# AWS EC2 key pair creation attempt with known suspicious naming convention

## Goal{% #goal %}

Detect when a key pair is created using a long-term access key that has a suspicious naming convention.

## Strategy{% #strategy %}

This rule lets you monitor CloudTrail logs for `CreateKeyPair` events created from a long-term access key and shows the identity that initiated the event.

Datadog's security research team has observed key pair naming conventions that include a common noun followed by a string of alphanumeric characters. The attack pattern can indicate that the long term access key used has been compromised, `{{@userIdentity.accessKeyId}}`.

## Triage and response{% #triage-and-response %}

1. Determine if the user, `{{@userIdentity.arn}}`, should be generating a new key pair.
1. Investigate the the user behavior and access information:
   - Review the user agent, IP address, and other identifying information for evidence of an abnormal access.
   - Look at additional events, such as `{{@@userIdentity.arn}}` and `{{@userIdentity.accessKeyId}}` attaching a key pair to an EC2 instance during the surrounding timeframe. The related events can be searched in EC2 logs: `@eventSource:ec2.amazonaws.com` and `@evt.name:ImportKeypair`.
1. If the behavior is abnormal for the user and your environment:
   - Rotate the credentials.
   - Investigate if the same credentials took other unauthorized actions.
   - Begin your company's IR process and investigate.
