Find exposed data in Azure with public blob scanner



Find exposed data in Azure with this public blob scanner


A 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:


BlobHunter helps you identify Azure blob storage containers which stored files that are publicly opened to everyone over the internet.
It can help you check for poorly configured containers storing sensitive data.
This can be helpful on large Azure subscriptions where there are lots of storage accounts that could be hard to track.
BlobHunter produces an informative csv result file with important details on each publicly opened container in the scanned environment.
