Denial-of-service Attack - DOS using hping3 with spoofed IP in Kali Linux

Read full details here: Denial-of-service Attack - DOS using hping3 with spoofed IP in Kali Linux

In computing, a denial-of-service (DoS) or distributed denial-of-service (DDoS) attack is an attempt to make a machine or network resource unavailable to its intended users.

Although the means to carry out, the motives for, and targets of a DoS attack vary, it generally consists of efforts to temporarily or indefinitely interrupt or suspend services of a host connected to the Internet.

As clarification, distributed denial-of-service attacks are sent by two or more persons, or bots, and denial-of-service attacks are sent by one person or system. As of 2014, the frequency of recognized DDoS attacks had reached an average rate of 28 per hour.

Perpetrators of DoS attacks typically target sites or services hosted on high-profile web servers such as banks, credit card payment gateways, and even root nameservers.

Denial-of-service threats are also common in business, and are sometimes responsible for website attacks.

This technique has now seen extensive use in certain games, used by server owners, or disgruntled competitors on games, such as popular Minecraft servers. Increasingly, DoS attacks have also been used as a form of resistance. Richard Stallman has stated that DoS is a form of ‘Internet Street Protests’. The term is generally used relating to computer networks, but is not limited to this field; for example, it is also used in reference to CPU resource management.

One common method of attack involves saturating the target machine with external communications requests, so much so that it cannot respond to legitimate traffic, or responds so slowly as to be rendered essentially unavailable. Such attacks usually lead to a server overload. In general terms, DoS attacks are implemented by either forcing the targeted computer(s) to reset, or consuming its resources so that it can no longer provide its intended service or obstructing the communication media between the intended users and the victim so that they can no longer communicate adequately.

Denial-of-service attacks are considered violations of the Internet Architecture Board’s Internet proper use policy, and also violate the acceptable use policies of virtually all Internet service providers. They also commonly constitute violations of the laws of individual nations.
I recently published another post that shows you DOS attack map in Realtime. So if you got a good connection and enough bandwidth, hey, you might even see your own attack on that map.

Our take on Denial-of-service Attack – DOS using hping3

Let’s face it, you installed Kali Linux to learn how to DOS, how to crack into your neighbors Wireless router, how to hack into a remote Windows machine be that a Windows 2008 R2 server or Windows 7 or learn how to hack a website using SQL Injection. There’s lot’s of guide that explain it all. In this guide, I am about to demonstrate how to DOS using hping3 with random source IP on Kali Linux. That means,
  1. You are executing a Denial of Service attack or DOS using hping3
  2. You are hiding your a$$ (I meant your source IP address).
  3. Your destination machine will see source from random source IP addresses than yours (IP masquerading)
  4. Your destination machine will get overwhelmed within 5 minutes and stop responding.


Sounds good? I bet it does. But before we go and start using hping3, let’s just go over the basics..



What’s hping3?

hping3 is a free packet generator and analyzer for the TCP/IP protocol. Hping is one of the de-facto tools for security auditing and testing of firewalls and networks, and was used to exploit the Idle Scan scanning technique now implemented in the Nmap port scanner. The new version of hping, hping3, is scriptable using the Tcl language and implements an engine for string based, human readable description of TCP/IP packets, so that the programmer can write scripts related to low level TCP/IP packet manipulation and analysis in a very short time.
Like most tools used in computer security, hping3 is useful to security experts, but there are a lot of applications related to network testing and system administration.

hping3 should be used to…

  • Traceroute/ping/probe hosts behind a firewall that blocks attempts using the standard utilities.
  • Perform the idle scan (now implemented in nmap with an easy user interface).
  • Test firewalling rules.
  • Test IDSes.
  • Exploit known vulnerabilties of TCP/IP stacks.
  • Networking research.
  • Learn TCP/IP (hping was used in networking courses AFAIK).
  • Write real applications related to TCP/IP testing and security.
  • Automated firewalling tests.
  • Proof of concept exploits.
  • Networking and security research when there is the need to emulate complex TCP/IP behaviour.
  • Prototype IDS systems.
  • Simple to use networking utilities with Tk interface.
hping3 is pre-installed on Kali Linux like many other tools. It is quite useful and I will demonstrate it’s usage soon.

That’s enough background, I am moving to the attack. You only need to run a single line command as shown below:
