this is presentation about Ettercap tool of Kali linux.

1. ETTERCAP
SLIDE NOW
Ettercap is a free, open-source
tool that can be used for man-in-
the-middle attacks on networks

2. About Ettercap :
Ettercap is a versatile tool used in
network security assessments and
penetration testing. It is commonly
used on Kali Linux, a popular
penetration
testing and ethical hacking platform
The most common uses for Ettercap
are man-in-the-middle attacks
through ARP poisoning. Additionally,
hackers use this tool, and you can use
it for penetration testing.

3. Ettercap provides various capabilities
that can help identify vulnerabilities and
enhance network security. Here are
some ways Ettercap is used in network
security:
Network Sniffing
Man-In-the-Middle-Attack
Protocol Analysis
Password sniffing
DNS spoofing
Ettercap is GUI based tool built into Kali so
need to download and install anything, so
let's get started doing a MiTM attack with
Ettercap.

4. Ettercap can capture and analyze
network packets,
allowing security professionals to
monitor and inspect network traffic.
This
helps in identifying potential security
issues such as unencrypted passwords,
sensitive data leakage, or malicious
activities
Network Sniffing

5. Ettercap can be used to conduct MITM attacks
to intercept and manipulate network
communication between a client and a server.
Between two hosts, enabling security
professionals to test the security of
applications and protocols.
The steps involved in a MITM attack with
Ettercap include :
a. Perform ARP spoofing to redirect traffic
through your machine.
b. Enable IP forwarding on your machine to
act as a router.
MITM

6. Password Sniffing: By intercepting network
traffic, Ettercap can capture login
credentials and passwords transmitted over
the network.
This can be useful in assessing the security of
authentication mechanisms and identifying
weak passwords
This allows for the identification of security
flaws that can be exploited by attackers

7. ARP Spoofing: Ettercap can conduct ARP
spoofing attacks, where it manipulates
the Address Resolution Protocol (ARP)
tables to redirect network traffic through
the attacker's machine.

This technique helps in intercepting
and inspecting network communications.

10. Step #1: Start ettercap

Let's view the help file for
ettercap by typing;
kali > ettercap -h
As you can see, ettercap has a
significant help file for running it
from a command line, but the only
thing we need from here is the
switch to run it in graphical mode. In
the bottom line of the screenshot
,you can see the -G switch. This will
launch the ettercap GUI.

11. Step #1: Start ettercap

When we do, the ettercap GUI
will start.
kali > ettercap -G.
The first step in launching our
MiTM attach is to start sniffing.
Go to pulldown menu that says
"Sniff" and click on "Unified
Sniffing".

12. Step #1: Start ettercap

When we do that, it opens a new
window asking us what interface
we want to use and defaults to
eth0.
When we click "OK", ettercap
launches it sniffing and loads its
plugins.
Our next step to find the hosts on
the network

13. Step #1: Start ettercap

Click on the "Hosts" tab and you
will see a menu that includes
"Scan for Hosts". Click on it and
ettercap will begin scanning the
network for hosts.
Now, using that same "Hosts" tab,
click on "Hosts List". This will
display all the hosts that ettercap
has discovered on your network as
seen in the screenshot below

14. Step #1: Start ettercap

Now, select one of the hosts that
will be the target of this attack in
the window by clicking on it and
then click on "Add to Target 1" at
the bottom of the window.
When you do so, ettercap will add
that host as the first target in our
MiTM attack as seen in the
screenshot below.
Next, select the second host in this
attack and then click "Add to
Target 2".

15. Step #1: Start ettercap

Finally, go to the menu above and click on MITM
tab and the drop down menu will have a
selection called "ARP Poisoning" as seen in the
screenshot below.
Select it and it will open a pop window like below.
Select "Sniff remote connections".
When we press OK, ettercap will begin ARP
poisoning and you will see ettercap respond in its
main windows with the message below.

16. Altering the Traffic

Now, we have successfully placed ourselves between the two targets systems and all
their traffic must flow through us. This is where the fun begins as we can now delete,
manipulate, impersonate and view all their traffic.??????
As I mentioned above, the real risk in a MiTM attack is that the attacker can eavesdrop
on the Internet traffic as well as alter it, if they want. In this section, now that we are
between the two systems we will demonstrate the risks of MiTM attack. We will use the
MiTM attack to edit/alter the Internet traffic as seen by the target. In this way, the
attacker can actually alter the content of websites, alter the content of an email, change
the pictures seen by the target in their Internet traffic, delete specific Internet traffic
packets, etc. The message should be clear, when we have placed ourselves in the
middle, the target is at our mercy!
