Yo took the industry by surprise with one of the simplest apps to appear in the Google Play Store. In essence, it’s nothing but a tool to send a message to your contacts, with a colorful and simple-to-use interface that will confuse no one. You can’t send any message, either… just “Yo”.

It somehow got a million dollars in funding and is constantly growing. As with any popular app, it is bound to get hackers’ attention, and that it did. Some amazing things can be accomplished from the comfort of a dorm room, Yo’s hack being the latest one.

Three Georgia Tech students have managed to tap into Yo’s systems and are able to take some crazy actions. For such a simple and single-purposed app, these hackers accomplished quite a bit. The hacker has contacted Tech Crunch with some revealing, and worrisome, information.

“We can get any Yo user’s phone number (I actually texted the founder, and he called me back). We can spoof Yos from any users, and we can spam any user with as many Yos as we want. We could also send any Yo user a push notification with any text we want (though we decided not to do that).” -Hacker

Some proof of hacks has shown up across the web; a Vine video and an Instagram post being the most popular.

Or Arbel, Yo’s founder, has gone on the record about this, simply saying the app has “security issues”. The company seems to be taking the matter rather seriously, as they should. The problem was said to be fixed very soon, so chances are you won’t be seeing these issues anymore. At least not for a while, that is.

Let’s hope this doesn’t happen again. Such an innocent and simple app can turn into a mess very soon.

    As stupid as this app is, it did not deserve to be hacked. The real people harmed are Yo users, and so it is not fair that they get a lot of their info stolen.
    It is a point though that they were stupid enough to get the app, but let’s not go there :)

      True. The guys that found it sent everything to the dev though

    • Because of all the stupid media attention like this one.
