Description

machscope is a macOS terminal-native tool designed to explore and correlate macOS internals such as processes, launchd jobs, Mach services, XPC services, code signatures, entitlements, and trust relationships. It consolidates information from various native macOS tools into a single, readable graph to aid in security triage, malware hunting, and debugging. The tool is dependency-free, written in Python, and leverages macOS native utilities. It surfaces trust and anomaly findings but does not itself represent a vulnerability or exploit. It is intended as a forensic and investigative utility rather than a security threat.

Built this during a long macOS internals investigation. It connects processes → launchd jobs → Mach services → XPC services → code signatures → entitlements → trust signals into one readable view.

Zero dependencies. Pure Python + macOS native tools (codesign, launchctl, otool, plutil).

Some things it answers: - What Mach services does this process expose, and who actually backs them? - Which launchd label owns this daemon, and is it signed by Apple or some random third party? - Are there suspicious mismatches between a binary's signature and the entitlements it demands? - What XPC services are embedded in this app bundle?

Would love feedback from other macOS CLI nerds.

Technical Analysis

machscope is a zero-dependency Python-based macOS tool that aggregates and correlates data from processes, launchd jobs, Mach services, XPC services, code signatures, entitlements, and Mach-O linkage into a single interrogable graph. It uses native macOS commands (ps, lsof, launchctl, codesign, otool, plutil) to provide a comprehensive view of the trust and relationship context of macOS binaries and services. The tool helps identify anomalies such as mismatches in code signatures and entitlements, suspicious launchd labels, and other trust signals. It is designed for security triage, malware investigation, and understanding macOS internals, but it is not a vulnerability or exploit itself.

Potential Impact

There is no direct security impact or vulnerability associated with machscope. It is a security tool intended to assist defenders and analysts in understanding macOS internals and trust relationships. It does not introduce risk or exploit any system weaknesses.

Mitigation Recommendations

No mitigation is required as machscope is not a vulnerability or threat. It is a legitimate investigative tool. Users should ensure they download it from the official repository to avoid tampered versions.
