You can use BBOT to enumerate storage buckets. Supported providers are: AWS, Google, Azure, DigitalOcean, and Firebase.

Buckets are discovered from web content and enumerated based on derivatives of discovered DNS names. For example, if your target is tesla.com and BBOT discovers a subdomain www.tesla.com, it will visit the website and extract bucket names from its HTML content. Additionally, it will try each of the following bucket names:

• www.tesla.com
• www.tesla
• www-tesla-com
• www-tesla
• wwwteslacom
• wwwtesla

For each bucket found, BBOT will check whether it's open (world-readable) and also whether it's vulnerable to subdomain takeover. Note that buckets discovered with the bucket_* modules are not guaranteed to be owned by the target.

# enumerate buckets for evilcorp.com
bbot -t evilcorp.com -f subdomain-enum cloud-enum

# single cloud provider + permutations (-dev, -test, etc.)
bbot -t evilcorp.com -m bucket_aws -c modules.bucket_aws.permutations=true
