Sony said hackers have attacked websites affiliated with the company in Canada and Thailand.

Intruders accessed data, including names and e-mail addresses, on about 2,000 customers via the Sony Ericsson Mobile Communications Canadian website. The site has been taken down, spokesman Atsuo Omagari said.

Sony detected the attack yesterday, a day after uncovering an intrusion into a website in Thailand, he said. The company is also investigating possible breaches at websites in Japan and Indonesia, he said.

Sony said yesterday intruders accessed a unit's website in Greece, compromising the information of about 8,500 customers, days after online-service unit So-net Entertainment Corp said a breach led to the misuse of user names and passwords of 128 customers.

The incidents follow last month's attack that hacked into more than 100 million user accounts of the company's PlayStation Network and Qriocity entertainment services.

"Sony is investigating whether the attacks discovered this week are related to each other," Mr Omagari said. "Sony hasn't found evidence to link those attacks to last month's intrusion into the PlayStation Network."

The company, which posted its biggest annual net loss in 16 years in the 12 months ended March 31, said this week the breach at the PlayStation Network may erode operating profit by 14 billion yen ($17 million) this fiscal year.

The PlayStation Network and Qriocity entertainment services went back online in the US and other regions excluding Asia on May 15th, more than three weeks after it suspended services. The company plans to fully resume the services by the end of this month.

Sony hired three security firms to investigate the attack and is working with law enforcement officials.
