The so-silly-it's-not-worth-mocking app Yo was hacked by some college students. Caveat downloader. The texting app does nothing but ping your friends with the word "Yo." It has reportedly netted $1 million in funding already, from high-profile investors, and has about a quarter million users as of today.
A Georgia Tech student told TechCrunch it was very easy to hack: he and two bros claim to have accessed and spammed Yo user phone numbers, sent push notifications, and swapped other words for "Yo."
Or Arbel, Yo's creator, confirms that Yo was, yes, having "security issues."
