Sony Fined over 2011 PlayStation Cyberattack

Regulators in the U.K. have fined Sony Corp.'s U.K. unit 250,000 pounds ($394,100) for failing to prevent hackers from attacking its PlayStation Network.

The U.K. Information Commissioner's Office said Sony could have prevented the breach.

"If you are responsible for so many payment card details and log-in details then keeping that personal data secure has to be your priority," David Smith, ICO's deputy commissioner and director of data protection, said in a statement. 

"In this case that just didn't happen, and when the database was targeted – albeit in a determined criminal attack – the security measures in place were simply not good enough."

The April 2011 attack compromised more than 100 million customer accounts.

Sony suspended the related services in July and budgeted 14 million yen ($155 million) in costs that year.

Sony has said it will appeal the decision.
