macOS relies on strict process isolation to enforce system integrity protection, privacy controls and entitlement boundaries. A single entitlement misconfiguration undermines that foundation by allowing arbitrary process memory access on fully protected systems, enabling extraction of login keychain secrets, bypass of transparency, consent and control safeguards, and decryption of FairPlay-protected iOS applications on Apple silicon Macs.

This session illustrates how narrowly scoped system privileges become systemic risk when applied to widely accessible binaries, converting read-only process access into broad privacy and security compromise.

In this session, led by Koh Nakagawa, security researcher at FFRI Security, you will learn:

• Why read-only task access enables keychain extraction and privacy control bypass despite system integrity protections;
• How entitlement drift in widely accessible binaries creates zero-day exposure across macOS security boundaries;
• Detection opportunities using endpoint security telemetry to identify similar entitlement misconfigurations before exploitation.
