Why it Took Sony Seven Days to Tell the World

Valued PlayStation Network/Qriocity Customer:
We have discovered that between April 17 and April 19, 2011, certain PlayStation Network and Qriocity service user account information was compromised in connection with an illegal and unauthorized intrusion into our network.

"There's a difference in timing between when we identified there was an intrusion and when we learned of consumers' data being compromised. We learned there was an intrusion 19th April and subsequently shut the services down. We then brought in outside experts to help us learn how the intrusion occurred and to conduct an investigation to determine the nature and scope of the incident.
It was necessary to conduct several days of forensic analysis, and it took our experts until yesterday to understand the scope of the breach. We then shared that information with our consumers and announced it publicly yesterday evening."
