Grand Theft Auto developer Rockstar Games has been targeted for a second time in three years by hackers.

The data breach affecting the gaming giant was reported by cybersecurity news outlets on Saturday, after a group of hackers claimed responsibility for the hack.

In posts viewed by outlets, the criminals said they gained access to Rockstar servers managed by a third-party cloud provider and would publish stolen material online unless paid a ransom.

But Rockstar, confirming the hack to gaming publication Kotaku, downplayed the breach - saying "this has no impact on our organisation or our players".

"We can confirm that a limited amount of non-material company information was accessed in connection with a third-party data breach," a Rockstar spokesperson told the outlet.
