Android users beware. A cloned version of Jay-Z's Magna Carta Holy Grail app was discovered by computer security company McAfee.

The app, which allows 1 million users to download Jay-Z's new album, had already been criticized over privacy concerns.

Rapper Killer Mike first raised this concern. He tweeted a screen shot of the app's terms and conditions, which include permission to "approximate network location", "precise GPS location", "prevent phone from sleeping" and to "modify or delete contents on your USB storage".

The hacked version, found in unofficial sites, contains a code that copies data about users' device to a server when the phone restarts.

The code also prompts users to download anti-government messages. In addition, the image of Barack Obama's "Hope" poster with the text "YES WE CAN" appears as the wallpaper on infected devices.

Jay-Z released his highly anticipated twelfth studio album last July 4 with a partnership with Samsung. It was reported that the mobile giant paid Jay-Z $5m for the rights to give away digital copies of Magna Carta Holy Grail.

Unfortunately, Jay-Z's app containing his music did not work on the day of the premiere and instead had its debut on the radio.

As of this time, neither Jay-Z nor Samsung has posted any official statement regarding the hacking incident.
