DNS Spoofing- Ettercap Backtrack5 Tutorial

DNS Spoofing attack

Spoofing attack is unlike sniffing attack, there is a little difference between spoofing and sniffing. Sniffing is an act to capture or view the incoming and outgoing packets from the network while spoofing is an act to forging one's source address. In spoofing attack an attacker make himself a source or desire address. This is basically done by using some tricks.

Spoofing is so general word and it contains attack like DNS spoofing, IP spoofing and others.

What Is DNS Spoofing?

DNS spoofing is an attack that can categorize under Man-In-The-Middle-Attack, beside DNS Spoofing MIMA contain:

• ARP poisoning
• Sessions hijacking
• SSL hijacking
• DNS Spoofing

Each attack has its own importance but to be sure it is very difficult to discuss all attacks in single article, I will post some more articles related to MIMA.DNS spoofing is an attack in which an attacker force victim to enter his credential into a fake website, the term fake does not mean that the website is a phishing page while. To understand DNS spoofing refer to this pictures.

In the normal communication a user send request to the real DNS server while if an attacker spoof the DNS server than this attack is called Man-In-The-Middle-Attack.

Now the question is how to perform DNS spoofing attack, the term spoofing is very similar with sniffing and the sniffing tools can used to perform spoofing attack. For this article I will use ettercap.

What Is Ettercap?

According to official website “Ettercap is a suite for man in the middle attacks on LAN. It features sniffing of live connections, content filtering on the fly and many other interesting tricks”.It is support cross operating system like it can run on Windows, Linux, BSD and MAC.

DNS Spoofing Tutorial With Ettercap-Backtrack5

If you want to learn more background theory than you can ask question by using comment box, now this section will teach you how to perform Spoofing (Man-In-The-Middle-Attack) attack.

Requirement:

• An Operating system (Linux, Windows etc).
• Ettercap.
• SET(Social Engineering Toolkit).

I am using backtrack 5 for this tutorial you can use some other OS, social engineering toolkit is not a necessary part but as discussed before about SET tutorial for hacking windows by using fake IP so you can use Spoof your IP into a website. So this is little advance tutorial.

Note : It is recommended to use DNS spoofing attack with Social Engineering Toolkit attack to make the job done effectively.
