According to Matherly, the list of top affected organizations includes IT giants like Amazon, Verizon Wireless, German ISP Strato, OVH, 1&1 Internet, and Comcast.

The most affected product is Apache HTTP Server (httpd), in particular versions 2.2.22 and 2.2.15. Top operating system is Linux 3.x, followed by Linux 2.6.x and Windows 7/8. According to the report published by Shodan, more than 70,000 devices run services with expired SSL certificates.
