BlobHunter is an opensource tool for scanning Azure blob storage accounts for publicly opened blobs.
BlobHunter is a part of “Hunting Azure Blobs Exposes Millions of Sensitive Files” research:

Overview
BlobHunter helps you identify Azure blob storage containers which store files that are publicly available to anyone with an internet connection.
The tool will help mitigate risk by identifying poorly configured containers that store sensitive data, which is specifically helpful in larger scale Azure subscriptions where there are a significant number of storage accounts that could be hard to track.
BlobHunter produces an informative csv result file that provides important details on each publicly opened container in the scanned environment.
