In this paper, we presented an empirical study of DDoS
botnets. More specifically, we studied 35 C&C servers
related to the DirtJumper family of malware. We observed
almost two thousand DDoS attacks and performed
an analysis regarding various aspects that enables us to
obtain insights into such attacks. Furthermore, we complemented
this C&C-centric vantage point with a brief
analysis of two DDoS attacks from the victim’s side.
