    I'm not getting any flags from ESET as of yet.

    Brian Krebs stated via his Facebook page:
    Brian has been contacted via Twitter and other social media that it would appear NBC have taken action although there have been no statements released by NBC.

    This is why I think computer users who say they only need to utilize "common sense" when surfing the net are kidding themselves.
    Would common sense have told them to stay away from nbc[.]com today?

    I tend to agree as it only takes that one time for even a reputable site to become compromised. Common sense tell me to check my brakes on my vehicle at certain intervals but it doesn't mean that my brake pads cant't crack or glaze over from heat making stopping distance greater.

    Saved by my abhorrance of anything to do with NBC.:D
    Just went there and no redirects--that was on my Chromebook.

    Well, at least I know that Mozilla is quick on their toes

    Firefox browser blocked it.

    It appears NBC Fixed the problem, the site is no longer blocked.

    Agreed. The attackers go wherever they can that gets high exposure. Even if they don't hack a site directly, they do like to get into banner ad networks when they can (and these things happen more than what gets reported; NBC.com is justn newsworthy and worth a public warning).

    At the time you posted, ESET didn't block the website any more as the malicious iframe was already removed.

    I agree with you, however that doesn't mean that you shouldn't use common sense when navigating the web. It might not save you every time (that's why you have security software or other security measures installed on your computer), but it helps to greatly reduce the number of attacks.

    Yes I agree. Common sense may not actually detect & remove malware but it is one layer of not getting it in the first place. ;)

    I can't even remember the number of times I've said the same thing. Some years back common sense would say to stay away from porn sites. Nowdays, common sense tells me only to visit those. :D (Just kidding... I don't visit such sites. I promise. :ninja: )

    Big business sites that have a lot of public views and/or interaction on their websites, like NBC, are usually hacked by groups like 'anonymous'. They have stated that all western governments and large corporations will be targets of hacking. The reason is obvious ... it gives them lots of air time to spew their political views. No announcements from them on this one as yet. If NBC finds out the source of the hack can they keep it under wraps and still meet their mandate to deliver news. It kind of puts them between a rock and a hard place.

    You mean the ESET blacklist had been lifted.
    Article

    Facebook and Google had also temporarily blocked access to the affected sites as well.

    According to VirusTotal and ZeroVulnerabilityLabs, very few AVs were catching this exploit.

    In the Eset article, I notice from the screen shots of the redirected sites, that one exploit is Java, as the code attempts to load a file (probably .jar, but it is blacked out). This requires that Plugins be enabled globally, or the exploit code doesn't run, since, if white-listed per site, the Plugin is not enabled when redirected to a non-white listed site.

    Sans.edu in its diary that ronjor cited, mentions a PDF exploit. This also would require a potential victim to have Plugins enabled globally.

    The Eset article mentions that other files are downloaded, and its screen shot shows javascript code. In a similar fashion, the potential victim would need to have javascript enabled globally for that code to execute.

    Hi Rmus,

    What would likely happen to someone who didn't have java or a standalone pdf reader installed, but who just used Firefox with it's built-in pdf reader and nothing else?
