User Search is a search page that allows a threat hunter to search for user activity across endpoints and correlate it with other events. This can help differentiate testing, DevOPs, or general user activity from adversary behavior by identifying anomalous or suspicious user actions, such as logging into multiple systems, running unusual commands, or accessing sensitive files.

A Falcon threat hunting lead is a piece of information that can be used to initiate or guide a threat hunting activity within the Falcon platform. A routine threat hunt query showing process executions of single letter filename (e.g., a.exe) from temporary directories is an example of a Falcon threat hunting lead, as it can indicate potential malicious activity that can be further investigated using Falcon data and features. Security appliance logs, help desk tickets, and external reports are not examples of Falcon threat hunting leads, as they are not directly related to the Falcon platform or data.

When exporting the results of an event search, the data that is saved in the exported file depends on the mode and the tab that is selected. In this case, the mode is Verbose and the tab is Statistics, as indicated by the stats command. Therefore, the data that is saved in the exported file is the results of the Statistics tab, which shows the count of events by ComputerName. The text of the query, all events in the Events tab, and no data are not correct answers.

When performing a raw event search via the Events search page, Event Actions are pivotable workflows that allow you to perform various tasks related to the event or the host. For example, you can connect to a host using Real Time Response, run pre-made event searches based on the event type or name, or pivot to other investigatory pages such as host search, hash search, etc. Event Actions do not contain audit information log, summary of actions taken by the Falcon sensor, or the event name defined in the Events Data Dictionary.

This process tree indicates a phishing attack, as it shows a user opening an email attachment (outlook.exe) that launches a malicious macro (cmd.exe) that downloads and executes a payload (powershell.exe) that connects to a remote server (svchost.exe). A phishing attack is a type of social engineering attack that uses deceptive emails or messages to trick users into opening malicious attachments or links that can compromise their systems or credentials.
