# Indicator investigation

Cortex XSOAR enables you to centralize and manage every aspect of your TIM investigation. Create, extract, and enrich indicators and explore their relationships to gain deeper insights.

After you start ingesting indicators into Cortex XSOAR, you can start your investigation, including creating indicators, adding indicators to an incident, extracting indicators, exporting indicators, etc.

When investigating an indicator, you can see the following tabs:

* **Summary**

  View verdict, enrich, expire, delete and exclude the indicator, add relationships, view related incidents, and add comments. Add or remove tags, which can help classify known threats. For example, you may want to group specific malware indicators that are part of ransomware, such as trojan or loader.
* **Additional Details**

  Add or view any community notes for sharing and any custom details.

When investigating an indicator, you can perform actions on the indicator, such as:

| Action                         | Description                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             |
| ------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Enrich an indicator            | You can view detailed information about the indicator (WHOIS information for example), using third-party integrations such as VirusTotal and IPinfo. For more information, see [Extract and enrich an indicator](/cortex-xsoar-8-on-prem/8.13/investigate-and-respond-to-threats/threat-intel-management/indicator-investigation/extract-and-enrich-an-indicator.md).                                                                                                                                                                   |
| Expire an indicator            | You may want to expire an indicator to filter out less relevant alerts, allowing analysts to focus on active threats. For more information, see [Expire an indicator](/cortex-xsoar-8-on-prem/8.13/investigate-and-respond-to-threats/threat-intel-management/indicator-investigation/expire-an-indicator.md).                                                                                                                                                                                                                          |
| Manage indicator relationships | Indicator relationships are connections between different indicators. These relationships can be IP addresses related to one another, domains impersonating legitimate domains, etc. Relationships are created from threat intel feeds and enrichment integrations that support the automatic creation of relationships. For more information, see [Manage indicator relationships](/cortex-xsoar-8-on-prem/8.13/investigate-and-respond-to-threats/threat-intel-management/indicator-investigation/manage-indicator-relationships.md). |
| Delete and exclude indicators  | Indicators added to an exclusion list are disregarded by the system and are not created or involved in automated flows. For more information, see [Delete and exclude indicators](/cortex-xsoar-8-on-prem/8.13/investigate-and-respond-to-threats/threat-intel-management/indicator-investigation/delete-and-exclude-indicators.md).                                                                                                                                                                                                    |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xsoar-8-on-prem/8.13/investigate-and-respond-to-threats/threat-intel-management/indicator-investigation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
