To me it sounds like lawyer-speak for "We don't think they do but we're covering our arses"

Why can't it just mean "we don't have a clue whether they do or not?"

Because then there wouldn't be a conspiracy theory, of course!

(I'm not taking any chances, either way)

This is a good time to purchase a password-vault app - AND USE IT!

Okay, I see KeePass and Password Gorilla recommended here in the other replies. I use KeePass actually, and I've seen PGorilla. But I'd like something that is integrated with the iPhone - and works with Linux and Windows too. There's an app called Strip that looks pretty good. I'm listening to other suggestions.

I just email and normal encryption methods. It's the simplest thing for me.

Salt is bad for you: http://news.ycombinator.com/item?id=1209254

Salted hashes are better than unsalted hashes.

Against a GPU that can calculate five million hashes per second your salt isn't worth the paper it's printed on.

I wonder how many times a company can install trojans on your computer, destroy your OS's security, secretly watch all your actions, then proceed to not properly protect your data when you voluntarily give it to them...before going out of business. Sony's size and momentum must be pretty crazy. Or maybe it's our society. I just can't imagine a small record store in the 1960s, after being caught spying through the bed…

Don't read this as a defense of the company, but there hasn't really been a single, monolithic Sony for decades. Sony Music Entertainment, perpetrators of 2005's rootkit debacle, is pretty far removed from Sony Computer Entertainment, the division responsible for Playstation. Sony Electronics, makers of TVs, home theater systems, and Walkmans, is another silo, as is Sony Pictures. Of course, every act of incompetence…

Not to mention that Sony BMG was a 50% joint venture with Bertelsmann and I don't recall many people boycotting magazines or books at the time.

Notice how they never apologize? The closest thing to apology, but it's not an apology, is: > "We thank you for your patience as we complete our investigation of this incident, and we regret any inconvenience." Sony apologizes only to Chuck Norris.

That is very standard legal. If they did so, the impending class action would already be over. I wouldn't be surprised if that blog post cost them well into 6 figures for legal fees. And that it took the full week to draft and approve--it is probably the reason this announcement took so long to emerge.

True. Big incidents like this require for companies, in this case Sony, to carefully choose their words. They are obliged to inform their customers.

Wait, "Password" was stolen? WTF they store unencrypted passwords?!?!?!!?! I sure hope they meant password hashes otherwise upset many people should be.

Even if hashes are stolen, you should consider the original password stolen as well, because it's only a matter of time and effort to brute force the original password from the hash. Even if you use a really good password with a really good hash (like bcrypt), it still doesn't mean that they can't find the password, just that it will take more time to do so.

A really good password with a really good hash takes more time for values of time exceeding far exceeding any human's lifespan.

Assuming a 10-character random alphanumeric, that'd be 62¹⁰ possibilities (26 uppercase + 26 lowercase + 10 numbers = 62). Even given an insanely fast brcypt of 1µs, that's over thirteen thousand years to get to a 50% chance.

Now, if your hash is a bad one, say MD5, then you're in trouble. GPUs could brute force that ten-character password within a year.

Salted hashes are better than unsalted hashes.

If you insist on using fast hashes, a double salt double hash sandwich is what I use.

		sha1($Salt . sha1($Food . $Salt))
Something like this should be used at a minimum - maybe even toss some herbs and spices in there and hash it a couple more times for good measure. And I know this from my own experience in finding security holes. wink

That wouldn't work over SSL, as there is no plain text in the HTTP Verb. And I recall a "paper" coming up some months ago that was mentioning the protocols the PS3 goes through, which does confirm that the data is transmitted over SSL.[0] [0] http://arstechnica.com/gaming/news/2011/02/report-psn-hacked...

The SSL gets decrypted inside the web server process memory, at the latest. Sometimes it's stripped off by an SSL offload accelerator device before even entering the web server. The numbers probably also cross the wire in plain text between the web server and the database too.

Anecdotal, but I'd say stripping SSL at the border is much more common that leaving it intact to the node.

This seems like a really big argument for never allowing your data to be stored by a 3rd party. Does anyone see any reason why these companies should do anything other than store the data locally on your system, encrypted/obfuscated, and then only ever send once, via encrypted connection, and then immediately delete the info remotely? I mean, if someone breaks in to my house and steals my PS3, they already have acces…

While I think I agree with you, but rule #1 when doing client-server development is: Never, ever, trust the client.

And, ironically, something which I think Sony forgot here. :)
