Additional Details (leave it blank if not applicable)

Many organizations inadvertently leak their AWS configurations to the Internet. This causes a significant impact through leaked key material and allows attackers to use those keys to authenticate to AWS as that account.

These templates search for the /.aws/credentials and /.aws/config files which are used by the AWS CLI to programmatically interface with AWS.

This PR contains two templates since they are similar.
