Why each option

bucket_finder.rb with the --download flag retrieves and saves a list of publicly accessible S3 buckets discovered through wordlist-based enumeration.

ANames of S3 buckets found in the wordlist

The bucket names in the wordlist are the input used for enumeration testing, not the download output; the tool tests names from the list rather than downloading the wordlist itself.

BPermission settings for identified S3 buckets

bucket_finder.rb does not retrieve IAM permission configurations or ACL settings for identified buckets; it focuses on determining public accessibility rather than auditing permission structures.

CContent from publicly accessible S3 buckets

The actual objects and files stored inside S3 buckets are not what the --download flag retrieves; the tool identifies and records which buckets are accessible rather than pulling the contents stored within them.

DList of publicly accessible S3 bucketsCorrect

bucket_finder.rb uses a wordlist to generate and test potential S3 bucket names against AWS, identifying which are publicly accessible. The --download flag causes the tool to download and persist the list of publicly accessible S3 buckets found during the scan, saving the enumeration results locally for further analysis rather than only printing them to stdout.
