We introducetemporal lensing: a technique thatconcentrates a relatively low-bandwidth flood into a short, high-bandwidth pulse. By leveraging existing DNS infrastructure,we experimentally explore lensing and the properties of thepulses it creates. We also empirically show how attackers canuse lensing alone to achieve peak bandwidths more than anorder of magnitude greater than their upload bandwidth. Whileformidable by itself in a pulsing DoS attack, attackers can alsocombine lensing with amplification to potentially produce pulseswith peak bandwidths orders of magnitude larger than their own.
