Sony has come forward with an update on the PlayStation Network security breach that left 77 million accounts compromised, announcing that services will resume this week.

Earlier today, PlayStation boss Kaz Hirai took to the stage in Tokyo to address concerns regarding the intrusion. The company noted that the breach was a result of “a skilled intruder who took steps to cover his tracks.” The hacker created a tool inside PSN’s web application server, paving the way for unauthorized access into databases used to store customer information.

Sony says of 77 million PSN users, approximately 10 million accounts had credit card information on file. Although the credit card data was encrypted, Sony still isn’t ruling out the possibility that the attacker managed to decrypt the data.

Revamped security measures on PSN include the addition of “automated software monitoring and configuration management to help defend against new attacks,” “enhanced levels of data protection and encryption, “enhanced ability to detect software intrusions within the network, unauthorized access and unusual activity patterns,” and “implementation of additional firewalls.”

As previously revealed, Sony is also in the process of moving its entire infrastructure to a new data center, which has been “under construction and development for several months.”

Additionally, to reward loyal customers that have coped with the outage and information theft, Sony is offering region-specific rewards that will include “selected PlayStation entertainment content,” along with a free subscription to PlayStation Plus for 30 days. Existing subscribers will receive an extension of 30 days.
