Hace algunas semanas me llegó este mensaje por parte de AWS

We are writing to notify you that you have configured your S3 bucket(s) to be publicly accessible, and this may be a larger audience than you intended. By default, S3 buckets allow only the account owner to access the contents of a bucket; however, customers can configure S3 buckets to permit public access. Public buckets are accessible by anyone on the Internet, and content in them may be indexed by search engines. We recommend enabling the S3 Block Public Access feature on buckets if public access is not required. S3 bucket permissions should never allow “Principal”:”*” unless you intend to grant public access to your data. Additionally, S3 bucket ACLs should be appropriately scoped to prevent unintended access to “Authenticated Users” (anyone with an AWS account) or “Everyone” (anyone with Internet access) unless your use case requires it. For AWS’s definition of “Public Access,” please see The Meaning of “Public” [1].
