Google late Friday night disabled the ability to provision new Google Preaid Cards, fallout from the discovery of a flaw in the Google Wallet app. The gist is that if someone were to find your phone, they could reset the Google Wallet PIN and gain access to your Google Prepaid Card. In a separate incident, rooted phones were found to be vulnerable to a brute-force crack.
And so, Google has temporarily disabled provisioning of prepaid cards as an interim step, and it says it will have "a permanent fix soon."
Google also reminds us that rooted devices are by definition not as secure as un-rooted phones and "we strongly discourage [rooting] if you plan to use Google Wallet because the product is not supported on rooted phones."
In addition, Google provides toll-free phone support 24 hours a day if you have concerns or questions about Google Wallet. In other words, just like with a traditional credit card, call if you lose it. Or have issues. Or just need a friend.
