Chat app Yo has been hacked by three Georgia Tech students, just days after its meteoric rise on social networks, websites and blogs across the United States.
The content-free app, which strictly allows you to send the word "Yo" to your friends, had been downloaded more than 100,000 times and reached the U.S. App Store top 10 list this week.
Or Arbel, Yo's Israeli founder, confirmed that "some of the issues have been fixed and we are still working on the others."
Arbel added that he could not reveal any specific information about the hack "to prevent misuse of this information, but [Yo] brought in a specialist security team to deal with the issues."
Since launching on April 1, Yo has raised over $1 million in venture capital funding. Arbel and Yo additionally plan on launching a programming interface so developers can integrate with the app.
