Anonymous proxies used for "Shotgun DDoS" attacks


Softpedia - (International) Security researchers at Incapsula released findings from a one-month study revealing that 20 percent of all Layer 7 application layer distributed denial-of-service (DDoS) attacks from January - February were "Shotgun DDoS" attacks carried out through anonymous proxies to bypass mitigation systems by spreading across multiple internet protocols (IPs) and multiple geo-locations. Approximately 45 percent of the incidents originated from addresses in the Tor anonymity network and 60 percent of them employed Tor's Hammer denial-of-service (DoS) tool, which carries out low-and-slow power-on self-test (POST) attacks.
