Botnet caught red handed stealing from Google
And Yahoo!... and Bing
A recently discovered botnet has been caught siphoning ad revenue away from Google, Yahoo! and Bing and funneling it to smaller networks.
According to researchers at Click Forensics, computers that are part of the so-called Bahama Botnet are infected with malware that sends them to counterfeit search pages instead of the real thing. They look authentic, and with the help of DNS poisoning routines, they even display google.com yahoo.com or bing.com in the address bar.
But the search results returned by these bogus sites have been ginned in some significant ways. While links contained in the organic results ultimately lead to a real site, browsers are first redirected to a series of ad networks that receive a small referral fee. Sponsored links, which typically pay the real search engine each time they are clicked, have also been jury rigged so a smaller ad network gets paid instead.
"The idea is to make money through click fraud," said Matt Graham, a risk analyst at Click Forensics that provides auditing services to advertisers. "When those people actually do searches, that's when these guys can display these ads hidden in the organic search results."
As this video demonstrates, the faux websites have precisely the same look and feel as the real Google, Yahoo or Bing. But traffic analysis tools show the infected computer is really connected to an impostor server with the IP address of 64.86.17.56. The counterfeit site actually pulls the results from the search engine it's spoofing before they're doctored, furthering the illusion that everything is on the up and up.
A Google spokeswoman said: "We are investigating and monitoring this issue just as we investigate and monitor many other botnets and schemes every day." A Microsoft spokesman declined to comment and representatives from Yahoo hadn't responded by time of writing.
The Bahama Botnet, so named because it initially used compromised servers from that country, has already been implicated in the rogue anti-virus ads that recently found their way onto the website of The New York Times. It's also been known for its mastery of search engine optimization techniques that send people to malicious websites when they search for current events topics.
Now, instead of attacking average joes with sloppy PC hygiene, it's turning on three of the world's biggest search engines. Graham said the number of infected machines he's observed is in the thousands. And that suggests the amount of damage is still relatively modest. Should the Bahama Botnet grow, it will be worth watching to see how these sleeping giants respond. ®

What's that FF plug-in?
In the video, it looked interesting.
RE: Re: Maybe NOW...
We'll have to see.
Up until now, botnets have only been annoying users and people who run gambling sites.
Now that the Big Lads are getting their pockets picked, I suspect we'll find out...

Well you my friend certainly aren't going to have a problem. But those souls whose Hotmail accounts have a password of 123456 are the botnet's target.
