Here’s what you find when you scan the entire Internet in an hour
“Until recently, scanning the entire Internet, with its billions of unique addresses, was a slow and labor-intensive process. For example, in 2010 the Electronic Frontier Foundation conducted a scan to gather data on the use of encryption online. The process took two to three months.
A team of researchers at the University of Michigan believed they could do better. A lot better. On Friday, at the Usenix security conference in Washington, they announced ZMap, a tool that allows an ordinary server to scan every address on the Internet in just 44 minutes.”
Using ZMap, the Michigan researchers found that over the last year, HTTPS use by the top 1 million Web sites (the red line) has increased by about 23 percent, and the number of HTTPS overall (the blue line) increased by almost 20 percent.
