### Description

An internal identity performed an operation on multiple regions, considerably more than usual. This may indicate an attacker's attempt to identify all available resources in the cloud environment.

### Attacker's Goals

* Discover cloud resources that are available within the environment and leverage them to perform additional attacks against the organization.
* Detect unused geographic regions and leverage them to evade detection of malicious operations.

### Investigative actions

* Check the identity designation.
* Verify that the identity did not perform any operation in a region that it shouldn't.

## 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/analytics-alerts/alerts-by-name/multi-region-enumeration-activity.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.
