Sony has discovered a file on its hacked servers named “Anonymous” containing the words “we are legion” and believe the hacker group is responsible for breaking into its servers and comprising personal information and data on 77 million PSN accounts that may have included credit card data.
The hacker group which has participated in cyber attacks that have shut down corporation’s and bank’s websites related to the Wikileaks scandal denied any involvement in the attacks.
Customers of Sony’s services may get freebies such as 30 free days of PlayStation Plus as well as a variety of free downloads to prevent customers from closing their accounts.
The company discovered an unauthorized intrusion into its servers on April 20, but didn’t notify customers until April to avoid “…confusion and lead [customers] to take unnecessary actions…”.
5.6 million customers of the Sony Playstation Network in the United States had stored credit card data on the company’s servers which Sony says was encrypted.
So far none of the credit reporting agencies are reporting any instances of fraud related to the attacks on Sony’s servers.
As of Wednesday, the company’s Facebook and other online game services have not been taken back online including the Playstation Network, which is what gamers use to communicate with each other and play together online.
PlayStation chief Kazuo Hirai told Congress in a letter related to the investigations of which Congress is also participating in:
“I am of course aware of the criticism Sony has received for the time taken to disclose information to our customers,” Hirai wrote. “I hope you can appreciate the extraordinary nature of the events the company was facing — brought on by a criminal hacker whose activity was neither immediately nor easily ascertainable.”
Patrick Seybold, Senior director of coporate communications for Sony wrote in a blog post:
“We will continue to keep you posted as we work to restore our network and provide you with both the entertainment and the security you deserve,” he wrote.
