TL;DR: A Microsoft Azure storage shared-key flaw can expose organizational secrets, enable lateral movement, and even support remote code execution when attackers abuse storage account access and managed identities, according to Entro Security’s analysis. The issue shows that secrets management must account for trust boundaries, not just secret storage.
NHIMG editorial — based on content published by Entro Security: Don’t let this Azure vulnerability expose your organization’s secrets
By the numbers:
- 44% of NHI tokens are exposed in the wild, being sent or stored over platforms like Teams, Jira tickets, Confluence pages, and code commits.
Questions worth separating out
Q: What breaks when storage account keys can influence workload identity?
A: The boundary between data access and privilege control breaks down.
Q: Why do shared keys create more risk than scoped authentication in cloud storage?
A: Shared keys concentrate authority into one credential that often outlives the original task and can affect multiple actions.
Q: What do security teams get wrong about managed identities in Azure?
A: They often assume managed identity removes the need to govern the execution path around it.
Practitioner guidance
- Disable shared key authorization where feasible Prefer Azure Active Directory authentication for storage access and remove any reliance on account-wide shared keys for normal operations.
- Separate function code from token-bearing storage paths Ensure that contributors who can manage storage content cannot alter files that the runtime uses to bootstrap or retrieve privileged identity material.
- Map every workload identity to its writable dependencies Identify which storage accounts, deployment paths, and configuration stores can indirectly influence a managed identity token or execution context.

- The specific Azure storage and function workflow that lets a contributor role pivot into credential theft
- Microsoft's recommended mitigation path for shared key authorization and Azure Active Directory authentication
- Implementation context for secrets discovery, vault coverage, and anomaly monitoring across cloud-native estates
- Practical examples of how laterally moved identities can be detected before destructive actions begin

Shared key authorization is a standing privilege problem disguised as convenience. The article shows that one storage credential can authorize configuration changes, data access, and downstream token abuse. That is not a narrow secret management issue but a trust-boundary failure in cloud IAM design. Practitioners should treat any shared key that can influence runtime or configuration as a high-risk standing privilege.
A few things that frame the scale:
- 91% of former employee tokens remain active after offboarding, leaving organisations vulnerable to potential security breaches, according to The 2025 State of NHIs and Secrets in Cybersecurity.
- Our research also found that 62% of all secrets are duplicated and stored in multiple locations, which increases accidental exposure and complicates ownership across cloud and collaboration tools.
A question worth separating out:
Q: Who is accountable when a storage-backed function exposes higher-privileged credentials?
A: Accountability sits across cloud platform, application, and IAM teams because the failure crosses access, runtime integrity, and secret governance. The right control model assigns ownership to the workload path, the storage resource, and the identity issuer rather than treating the incident as a single-team problem.
