Nobody has any idea where you're going with this, Crollo.
Perhaps you shouldn't have done it in the first place. Always distrust the system! After all, someone like you knows how it works. Why do you think I run away from online banking?
I'm a very private guy myself, but staying away from online banking? Seems a bit paranoid.
Seeing some of the reactions from this around the web makes me wonder what people actually know about the services they subscribe to. People have their details stored online for so many these days, it's a massive part of how we live. Bank accounts, home loans/personal loans, automatic bill payments, eBay, Amazon, iTunes, Steam, or any other online stores... and any one of those could be compromised by hackers, if they were determined enough, or from one employee mistake.
Sony messed up, sure. They were slow and their security wasn't exactly up to snuff, but the same thing could definitely happen to others. Encryption can be cracked. Living in fear of identity theft or fraud isn't something I want to do, it's a threat you face just from using these services.
Just keep a close eye on your shit, and report anything suspicious. Shit just happens sometimes.
