“A source with close connections to Sony Computer Entertainment Europe reports that the attack to the PlayStation Network may be a bit deeper than originally reported by Sony. According to the source, who wishes to remain anonymous, the PSN sustained a LOIC attack (which created a denial-of-service attack) that damaged the server. There was also a concentrated attack on the PlayStation servers holding account information. In addition, “Admin Dev accounts were breached.”
As a result, “Sony then shut down the PSN and [is] currently in the process of restoring backups to new servers with new admin dev accounts.” The SCEE source said Japanese servers may be restored tomorrow while the U.S. and E.U. servers will likely be operational the following day. ”
