What it detects

This rule detects the AWS SSO CreateToken and GetRoleCredentials calls against sso.amazonaws.com, the API sequence Red Canary described adversaries using to replay cached SSO tokens stolen from the .aws sso cache. When these calls originate from multiple IP addresses in a short window they indicate an actor exchanging a stolen access token for STS role credentials.
