Attention iPhone owners: If you don't have the free Find My iPhone app that allows you to track down your lost phone and wipe it clean if it's irretrievable, let this video be a motivating force. Researchers at the Fraunhofer Institute Secure Information Technology found a way to jailbreak any iPhone and retrieve passwords from the phone's keychain—like ones for e-mail, wi-fi networks, banking apps, corporate VPN—in just six minutes. Even scarier is that the tools they used are widely available, so anyone with a little know-how can do it. Next time you lose your phone, take our advice—wipe it down.
