Two Major Ad Networks Found Serving Malware

Trailrunner7 writes "Two major online ad networks — DoubleClick and MSN — were serving malware via drive-by download exploits over the last week, experts say, after a group of attackers was able to trick the networks into displaying their ads by impersonating an online advertising provider. The scheme involved a group of attackers who registered a domain that was one letter away from that of ADShuffle.com, an online advertising technology firm. The attackers then used the fake domain — ADShufffle.com — to dupe the advertising networks into serving their malicious banner ads. The ads used various exploits to install malware on victims' PCs through drive-by downloads, according to information compiled by security vendor Armorize."

    The trust model of online advertising is in my opinion fundamentally broken. A big part of the security model of the web is domain-based - e.g. the same origin policy - but this goes down the drain with third party ads hosted on yet another third party's server.

    With online advertising it was for the first time possible to measure the effect of ad campaigns better than "how many saw it and did we sell more after it?" What did this bring us? "PUNCH THE MONKEY!", "LOOK AT THE BLINKING LIGHTS!", "BEEP BLOOP BEEEEEP!!!" and perhaps most insidiously it broke the domain-based model of trust on the web since everything had to be put on the advertising hosters' servers to deter click fraud and whatnot.

    AdBlock doesn't just save you bandwidth and reduces the annoyance of browsing the web, it is also one of the best tools for avoiding drive-by malware from ads.

    What sucks is that I'd actually like to support the sites I frequently visit, and ad views clearly have a significant effect on their various bottom lines,

    Ad views have become the defacto micropayment system. If we had an alternative, sites wouldn't have to be dependent on privacy-invasive and security-breaking ad systems. I'm sure that many would anyway, but they would at least have other options.

    but that same responsible part is also well aware that any kind of commercial interaction with said pornographers has a suspicious way of going horribly wrong.

    Micropayments could solve that problem too - anonymous microcash would be almost completely immune to the kind of abuses that you are avoiding.
