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 file name, path, Local and Global prevalence are indicators that can provide an initial analysis of the file without relying on external sources or tools. The file name can indicate the purpose or origin of the file, such as if it is a legitimate application or a malicious payload. The file path can indicate where the file was located or executed from, such as if it was in a temporary or system directory. The Local and Global prevalence can indicate how common or rare the file is within the environment or across all Falcon customers, which can help assess the risk or impact of the file.

Weaponization is the stage of the Cyber Kill Chain where the actor does not interact with the victim endpoint(s). Weaponization is where the actor prepares or packages the exploit or payload that will be used to compromise the target. This stage does not involve any communication or interaction with the victim endpoint(s), as it is done by the actor before delivering the weaponized content. Exploitation, Command & Control, and Installation are all stages where the actor interacts with the victim endpoint(s), either by executing code, establishing communication, or installing malware.

Non-network processes are processes that are not expected to communicate over the network, such as notepad.exe. If they make an outbound network connection, it could indicate that they are compromised or maliciously used by an adversary. PowerShell running an execution policy of RemoteSigned is a default setting that allows local scripts to run without digital signatures. An Internet browser performing multiple DNS requests is a normal behavior for web browsing. PowerShell launching a PowerShell script is also a common behavior for legitimate tasks.

The Falcon Detections page will attempt to decode Encoded PowerShell Command line parameters when the -Command parameter is present. The -Command parameter allows PowerShell to execute a specified script block or string. If the script block or string is encoded using Base64 or other methods, the Falcon Detections page will try to decode it and show the original command. The -Hidden, -e, and -nop parameters are not related to encoding or decoding PowerShell commands.
