darthcamaro writes "Last week, Rain Forrest Puppy (aka Jeff Forristal) first disclosed the initial public report about an Android Master Key flaw. Code was released earlier this week for attackers to exploit the flaw — but what about users? Google has claimed that it has patched the issue but how do you know if your phone/carrier is safe? Forristal's company now has an app for that. But even if your phone is not patched, don't be too worried that risks are limited if you still to a 'safe' app store like Google Play. 'The only way an Android user can be attacked via this master key flaw is if they download a vulnerable application. "It all comes down to where you get your applications from," Forristal said.'"
