Hapara Lock Screen Bypass

The Exploit

Hapara's student monitoring system has a vulnerability that can be exploited through careful manipulation of the browser's interface elements. This method takes advantage of timing and UI glitches to bypass the lock screen.

Step-by-Step Instructions

1. Preparation: Make bookmarks of pages you want to visit beforehand. This is crucial as you'll need quick access to them during the bypass process.
2. Trigger the UI: Once your screen is paused by Hapara, repeatedly attempt to unfullscreen your browser (typically F11 key or the fullscreen button). Each time you do this, you might briefly see your tabs and bookmark bar reappear.
   
   Attempt to right-click on the bookmarks bar until a context menu shows up. This may take several attempts due to the screen locking.
3. Create a Folder: In the context menu that appears, select "Add folder". Name it anything you like and click "Done". If successful, your tabs and bookmarks should remain visible at the top of your screen.
   
   If it doesn't work on the first try, repeat the process until the UI elements stay visible.
4. Bypass the Lock: Once the tab and bookmarks bar remains visible, rapidly click one of the bookmarks you prepared earlier. This creates enough browser activity to lag Hapara into displaying your page instead of the pause screen.
   
   As soon as your page fully loads, turn off your WiFi. This stops data flow between your computer and the teacher's dashboard, preventing them from re-pausing your screen.

Important Notes

This method works due to a timing vulnerability in how Hapara handles UI interactions. The system is designed to lock the screen but doesn't fully prevent all browser interactions when exploited in this specific way.

Success rates may vary depending on your specific device, Chrome version, and Hapara implementation. The technique requires precise timing and may take several attempts to execute successfully.
