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

man, I was all like

I wonder if we'll get a satisfying explanation for this. I've been out of IT for four years now, so maybe I'm just out of touch, but it's strange to think about unencrypted customer data just hanging out someplace where anon/public access is sufficient. & actually that doesn't even sound like the kind of indexing/whatever problem that would return the random results we've all seen. So that's two questions, I guess.

Just doesn't really follow for me, not that they would disclose their own architectural details... just sounds weird.

Anyway, this really has shaken my confidence. I hope they will communicate effectively with regard to both root cause and countermeasures. I've been going crazy with PC games ever since I got this laptop, and am really enjoying the platform.

This is the most likely explanation I have seen yet:

reddit said:
It's a problem with their caching-server (varnish), caching pages that should not be cached (such as Account-Details, Cart, etc.). It invalidates after some time and is re-cached when the next user visits the page with their profile. You are not actually logged in (as in, you take over the session of the user), you just see pages rendered for others than yourself. This is why different parts of steam appear as different users.

Which page you see is probably dependent on the edge node (first server you connect to) closest to you, hence why different users see different profiles.

My guess to how this could've happened is that an untested configuration got activated when steam went down earlier, e.g. due to an auto-conf service (puppet, chef) pulling an untested config or some of their live servers being replaced by staging / development servers. It's also possible that they were under heavy load and the engineer on duty reconfigured all their edge nodes to cache more aggressively.

Let's hope they fix this fast, because this is a major data leak. I can see private E-Mail and account names. Let's hope their cache server is not delivering internal pages.

If you purposefully misuse your information they won't credit you back. If it is compromised they will.

I don't know why people have to be so defensive about credit card "theft" because it never hurts the card owner unless you admit to doing the purchase or something.
Never hurts them? So you're fine with that info being in the hands of total strangers? People can use that info to sign up for accounts on websites etc. What is wrong with the people who don't see an issue with this?
 
All of mine say steampowered.
That's just strange. Why would valve register their domain via a 3rd party that hides their ownership? Maybe they bought the domain from a some private owner some time ago and just kept it there. Anyway, its weird.

To prevent domain registration-related leaks, I would presume.
 
Shit, just got home and see this thread. Try to login to my Steam account and keeps telling me password and name error. When I press cant login, it said it cant connect to the server. Is this normal or am I screwed? I got like $23 dollars in credits.

The servers are still wonky, it doesn't mean your account has been stolen.

Now now what have i told you about using the naughty word "misleading"?
Talking from your ass isn't a nice nor a clean thing to do you know.

Sorry, I meant to say "lying."
 
My card was removed from Steam. Am I still okay to go PayPal?

Paypal offers an extra layer of security than having a CC linked directly to your steam account....so yes

I don't link my CC directly to any online service for this very reason, although it is currently linked to my paypal account as a backup payment.
 
RE: Unauthorized purchases

My guess is, provided the unauthorized purchases reported are true, that they fall into two categories:
1) User A was logged into User B's account, went to buy something without realizing he was logged into User B's account
2) User A was logged into User B's account, decided to troll by spending User B's money.

It's hard to imagine that anyone was benefiting from this the way they were with the FIFA points stuff, because you couldn't play the games or use the items you "bought" from another person's account.
What about gifts? Buy and send it.

This. Even with "my paypal account" in the dropdown, it still opens a new Steam client browser window to authorize the paypal payment - it has you log into paypal.

You should be using this instead of the credit card method that stores your CVV. Also, remember that revoking your card and adding it again sometimes causes issues where you need to wait on Steam - people learned this the hard way by adding new cards immediately prior to sales in the past, they were unable to purchase things for a day or two, IIRC.

That could be one possible abuse, but it would leave a paper trail to get your subsequent account banned and I can't imagine it'd be for a resale scam since the rollback is likely to occur before the resale. Could be possible though.

No, they can't use that info for anything of any consequence. What, they sign up for an eharmony account or something? Lol.

A compromised ssn is a bigger deal but there are free and fairly painless ways of protecting that as well.

There are laws about how credit and credit card companies must handle these things that protect the consumer. Breaking those laws carries harsh penalties for the credit card issuer.
 
Is the thing about not deleting your cc information true? What to do? Should I delete it or just leave it alone like Steam DB said?

The only reason they said that, is because accessing your account page (to delete your cc) would add your cached account page to the 'pool'

It appears that loophole has been fixed, so you're probably fine to do it now
 
Yikes, I'm pretty sure I don't have my CC or paypal saved on steam, but I'd like to be sure... is there a safe way to check or are still not visiting steam pages?


Oh well alright then :P
 
got on safely and removed my shit. only had a dollar in the wallet, though if this happened tomorrow it wouldve been 120 due to christmas steam gift cards

bullet dodged
 
I contacted my credit card company and told them what happen. They shut down my current card so that nobody can use it and sent me a new one.

Might be overkill but i'm not taking any chances.
 
My wishlist on the Store tab is gone, but can still access it from my Games list.

Other than that, haven't seen any changes. My comp stayed logged in from yesterday, not missing any Steam credit.
 
Still can't log on. Been trying to remove payments and personal info for hours now.

As this is a caching issue, it's actually not a good idea to attempt to remove any information from Steam right now. By accessing (viewing) the information, you potentially air it to others. That said, the problem seems to have been fixed, but we have no confirmation of that yet.

My suggestion to everyone is to just stay out of your Steam's account management for now, wait for a statement from them, and then--regardless of what Valve says or doesn't say--check your bank/credit statements regularly for suspicious activity.
