"I know this has been a frustrating time for all of you," Stringer said in comments posted on Sony's U.S. PlayStation blog. "To date, there is no confirmed evidence any credit card or personal information has been misused, and we continue to monitor the situation closely," he said in a statement dated May 5.
Stringer said they would restore network services soon, but gave no date.
"We are also moving ahead with plans to help protect our customers from identity theft around the world. A program for U.S. PlayStation Network and Qriocity customers that includes a $1 million identity theft insurance policy per user was launched earlier today and announcements for other regions will be coming soon," he said.
Stringer has faced harsh criticism of his leadership after Sony revealed hackers had stolen the data of more than 100 million accounts. Kazuo Hirai, his likely successor, led a news conference and apology on Sunday.
