“Processing these messages consumes a lot of resources, which overloads victim devices and prevents them from accepting legitimate requests,” the Kaspersky report said. “As such, the researchers found more than 386,000 devices giving an amplification factor of over 100, with more than 97,000 of them over 500, and 192 of them over 51,000.”Īnother new attack first identified by Nexusguard named Black Storm bombards communications service provider (CSP) networks with requests to access to closed ports. “If a request for access to a banned resource is sent under the guise of the victim, the response from a middlebox can be significantly larger,” the Kaspersky report said. The third quarter also ushered in two new DDoS attack vectors, the analysts found.ĭuring Q3, a team from the University of Maryland and the University of Colorado at Boulder figured out how to exploit TCP protocol to attack security devices like firewalls, deep packet inspection (DPI) tools and network address translators (NAT) often called “middleboxes” because of their position between the client and server. “This may be due to the decreasing number of attacks lasting 50 hours or more and a rise in relatively short attacks,” the report added. ![]() “For two more days, August 21 and 22, the daily count of five thousand was exceeded and over three thousand attacks were detected on August 2 and 6, September 16, 18, 19 and 22.”Īnd while the volume of DDoS attacks spiked, their duration declined, the researchers found. “July started off relatively quietly, but towards the middle of the month the average daily count of DDoS attacks exceeded 1,000, with a whopping 8,825 attacks on August 18,” the report said. The latest DDoS report for Q3 from Kaspersky details a record-breaking frenzy of recent activity by threat actors. ![]() The third quarter saw the sheer volume of distributed denial-of-service (DDoS) attacks surge to several thousand hits per day, signaling a re-distribution of tactics by malicious actors away from cryptomining and toward the use of DDoS as a tool of intimidation, disinformation and straight-up extortion.
