Japanese game developer Square Enix Holdings said email addresses of 25,000 customers as well as resumes of 250 job applicants were leaked after a hacker attack against its European subsidiary.
Hackers accessed the Eidosmontreal.com website, managed by London-based Square Enix Ltd, as well as other product sites, said a statement from the group released late Saturday.
The news came as Sony's game and Internet services were pulled down after hackers staged one of the biggest data breaches since the advent of the Internet, including the theft of personal customer data.
"No dissemination or misappropriation of any other personal information has been identified at this point," the Tokyo-based firm said.
The attacked websites and services do not hold any credit card information or personal code data, the company added.
