French DJ David Guetta has spoken about having to hire a former Pentagon investigator to look into his online security after a version of his new single was stolen by hackers before it was released.

David Guetta said that an unfinished a capela version of his single Where Them Girls At featuring Flor Rida and Nicki Minaj was stolen after his computer was hacked in to. The single was then transformed into a “bad” version and was put out on the internet under his name.

Security is now a big issue for David Guetta: “It's a big worry. We have hired a guy who works with security for the pentagon.”

To rectify, the real version of the single has now been released by his record label and is already at number one on the iTunes chart despite its unplanned early release.

The DJ explained how the single managed to be stolen: “Usually inside the studio there's a Wi-Fi connection so between the engineer and the artist we can send tracks to work. They (the hackers) would be outside in a car.

“We have to have a real specialist because it's really crazy because every artist has huge problems. Our job as producers is to make the music sound as good as possible. If you put a demo on the net and people say it was the finished version then they are going to say it sucks. I really hate that.”

he added that hackers had tried to trick him the past to try and steal studio work: “I don't answer these emails anymore but one day as I was working with Usher I had a message from his engineer – it's impossible for anyone normal to know the name of Usher's engineer. He was saying “hey it's me I need you to down load these vocals” then if you give a code they break into your computer – this kind of thing.”
