Sony Corp. this week said it estimates the restoration of the Playstation Store of the Playstation Network division by the end of May.
A previous report targeted a May 24 return.
The Playstation Store has been unavailable following an external intrusion that resulted in the shut down of the Playstation Network and Qriocity services last month.
Sony May 15 restored the Playstation Network division in the U.S.
In addition, the service was restored in the UK, Ireland, Middle East, New Zealand, Australia, Mexico and South America .
Restoration includes sign-in to the Playstation Network and Qrocity division, including password reset; restoration of online gameplay across the PS3 and PSP; playback of rental video content; access to third-party services like Netflix and Hulu; Friends functionality, and Playstation Home.
The company said it has implemented new and additional security measures, including updating and adding advanced security technologies, additional software monitoring and penetration and vulnerability testing, and increased levels of encryption and additional firewalls.
The new Firmware 3.61 is a mandatory update that will require PSN users to change their password prior to login of the network.
The company expects to have service fully restored by the end of May.
Access to the Playstation Network and Qrocity divisions has been crippled since Apr. following an external intrusion that compromised consumer data.
The company said it is taking steps to prevent future attacks, including enhanced levels of data protection and encryption; enhanced ability to detect software intrusions, unauthorized access and unusual activity patterns; additional firewalls; establishment of a new data center in an undisclosed location; and the naming of a new Chief Information Security Officer.
