Azure Blob Storage Misconfigurations: Attacker’s Gateway to Data

Azure Blob Storage containers can be misconfigured to allow anonymous public access, exposing sensitive files without authentication. This walkthrough demonstrates how to intentionally set up a vulnerable Blob Storage container with container-level anonymous access, then use the MicroBurst PowerShell toolkit to enumerate storage accounts and discover exposed containers. The post also covers manual enumeration using the Azure Blob REST API query parameter `?restype=container&comp=list`. Such misconfigurations can lead to data breaches, PII exposure, and lateral movement within cloud environments.
