Headquartered in California, it has been a subsidiary of Microsoft since 2018. It provides access control and several collaboration features such as bug tracking, feature requests, task management, continuous integration and wikis for every project.

It offers the distributed version control and source code management (SCM) functionality of Git, plus its own features.

is a provider of Internet hosting for software development and version control using Git. As a secondary tactic, consider a managed security solution that deflects and absorbs DDoS traffic before it reaches the target.Optional (required for creating and joining repositories, and browsing all repositories.) The best defense is a comprehensive incident response plan, including failovers and a methodology for identifying, analyzing and neutralizing the threat. With some DDoS attacks, it’s difficult to determine what traffic is legitimate and what is malicious. Distinguishing Between Legitimate and Malicious Traffic Consult your server documentation for instructions to create a rewrite mod.

This tactic can be used on other web platforms as well. The example GET request below shows the equal sign that is common to all requests: Referer: ].y`y.U.d.n.\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).

  • No cache: By requesting the HTTP server for no cache, the sever presents a unique page for each request.įigure 3.
  • Persistence: The tool uses standard HTTP commands to force the server to maintain open connections by using keep-alives with definable time window.
  • Referer spoofing: This enables the sending of incorrect referer information in an HTTP request to prevent a website from obtaining accurate data on the identity of the webpage previously visited by the user.
  • Obfuscation of source client: By using a list of known user agents, the user agent is constructed as a random value out of the known list.
  • The Saphyra tool operates using a variety of techniques, including: The tool interface boasts an affiliation with almost 1.8 billion bots, but this could not be confirmed at the time of analysis. This can result in website failure as the server becomes quickly overwhelmed by the volume of requests. Its main purpose is to generate unique requests, avoiding or bypassing caching engines and directly impacting the server load. When the tool is executed, a unique combination is sent in the form of HTTP requests to the victim’s website. This would allow for more than 1 million possible combinations of user agent string/referrer instances. The script contains over 3,200 unique user agent strings and over 300 unique referrer field strings. Saphyra iDDoS Tool Command Line Interfaceįigure 2. Let’s take a look at this relatively simple script to understand how it operates and why it is hard to defend against.įigure 1. The Saphyra iDDoS tool is a Python script that can be run on virtually any device, including mobile phones. An HTTP GET/POST flood is a volumetric attack that does not use malformed packets, spoofing or reflection techniques. What Is an HTTP Flood Attack?Īn 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. Other modifications of this tool are called Sadattack, Thor and Hulk. This tool was responsible for taking down the NASA website earlier this year, according to Yahoo Tech. 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. We know, however, that attackers are constantly tweaking their techniques.

    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. Distributed denial-of-service (DDoS) attacks have been all over the news in recent months, with hacktivist groups taking major targets completely offline.
