IPv4 Census - Port scanning /0 using insecure embedded devices

This is pretty amazing if true. A census - not a sample! - of the entire IPv4 address space tells us a lot about the internet.

Where is the source code to his bot? I don't see it. Maybe I over-looked it. Without seeing source code, I find this story hard to believe.

Also, who is the person behind it? The PGP key published is to an anon Gmail account internetcensus2012@mail.com.

If the story is true, the legal liability of doing this may be the reason the author is hiding his/her identity.

It's pretty rad. That's an effectively big botnet. I wonder if it's possible to have a breakdown of residential vs enterprise for the boxes he's connected to. Maybe a sample of the local subnet? Or doing port scanning on the internal network too, and judging based on network size?

What I really wanted to see is whether anyone has found the readme file and contacted the author. Unfortunately the author doesn't mention this.

I'd expect that a couple of hosts he got into were honeypots.
