What it detects

This rule detects AWS CloudTrail activity originating from the Pacu and ScoutSuite offensive cloud toolkits identified by their user agent strings. These frameworks were used to enumerate and abuse AWS control-plane access after ~/.aws/credentials theft during the SugarCRM zero-day cloud intrusion, indicating an attacker performing hands-on-keyboard cloud reconnaissance and resource abuse.
