As reported in Naked Security, three Georgia Tech students hacked the mobile app ‘Yo,’and then reported their feat to TechCrunch.
We can get any Yo user’s phone number (I actually texted the founder, and he called me back). We can spoof Yo’s from any users, and we can spam any user with as many Yo. We could also send any Yo user a push notification with any text we want (though we decided not to do that).
Users were greeted with this message:
The founder of Yo, Or Arbel, confirmed the problem and fixed it, and then hired one of the young men. This has to be one of the most interested job interviews that I have ever heard about, but it certainly is a way to “stand out from the crowd.”Share
