Enabling DOM clobbering

To avoid interfering with your target site's functionality, DOM clobbering is disabled by default. To enable these checks:

  1. Go to the DOM Invader settings menu.

  2. Under Attack types, toggle the switch so that DOM clobbering is on.

  3. Click Reload to refresh the browser. This is necessary for your changes to take effect.
