Why It Matters ​

Camera capture from a shared hook is spyware-like behavior because it can silently collect sensitive imagery from the developer environment.

What Triggers ​

SEC711 matches executable hook lines that invoke explicit camera capture utilities such as imagesnap, fswebcam, or ffmpeg with camera-oriented selectors like video=, /dev/video, -f v4l2, -f video4linux2, webcam, or camera.

False Positives ​

Shared committed hooks should not activate a developer's camera. Any legitimate capture should be explicit, local-only, and initiated by the user.

Remediation ​

Remove camera capture behavior from the shared hook and require deliberate user-driven capture outside committed automation.
