Description
Detects when an AWS member account is registered as a delegated administrator for an AWS service via the RegisterDelegatedAdministrator API. Delegated administrators receive service-level administrative access across the entire organization without being the management account. An attacker who compromises a principal with organizations permissions can abuse overly permissive managed policies to register a member account they control as a delegated administrator, then use that privileged access to escalate privileges organization-wide and compromise all member accounts.
