+  name: ElasticBeanTalk Subdomain Takeover Detection

+  severity: high
+  description: ElasticBeanTalk subdomain takeover detected. A subdomain takeover occurs when an attacker gains control over a subdomain of a target domain. Typically, this happens when the subdomain has a canonical
+    name (CNAME) in the Domain Name System (DNS), but no host is providing content for it.

+      Only CNAMEs with region specification are hijackable.
+      You need to claim the CNAME in AWS portal (https://aws.amazon.com/) or via AWS CLI to confirm the takeover.
+      Do not report this without claiming the CNAME.
+      CLI command to verify the availability of the environment:
+      aws elasticbeanstalk check-dns-availability --region {AWS_REGION} --cname-prefix {CNAME_PREFIX}
+      For example:
+      CNAME - 2rs3c.eu-west-1.elasticbeanstalk.com
+      Command - aws elasticbeanstalk check-dns-availability --region eu-west-1 --cname-prefix 2rs3c
