US Researchers Release Rapid Internet Scanning Tool

University of Michigan researchers have created a tool that uses  a conventional server to conduct a scan of every Internet address in only 44 minutes. Zmap can be used by anyone with a fast internet connection. A tool called Nmap, used most notably in 2010 by the Electronic Frontier Foundation to determine the use of encryption online, conducted an Internet-wide scan in two to three months. The pace at which it works is slower because it keeps records for each outstanding request in the process. ZMap, by contrast, is a stateless process that has less overhead. The researchers say this allows packets to be sent 1,000 times faster than Nmap. It also gives them the 44-minute Internet scan. The researchers demonstrated the tool through several Internet-wide scanning experiments, including one to determine the pace at which organizations are deploying encrypted HTTPS and another that looked for host devices still using Universal Plug and Play following wide disclosure that it had a vulnerability. The researchers presented their findings at the recent Usenix security conference in Washington. (SlashDot)(The Washington Post)(ZMap)
