## Overview

The macOS version of the DigiD app is not signed with Hardened Runtime. As a result, a local process can load its own dylib into DigiD via DYLD_INSERT_LIBRARIES.  An attacker with local user-level code execution can execute arbitrary code within the macOS version of the DigiD app, thereby gaining access to DigiD data and cryptographic capabilities that the process normally does not have.
