Guides and research on misconfigured cloud storage: how exposures happen, how to find them, and how to lock them down.
29 daily aggregate observations from the Misconfigured.app index, with downloadable data, methodology, and limits on interpretation.
A cross-provider checklist for remediating open buckets: inventory, disable public access, audit ACLs and IAM, rotate exposed secrets, enable detection, and use signed URLs.
How B2's allPublic bucket type exposes every file to unauthenticated callers, the S3-compatible listing surface, why teams flip allPublic for free Cloudflare egress, and how to remediate.
Why point-in-time fixes regress and how to prevent drift: AWS Config rules, CloudTrail alerts, Azure Policy, GCS org policies, and continuous external brand-asset monitoring.
How DigitalOcean Spaces and Wasabi share the S3 ACL and listing surface, how the Spaces File Listing toggle exposes buckets, and how to lock them down with private ACLs and signed URLs.
The real discovery vectors for cloud storage bucket names: naming conventions, permutation tools, public indexes like GrayhatWarfare, JS bundles, git history, and DNS CNAME hints.
The real attack progression: enumeration to credential extraction to lateral movement, the underappreciated risk of anonymous write, and why no access logs does not mean no access.
How Firebase Realtime Database .read: true and Storage allow read: if true expose data to anonymous callers, the auth != null cross-tenant pitfall, and how to lock rules down.
How Azure Blob containers become publicly readable, how to detect anonymous access via the ?restype=container&comp=list probe, and how to lock it down with SAS tokens.
How allUsers and allAuthenticatedUsers IAM bindings make GCS buckets publicly accessible, the difference between UBLA and legacy ACLs, and how Public Access Prevention blocks re-exposure.
How S3 buckets become public, how to check if one is exposed, the real risk, and how to lock it down with Block Public Access.
