The Internet has seen a continuous rise in malicious traffic including DDoS and worm attacks. In this paper, we study the effect of malicious traffic on the background traffic by gathering traces from two different locations. We show that the malicious traffic causes the increases of DNS latency by 230% and web latency by 30% even on highly over-provisioned links. Using a packet-level simulations based on an empirically derived model of the worm, we demonstrate that the effect of worm- infected hosts can be disastrous when they trigger a DDoS attack.
