Sony has issued yet another update regarding the ongoing disconnection of the PlayStation Network, revealing that it is "rebuilding" the whole system.
"We sincerely regret that PlayStation Network and Qriocity services have been suspended, and we are working around the clock to bring them both back online," the official PlayStation blog post reads. "Our efforts to resolve this matter involve re-building our system to further strengthen our network infrastructure. Though this task is time-consuming, we decided it was worth the time necessary to provide the system with additional security."
Based on the info released so far, our experts believe that the PSN security was designed with the assumption that the PlayStation 3 is unhackable and hence the network and its servers trusted all requests that originated from any PlayStation 3. Of course, the PlayStation 3 was hacked and its encryption keys were revealed and it is likely that a hacker has used them to gain unauthorized access to the PlayStation Network and probably to the Marketplace. If this explanation is correct, then it is very reasonable for Sony to shut down the service while it patches the whole communication interface to account for the PlayStation 3 compromise.
