I’m in Luxembourg to attend the first edition of the CTI Summit. There was an interesting keynote performed by Patrice Auffret, the founder of Onyphe, about “Ethical Internet Scanning in 2022”. They are plenty of online scanners that work 24x7 to build a map of the Internet. They scan the entire IP addresses space and look for interesting devices, vulnerabilities, etc. Big players are Shodan, Onyphe, Censys, ZoomEye, etc.
