This is from the Sony blog An Important Message From Sony’s Chief Information Security Officer – PlayStation Blog
ohno... here we go again! Well i said it not just the other day with PSN being down so much and all this Maintenace something fishy was going on and sure enough it seems it was... Good Grief, Charlie Brown!
As I recall, it's not about luck. They angered some people with some shady moves and then it sorta snowballed from there. This is probably just another knock-on effect from that. Sony's one of the largest corporations in the world. Not to have its security maxed out, rigorously tested, and constantly updated was suicide, not bad luck. I will say I'm glad to hear that it sounds like discovery, intervention, and reporting were much more prompt this time. It may be, though, that that's mostly because these attackers came in the front door and apparently weren't able to do anything that Sony felt was embarrassing. If they really did get the logins somewhere else, then it's disturbing to hear that so many of them worked on PSN. Use different passwords on different sites, people! If you get all clever and make an eleventy-seven-letter password, filled with special characters and numbers and sanskrit words, but then you go and use it on every site you visit, it only takes an intrusion on one site to compromise your accounts on all sites...
Good thing Sony announce it early VS waiting a week later to the masses on what happened with the network service. Its crazy how fast we are with online breach VS online security. I hope this doesn't happen again or at least for the next couple of months. I am begin to worry and loose faith with Sony if their online service and user's account keep getting breach.
