Topic: WARNING: Steam has massive Christmas breech/bugs

[idolminds]

Keep an eye on your email and payment options you have tied to Steam. Details on why this is happening aren't clear yet, but logging in to Steam will show you someone elses account! Your email, paypal email, Steam wallet balance, order history, last 4 digits of your phone number, billing name and address, and possibly other information may be exposed. I just checked the steam account page and I got someone elses account, clicking the account history and license history are showing me the information from 2 OTHER accounts.

This is super fucked and you can't really do anything about it because you can't access your own account details to change them. Valve is going to have a lot of explaining to do.

EDIT: It appears Steam has just gone offline.

Guess it's fixed now.

Valves statement:

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.

I mean, thats one way to describe it. "Some users" is like "everyone".

Also not an apology.

The fuck? That is super bad.

Yeah, my Steam page kept loading in Russian. Tried again an hour later and it was in German, showing a different user's name.

It's fixed now but that was weird.

In typical Valve response time, they finally issued a real statement.

We'd like to follow up with more information regarding Steam's troubled Christmas.

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.

I'm in no way a Valve apologist, but to be fair I'm putting out absolutely zero fires at work in the time between Christmas day and New Years.  At least they're better than me.
