Storage account allows anonymous blob access
Subscription: Production · East US
The storage account acmestorageprod001 allows anonymous public access (allowBlobPublicAccess=true). Any folder inside it can be opened up to the entire internet — no password needed, and nothing in your logs when it happens.
Fix path
Set allowBlobPublicAccess to false at the account level. Portal: Storage account → Configuration → Allow Blob anonymous access → Disabled → Save.
Attacker’s View™
Attackers run automated tools that guess storage account names around the clock — every account has a public web address, whether you use it or not. With anonymous access allowed, any folder marked public can be downloaded by anyone, leaving no trail. Several high-profile 2024 leaks — including 43 TB of Microsoft’s own AI research data — started exactly this way.
