Volumetric attacks are easy to generate by employing simple amplification techniques, so these are the most common forms of attack. Volumetric Attacks send high volumes of traffic in an effort to saturate a victim’s bandwidth. Syn Flood and Ping of Death are some examples. Such attacks consume all the processing capacity of the victim or other critical resources (a firewall, for example), resulting in service disruption. Protocol Based Attacks focus on exploiting a weakness in Layers 3 or 4 of the protocol stack. These attacks exploit a weakness in the Layer 7 protocol stack by first establishing a connection with the target, then exhausting server resources by monopolizing processes and transactions. But according to information obtained by KrebsOnSecurity, the administrator of WebStresser allegedly was a young man in Serbia named Jovan Mirkovic.The goal of DoS or DDoS attacks is to consume enough server or network resources so that the system becomes unresponsive to legitimate requests:Īpplication Layer Attacks go after web applications, and often use the most sophistication. authorities would say who was arrested in connection with this takedown. The U.K.’s National Crime Agency said WebStresser could be rented for as little as $14.99, and that the service allowed people with little or no technical knowledge to launch crippling DDoS attacks around the world. In a separate statement released this morning, Europol - the law enforcement agency of the European Union - said “further measures were taken against the top users of this marketplace in the Netherlands, Italy, Spain, Croatia, the United Kingdom, Australia, Canada and Hong Kong.” The servers powering WebStresser were located in Germany, the Netherlands and the United States, according to Europol. “The damage of these attacks is substantial,” reads a statement from the Dutch National Police in a Reddit thread about the takedown.”Victims are out of business for a period of time, and spend money on mitigation and on (other) security measures.” WebStresser was one of many so-called “booter” services - virtual hired muscle that anyone can rent to knock nearly any website or Internet user offline. The action, dubbed “Operation Power Off,” targeted (previously ), one of the most active services for launching point-and-click distributed denial-of-service (DDoS) attacks. Investigators say that prior to the takedown, the service had more than 136,000 registered users and was responsible for launching somewhere between four and six million attacks over the past three years. and the Netherlands on Tuesday took down popular online attack-for-hire service and arrested its alleged administrators.
