Breaking: Valve Announces Massive Steam Server Intrusion

STEAM LOGO 300x296 Breaking:  Valve Announces Massive Steam Server Intrusion Valve has revealed that hackers have gained access to the Steam database and have pulled countless user names, passwords and other information.  

Earlier this week many noticed that the Steam forums were experiencing issues and were later taken down.  It turns out that the damage incurred by hackers was more widespread than was originally anticipated.

At first it seemed like just the forums were defaced and as such were quickly out of commission but as Valve investigated, it turned out that a database full of user names, passwords and other information was hacked.  As such, the items contained on this database could now be making its way over the usual underground channels.

According to Valve credit card information should still be safe but they are not ruling out the possibility that it too was hacked.

We’ll continue monitoring the situation but until then, below is the full email from Gabe Newell to Steam members.

EDIT:  To avoid confusion, please remember that hashed + salted passwords as stated below are not the actual passwords themselves but rather encrypted versions thereof.  This certainly doesn’t mean they are secure but rather, the people in possession of this information may find it very hard to access the things they need to get into the physical accounts.

Dear Steam Users and Steam Forum Users,

            Our Steam forums were defaced on the evening of Sunday, November 6.  We began investigating and found that the intrusion goes beyond the Steam forums.

We learned that intruders obtained access to a Steam database in addition to the forums.   This database contained information including user names, hashed and salted passwords, game purchases, email addresses, billing addresses and encrypted credit card information. We do not have evidence that encrypted credit card numbers or personally identifying information were taken by the intruders, or that the protection on credit card numbers or passwords was cracked. We are still investigating.

We don’t have evidence of credit card misuse at this time. Nonetheless you should watch your credit card activity and statements closely. 

While we only know of a few forum accounts that have been compromised, all forum users will be required to change their passwords the next time they login. If you have used your Steam forum password on other accounts you should change those passwords as well. 

We do not know of any compromised Steam accounts, so we are not planning to force a change of Steam account passwords (which are separate from forum passwords). However, it wouldn’t be a bad idea to change that as well, especially if it is the same as your Steam forum account password.  

We will reopen the forums as soon as we can. 

I am truly sorry this happened, and I apologize for the inconvenience.

Gabe.

    Hashed and salted password do not equal “passwords”. How about some clarity?

  • Guest

    It’s perfectly clear what it means.

  • Anon

    What’s not clear? They have not stored your password, but a salt+hashed one. It’s the right thing to do.

  • Guest

    The internet is pretty tricky to use these days.

  • Pheloniouspunk

    What, can’t afford a firewall? Idiots. But what do you expect from Steam

  • Gimpism

    lol someone must have installed origin

  • Anonymous

    Hashed and salted passwords can be broken in less then a day with the new GPU based cracking tools.So if they have the hash they have the password change your password now!

  • maher

    Who cares what the intruders did or did not take, ¿will I buy again from a company that is vulnerable to credit-card encrypted data snacth? – I DON´T THINK SO… but Gabe is very, very, very sorry that this happenned, so it´s alright ¬¬´

  • http://www.facebook.com/tink.pez Fisch Pescado

    They should have said that before letting pass 3 days, wtf ! is steam thinking about?, If I lose my games, I want them all of them back! and more! je je

  • Bob

    Ure an idiot…

  • http://www.facebook.com/tink.pez Fisch Pescado

    Also this is why I do not allow any company to save credit data. Because of this.

  • Timonsafari

    Wow if only steam had employed you to solve their security problems, who would have thought this could all have been prevented by a simple firewall.

    I would have thought the exploit would have occurred using an exploit in the forum software, which would have been accessible on port 80, a firewall would only work if they blocked port 80 outright – which means nobody could have accessed the site at all. But hey, you’re the security expert and steam are the idiots. Right.

  • Guest

    So we should stop buying Steam games and go back to pirate them. Those trash don’t deserve our money.

  • Fspam

    Can I have some clarity on how you are a CTO, unless of course, your CTO means: “Cock Toking Orifice”

  • anon

    you are an idiot.
    Salted passwords mean you can crack one password in less than a day. But you have to spend “less than a day” on every single account you want to crack.

    even if it took you 1 minute to crack a password, you would have to spend 1 minute on every single account you want to crack.

    If steam had only 1 million accounts (it has many more than this) you would still take 2 years to crack everyones passwords. (because you would have to spend that 1 minute for every account due to the salt)
    so on average, after 1 year of trying, you have a 50% chance of being being cracked.

    In fact, steam had 25 million accounts back in 2009.
    At my 1 minute estimate (WAAAY overestimating the speed) it would be 47 years before they have cracked everyones password. it will be 4.7 years before they hack 10% of passwords.
    6 months befre even 1% of account passwords are successfully hacked.
    That is assuming it takes 1 minute. (it doesn’t).

    Count all of your friends on steam. if you have 100 friends, chances are 1 of them and only 1 will get hacked.

  • anon

    less of a CTO than you are, he was asking the article not to be retarded.

    A salted hash is MUCH safer than an unsalted hash.

    Basically, they’ll be able to crack your password **if they randomly pick your account to try and hack**.

    It is like giving them a bag full of 7×7 rubic cubes.

    If they pull the rubic cube out that has your password on it, they can solve the cube and get your password. But it doesn’t help them with the next 25 million rubic cubes in the bag, they still have to solve those ones too.

    So individual accounts will be hacked as a result of this, but it isn’t like they have a database full of usernames and passwords.

  • anon

    how does that even make sense?
    everyone here seems to be reacting like its valves fault and not the fault of some idiot hackers

  • Joe

    The main problem here is I bet most users use the same password that their email login uses that they registered with Value. This means you not only need to change your Value login, but also your email account as well otherwise they could be accessed and owned. Salted hashes are easy to crack using oclHashcat but the sheer number of salted hashes does slow it down a hell of a lot.

  • Guest

    That clearly wasn’t my point. My point was that the layperson is going to read this and think their password was stolen. Obviously that’s not the case.

  • PCGamer

    I love how people are still defending Valve and Steam. They effed up people! Total FAIL. Steam is a shoddy client that should be frickin’ OPTIONAL. The SSA is horseshit. The client doesn’t prevent piracy. It doesn’t provide services gamers would miss – if it did the SSA wouldn’t need to exist – it should attract gamers by being a good service, not by being mandatory.

    I hope Valve continues to get rogered again and again, and again, and again… until it becomes an optional client for legit gamers who see it for what it is. A taint to all PC games that ship with the SSA.

  • KJ

    I’m sure that’s incredibly comforting to the one who did get hacked. Further, you are apparently not aware that one can apply computing power to break more than one password at a time. Magic apparently to someone like you, but it’s true. If I could crack one password a day, and steal $100 dollars from that account, in a week I could add a new GPU based cracker. Cracking 2 at a time, add another one in half a week. Then another in 2 days. Ad infinitum. But why do that? We’ve already seen bad actors buying time on EC2 and other cloud platforms specifically to crack passwords. And that cost is falling like a stone.

    So…with all *due* respect, brente isn’t the idiot. You are.

  • KJ

    I don’t get your point. Is there some way that Steam users should react to this differently because it’s “they have everything they need to recover your password” and not “they have your password”? Because if that’s what you’re trying to say, you’re frankly full of crap.

  • Guest

    As a guy who’s built systems like steam, my point is just this.. no system is 100% secure; it’s impossible by definition. These guys did a *great* job building the system, taking reasonable precautions, and communicating appropriately. I’ve been a little disappointed at the media for not clarifying the extent of just how little was actually compromised.

  • dm

    do any of you understand how salts work? without the salt the hackers aren’t getting the passwords. Now if they obtained the salt as well from Valve’s code then rainbow tables can probably crack most of the accounts with minimal effort. Also to clarify to post author, hash+salt != encrypted

  • dm

    valve shares plenty of blame for having weak ass security.

  • KJ

    As a guy who is an information security professional protecting systems on par with the complexity of Steam on a daily basis (for two decades now), and who routinely deals with clients who have significant breaches, allow me to give you my perspective on how “great” a job they did. They got hacked. Clearly for some folks, that’s an “it happens, no system is 100% secure, yada-yada, insert excuses here”. That’s a lousy, lazy way to look at it and I wouldn’t employ an executive that saw it that way, but that’s a different discussion for a different time. Let’s look at what they’ve said and assess the basic blocking and tackling stuff. Apparently they didn’t know about the breach until the hackers defaced web sites. Why not? The user database was compromised, but they don’t know for sure if credit card numbers were stolen. Why not? We routinely deploy off the shelf technology to answer those questions, because when you’ve been breached, those are the only questions that matter, and “reasonable precautions” in my world include being able to answer these questions. Not some time in the future, not “we think” or “maybe”. Indeed, for some of my clients, not being able to answer those question, promptly and completely, is is a company-ending proposition. In my judgement, what has been published points to “minimal precautions”, not “reasonable”, considering the data they were storing.

    So if you want to play “ignore that giant elephant in the room…look at how stupid the journalists are because they got a trivial detail wrong”, then go ahead. If you want to assert “just how little was compromised”, go for it. But in my world, it’s pretty clear that the *only* thing Valve got right is prompt disclosure. Don’t get me wrong, that’s a big deal, and I applaud them for it. But even an cursory survey of previous breaches teaches one that simple username+password disclosures can have broad negative impact, and at a minimum this one includes more personal information than that. Being an apologist and attempting to play down the seriousness of this incident is, at best, irresponsible.

  • KJ

    I was merely responding to Anon’s assertion that compute times somehow mitigate this, or, frankly, any event. For a disturbingly large number of things, the protection afforded by computation complexity has gone from “impossible” to “cost/benefit analysis”. Definitely sloppy of me to muddy the waters and getting off topic. I’m quite well aware of how salts and hashes work (hint: without knowing how the salts are derived, how large they are, which hash algorithm is used, or where the salts are stored, you can’t really make any statement about the best way to crack the passwords. The road to hell is paved with bad decisions here).

  • Foo

    It is not clear (at least to me) that reasonable precautions were not in place. Not knowing the exact details may be a matter of timing. They may still be evaluating log data (it takes time as you know). They also may have the information and not be willing to share because they don’t have a fix yet.

  • Nonofyurbuizness

    Firewalls are a Joke. Ask the CIA and FBI how good it was in protecting them against Anonymous and Lulzsec.

  • Gkaly61

    Steam is such a Joke!
    My account was Hacked & the only way to get support is to sign in.
    Now How am I supposed to sign in if I got hacked.
    Stupid Useless Steam!

  • DD

    Because your Steam support account isn’t the same as your Steam account.

  • DD

    Sure, you also blame the people that had burglars for the fact that they got robbed. Not the burglars. I mean, they should have placed fences, alarms, ap-mines and such to stop the burglars, right.

  • DD

    As a guy who isn’t a security expert I know I would never make comments like yours if I was.

    No were was mentioned that a website got defaced; they never stated that ‘no system is 100% secure’ and the fact that people bring that up doesn’t mean they are fine with what happened; they never played down the incident, they even took quite drastic measure for having just a few forum accounts compromised (as far as we can tell from what they say);

    I’m not going to say it’s all good, but I refuse to put blame of a crime on the victim rather than the perpetrator. They might have been able to do more to prevent stuff like this from happening, but I would be quite surprised if they hadn’t put in all effort they could to stop it before it happened. That includes hiring people like you that are Information Security Experts.

    Maybe he could make up for it by MAKING HALF LIFE 3, DARNIT.
