I felt carniwwwhore needs some visuals, so I've been playing with pychart lately, and I wanted to point out some aspects of the data which are easily accessible with carniwwwhore.
The data used here was gathered using the anonymous xmpp sensor network, which is not that exact as source, as users may nmap their own scanner for testing purposes, or fail to install properly.
The code which generates charts for the data is not in git yet, but all charts are plain copies from 'what exists' already.

distribution of the top 100 rejects for the last 2 weeks
The top 10 of the top 100 rejects make a large chunk of the total.

For tcp/port 15436 I have no idea what is meant to be served on the port, the distribution of the top 100 hosts looks like this:

tcp/port 9415 was more interesting, google told me it was the port of the koobface proxy.

So I had a look on the distribution of attacks over the last 6 months for 9415 and 15436:

Had more to write, but need to catch a train now.
