TOKYO — Sony on Sunday said it would "shortly" begin restoring its PlayStation Network and Qriocity online services following a major security breach that compromised millions of users.

The Japanese entertainment and technology giant also announced new security steps while adding that it so far had no evidence that credit card data was stolen, but could not rule out the possibility.

"This criminal act against our network had a significant impact not only on our consumers, but our entire industry," said Kazuo Hirai, Sony executive deputy president.

"These illegal attacks obviously highlight the widespread problem with cyber security. We take the security of our consumers' information very seriously and are committed to helping our consumers protect their personal data."

Sony said it had worked with security firms and "implemented significant security measures to further detect unauthorized activity and provide consumers with greater protection of their personal information" and would create a new security officer position.
