Exploring AWS STS AssumeRoot
Elastic explores the AWS Security Token Service (STS) AssumeRoot application programming interface (API) operation, which grants temporary root-level credentials for member accounts in an AWS organization. The article demonstrates a practical attack chain where an adversary with compromised IAM credentials uses AssumeRoot to obtain temporary root access, then creates a persistent login profile for console access. Detection and hardening guidance includes CloudTrail-based hunting queries, restrictions on task policies, and enforcement of multifactor authentication (MFA) for sensitive operations.
Why it matters: AWS customers managing multi-account organizations need to detect and restrict AssumeRoot usage immediately, as compromised IAM credentials can lead to root account compromise; security teams should enable organization-wide CloudTrail logging and deploy anomaly detection rules to identify unusual AssumeRoot calls by IAM users or on new member accounts.
