OverSight monitors a mac's mic and webcam, alerting the user when the internal mic is activated, or whenever a process accesses the webcam.
compatibility: OS X 10.10+ current version: 1.2.0 (change log) zip's sha-1: adae7e8a2d4f78489205d6b0c3017c3ebf733f6f One of the most insidious actions of malware, is abusing the audio and video capabilities of an infected host to record an unknowing user. Macs, of course, are not immune; malware such as OSX/FruitFly, OSX/Crisis, OSX/Mokes, and others, all attempt to spy on Mac users. OverSight constantly monitors a system, alerting a user whenever the internal microphone is activated, or the built-in webcam is accessed. And yes, while the webcam's LED will turn on whenever a session is initially started, new research has shown that malware can surreptitious piggyback into such existing sessions (FaceTime, Skype, Google Hangouts, etc.) and record both audio and video - without fear of detection.
As with any security tool, direct or proactive attempts to specifically bypass OverSight's protections will likely succeed. Moreover, the current version over OverSight utilizes user-mode APIs in order to monitor for audio and video events. Thus any malware that has a kernel-mode or rootkit component may be able to access the webcam and mic in an undetected manner.
To install OverSight, first download the zip archive containing the application. Depending on your browser, you may need to manually unzip the application by double-clicking on the zipped archive: Then, simply double-click on 'OverSight_Installer.app'. Click 'Install' to install the tool: OverSight can also be installed via the command-line. Just execute the installer application with the -install flag:
//install $ sudo OverSight_Installer.app/Contents/MacOS/OverSight_Installer -install OVERSIGHT: install ok! Once OverSight is installed, it will be running and is set to automatically start each time you log in. By default, when running OverSight adds an icon () to the status menu. Clicking on this icon will display a menu with various information and configuration options: While OverSight is running, anytime the internal microphone is activated, or a process accesses the built-in webcam, OverSight will alert you of this fact. Below is an example of an OverSight mic alert, generated when an application (Shazam.app) has activated the internal microphone: Besides alerting that the mic has been activated, the alert contains the name and process identifier of the process responsible for the alert (i.e. 'Shazam'). Moreover, the notification allows one to either 'allow' the process, or terminate it via the 'block' option. If the 'allow' option is selected, a popup will be displayed asking if the process should be allowed always, or just this once: Clicking the 'Yes, Always' will 'white-list' the application - meaning that in the future no OverSight alert will be displayed; the application will be automatically allowed. White-listed applications can be viewed via OverSight's preferences pane (discussed below): When OverSight detects that the webcam has been activated, or, that a secondary process has accessed the camera (while it's already in use) it will display an alert: The webcam notifications will contain the name of the process (i.e. Facetime) and its process identifier. Just like with the mic notification, it will also contain the 'allow' or 'block' options. Note, in some cases OverSight cannot identify the process responsible for activating the mic or webcam. When this (rarely?) occurs, a more generic alert will be shown. For example, a mic activation alert: In order to configure OverSight, simply click on its icon () in the status menu. Then click on 'Preferences': This preferences window will also be shown if you run OverSight.app from the /Applications folder.
To uninstall OverSight, re-run 'OverSight_Installer.app' (you can re-download it if needed). Clicking the 'Uninstall' button will both stop and remove OverSight from your Mac: OverSight can also be uninstalled via the command-line. Just execute the installer application with the -uninstall Is There A Camera App For Mac Os X 10 11 Download Free![]()
//uninstall $ sudo OverSight_Installer.app/Contents/MacOS/OverSight_Installer -uninstall OVERSIGHT: uninstall ok! To manually uninstall OverSight, first stop it (via the 'Quit' menu option), then delete the 'Oversight.app' from the /Applications folder. Then delete the login item (System Preferences, Groups & Users -> Current User -> Login Items). Finally delete the ~/Library/Application Support/Objective-See/OverSight/ directory. Is There A Camera App For Mac Os X 10 13 DownloadComponents/Capabilities/FootprintsThe following table briefly summarizes OverSight's components, capabilities, and system footprint:
In terms of networking code, each time OverSight starts, it queries https://objective-see.com/products/versions/oversight.json to see if there is a new version of the tool. This can be disabled via the 'Automatically check for updates' option in OverSight's preferences pane. Other than this simple version check, it contains no other networking capabilities. FAQs Q: Why does the OverSight Installer need my password? A: In order to determine what process(es) is/are using the webcam, OverSight interfaces with Apple's 'camera daemon.' This requires elevated privileges. Also if the user clicks, 'block' when a process is detected using the camera, OverSight will terminate the process. Again, this action (may) require elevated privileges. Q: How can I tell if OverSight is installed and running? A: When started, OverSight adds an icon () to the status menu. The presence of this icon, indicates that the process is running (unless you've told it to run in 'headless' mode). One can also check if it's running, via the Activity Monitor.app. Select View->All Processes, and look for a running process named OverSight_Helper Q: Why does it take OverSight, a few seconds to display the webcam/mic usage notification? A: There is not easy way to determine what process is using the webcam or mic, when either is activated. Worse, there is no direct indication that a new process is accessing an existing a webcam session. Thus OverSight has to perform various tests and has to poll the system (only when the camera/mic is active) in order to determine what process(es) is/are accessing the device. This takes a few seconds..mahalo for your patience! Q: Why can't OverSight detect what process is using the mic/webcam? ![]() A: While there is no direct way to determine what process is using the webcam or mic, OverSight can almost always figure this via indirect means. If it fails to identify any process (but can still detect that the webcam/mic was activated), Oversight will still generate a notification stating the device was activated. However, this notification will not contain any process information, nor of course, the ability to 'allow'/'block' the process. Q: How is OverSight different than other tools (such as MicroSnitch)? A: OverSight is unique in a variety of ways:
