Explanation
According to the CrowdStrike Falcon Data Replicator (FDR) Add-on for Splunk Guide, the Always Block action allows you to block a file from executing on any host in your organization based on its hash value2. This action can be used to prevent known malicious files from running on your endpoints2.

Explanation
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.

Explanation
According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the Bulk Domain Search tool allows you to search for one or more domains and view a summary of information from Falcon events that contain those domains1. The summary includes the domain name, IP address, country, city, ISP, ASN, geolocation, hostname, sensor ID, OS, process name, command line, and organizational unit of the host that communicated with those domains1. This means that the tool contains domain information along with IP lookup information1.

Explanation
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.

Explanation
According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, Event Actions are automated searches that can be used to pivot between related events and searches1. They are available in various tools, such as Event Search, Process Timeline, Host Timeline, etc1. You can select one or more events and perform various actions, such as show a process timeline, show a host timeline, show associated event data, show a +/- 10-minute window of events, etc1. These actions can help you investigate and analyze events more efficiently and effectively1.
