More than 2 million servers still running on vulnerable legacy software

BetaNews reported this week that more than two million web servers worldwide are still running on outdated versions of Microsoft Internet Information Services (IIS) software, according to research from CyberNews.

IIS is the third most popular suite of web server software with more than 12.4 percent of the global market and at least 50 million websites and web applications are powered by it.

BetaNews explains that “older IIS versions from 7.5 downwards are no longer supported by Microsoft, and as with other types of outdated server software, all legacy versions of Microsoft IIS suffer from numerous critical security vulnerabilities, making them an attractive target for threat actors.”

Most vulnerable IIS web servers are located in China, followed by the United States.
