the diversity here is interesting. My hunch is that we are looking at 38 popped boxes (IPs are according to Philipps tarball, of course most of the IPs were running 2 relays as is economical for attacks):

The question to me is: Do they all have something in common? What was the vector of compromise?

Curiously enough, they all run Debian stable (according to the SSH version string "SSH-2.0-OpenSSH_6.0p1 Debian-4+deb7u2” *ALL* of them spit out on port 22 — no exception!).

Cheers,
Ralf
