An autofattura is a self-issued invoice created by the seller or recipient in specific regulated cases, such as when ordinary invoicing is not possible or when tax rules require a special documentation path. It is not a payment record; it is a bookkeeping document that formalizes a transaction for accounting and tax compliance.
In cyber security, autofatture matter because they live inside digital finance and ERP workflows. If an attacker can alter invoice data, create fake documents, or bypass approval steps, the result can be fraud, tax exposure, or loss of audit integrity. Defenses include role-based access control, signed records, immutable logs, and checks that match the invoice to the underlying sale or service. In practice, the autofattura is a control point: it helps preserve a trustworthy trail when normal transaction data are incomplete or require correction.
