S3Scanner: Scan for open S3 buckets and dump
A tool to find open S3 buckets and dump their contents
The tool takes in a list of bucket names to check. Found S3 buckets are output to file. The tool will also dump or list the contents of ‘open’ buckets locally.
This tool will attempt to get all available information about a bucket, but it’s up to you to interpret the results.
Settings available for buckets:
- Object Access (object in this case refers to files stored in the bucket)
- List Objects
- Write Objects
- ACL Access
- Read Permissions
- Write Permissions
Any or all of these permissions can be set for the 2 main user groups:
- Authenticated Users
- Public Users (those without AWS credentials set)
- (They can also be applied to specific users, but that’s out of scope)
What this means: Just because a bucket returns “AccessDenied” for it’s ACLs doesn’t mean you can’t read/write to it. Conversely, you may be able to list ACLs but not read/write to the bucket
(Optional) virtualenv venv && source ./venv/bin/activate
pip install -r requirements.txt
The tool takes in a list of bucket names to check. Found S3 domains are output to file with their corresponding region in the format ‘domain:region’. The tool will also dump the contents of ‘open’ buckets locally.
