MacOS Injection via Third-Party Frameworks

This report details PoC techniques for macOS post-exploitation: leveraging .NET Core’s debug transport named pipes to perform remote process memory read/write and code injection into signed/hardened processes, and abusing Electron’s ELECTRON_RUN_AS_NODE environment variable to execute Node code under a signed app and inherit TCC/privacy permissions (demonstrated by injecting an Apfell implant). The author documents discovery, PoC code, and mitigation-relevant observations.
