Mass Scanning the Internet: Tips, Tricks, Results
Robert Graham
Paul McMillan
Dan Tentler
Scanning the net -- the entire net -- is now a thing. This talk will discuss how to do it, such as how to get an ISP that will allow scanning, tools to do the scanning (such as 'masscan'), tools to process results, and dealing with abuse complaints. We Internet, such as all the SCADA/ICS systems we've found. We've only scratched the surface -- the Dark Internet of Things is waiting for more things to be discovered. We expect the audience to have a working knowledge of existing portscanners, namely nmap.

Robert Graham is the CEO of Errata Security, a pentest/consulting firm. He's known for creating the first IPS, the BlackICE series of products, sidejacking, and masscan. In his spare time, he scans the Internet. He has been speaking at several conferences a year for the past decade.
