This is the difference between a Host Search and a Host Timeline. A Host Search is an Investigate tool that allows you to view events by category, such as process executions, network connections, file writes, etc. A Host Timeline is an Investigate tool that allows you to view all events in chronological order, without any categorization. Both tools can be used for detection investigation and proactive hunting, depending on the use case and preference. You can access a Host Search from a detection or manually enter the host details. You can also populate the Host Timeline fields manually or from other pages in Falcon.

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.

Stacking (Frequency Analysis) is a recommended technique to find unique outliers among a set of data in the Falcon Event Search. As explained above, 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. Hunt-and-Peck Search Methodology, Time-based Searching, and Machine Learning are not specific techniques to find unique outliers among a set of data.

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.

The Linux Sensor report is where an analyst would find information about shells spawned by root, Kernel Module loads, and wget/curl usage. The Linux Sensor report is a pre-defined report that provides a summary view of selected activities on Linux hosts. It shows information such as process execution events, network connection events, file write events, etc. that occurred on Linux hosts within a specified time range. The Sensor Health report, the Sensor Policy Daily report, and the Mac Sensor report do not provide the same information.
