Sandcastle – AWS S3 Bucket Enumeration Tool


Sandcastle is a Python-based Amazon AWS S3 Bucket Enumeration Tool, formerly known as bucketCrawler. The script takes a target’s name as the stem argument (e.g. shopify) and iterates through a file of bucket name permutations.

Sandcastle - AWS S3 Bucket Enumeration Tool


Amazon S3 [Simple Storage Service] is cloud storage for the Internet. To upload your data (photos, videos, documents etc.), you first create a bucket in one of the AWS Regions. You can then upload any number of objects to the bucket.

In terms of implementation, buckets and objects are resources, and Amazon S3 provides APIs for you to manage them.

Examples of the kinds of bucket names it would look for:

  • -training
  • -bucket
  • -dev
  • -attachments
  • -photos
  • -elasticsearch
  • […]

You can find the example bucket names file here.
