    I think this is called the "Dancing Pigs Effect". Security should focus more on educating people for common sense rather than constantly hunting for 0days (not the people shouldn't try to patch vulnerabilities). Simply disabling browser scripts does a hell of a lot more than running antivirus.

    The whole thing is so patently infantile, so foreign to reality, that to anyone with a friendly attitude to humanity it is painful to think that the great majority of mortals will never be able to rise above this view of life.

    Your other point as well has got me thinking in that I've no idea what being hacked looks like unless it's obvious. I just assumed being hacked would mean that your finances might be in jeoparday. I imagine a lot of people think that.
    The thing is - most people would trust a reputable site and "let their guard down" which makes it the perfect vector of attack.

    That's exactly what exploit packs take advantage of. If a hacker buys an exploit pack and hacks a "reputable" site, he can put the exploit pack in that site and anyone who visits it has the potential to be infected. Theoretically this could even happen to Ubuntu Forums, but because this site has good security, and because many people who visit this forum are using a computer with GNU/Linux, it would be a very poor attack vector. But many innocent sites (especially blogs) can become zombies spreading malware. So don't trust anything 100%, even if you know the owner of the site would never put up malware!

    It's not just legit/reputable sites being compromised directly. What I see most often when I'm actively monitoring are malicious ads. Sure, there are many, many small and large sites with out of date web applications, db flaws, server software, things like that, and they do frequently get compromised. But from an ROI standpoint, nothing beats getting a malicious ad onto a widely-used legitimate platform, and it happens to the biggest ones all the time. Individually they may be relatively short-lived, but during their lifetimes they could compromise every visitor to every site that the ad platform has cycled that advertisement onto, no additional clicks necessary. And nothing the site owners can do except report the ads and hope they are removed, or stop running that ad platform.

    I always advise users to block ads.

    Agreed. I remember a (semi) popular forum that got tagged as malicious because of their ads. I know this is a popular method because it bypasses the main site completely and puts the blame on the company serving the ads.

    Right, but those ads are often "legit", but were compromised at some stage, aren't they? I seem to remember reading somewhere that more malicious ads are malicious because the were compromised than malicious to start out.

    And I always block ads, but not because of malware but because they are annoying as hell! I just disable JavaScript, Java, and Flash in Chromium (I'm still waiting for Chrome's extensions API to be improved so that the NoScript developer can port it to Chrome) to protect from malicious scripts.

    I don't think legitimate ads themselves get compromised so much as fraudulent "companies" place ads with platform providers, sometimes going as far as to submit one advertisement for review that is harmless and switching to the malicious ad later. There's just not a very robust review process at a lot of platforms, and I wouldn't be surprised to find that submission is automated.

    And yes, even the ones that aren't malicious are annoying.

    Ok, so by now everyone here has read about the Tumblr Blog worm. http://www.nbcnews.com/technology/te...isitors-825075

    A reputable website. Hacked. End-user data (and perhaps worse) released. A few hours later, the fix was made, but some fairly high-traffic blogs like CNET and Verge were defaced. What happened beyond that is unknown.

    So I guess the moral to this thread that it's not paranoia to be security conscious but more of a case that you can never be too careful.
