Hunting GCP Buckets

GCP Buckets are almost 100% identical to AWS S3 Buckets.

Theory: This call is based on OpenStack; maybe most cloud environments will be the same.

Using @digininja's CloudStorageFinder diff the following files:

diff bucket_finder.rb google_finder.rb

The main differences are the URLs:

  • AWS Supports HTTP and HTTPS
  • AWS S3 URLs: http://s3-region.amazonaws.com, i.e.: http://s3-eu-west-1.amazonaws.com.
  • GCP Endpoint: https://storage.googleapis.com

How to find buckets using CloudStorageFinder:

Create a wordlist with any name; in our example, it is wordlist.txt.

$ ruby google_finder.rb wordlist.txt
