HN Theater @HNTheaterMonth

That's probably the DEFCON talk the parent poster is talking about:

Massscanning the Internet - Defcon 22 (2014)

These guys will tell you: https://www.youtube.com/watch?v=UOWexFaRylM

It is trivial to scan the whole ipv4 address space. I think the guys in this video did it in 40mins or so while presenting.

Scanning the internet isn't that slow

He gave a talk about massscan at this year's DEF CON: https://www.youtube.com/watch?v=UOWexFaRylM which is quite fun to watch.

There's a great talk from Defcon 22 on using Massscan for security research:

As a side note, I recently learned that it was possible to scan the whole Internet in a few hours on a regular connection: https://www.youtube.com/watch?v=UOWexFaRylM

Mass Scanning the Internet is a must-watch.

Edit: it's available youtube : https://www.youtube.com/watch?v=UOWexFaRylM

Viss is pretty funny on this one. A complaint form that goes to nowhere? Turn it into a tumblr feed!

In passing he also mentions a Tumblr posting screenshots from scans. This appears to be the page: http://mainframesproject.tumblr.com/

+1 to this. During the presentation they scan the entire internet for open VNC ports that do not require authentication. There were many found (thousands?), the most surprising being a mainframe that looked like it controlled a railway interchange. I was the guy who gave them the iPhone backdoor port ;-)

This was demonstrated at 30C3 last December as well. I still have the screenshots of the hits on the firewall logs from the various servers I had up at the time.
