Yahoo Advertising Serves Up Malware For Thousands 184

wjcofkc writes "Thousands of users have been affected by malicious advertisements served by ads.yahoo.com. The attack, which lasted several days, exploited vulnerabilities in Java and installed malware. The Netherlands based Fox-IT estimates that the infection rate was at about 27,000 infections per hour. In response to the breach in security, Yahoo issued the following statement, 'At Yahoo, we take the safety and privacy of our users seriously. We recently identified an ad designed to spread malware to some of our users. We immediately removed it and will continue to monitor and block any ads being used for this activity.' While the source of the attack remains unknown, Fox-IT says it appears to be 'financially motivated.' The Washington Post cites this incident as a reminder that Java has become an Internet security menace."

    The Washington Post cites this incident as a reminder that Java has become an Internet security menace.

    As far as I've been concerned, Java and Javascript have both always been security menaces.

    Letting web-sites and advertisers execute code has been a recipe for problems for a long time, which is why many of us here likely already block it.

    This is just another example of why we can't trust the companies doing the advertising, because they're part of the problem -- if Yahoo is serving malware, Yahoo can't be trusted.

              With all due respect, his post was a lot more insightful than yours. You don't appear to know what you're talking about.

              First of all, "deployed the same way" as in "deployed using an HTML <object> or <applet> element that instructs the browser to download and execute the code". The Microsoft Visual C++ redistributable runtime does not include any such mechanism for deploying C++ code. For that matter, not all Java runtime installations do either.

              Second, just what do you think ActiveX is programmed in? Hint: it's not its own language. It's a packaging system for COM classes, which are almost without exclusion written in C++, and it *is* possible to deploy and run it in the browser in much the same way as Java applets (object tags). Unlike Java, they run with basically no sandbox but instead require considerable amounts of confirmation before they download. The idea is that they are powerful but unsafe, so only use the ones that you trust. Unfortunately, a number of pre-installed ActiveX controls on Windows have security vulnerabilities in them, so an attacker who finds a way to exploit one of those pre-installed ones doesn't need to get the user to download anything. Hence the way that modern versions of IE require the user to confirm before running an ActiveX control that they've not previously indicated that they trust (and also give you an ability to disable ActiveX completely or only enable it on a site-by-site basis).

              I don't care for the Java installer any more than you do, but the security issues with Java applets have literally nothing to do with the language. The only way you could say Java itself is at fault is if you were to argue that Java shouldn't have any OS bindings at all (that is, no ability to access the file system, no ability to create processes, no ability to open network sockets, etc.). This is essentially the situation with JavaScript, of course; while the Java applet sandbox tries to *restrict* the use of functionality like I just mentioned, the JavaScript runtime (as found in browsers) simply lacks APIs to access such risky features. Even there, though, that's not a characteristic of the JavaScript *language* but merely of the sandboxed runtime used to execute JS in the browser. Other uses of JS, ranging from Windows Script Host to Node.JS, are perfectly capable of doing such things.

          • ActiveX made no attempt at sandboxing. Java does, but the problem is a monoculture. There are four JavaScript implementations in widespread use, and so if you want to exploit a vulnerability in JavaScript you won't get more than one browser. Exploitable JavaScript bugs tend to be partly due to the DOM and other components of the browser. In Java, there is one widely deployed JVM, including all of the supporting libraries. If you find a bug in it, then you can exploit anyone who still has the Java plugi

      Indeed, the ad ops teams that "screen" these ads cant read code, and even if they could, the code in the ad tags is "minified" JS and they just can't logistically read each ad tag because of the sheen number of ads they need to run each day/week.

      If Java didn't exist, nor Flash or Acrobat, these criminals would STILL be using the ad networks to compromise the browser itself. That's not to say the plugin model is a good one, but it's important to focus on the real problem.

      This is true for all websites too. I suspect the WashPo uses the same ad ops standards Yahoo does, same as Slashdot, same as everyone. It's ad networks running arbitrary, 3rd-party, unknown code on users machines that's really fucking dangerous.

      Indeed. I block 100% of ads my tools can identify, I consider this a routine security precaution, and I make no exceptions.

In Chromium, this is easily enabled in Settings -> Show advanced settings -> under "Privacy", Content Settings -> choose "Click to play" under Plug-ins.

        Java (and Flash likewise) has never been safe, and it's a shame that click to play is not the default. Additionally, animated ads are often Flash or Java-based, so this also kills distracting movies

    The moment that Yahoo allowed advertisers to use java they knew that minimally those ads would be used to annoy the crap out of the users. If your ad is a static picture with a clickable link then you don't need Java. What you need java for is to start prying into the user's business. Animations, sound, geolocations, saving data to the user's machine. So any "legitimate" ad using Java is halfway to being malware already. Plus why use Java instead of Flash? Generally ads should be made by Graphic artist types who are more familiar with Flash. Thus the primary reason to use Java is to access some feature that flash has blocked in Flash.

    So if your goal with a Java ad is to circumvent something that Adobe has blocked then it probably should remain blocked. On top of that most users have turned off Java so it can't be to reach a wider audience.

    So when Yahoo allows advertisers to use Java they knew perfectly well that the advertisers were up to no good whatsoever. Their acting surprised that some of the scumbags took it even further is total BS.

    Basically at this point, anyone who has Java turned on in the browser is the same as having a house with a weeks worth of newspapers stacked up at the front door. Effectively a greeting card inviting the criminals in.

I thought the coverage of Java Applet Ads would be pretty poor. I am not sure of the exact stats but with mobile devices growing this number must also be in freefall.

        The only legitimate sites that I see where a java applet is a critical feature are older science websites. Astronomy calculators would be a common example.

  • As usual (unfortunately). Both the article and the summary are pathetic examples of journalism which should try to at least inform.
    For instance, it would be useful to know (at a minimum) which OSs, browsers, etc are vulnerable, whether any of the virus detection programs will block or remove the malware and what effects the malware has on systems when they are infected.
    In other words, this article is just "scareware" warning about some unspecified threat to do something bad to somebody and no idea who, what

    • Did you even read the articles, or did you just click the first link in the summary and call it a day? The one linking specifically to Fox IT's blog, which is the source of this discovery, goes into great detail about this. They specifically mention the following:

      This exploit kit exploits vulnerabilities in Java and installs a host of different malware including:

      ZeuS
      Andromeda
      Dorkbot/Ngrbot
      Advertisement clicking malware
      Tinba/Zusy
      Necurs

        But do any of these run on Linux.. or Mac OSX?
        I guess we should just assume that they all run on Windows although the article is silent on this subject.
        Does any antivirus program detect or block any of these?
        What should I do if I think I have been "exposed"?

        Useless articles.

        • None of those malware packages are new. They've been covered numerous times in the past. Google them up yourself if you weren't paying attention for the last 6 years. I certainly don't want to have to read through a bunch of information that I already know because it's not exactly new.

    Hence why I advise people to install AdBlock on their browsers. The way things have been for the pas few years, it's probably more effective than antivirus software. (Before you flame me, I am speaking tongue-in-cheek. You really should have both.)
  • reminder that Java has become an Internet security menace."

    The big three browsers can trivially block Java, through something as simple as "click to play", or "always launch plugins from this site". Any browser that auto-executes stuff by default is broken.

    On the other hand, I've had a malware distribution attempt via Javascript. It's certainly designed to attack Chrome, since it wipes the previous page content and URL, replacing it with its own.

    Oh, and a trivial Javascript exploit that browsers took 10+

  • "...reminder that Java has become an Internet security menace."

    Actually, the largest menace is Javascript. That's why so many people use NoScript.

    Any kind of in-browser active code execution will inevitably have security challenges.

    I don't have Java installed. I run linux, but Java is cross-platform, and I don't fall into the "it can't happen here" camp. Besides, I save a few hundred megabytes of disk space by not installing Java.

    Flash is another issue altogether. I follow one forum that autoruns Flash movie ads on occasion. If you hovered over the ad, it would enable sound too.Firefox used to lock up for a few minutes. Running with system load = 3 or 4, on a 2-core machine is begging for thrashing/near-lockup.

    I now use 2 browsers...
    1) one browser has Flash disabled entirely
    2) the other one I launch when I see a link to Youtube/whatever. When the video finishes, I close it. The taskbar has a mini-version of "top" running. Sometimes, after turning off the Flash browser, I'll watch the system load fall from 1.3 down to 0.3... satisfying.

    A/V doesn't protect against a lot of this stuff. Malwarebytes [malwarebytes.org] has a new anti-exploit beta [malwarebytes.org] for us Windows folks.

    From the FAQ:

    17- What techniques does MBAE use to detect and block exploits?

    MBAE incorporates multiple exploit detection and blocking techniques at different stages of the typical exploit attack to provide a truly complete solution against all types of current and future exploits.
      Stage 1 Layer: This layer of MBAE incorporates multiple techniques to detect and block exploits during stage 1 of the exploit attack, before the shellcode is allowed to run. In some cases, MBAE detects and prevents exploits before the operating system Data Execution Protection (DEP) protection.
      Stage 2 Layer: This layer of MBAE incorporates multiple memory protection and payload execution techniques which prevent exploits from executing their stage 2 payload, thereby protecting the computer even if operating system protections and stage 1 protection techniques have been bypassed.

  • Most people running something other than IE with an ad block or script block most likely never would have had any problems. My boss still likes IE for whatever reason, needless to say Im at his computer every month or 2 removing spyware, viruses or a total computer hijacking (pay us 100$ to unlock this pc). Last virus he picked up was from an ad on msn.
    • You can block ads and scripts in IE just fine. Heck, there are even built-in ways to do it, using filter lists from folks like EasyList (better known for their popular AdBlock Plus filter list). No need to download an extension (MS calls them "add-ons" but they are much the same thing) as long as you're using IE9 or newer, but ad-blocking and script-filtering are available at least as far back as IE6. There's also options like blocking using a HOSTS file or similar.

      Your boss's problem isn't that he uses IE,

If you have a procedure with 10 parameters, you probably missed some.
