Data storage and S3 buckets

When conducting a penetration test on AWS, profiling data storage and S3 buckets is crucial for identifying potential vulnerabilities and security misconfigurations. With its AWS module support, PowerShell provides a flexible and powerful environment for performing such assessments. Next, we’ll look at a detailed explanation with examples of how PowerShell can be used to profile data storage and S3 buckets as part of a penetration test.

Listing all S3 buckets

PowerShell can be used to enumerate all S3 buckets in an AWS account:

# List all S3 buckets
Get-S3Bucket

Retrieving the bucket policy

PowerShell allows fetching the access policy of an S3 bucket, providing insights into who can access the data:

# Get the policy for a specific S3 bucket
Get-S3BucketPolicy -BucketName " snowcapcyber-bucket"

Checking bucket permissions

PowerShell scripts can assess and identify open or misconfigured access permissions on S3 buckets...
