In 2015, Soldier of FORTRAN gave a talk about finding mainframes on the internet. It was a small, simple talk about some of his finds and the misadventures of using Nmap and friends. Since then he turned his operation in to a well oiled machine and has, essentially, completed his project. This talk will be about all the new mainframes he discovered, significant changes to Nmap and how it detects mainframes, including a discussion around Nmap and its change process, automating the discovery and posting of mainframes to Tumblr. It will also cover cow easy it was to use a VPS and massscan to scan the entire internet and how to feed that data in to Nmap so you can do this yourself!
