Google: Attack code more likely on Microsoft IIS

Web sites running Microsoft Corp.'s Web server software are twice as likely to be hosting malicious code as other Web sites, according to research from Google Inc.

Last month, Google's Anti-Malware team looked at 70,000 domains that were either distributing malware or hosting attack code. "Compared to our sample of servers across the Internet, Microsoft IIS features twice as often as a malware-distributing server," wrote Google's Nagendra Modadugu, in a Tuesday blog posting.

Together, IIS (Internet Information Services) and Apache servers host about 89 percent of all Web sites, but collectively they're responsible for 98 percent of all Web-based malware.
