security - Find the owner of an AWS Access Key

Question

I have a service which uses an AWS Access Key to push stuff to S3. I am going to sunset the service and I have the AWS Access Key and Secret. However, I can't find this key in the IAM or security credentials for the account.

Is there a way to enumerate all the access keys for an entire AWS account?

If you don't have access to your account's primary access key, but you do have an access key with sufficient access to IAM, you can enumerate all the users in the account and then list the access keys for each of them. For example:

for user in $(aws iam list-users --output text | awk '{print $NF}'); do
    aws iam list-access-keys --user $user --output text
done
