Anonymous Cloud, Configuration and Subdomain Takeover Scanner

Burp extension that performs a passive scan to identify cloud buckets and then test them for publicly accessible vulnerabilities.

The extension looks at all responses and will note:

  1. AWS S3 bucket URLs.
  2. Azure Storage container URLs.
  3. Google Storage container URLs.


  1. Add the JAR as an extension in Burp.
  2. Add the appropriate targets to scope.
  3. Begin manually browsing and scanning the target.
  4. If you want to test for permissions issues that allow all authenticated AWS/GCP users, then add your personal AWS/GCP credentials, and click the "Set Configuration" button.
  5. If you want to check for potential subdomain takeover vulnerabilities, add API keys for Shodan and Censys (if you want to use both), in addition to a text file list of subdomains (if you want), check the subdomain takeover configuration box, and click the "Set Configuration" button.
