Yesterday we wrote about Yo, the messaging app which has become inexplicably popular over the past month, and has netted $1.2 million in venture funding.

Less than 24 hours later it seems that Yo has hacked by a Georgia Tech student, together with two of his room mates. The hack allows for them to access any Yo user’s phone number, spoof Yo messages from any user, spam users with multiple messages, and even send push notifications featuring any text they want. Another hack appears to let hackers Rickroll users with the infamous Rick Astley song.

Yo founder Or Arbel has confirmed to TechCrunch that the service has been hacked, and notes that, “We are taking this very seriously.”

While some security issues have supposedly been fixed, others are still live. He says that the company has brought in a specialist security team to deal with the issues, and that they should be fixed “in next few hours.”

Although I wouldn’t recommend it until the app is fixed, Yo can be downloaded from the App Store, available for all iOS devices running iOS 5.0 and above.

    Really, taking security seriously? It seems that they didn’t when they wrote the code, only after they got bad PR.
