Over a slow weekend, I decided to make my first attempt at running a Dionaea honeypot to catch some malware samples to play with. Armed with this simple guide and a micro Amazon EC2 instance, the whole thing was up and running in well under an hour. For my first attempt, I stuck with the default configuration. I imagine there’s a lot of improvements and tweaks that I entirely missed.

It didn’t take long to start getting hits, and after three days I stopped. The honeypot had produced a 6.1gb log, and the instance was beginning to complain that there was no space left on the drive to write to. I had managed to snag three binaries:

47b2e95136e660522067221ae405025c
9b9df225dfc4b43c727b9177e9eb0678
fd1fb45d7ca1eeef06f5d46a3e9a3d2f

It had been surveyed by 2387 unique IP addresses over 10 different protocols. However, I found that all three binaries on the system were the responsibility of one hacker (group?), originating from a Ukrainian IP address.

We can see the connections here:

And here we have the downloads:

The next interesting point is the urls in the log. The majority of urls captured seemed primarily used for spam. Some quick stats:

3059 mail login attempts
293845 advertisement urls
71 forum registrations

Next up, fun with Kippo.
