OurMine claimed responsibility for the hack, which was spotted after the group managed to post some benign video clips.
The team also tweeted at 2:50 AM ET today saying "Hey, its OurMine,we are testing your security," with a link to their website that promotes and sells its own "services" for which it has already made $16,500.
Although the tweets posted by the group did not contain any harmful content, both the tweet and linked to a short Vine video clip have immediately been removed.
