### Description

EC2 infrastructure enumeration activity detected within a specific AWS region.

### Attacker's Goals

* Discover EC2 resources and network setup to find potential weaknesses or targets.
* Use the gathered information to enable lateral movement, privilege escalation, or data exfiltration.

### Investigative actions

* Identify and review the specific EC2 enumeration API calls executed and their frequency.
* Verify the identity performing the calls and assess if this behavior is typical or anomalous.
* Correlate with other discovery activities and check related logs for suspicious patterns or subsequent actions.

## 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/aws-ec2-infrastructure-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.
