How to amplify an AirPuffin attack with DNS spoofing?
In the fascinating and challenging world of computer security, one of the most critical aspects is to understand how certain attacks can be conducted to effectively protect ourselves. This article delves into how to extend an AirPuffin attack by implementing DNS spoofing attacks. Get ready to delve into advanced traffic infiltration and redirection techniques as we explain the methodology and steps involved in this process.
What is and how do I set up an attack environment in Kali Linux?
To begin with, it is vital to set up a controlled environment where you can safely execute attacks. Using Kali Linux, you are going to simulate a Man-in-the-Middle attack with a tool known as ettercap:
-
Configure ettercap:
- Start ettercap with the
Unified option to use a single interface:ettercap -at eth0
.
- Stop conflicting processes before starting capture with
ettercap --silent.
-
Host scan:
- Perform a scan to identify the IP addresses of devices present on the network segment.
- Assign the target IP address as target 1 and the gateway IP as target 2.
-
Initiate ARP attack:
- Launch the ARP spoofing attack to intercept traffic between the client and the server.
How to configure a DNS spoof attack?
Once you have successfully intercepted the traffic, it is time to configure the DNS spoof attack, which will allow you to redirect the domains requested by the victim to IP addresses of your choice.
-
Edit ettercap configuration files:
-
Configuration of permissions and privileges:
- Verify that in the
etter.conf file, the ec_uid and ec_gid values are set to zero to allow ettercap to run with administrator privileges:ec_uid = 0ec_gid = 0.
-
Traffic redirection:
- Enable traffic redirection so that traffic to the spoofed domain is answered by your own server in Kali Linux.
How to verify and adjust the spoofing operation?
To confirm that the attack is running successfully, a couple of additional actions and checks can be performed:
-
Execute DNS queries from the victim machine:
-
Start an Apache web server:
-
Modify the web content:
- Edit the default page to reflect the fake content you want to display to the user.
What can we learn and how to practice more?
The success of these attack tactics underscores the vital importance of computer security. To further deepen and practice, Platzi offers various courses in HTML, CSS, web design and Linux server administration. This will help you get better at not only building better fake web pages, but also at understanding the broader network and server infrastructure.
In addition, an interesting challenge would be to experiment with translating domain names for different IP addresses and different services. This practice may reveal subtleties and variations in behavior depending on the domain and network environment.
