Microsoft IIS Sees Triple-Digit Spike in Cyberattack Volume

Internet Information Services (IIS), an extensible web server originally created by Microsoft for use with the Windows NT family, saw a whopping 782x increase in cyberattacks during the second quarter, according to eSentire’s latest report based on data gathered from 2,000+ proprietary network and host-based detection sensors distributed globally across multiple industries.

The report found that attacks on IIS increased from just 2,000 to a statistically significant 1.7 million, quarter-over-quarter. Most sources targeting IIS web servers originated from China-based IP addresses. According to Shodan, there are 3.5 million IIS web servers exposed around the globe, with 1 million exposed in China alone.
