True I may feel compelled to be angry at the hackers, but nonetheless, I'd be even angrier at Sony for such poor security. They kept the info in plain text.... this speaks volumes on how well they cared for their customer information.
It's unfortunately not just Sony that stores passwords in plain text. I'm a Sirius Radio subscriber and called a couple years ago to change something on my account. After the guy on the other end was done helping me, he said "Just a reminder, you can access your account online. Your username is ____ and your password is ____."
I was completely dumbfounded. Not only does Sirius store them in plain text, they make it available to their outsourced call center reps in Bum**** Egypt. Who knows what else they can see, my credit card info? Needless to say, I quickly went online and changed my password to one I don't use anywhere else.
And then there are other various websites from major companies where when you go through the "Forgot password" process, it will show you your current password rather than letting you reset it. I can't believe in this day and age, companies aren't using some sort of one way hash. Even MD5, with all of it's flaws, would be a huge improvement.
