+<overview>
+<p>Broadcasted intents in an Android application are visible to all applications installed on the same mobile device, exposing all sensitive information they contain.</p>
+<p>Broadcasts are vulnerable to passive eavesdropping or active denial of service attacks when an intent is broadcasted without specifying any receiver permission or receiver application.</p>
+</overview>
+
+<recommendation>
+<p>Specify receiver permission or specify receiver application in broadcasted intents, or switch to <code>LocalBroadcastManager</code> or the latest <code>LiveData</code> library.</p>
+</recommendation>
+
+<example>
+<p>The following example shows two ways of broadcasting intents. In the 'BAD' case, no "receiver permission" is specified. In the 'GOOD' case, "receiver permission" is specified.</p>
