Galaxy Note 2 Security Flaw In Homescreen

10:07 AM

Note: If this tutorial worked for you (and it should work), please leave a comment below. Thanks.

Samsung’s Galaxy Note 2 is one fine looking tablet, and no doubt it has sold millions across the globe (and will continue to do so, at least until the Galaxy Note 3 or its successor is released), but having a great design is not all there is to a smartphone. Terence Eden has discovered a security flaw in the homescreen, allowing you to run apps as well as dial numbers even when the Galaxy Note 2 which runs on Android 4.1.2 Jelly Bean is locked.

This particular attack is super effective (in Pokemon parlance) against Pattern Lock, PIN, Password, and Face Unlock, without any known method, according to Mr. Eden, to prevent your homescreen from being accessed. Being on Santa’s naughty list this year is going to be easy as long as you follow the following steps, taken verbatim from Mr. Eden’s blog.
  • 1. Lock the device with a "secure" pattern, PIN, or password.
  • 2. Activate the screen.
  • 3. Press "Emergency Call".
  • 4. Press the "ICE" button on the bottom left.
  • 5. Hold down the physical home key for a few seconds and then release.
  • 6. The phone's home screen will be displayed - briefly.
  • 7. While the home screen is displayed, click on an app or a widget.
  • 8. The app or widget will launch.
  • 9. If the widget is "direct dial" the phone will start ringing.
Of course, this attack is not that “destructive” when you think about it, whether it is making a phone call depending on a direct dial widget’s availability on the homescreen or to allow the attacker to check out what kind of apps that you have there, but still, a security vulnerability or risk such as this should not be there in the first place.
