Kali Linux man in the middle attack tutorial with Ettercap

Welcome again, you have read my previous post-Arp poisoning attack with ettercap tutorial in Kali Linux and you got suspense. And didn’t get full tutorial. In this article, we will cover  Kali Linux man in the middle attack tutorial and discuss every step. I hope you liked my notes on Penetration Testing Tutorial So enjoy this Article and leave a comment on it and don’t forget to help me by sharing this article.

arp table on Attacker

Step 1: On the Kali Linux ettercap is installed by default, To open it, Go into

Application >  Sniffing & Spoofing > ettercap-graphical

run ettercap on Kali Linux

Step 2: Go Next Sniff > Unified Sniffing OR Pres Shift+U

26 unidifiend 2

Another window will be pop up where you need to select Network interface from the drop-down menu and click next

26 network interface 3

Next, Go to Hosts > Scan for hosts

26 scan for hosts

In this option, Atacker system will scan the whole network and find out, “how many devices are connected to the network?”

Next step, To See the connected hosts in the network

Go Hosts > Host list or Press Key H

26 host and host list

Next tab will appear, In this menu you should select the desired host and click on add to target 1, afterward select another host and click on add to target 2

26 add target

Next, Go into Mitm > Arp poisoning after click on this option new window will be pop up check sniff remote connection and it OK. arp poisoning will start automatic

26 enable arp poisioning

Now you can sniff data by click on Start > Start Sniffing or Ctrl+W

26 start sniffing

When you finished all process, then sniffing will be started. If you want to check arp poisoning is activated or not Go Plugins > Manage the plugins OR Ctrl+P

And click on chk_poison You will see a result like the following image.

26 check poisoningWhen user will access any page and enter the login credential, It will be captured by attacker machine see result.

26 captured data

 

Note:  It will capture data over HTTP only if you want to capture data use sslstrip for mare detailSecure Socket Layer SSL analysis with sslstrip in Kali Linux

What is ARP?

ARP stand for Address Resolution Protocol It works on network layer and used to resolve IP Address into a MAC Address (physical Address). When a new computer or device is connected in the network it broadcast its MAC Address over the TCP/IP network, then all the connected devices find the MAC address of new machine and make the entry into the ARP table. It also request to obtain the MAC address and IP address of connected devices in network by broadcasting and When it gets the reply from the connected devices with IP and MAC it create a ARP table and make the entry of IP address and MAC address of connected devices.

To see the available arp table in your PC run the following command in command line prompt

arp -a

 

arp table on Attacker

This command will work both Linux and Window systems.

ARP Poisoning Attack:

ARP poisoning is type of attack in which Attacker changes the MAC address on victim’s ARP table. Attacker sends request and reply with forged packets to the victim, victim think these packets come from destination and can’t identify the forged packets and it make entry of forged MAC into his ARP table. As result victim sends packets to the attacker machine instead of real machine because, Now Victim works according its ARP table where destination MAC address is replaced by Attacker’s MAC.

ARP poisoning attack is very effective over the network, wired or wireless. By the help of this attack, Attacker can steal very sensitive information like username, password and credit card information.

Ettercap Tutorial

Ettercap is a comprehensive suite for man in the middle attacks. It features sniffing of live connections, content filtering on the fly and many other interesting tricks. It supports active and passive dissection of many protocols and includes many features for network and host analysis.

Launch Ettercap In Kali Linux

Step 1: Run Kali Linux

Step 2: Go to Application > Sniffing and Spoofing > Ettercap-graphical

run ettercap on Kali Linux

Using Wireshark filter ip address and port inside network

Hello friends, I am glad you here and reading my post on Using wireshark filter ip address. In this I will cover about sniffing, wireshark, it’s features, capturing data by wireshark filter ip address and port. First we discuss about Senario.

Scenario:

If your PC inside network or using wifi in your laptop, mobile, and other devices. If you open the any site and enter the login credential username and password. This username and password is transmit over the network and same if you enter the credit card information, also travel over the network. If someone called hacker can capture this credential then assume what will be happened? And it is possible by sniffing let’s see how!

What is Sniffing?

Sniffing is the process to monitor and capture the data travel over the network. This process commonly used by Network Administrator or Security auditor to find out the issue in the network and malicious activity inside network. Some Bad guy called hacker used this process to capture important credential like Username, password and credit card information. Once the information is captured hacker can get access without any problem. All this is happened by network sniffer tools like wireshark tcpdump etc.

Definition of Wireshark:

Wireshark is a network packet analyzer. A network packet analyzer will try to capture network packets and tries to display that packet data as detailed as possible.

You could think of a network packet analyser as a measuring device used to examine what’s going on inside a network cable, just like a voltmeter is used by an electrician to examine what’s going on inside an electric cable (but at a higher level, of course).

Wireshark is perhaps one of the best open source packet analysers available today.

Some intended purposes of Wireshark

Here are some examples people use Wireshark for:

  • Network administrators use it to troubleshoot network problems
  • Network security engineers use it to examine security problems
  • Developers use it to debug protocol implementations
  • People use it to learn network protocolinternals

Using wireshark Features

The following are some of the many features Wireshark provides:

  • Available forUNIX and Windows.
  • Capturelive packet data from a network interface.
  • Openfiles containing packet data captured with tcpdump/WinDump, Wireshark, and a number of other packet capture programs.
  • Importpackets from text files containing hex dumps of packet data.
  • Display packets withvery detailed protocol information.
  • Savepacket data captured.
  • Exportsome or all packets in a number of capture file formats.
  • Filter packetson many criteria.
  • Searchfor packets on many criteria.
  • Colorizepacket display based on filters.
  • Create variousstatistics.

Open Wireshark in Kali Linux: In Kali Linux wireshark exist under Application > Kali Linux > Top 10 Security Tools > Wireshark Or type following command on terminal and hit enter

$wireshark &

open wireshsark in kali linux

Capturing data in Wireshark:

After start wireshark you will find the list of available interface like eth0 or wireless etc. select the interface and click on start to start capturing process. As soon as you click one the start, you’ll see the packets start to appear in real time. Wireshark captures each packet sent to your system or from your system. If you’re capturing data over wireless interface and have enabled promiscuous mode, you’ll be able to see other’s system packets over the network.

selecet interface and start capturing

Stop the capturing: To stop the capturing, click on the cross sign over interface in red colour

Save captured data: for analyzing the traffic over the network later you need to save captured data into the file. Next, File > save, Give the location where you want to save and file name then click on the save. By default file saved in .pcapng format in wireshark version 1.10.2.

save file 1

Open saved file: To open the saved file go, File > Open or press Ctrl+O short key and browse saved file then open.

Capture only incoming and outgoing traffic on particular IP address 192.168.1.3

  • host == 192.168.1.3

Capture traffic to or from a range of IP addresses:

  • addr == 192.168.1.0/24

Capture traffic from a range of IP addresses:

  • src == 192.168.1.0/24

Capture traffic to a range of IP addresses:

  • dst == 192.168.1.0/24

Capture only DNS (port 53) traffic:

  • dns

Capture only Ethernet type EAPOL:

  • eapol

DNS and not particular IP address

  • (dns) && !(ip.dst == 192.168.1.4)

DNS and destination ip address

  • (dns) && (ip.dst == 192.168.1.4)

And more filters are available you can Visit for more detail
