This is a snapshot of Amazon AWS port 80 application server banners for the time period spanning January 1st through January 10th (inclusive).
This data is derived from the scanning of all AWS CSP guest instances (5,156,864 – based on disclosed subnet ranges) where the port 80/tcp was unfiltered and accessible from the Internet. The average number of hosts that responded to port 80/tcp scans on the AWS subnet was 431,533, or only about %8.4 percent of all AWS allocated subnets.
From the scan 119,602 banners were discovered on port 80/tcp, this chart depicts the Top 20 application servers detected.
Next, we see the application stacks discovered in the same scan. Not every application server has a corresponding application stack (e.g. not ever Apache/2.2 server has PHP/5.2 installed) which accounts for the 80,731 servers with an application stack of ‘none’.
Excluding the ‘none’ count, we discovered 39,011 application stacks (119,742 including the ‘none’ values)
I hope you find this data useful.
Note: No servers were harmed in the collection of this data.
