Malware Distributed Through Twitch Chat Is Hijacking Steam Accounts 53

Posted by samzenpus from the protect-ya-neck dept.
An anonymous reader writes If you use Twitch don't click on any suspicious links in the video streaming platform's chat feature. Twitch Support's official Twitter account issued a security warning telling users not to click the "csgoprize" link in chat. According to f-secure, the link leads to a Java program that asks for your name and email. If you provide the info it will install a file on your computer that's able to take out any money you have in your Steam wallet, as well as sell or trade items in your inventory. "This malware, which we call Eskimo, is able to wipe your Steam wallet, armory, and inventory dry," says F-Secure. "It even dumps your items for a discount in the Steam Community Market. Previous variants were selling items with a 12 percent discount, but a recent sample showed that they changed it to 35 percent discount. Perhaps to be able to sell the items faster."

    That is why I do not understand why there _are_ people who are simply void of any common sense

      Except in this case it does not. It asks for your name and email. Nowhere does it say anything about a password.

      • Yes but isn't there enough history about the internet that says "Don't click links from people you don't trust?". Not that pretty much anyone hasn't broken that rule at one time or the other.

      No where do they say they are asking for the steam account info. Fake raffle wants a username/email & password to sign up, then it installs a program that access your steam stuff. most people on their home computer either have steam running all the time and are logged in, or auto log in.

      I do don't do twitch.tv and I don't bother signing up for online raffles or anything claiming i will win something, because that is stupid.

        Why would it be a raffle or some other semi-sleazy subject?

        Asking for a username and email is standard practice for pretty much any kind of website signup.

        If I were into gaming enough to watch somebody else play a specific game on Twitch and somebody posted a link to a legit-looking site claiming to provide me a valuable service for that specific game, I might well be fooled.

    • I wouldn't say so much as "devoid of common sense", but rather "trained to ignore warnings"

      Microsoft is probably the biggest offender here. In trying to provide better security to the end user, they end up bombarding them with warnings, which mean nothing bad 99% of the time (e.g. IE ssl warnings, UAC warnings, etc). Users start to think nothing of these, so they just start to ignore them.

      "Basic AV" is useless against any determined attacker. Yes, in a few weeks, maybe even in a few days if the AV is really "good", the AV would find the trojan horse that you installed, but the one you installed disabled all defenses and the one you'd get in a few weeks or days is different enough that your AV won't do anything then. People with common sense don't need AV and people without common sense are not helped by AV. I see the remnants of the infection vector all the time: Installers, usually of some

      Basic AV = not automatically executing stuff.

      If you mean something like real-time protection from common AV packages, then those are technically reactive to threats and don't detect new things within the past ~24 hours or so.

      That is not how Sandboxie works by default. By default, Sandboxie prevents changes to files on the system itself, but allows sandboxed items to read everything. So things running inside the sandbox, including this malware, would be able to do everything the summary describes unhindered. And if you have the sandbox set to delete all its contents on a program closure (like your browser), you would not even know, or even have a trace, of what happened.

  • Not that I don't just assume its Windows, as usual, but, it would have been nice to specify that this is only happening to people unfortunate enough to be running Windows. If it was happening to Mac users also, I would bet they'd mention that.
    Of course, I'm pretty sure I'm safe on my linux platform.

    I've been using Steam for a while, but I don't know how to look at either of these things. I guess I'll have to poke around when I get home.

    I just buy and play games. As far as I'm concerned it's a game launcher.

    I remember a lawsuit a while back about being able to resell games, but didn't realize there was a "marketplace" to do that within steam. I knew there were coupons or promo codes, but didn't realize there was a wallet.
