Earlier this week we found out that tons of Samsung devices including the Galaxy S III were vulnerable to a very simple hack that could hard reset the phone.

The hack essentially required a simple html file that ran a TEL url with the reset code for the phone.

A bunch of Android based devices dialed the USSD code without confirming from the user resulting in data loss.

Collin Mulliner has released a simple app named TelStop that can save you from such attacks.

The app simply registers as a URL handler for TEL links. So whenever a malicious code is processed by the phone’s browser, user gets the popup to select between the dialer and the TelStop app.

This is a pretty simple approach to stop the hack from hard resetting vulnerable devices. It is not a permanent solution though. It remains to be seen if manufacturers would roll out patches for all the affected models.
