting to an event search from a detection, you locate the ProcessRollup2 event. Which two field values are you required to obtain to perform a Process Timeline search so you can determine what the process was doing?
Correct Answer:
D
According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the Process Timeline search requires two parameters: aid (agent ID) and TargetProcessId_decimal (the decimal value of the process ID). These fields can be obtained from the ProcessRollup2 event, which contains information about processes that have executed on a host1.
