Understanding Social Engineering Toolkit in Kali Linux: A Comprehensive Guide

The Social Engineering Toolkit (SET) is a powerful and versatile tool included in Kali Linux, designed specifically for social engineering attacks. It provides a range of features that allow cybersecurity professionals to simulate and understand how attackers exploit human behavior to gain unauthorized access to systems. This guide is intended for technical students and professionals who want to master SET for penetration testing and security assessments.

For those looking to deepen their knowledge and skills, consider enrolling in our Kali Linux in Cyber Security course at Indian Cyber Security Solutions.

1. Introduction to the Social Engineering Toolkit (SET)

SET was developed by TrustedSec and is designed to perform advanced attacks against the human element. Unlike traditional penetration testing tools, SET focuses on social engineering, where the goal is to trick individuals into revealing confidential information or performing actions that compromise security.

Key Features of SET:

• Phishing attacks
• Spear phishing
• Website attack vectors
• Credential harvesting
• USB-based attacks
• Wireless access point attacks
• Integration with Metasploit for advanced exploitation

2. Installing and Launching SET

Step 1: Verify SET Installation

SET comes pre-installed with Kali Linux, but you can verify its presence by using the following command:

locate setoolkit        

If it is not installed, you can install it using:

sudo apt-get install set        

Step 2: Launch SET

To start SET, open a terminal and run:

sudo setoolkit        

You will be greeted with the SET main menu, which provides access to various attack vectors.

3. Setting Up a Phishing Attack

Phishing is one of the most common social engineering techniques. With SET, you can clone websites and capture credentials from unsuspecting users.

Step 1: Choose Social-Engineering Attacks

From the main menu, select the option:

Social-Engineering Attacks        

Step 2: Select Website Attack Vectors

Next, choose:

Website Attack Vectors        

Step 3: Pick the Credential Harvester Attack Method

Choose the method that will allow you to capture credentials:

 Credential Harvester Attack Method        

Step 4: Select Site Cloner

Clone a legitimate website by selecting:

Site Cloner        

Step 5: Enter the URL to Clone

Input the URL of the site you want to clone. For example:

http:/example.com        

SET will create a local clone of the website, and when a user enters their credentials, they will be captured and stored by SET.

4. Conducting a Spear Phishing Attack

Spear phishing is a targeted version of phishing, where attackers tailor their attacks to specific individuals or organizations.

Step 1: Choose Spear-Phishing Attack Vectors

From the SET main menu, select:

 Spear-Phishing Attack Vectors        

Step 2: Select a Template

Use one of the pre-configured email templates or create your own. This template will be used to craft a convincing phishing email.

Step 3: Send Email with Malicious Attachment

Attach a malicious payload to the email. When the target opens the attachment, the payload will execute, potentially giving the attacker control over the target's system.

5. Using SET for USB-Based Attacks

Attackers can also use USB drives as a vector for delivering malicious payloads. SET makes it easy to create an infectious USB drive.

Step 1: Select Infectious Media Generator

From the SET main menu, choose:

Infectious Media Generator        

Step 2: Choose Payload and Listener

Select the payload that you want to deliver (e.g., a reverse shell) and configure the listener that will catch the incoming connection from the infected machine.

Step 3: Create the Infectious USB

Follow the prompts to create a USB drive that will execute the payload when inserted into a target computer.

6. Creating a Fake Wireless Access Point

One effective method of capturing credentials and other sensitive information is by creating a rogue wireless access point.

Step 1: Select Wireless Attack Vectors

From the SET main menu, choose:

Wireless Attack Vectors        

Step 2: Create a Fake Access Point

Set up a rogue access point that mimics a legitimate one. This can trick users into connecting to it, at which point you can capture their traffic.

Step 3: Monitor and Capture Traffic

Use SET’s built-in monitoring tools to capture and analyze the traffic from connected devices.

7. Generating Payloads with SET

SET also allows you to generate various types of payloads that can be used in different attack vectors.

Step 1: Select Payloads and Listeners

From the SET main menu, select:

Create a Payload and Listener        

Step 2: Choose a Payload

Select from a list of pre-configured payloads like reverse shells, meterpreter sessions, etc.

Step 3: Set Up the Listener

Configure the listener to receive incoming connections from compromised systems.

8. Social Engineering with SET and Metasploit

SET can be integrated with Metasploit, a powerful exploitation framework, to conduct advanced social engineering attacks.

Step 1: Integrate SET with Metasploit

From the SET main menu, select:

Third Party Modules        

Choose the Metasploit integration option to use Metasploit modules within SET.

Step 2: Conduct Advanced Attacks

Leverage Metasploit’s extensive library of exploits in conjunction with SET to perform sophisticated social engineering attacks.

9. Reporting and Analysis

After conducting social engineering attacks, it’s important to analyze the results and document the findings.

Step 1: Monitor Attack Results

SET provides real-time monitoring of attacks, including credentials harvested, payload execution, and more.

Step 2: Generate Reports

After the attack, generate detailed reports to analyze the effectiveness of the social engineering campaign.

Step 3: Implement Countermeasures

Based on the findings, recommend or implement security measures to mitigate the risks identified during the testing.

Conclusion

Understanding and utilizing the Social Engineering Toolkit in Kali Linux is essential for cybersecurity professionals who want to enhance their skills in social engineering attacks. By following this guide, you can learn how to use SET to conduct a variety of attacks and understand how attackers exploit human behavior.
