Introduction

Session hijacking is defined as taking over an active TCP/IP communication session without the user’s permission. When implemented successfully, attackers assume the identity of the compromised user, enjoying the same access to resources as the compromised user. Identity theft, Information theft, stealing sensitive data are some of the common impacts of session hijacking.

Types of session hijacking attacks:

There are two types of session hijacking depending on how they are done. If the attacker directly gets involved with the target, it is called active hijacking, and if an attacker just passively monitors the traffic, it is passive hijacking.

Active:

The attacker will silence one of the machines, usually the client computer, and take over the clients’ position in the communication exchange between the workstation and the server. The active attack also allows the attacker to issue commands on the network making it possible to create new user accounts on the network, which can later be used to gain access to the network without having to perform the session hijack attack.

The Ethical Hacker training course is a generalized training course for information security professionals. This training course provides the students with an overview of the tools, techniques, and skills required to become a successful and effective ethical hacker. The goal of this course is to help the candidates master an ethical hacking. They teach topics like Network Scanning, Enumeration, Session Hijacking, Kali Linux, Footprinting, and much more.

Passive:

In Passive session hijacking attack, the attacker monitors the traffic between the workstation and server. The primary motivation for the passive attack is to monitor network traffic and potentially discover valuable data or passwords.

Man-in-the-middle Attack

We will start session hijacking with man-in-the-middle and start capturing packets. Here our attacker machine is Kali Linux and the victim is a Windows 10 virtual machine. First we will make sure that IPv4 is set to 1. To do this use command –

nano /proc/sys/net/ipv4/ip_forward

This will open a file. In this change the entry from 0 to 1. We will start spoofing with the command

arpspoof -i eth0 -t 192.168.1.104 192.168.1.1

We can get the target IP address by doing ipconfig on the target machine. Now we will do just the reverse in another window.

Session

arpspoof -i eth0 -t 192.168.1.1 192.168.1.104

Now the spoofing attack is under way.

Wireshark Sniffing

Open Wireshark on the Kali machine. For this demo we have installed an application called DVWA( Damn Vulnerable Web App) on the Windows 10 virtual machine. it is a great tool when practising vulnerable web applications. Its home page will look like this –

Figure1. Wireshark(Left-Kali Machine), DVWA (Right-Windows10)

Start capturing packets on Wireshark. Login with username and password in DVWA. Go to DVWA security, set the security level from impossible to low. Now we have captured the packets. Look at the cookies of this side by going into Chrome->More Tools->Developer Tools. Under application we can see cookies. There is the site with the session ID and security.

Figure2. Cookies

We will see if we have captured it on Wireshark also. We will stop capturing packets. Go to File->Save As… and save the actually captured file with .pcap extension on desktop.

We are going to use another tool called ‘Network Miner’ to actually look at the traffic. It takes a capture file and makes it readable. We can download the free version from Network Miner site. Follow the steps to install it on Kali Linux machine. It gets installed in opt directory. After installing, open terminal and cd into the Network Miner directory. Enter the command –

mono NetworkMiner.exe

Network Miner window will open. Go to File->Open and open the capture.pcap file. It will parse it and give all the information including IP addresses, files, messages, credentials, etc. We will go to the credentials tab.

Figure3. Credentials

We can clearly see, that the Session ID has changed to security low. This is the session ID we need. We will copy it, paste it temporarily in a text document. We can see that they are two cookies and are exactly same as in DVWA.

Hijacking the Session

Open Firefox and open DVWA on kali machine also. We have a small Firefox plugin called ‘Cookie Manager Advanced’. Open that plugin and we can see some past cookies in it. We will delete all cookies from all domains. Now close it and reload the DVWA page. Open Cookie Manager Advanced again and click on the current session ID. Now we will change the Session ID to same as on the Windows 10 machine which we have copied on a text document. Also set the security to low and save it. Go to the same url i.e. 45.55.133.158/security.php. Now we have exactly the same access as we had on Windows machine.
