Oh, sorry. I thought this was obvious from it's name and that I
mentioned it is a trojan.
I got the link to the drweb.com page from https://archive.fo/8LmBS which
is a copy of a short article in softpedia.
The Website I initially linked seems to hold a copy of one version of
the trojan's source code or some relevant/important part of it. Knowing
Germanys weird position on exploits, virus, etc I will not copy anything
from there in the email for my own legal safety.

softpedia quotes:
Dr.Web security researchers, the ones who have discovered this threat,
say the trojan seems to infect Linux machines via the Shellshock
vulnerability, still unpatched in a large number of devices.

The trojan, going by the generic name of Linux.DDoS.93, will first and
foremost modify the /var/run/dhcpclient-eth0.pid file in such a way that
its process is started with every computer boot. If the file doesn't
exist, the trojan will create it itself.


drweb.com:
The Trojan for Linux designed to carry out DDoS attacks. It is spread
presumably via ShellShock vulnerabilities.

At launching, it checks for the presence of
/var/run/dhcpclient-eth0.pid. file. If the Trojan cannot find this file,
it attempts to register itself in autorun.
