PlayStation Network 'back up soon'

Sony says it aims to fully restore its PlayStation Network, shut down after a massive security breach, by the end of May.

Satoshi Fukuoka, a spokesman for Sony Computer Entertainment, said a probe into a recent hacker attack on the network was continuing, but declined to give details.

Sony shut down the network, a system that links gamers worldwide in live play, on April 20 after discovering the security breach.

Sony said the network intrusion had compromised personal data from more than 100 million online accounts.
