But now there's an even easier hack that affects all devices running Google Wallet, whether they're rooted or not. TheSmartphoneChamp discovered a vulnerability that's almost too easy to perform. It gives the hacker access to the funds on your prepaid Google card.
If your phone is lost, all a thief has to do is go into the Google Wallet app's settings and clear the data. When the app is relaunched, the PIN can be reset, providing full access to your account.
