From Russia With Malware

An online business based in Russia is paying Web sites 6 cents for each machine they infect with adware and spyware, according to security researchers who call the practice "awful."
IframeDollars.biz says it pays Webmasters to place a one-line exploit on their sites. The code exploits a number of patched Windows and Internet Explorer vulnerabilities, including some that go back as far as 2002. Systems that haven't been updated would be vulnerable to the exploit. According to analysis done by the SANS Institute's Internet Storm Center, the exploit drops at least nine pieces of malicious code--including back doors, other Trojans, spyware, and adware--on any PC whose user surfs to a site that hosts the exploit code.
IframeDollars says it pays $61 per thousand unique installations, or 6.1 cents per compromised machine, to any site that signs up as an affiliate.
According to the Internet Storm Center, companies can prevent the downloading of adware and spyware from iframeDollars' servers by blocking the IP address 81.222.131.59.
