The same group became infamous for hittin PBS earlier this week has just announced that they've now hit Sony with a SQL injection which allowed them full access to various Sony databases. LulzSec statement:

Our goal here is not to come across as master hackers, hence what we're about to reveal: SonyPictures.com was owned by a very simple SQL injection, one of the most primitive and common vulnerabilities, as we should all know by now. From a single injection, we accessed EVERYTHING. Why do you put such faith in a company that allows itself to become open to these simple attacks? What's worse is that every bit of data we took wasn't encrypted. Sony stored over 1,000,000 passwords of its customers in plaintext, which means it's just a matter of taking it. This is disgraceful and insecure: they were asking for it. Rob Beschizza, writing for BoingBoing: Sony traditionally is run as a set of 'silos', independent departments, divisions and joint ventures that have much autonomy from one another. This might be why there are so many different attacks: there is always another Sony silo which runs its own web infrastructure, where hundreds of dollars worth of web development can go down the drain, just like that. Ouch. As I said last week on Twitter, friends don't let friends create user accounts on Sony networks.
