Steve Watts posted a new article, Timeline of Sony data theft.
A detailed timeline of events in the PlayStation Network and Sony Online Entertainment data thefts.
12,700 credit cards 'compromised'? wow..... so much for them being encrypted.
they said the PSN CCs were encrypted, not the SOE ones. different events
why would you encrypt one set of credit card numbers but not another? Honestly at this point i dont trust what sony announces, and have less trust for their services.
Because there are many teams working there, and apparently not all of them know what they should be doing.
Right, which is why i am saying that i dont trust the company anymore.
To give your credit card information out...especially online...requires alot of trust. Trust that you wont get ripped off and the company provides the service you purchased, but also trust that they are storing your information appropriately. In this area, sony is clearly lacking.
Its unrealistic to expect a system to be completely unhackable, but a certain amount of due diligence can be expected, and demanded, of a company. To not even encrypt the data, even if it is old, is pretty bad.
So....in my opinion sony has proven themselves to be untrustworth and that is something that is very hard to come back from.
someone in the UK managed to spend over 2000 pounds on my CC last week before I noticed and had to cancel my card, and I live in Canada! bastards!
