Detection: IAM Group Administrator Policy Attached

Overview

Detect when the AdministratorAccess policy was attached to an IAM group. Assigning this policy grants all group members full access to AWS resources, increasing the risk of unauthorized privilege escalation, security misconfigurations, or potential misuse. Monitoring these actions ensures that administrative permissions are only assigned when necessary and adheres to the principle of least privilege.

This detection uses a named query:

select
  tp_timestamp as timestamp,
string_split(event_source, '.')[1] || ':' || event_name as operation,
request_parameters ->> 'groupName' as resource,
user_identity.arn as actor,
tp_source_ip as source_ip,
tp_index as account_id,
aws_region as region,
tp_id as source_id,
*

from
  aws_cloudtrail_log
where
  event_source = 'iam.amazonaws.com'
  and event_name = 'AttachGroupPolicy'
  and (request_parameters ->> 'policyArn') like 'arn:%:iam::aws:policy/AdministratorAccess'
  and error_code is null

order by
  event_time desc;
