Threat actors have found a new way to optimize resources available to them for launching highly effective distributed denial-of-service (DDoS) attacks. Instead of using a DDoS botnet to direct a sustained stream of denial of service traffic at a single target, some attackers are now using their attack infrastructure to direct short bursts of traffic at multiple targets. The attack strategy seems designed to double a botnet’s output while being as effective as the usual longer-duration DDoS attacks. In the gaps between the pulses, threat actors appeared to be switching targets on the fly.”]
