AWS STS GetFederationToken with AdministratorAccess in Request

Identifies successful calls to AWS STS GetFederationToken where request parameters reference AdministratorAccess. This API returns temporary security credentials for a federated user with permissions bounded by the calling IAM user and any inline session policy passed in the request. Supplying or referencing the AWS managed AdministratorAccess policy (or an equivalent string in the policy payload) can grant broadly privileged temporary credentials and may indicate privilege abuse or dangerous automation.

event.dataset: "aws.cloudtrail"
    and event.provider: "sts.amazonaws.com"
    and event.action: "GetFederationToken"
    and event.outcome: "success"
    and aws.cloudtrail.request_parameters: *AdministratorAccess*

False Positives

⚠ Highly unusual for legitimate workflows to embed or reference full administrator access in GetFederationToken session policies; if found, it is often legacy or misconfigured tooling. Confirm with the owning team and replace with least-privilege session policies. Tune only after documented approval.
