Steam security issue revealed personal info to other users on XMas Day (fixed)

Well the 10 cent in my steam wallet is gone. Not that I would be sad over that, but well means someone definitely saw the info I had there.

Nothing odd in order history or email through.

Check your purchase history.
You should be able to see if anyone has made any purchases.

EDIT: Derp. Missed that you mentioned your order history. Maybe it's just the servers still being janky, then.
 
But that's not really the case from what I understand. It's just name, address, phone number, last four digits of CC, right? No passwords or usernames? You don't need to be scared about your games.

People have been reporting that their PayPal accounts have been emptied and charges made to their payment method on Steam, being worried is entirely natural when not a lot of information is out there except for the fact that something is messed up.
 
Yeah, I'm not starting Steam until an official response.

That bolded stuff is way more fucking important than access to the games.

All of that you can find in a phonebook though. The worst part is partial CC information, which while not as bad as an actual hack is still easy to use to get access to accounts elsewhere.

Maybe companies will stop taking partial CC info as identifying information in the future, but lol
 
I don't understand people who are immediately logging on right now when we've had no official statement about what happened.
 
Able to open Steam and log back in.
Nothing missing from my wallet and no purchases/activity on my account besides recent selling of trading cards to idiots, so lucky escape it seems.
 
For folks with Paypal linked to Valve, go login to Paypal and unauthorized Steam from the list of approved merchants. Should at least keep that portion safe. Glad I took my CC's down years ago. Will only do pre-paid cards from now on.

Also, will this be the kick in the nuts for Valve to improve their terrible customer service department? They are a multi-billion revenue business and their CS operates like it's a volunteer position. Time to step up to Amazon levels, damn it Valve.
 
What some are speculating is that due to some misconfiguration, pages that shouldn't be cached are ending up being cached anyway. I don't think anyone's saying that's how it should work, just trying to figure out what makes sense given what we're seeing.
Having configured plenty of caching and CDN services (not just Akamai and Varnish, but xCache, WP Total Cache, Litespeed, and CloudFlare) I do not think it's a "misconfoguration". You don't go into a cache software's .config or what have you and go "oops I just accidentally allowed everyone to see other people's info".

People who are being told it's caching are probably being misled. I could very well be wrong but this isn't what happens when a caching service goes down or gets "Misconfigured".

At best if it IS caching, then it means Steam has been caching unencrypted customer information at remote servers and/or at their local server, which is a massive no-no for PCI compliance and CC processing standards.
 
You don't understand how caching works, do you? I used to install various caching options (including Akamai CDN which is external as well as Varnish which is a software caching service installed on the server) all the time.

The behavior seen today is not something that happens because of caching.

Caching for dynamic user related content is a no go per se. If someone pushed a new version of the account page with caching enabled it could cause this problem. It would also explain why people saw the same subset of users. Those poor guys were the first to open the new account page and for every respective server they hit they became the cached page.
 
My steam is always logged in. Am I fucked

Probably no more fucked than anyone else. No one is yet sure who was able to access what other people's info, or if there was any rhyme or reason to it. So it essentially comes down to a) did anyone manage to get your page in the lottery during the hour the site was up, and b) did they do anything with your account. I don't think being logged in or not affected anything; if it was indeed a cache issue (jury's still out), it would depend on whether you accessed your own account details recently, and what the definition of "recently" is to Steam's server cache.
 
I can confirm that nothing got charged on my account, and that no other accounts have been created with my information. I will keep an eye out to make sure no accounts are created.

I highly recommend that anyone using Paypal for your Steam purchases to use the Paypal security key. It uses two factor authentication so not only do you have to log in using your password but also a key you receive via text message.
 
Got my account info up now. All anyone could see was the last two letters of my Visa card, country, & one of my email addresses... While not ideal, it could've been a lot worse.

Nothing unusual in the purchase history, and no difference in account funds, but I've deleted my CC info.
 
I don't understand people who are immediately logging on right now when we've had no official statement about what happened.

Even if you still need to put the security number, I really want to go in and take my credit card info and other important information out now.

But im also scared to do it now because we dont really know if this could be still a problem.
Waiting to see what other people are doing.

But then, its valve, maybe we are going to wait some days before an offciail response becuase they have monkeys working in some departments there.
 
What's up with people so invested in running damage control on Valve's behalf
I feel like there's a joke to be made here about Valve's tendency to promote user-created content, but I don't have the wit to come up with it.

Anyway, is it safe to log back on or no? I was hoping to play some games, not really planning to buy anything right now.
 
During login I got "Verifying login credentials" or something like that, gets stuck then gives a connection error. I've restarted the client and now everything seems normal though.

Might be an idiot for doing this but I suppose Valve fixed the leak when they rebooted the entire thing.

Hopefully.
 
So if I have a credit card linked to my account, do I need to cancel my card? I haven't been logged in since Tuesday and haven't logged in today, am I okay? Maybe I should wait for the whole thing to calm down.
 
I barely use Steam and the last time I logged in is months ago. But I still checked my mails and the latest one was from the Steam Store.


A game on my wishlist is on sale.

I kind of hope this doesn't just blow over for Valve. Can't have them thinking they can just keep coasting on their good name.
 
Well between playing computer games and protecting myself from identity theft I know which one I'd pick.

Again, I predict that your personal details has been breached at least twice before today.

I kind of hope this doesn't just blow over for Valve. Can't have them thinking they can just keep coasting on their good name.

It's looking like it's more or less all over after three hours, and therefore it'll be completely forgotten about before the new year.
 
I can confirm that nothing got charged on my account, and that no other accounts have been created with my information. I will keep an eye out to make sure no accounts are created.

I highly recommend that anyone using Paypal for your Steam purchases to use the Paypal security key. It uses two factor authentication so not only do you have to log in using your password but also a key you receive via text message.

That seems rather excessive considering your Paypal password is not stored in steam at anytime. The only thing exposed related to paypal is your paypal email adress and your related personal info.
