services / Azure / Storage account local users (SFTP)

A local user identity configured on an Azure Storage account for SFTP/blob access, with its own credentials (password / SSH keys / shared key) and permission scopes.

Grants data-plane access to blob/file data of a single storage account; a credentialed identity scoped to one organizational function.

Microsoft.​Storage/​storageAccounts/​localUsers/​regenerateSharedKey/​action

Regenerates and returns a new shared key for the local user, producing usable credential material that grants the attacker data-plane access while invalidating the legitimate user's existing key.

Risks

1. Cryptographic exfiltration (CRITICAL)
2. Lateral movement (BOOST)

Scope: HIGH

This privilege may grant access to sensitive data from a single organizational function, or allow interruption of a service supporting a single organizational function.
