Camoscope

Camoscope is a macOS command-line interface tool designed to identify application windows that might be hidden or concealed from screen sharing. Key capabilities include: • Flags hidden-from-capture windows • Verifies owning process and code-signing metadata • Optionally inspects hidden application text via Accessibility • Provides behavioral signals, not just blocklists This utility inspects the macOS WindowServer sharing state to highlight windows that warrant further investigation. It moves beyond simple product-name blocklists by focusing on behavioral cues, providing a more robust detection mechanism. For any flagged windows, Camoscope can display the owning process and relevant application or code-signing metadata, aiding users in understanding what is actively running. With explicit Accessibility permission, Camoscope offers the option to inspect text exposed through the macOS Accessibility tree, offering deeper insights into concealed application content. It's important to note that Camoscope delivers system signals for review, not a definitive verdict on screen-share visibility or misconduct. The output serves as a starting point for investigation. Camoscope is ideal for use in technical interviews or assessments, where a participant can run it locally on their Mac, with full consent, to review or share the results. This ensures transparency and helps maintain interview integrity by checking what a candidate's screen share may inadvertently or intentionally omit.
