Steam hit by security breach - store taken offline

Not the sort of thing I wanted to wake up to this morning. Doubly so since it's in the middle of the winter sale.

Not an official tweet, but ... Yay for apparently not hacked, but still bad from a security POV.

Apparently it's not a security breach, just one hell of cache error.

I think my favourite part of this is console users having a bit of a laugh about the situation, did they forget what happened last year?

Worth it to note, just stay clear of anything Steam related until the all clear, including mobile app and the website. Especially don't try removing your payment details using Steam, instead contact your bank or use the PayPal website to remove details.

You are likely viewing the details of someone else's account. Just stop using the Steam website for the time being.

I would've thought that the case, so logged out of steam.

Then on trying to log back in it required an authenticator. For my account.

I sent in a ticket but with Steam down (and the holiday period) I doubt it'll be seen for a while.

It's fine now, just a bad cache configuration error. It's possible someone perused your purchase history, saw your address and possibly last 4 digits of phone number/credit card.

Check your purchase history if you're worried but there shouldn't be any issues beyond a bit of personal details stuff leaking. Probably not even that if you weren't running Steam at the time anyway. It's not great for Valve's reputation but individuals don't really need to be worried.

Some frequently asked questions:
  • No, Steam is not hacked
  • Creditcard info and phone numbers are, as required by law, censored and not visible to users
Valve Software wrote:Steam is back up and running without any known issues. As a result of a configuration change earlier today, a caching issue allowed some users to randomly see pages generated for other users for a period of less than an hour. This issue has since been resolved. We believe no unauthorized actions were allowed on accounts beyond the viewing of cached page information and no additional action is required by users.
25 Dec 2015, 23:16 GMT: The issue now appears to have been resolved, and the Steam Store is back online.

I can't see my inventory currently, is this related?
Keeps telling me "Inventory is not currently available"

Edit: Restart of Steam fixed it up

What happened

On December 25th, a configuration error resulted in some users seeing Steam Store pages generated for other users. Between 11:50 PST and 13:20 PST store page requests for about 34k users, which contained sensitive personal information, may have been returned and seen by other users.

The content of these requests varied by page, but some pages included a Steam user’s billing address, the last four digits of their Steam Guard phone number, their purchase history, the last two digits of their credit card number, and/or their email address. These cached requests did not include full credit card numbers, user passwords, or enough data to allow logging in as or completing a transaction as another user.

If you did not browse a Steam Store page with your personal information (such as your account page or a checkout page) in this time frame, that information could not have been shown to another user.

Valve is currently working with our web caching partner to identify users whose information was served to other users, and will be contacting those affected once they have been identified. As no unauthorized actions were allowed on accounts beyond the viewing of cached page information, no additional action is required by users.

How it happened

Early Christmas morning (Pacific Standard Time), the Steam Store was the target of a DoS attack which prevented the serving of store pages to users. Attacks against the Steam Store, and Steam in general, are a regular occurrence that Valve handles both directly and with the help of partner companies, and typically do not impact Steam users. During the Christmas attack, traffic to the Steam store increased 2000% over the average traffic during the Steam Sale.

In response to this specific attack, caching rules managed by a Steam web caching partner were deployed in order to both minimize the impact on Steam Store servers and continue to route legitimate user traffic. During the second wave of this attack, a second caching configuration was deployed that incorrectly cached web traffic for authenticated users. This configuration error resulted in some users seeing Steam Store responses which were generated for other users. Incorrect Store responses varied from users seeing the front page of the Store displayed in the wrong language, to seeing the account page of another user.

Once this error was identified, the Steam Store was shut down and a new caching configuration was deployed. The Steam Store remained down until we had reviewed all caching configurations, and we received confirmation that the latest configurations had been deployed to all partner servers and that all cached data on edge servers had been purged.

We will continue to work with our web caching partner to identify affected users and to improve the process used to set caching rules going forward. We apologize to everyone whose personal information was exposed by this error, and for interruption of Steam Store service.

Been checking out the sales on a daily basis and purchasing, downloading/installing and never seen any of the issues mentioned. Only thing that went to shite was the search function that I could see. But that's been fine for the last couple of days as well.

As Valve explains, the issue was only present between 5:50AM and 7:20AM AEST on the 26th. If you weren't browsing the site at that time, you were/are not affected.
