What it detects

This rule detects an SNS Subscribe call using the email protocol, an exfiltration setup step in the AWS SNS abuse scenario researched by Elastic. Attackers subscribe an external email address to a topic then publish stolen credentials or data to it over a trusted AWS channel. Email subscriptions created by unexpected principals should be reviewed for data theft.
