Yo! Remember the hit new app that managed $1 million in funding we covered yesterday, which enables smartphone owners to send "Yo" alerts to contacts? The service has been hacked by a student and two roommates. Yo has confirmed they're investigating the hack and expect to have the security vulnerability patched in the "next few hours". The hackers have been able to access any Yo user's mobile number with the ability spam any user with multiple Yo messages.

The hackers opted not to spam users of the Yo service, but (if the apps weren't already pointless enough) users have reported to receiving a Yo through the app which played a snippet of Rick Astley's "Never Gonna Give You Up". It's unsure whether this is related to this security hack or another bug in the service exploited by others. Unfortunately, the founder of Yo failed to specify which hacks were still active.

Should you be actively using the apps, you'll be pleased to learn the team is working on patching everything up.
