Sony yesterday said its websites in three countries had been hacked, including in Greece where 8,500 user accounts had been compromised, adding it did not think credit card data had been stolen.

It said that on Sunday it discovered the security breach on its Greek Sony Music Entertainment website and immediately stopped the service, which remains shut down.

The Japanese entertainment and technology giant said it also discovered on Saturday that a page on its Indonesian website had been altered.

It also said its Thai unit’s website had been subjected to unauthorized access and was possibly used in a phishing attack.

News of the latest breach comes as Sony tries to recover from an earlier massive online hacking attack involving the theft of personal data including names, passwords and addresses from more than 100 million accounts on its PlayStation Network and Sony Online Entertainment services.

Sony shut down the PlayStation Network and Qriocity services on April 20. The company has said it cannot rule out that millions of credit card numbers may have been compromised.

On Monday Sony said it expected to post a $3.2 billion net loss for the fiscal year ended March as it tries to recover from the impact of the March 11 earthquake and tsunami, which ravaged production and damaged facilities.

It said the data breach will result in at least a $170 million hit in “currently-known costs” to operating profit this financial year in terms of insurance and damages.

Sony has said it plans to fully restore PlayStation Network and Qriocity services by the end of the month.
