Sony's response to this has been golden.
"Hackers": Look at this guys, no security, unsalted hash, lolololol.
Sony: Shut. It. Down.
Customers: ?
Sony: ...
Customers: Must be maintenance. Right?
Sony: ...
"Hackers": Look at all this info we stole! Hurr, no encryption on anything, plain text tells me where your girlfriend lives.
Sony: ...
Customers: WTF!? Sony?
Sony: ...
Media: Sony hacked, personal info may include CC numbers in addition to most of your sensitive personal info!
Sony: ...
Customers: Is this true OMG!!
Sony: (nearly a week later) Evil haxx0rz bypassed our non-security, we can assure you only unimportant info was stolen, like your name and address etc. No CC stolen!
Customers: ... eh ... alright, when is PSN coming back up?
Sony: ....
Media: People reporting credit card fraud, stolen IDs, mysterious bullshit ... is it Sony?
Customers: MY DATAS
Sony: ....
"Hackers": <trollface.jpg>
Sony: Alright, MAYBE a few OLD and unimportant CC numbers and debit card numbers got snatched, no big deal though ... oh, and this is for SOE stuff, who knows how long we've known about this! Thanks for your support! We'll be up soon, with free 30 day trials of shit you don't want anyway! <wink.jpg>
Media: LOL LOOK AT THIS SHIT.
Customers: FFFFFFFUUUUUUUUUUUU
Sony: (takes down SOE websites, online games, replaces with "We will catch evil criminals and we are not liable for your losses, bitches.")
That about sums it up, I think. Point of my dumb little strawman skit: Sony reacted late in the eyes of the public, preventing people from taking informed action immediately, and Sony hasn't been all that clear on what they're doing other than chasing bad guys (haha, sure) and securing their stuff.
I've already gotten new credit and debit card numbers, my credit union was very understanding -- even had a special team to handle Sony fraud issues.
TL;DR: Sony is a terrible company run by terrible people. The lack of concern and security for our personal information is insulting.
