What it detects

This rule detects the AWS SSO ListAccountRoles call, the reconnaissance step Red Canary noted adversaries performing after obtaining a cached SSO access token to enumerate assignable roles. A burst of ListAccountRoles from an unfamiliar source can indicate an actor mapping available roles before assuming credentials.
