Amazing that even after their serious PS3 breaches, they still have such major holes.
As an aside, my group in 1989 got Sony on the Internet by registering sony.com! This is when the Internet was not yet commercial. We ran it for a few years, paying something like $20,000 to Stanford for our Internet connection. Then a few years later rest of Sony discovered the Internet and this IT guy came begging to get control of the domain and the computers serving it. He knew so little about it but we let it go and that was that as they say.
We will unfortunately see more of these. Worse similar events will occur without our knowledge! IT Security if an afterthought for most people and surprisingly most companies. They often think security in terms of products..: Buy one or more piece of software or hardware and you're done with security, rather than as a constant and permanent process. Once a company is on the Internet it becomes the potential victim of millions of people most of them clueless but a good percentage I would venture 2%, knowledgeable and sophisticated. If it is worth their while then you, better be careful. Sony is learning this the hard way , others will or may have already followed....
I remember in 1980s we had sold computers to the air force and we couldn't duplicate an issue they were having initially. The "brass" came to visit us complaining. This was for the B2 Bomber project which at the time while the name quite public, was still a highly secretive project. So I go and meet with the technical crew and they invite me to come on location to diagnose the problem. Surprised that they would let someone like me just show up there with no clearance and such. So I asked if they were not concerned. They said no because there were two conditions to how they ran it.
1. NO physical connection to the outside world. No network connection and no ability to move bits back and forth.
2. And this was the kicker: "two armed guards will escort you everywhere you go!"
The line that was used then was that physical security was mandatory in any good secure system. The fact that Sony folks put all the bits online shows that they don't appreciate this lesson.
* Got all his best albums (LPs), and a dozen or so CDs.
Plus few DVDs (including 'History') and his 'This Is It' latest Blu-ray (just awesome)!
By the way, Sony has been going down for the last year or more in their Blu-ray packaging (many of them); very cheaply done, and the cheapest quality paper, and plastic too.
Just an example on Blu-ray: 'Das Boot'. Awful packaging, worth less than a nickel!
