IE Used To Launch Yahoo IM Clickfraud
An anonymous reader writes, "There's a new Instant Messaging worm in the wild that is taking the idea of Botnet clickfraud up a level. It trades in automated drones (prone to malfunction and detection) for real live people who (of course) have the option of not actually clicking anything, thus theoretically making their clicks harder to identify as 'fraudulent.' This IM attack doesn't even need a victim to physically run anything to become infected — simply visiting a certain site in Internet Explorer will cause the files to download and start sending infection messages. At this point, their homepage is changed to a site using Mesothelioma (a rare form of cancer) to ring up high-paying results on the perpetrators' Google ads. As the researcher who discovered the infection notes, 'It's way, way harder to trace some random boob who has a ton of (partially) unconnected people shunting IM links all over the place. Try staying anonymous as a Botnet owner who just had the entire details of his server splattered across the net by Shadowserver. What will be interesting to see is if some of the smaller Botnet guys ditch their technical woes and jump on the much-easier-to-maintain IM bandwagon to get their clickfraud kicks.'"
Can someone translate the summary into English?

At this point, their homepage is changed to a site using^H^H^H^H^H about Mesothelioma (a rare form of cancer) to ring up high-paying results on the perpetrators' Google ads. High-paying, because mesothelioma is an uncommon word.
For those who didn't RTFA, here's another summary:
You get an infected Yahoo IM. In addition to propogating, it turns your IE home page into an ad-filled page. The ad page works like Google's adsense, only in this case instead of Google paying a legitimate web site when people click-through the ad, Google or some other company winds up paying the scammer or his cronies.
Because of the way it works it's a lot harder to detect than automated fraud or paid-human click fraud. Because the end user will likely click on the ad only if he's actually interested in it, the company that originated the ad might not even consider it fraud - he's just found a live potential client.
What makes it fraud is that the end user's web page has been hijacked. In other words - it's spyware/adware.
Workaround: Don't use IE, and use a malware-detector that detects and blocks Yahoo IM Malware.
Knowledge is how to play a game, intelligence is how to win, wisdom is knowing what game to play.
If you want to screw over some lawyers and Google, search for mesothelioma and click on the AdSense links.
Just another example of clever people taking advantage of anyone that is unfortunate enough to not know to click on unwanted popup things that ask them to click here, or enter your financial information etc.
The internet will not be safe, ever, because of those people. Yes, "click here to win a date with name-a-rising-star" will always find its way to someone that thinks there is some remote possibility that Bill Gates will pay you to forward emails, or that a music hall-of-famer needs a date from someone just like them. The human factor in security will always be the weakest link. ALWAYS.

Google does offer a public tool for estimating cost-per-click and position based on keyword, match type, and maximum bid. Toying with it...
For 'mesothelioma', Exact Match, the current estimate seems to be that a max bid of $100/click will normally land one in position 1-3 and cost $44.23/click -- which is very, very good. It's not the highest I've seen (and there are ones that have both significantly higher CPC and probably a much higher clickthrough rate given greater applicability, judging from some experimentation... but I'm not here to help the click-spammers increase their take), but it's up there.
The exploit changes their homepage to some page with Google ads about mesotheleoma, and the bad guys get money from the clickfraud (people seeing impressions on an expensive Google keyword, most likely because liability lawyers are suing over it or something, and looking for people to join various class action suits where the lawyers can get big money).
