Odds are your Android device is susceptible to the Stagefright vulnerability. tches have only gone out for Nexus devices a few Samsung models on Sprint so far.

But if you really want to be sure, you can grab an app from Zimperium bs, the organization responsible for uncovering Stagefright.

en you download launch the app, it pulls up a list of the specific CVEs (common vulnerabilities exposures) that impact your phone.

Of course, if you’re susceptible ( unless you’ve applied the patch, you are) Zimperium throws in a “Contact Us” button to give out your email address, phone number, other details that would presumably give Zimperium a method to reach out to you. For what reason, they don’t say.

This other issues were noted in the comments, with some complaining that they had just installed Sprint’s patch for their Samsung device, yet they were still told they had the vulnerability. So perhaps the patch didn’t work, or Zimperium may just be checking the device information against its database, which hasn’t yet accounted for the new patches.

The story behind the story: Stagefright is likely the most significant vulnerability to hit Android. However, it’s spurred , Samsung, to take unprecedented steps to issue regular security updates. If the major Android players can follow through, if carriers don’t get in the way, it could mean a much safer ecosystem for everyone.
