According to IBM Managed Security Services data, the vast majority of DDoS attacks come in one of two flavors: SYN flood attacks, in which bad actors send multiple SYN requests to a victim’s webserver in an attempt to consume enough resources to render the system unresponsive, and UDP/DNS attacks on network layers 3 (network) and 4 (transport), also known as reflection attacks.DDoS is a recurring premeditated attack on a company’s web infrastructure. Raven-Storm can deal with strong servers and can be optimized for special targets.Distributed denial-of-service (DDoS) attacks have been all over the news in recent months, with hacktivist groups taking major targets completely offline. Raven-Storm aims to test, understand, and learn from stress-testing attacks.
The tool in question, dubbed the Saphyra iDDoS Priv8 Tool, targets network layer 7 (application) and results in an HTTP flood DDoS attack. With this in mind, we decided to take a look at a newer DDoS tactic. Slowloris Many of the more intricate low and slow DDoS attack types rely on easy-to-use tools, yielding denial of service attacks that are much harder to detect.We know, however, that attackers are constantly tweaking their techniques. Open source DDoS mitigation tools detect, protect, and mitigate attacks on the infrastructure.This powerful, robust tool is among Anonymous’ current DDoS attack tools of choice. Open source DDoS mitigation software helps organizations that deal with a virtual or cloud server.

Pserver name Shows The communities best stresser is backAn HTTP flood attack is a type of layer 7 application attack that utilizes the standard, valid GET/POST requests used to fetch information, as in typical URL data retrievals, during SSL sessions. Eu is a recent DDoS-as-a-Service tool. Raven (abbreviation) is designed to help you to test, understand, and learn from stress-testing attacks.This is the Linux app named LOIC - DDos-attack tool. Takedown WiFi access points, devices in your network, servers, services, and Bluetooth devices with ease. What Is an HTTP Flood Attack?Raven-Storm is a powerful DDoS toolkit for penetration tests, including attacks for several protocols written in python (3.8). Other modifications of this tool are called Sadattack, Thor and Hulk.
This would allow for more than 1 million possible combinations of user agent string/referrer instances. Saphyra iDDoS Tool script headerThe script contains over 3,200 unique user agent strings and over 300 unique referrer field strings. Saphyra iDDoS Tool Command Line InterfaceFigure 2. Let’s take a look at this relatively simple script to understand how it operates and why it is hard to defend against.Figure 1. How Saphyra WorksThe Saphyra iDDoS tool is a Python script that can be run on virtually any device, including mobile phones.
Note the random GET request as well as user agent/referrer fields.User-Agent: Mozilla/5.0 (Macintosh U PPC Mac OS X de-de) AppleWebKit/418 (KHTML, like Gecko) Shiira/1.2.2 Safari/125Accept-Charset: ISO-8859-1,utf-8 q=0.7,* q=0.7Referer: ].y`y.U.d.n.cMU.Bjf.Ugjt\SyjT\z.d.A^qX…) tells Nginx to redirect all GET requests that have any characters with = between them and redirect them to 444 (No Response).The example GET request below shows the equal sign that is common to all requests:GET /?uQQ[oKYF%7DH=TPTYKsO%257D%257E%255C HTTP/1.1This tactic can be used on other web platforms as well. Example of referer strings in the scriptBelow is what the traffic looks like. Example of user agent strings in scriptFigure 4. No cache: By requesting the HTTP server for no cache, the sever presents a unique page for each request.Figure 3.
As a secondary tactic, consider a managed security solution that deflects and absorbs DDoS traffic before it reaches the target. The best defense is a comprehensive incident response plan, including failovers and a methodology for identifying, analyzing and neutralizing the threat. Distinguishing Between Legitimate and Malicious TrafficWith some DDoS attacks, it’s difficult to determine what traffic is legitimate and what is malicious.
