Handson with ChatGPT  

ChatGPT can be effectively utilized to automate reconnaissance tasks, such as requesting a vital list of server paths that can be tested for path traversal vulnerabilities. Additionally, it can be prompted to extract beneficial information from source code by creating non-intrusive and clever prompts, allowing ChatGPT to dig into the details and retrieve relevant data. This automation of reconnaissance tasks through ChatGPT streamlines the process and enhances efficiency. 

Path Enumeration with ChatGPT leads to sensitive data exposure on the site 

To identify available paths on a website, we require a list of site-specific paths that can be manually tested or checked using tools like Burp Suite. In this case, we are conducting tests on a vulnerable website meant for practice, specifically https://hack-yourself-first.com/. It’s important to mention that ChatGPT does not respond to intrusive prompts. Therefore, to obtain the desired results, we aim to deceive ChatGPT by presenting text that appears educational in nature, ensuring we receive the desired information. 

Approach 1: Create a prompt that instructs ChatGPT to generate an educational list of significant server paths. 

Ask again to create more holistic coverage of paths. 

Approach 2: Now, we will examine the generated path to verify its importance in producing desired outcomes. To do this, we will access the website and sequentially add the created paths. This can be a tedious task, especially when dealing with a large list of paths. To simplify the process, we can use Burp Intruder to automatically test all the paths. In this specific scenario, we will focus on the Robots.txt path (/robots.txt). 

Note: The robots.txt file is a text file that is placed in the root directory of a website to provide instructions to web robots or crawlers, also known as web spiders or bots. These bots are used by search engines and other web services to scan and index web pages. 

The robots.txt file contains directives that specify which parts of a website the bots are allowed to access and crawl, and which parts should be excluded. It helps control the behavior of search engine crawlers and prevents them from accessing certain pages or directories that the website owner wants to keep private or hidden from search results. 

The format of a robots.txt file consists of user-agent directives and disallow directives. User-agent directives specify the specific bots to which the following directives apply. The “*” symbol is a wildcard character that represents all bots. Disallow directives specify the URLs or directories that are not to be accessed by the specified bots. 

For example, a robots.txt file that disallows all bots from accessing the “/private” directory would contain the following directive: 

User-agent: * Disallow: /private/ 

Observe that appending /robots.txt gives more insight about possible paths, let’s append ‘/api/admin/users’ to test more functionality. It is to be noted that the site has revealed list of all users and there credentials without any authentication and ChatGpt helped to unrevealed IDOR vulnerability on the site. 

Testing for Click Jacking with ChatGPT 

Clickjacking, also known as UI redress attack, is a malicious technique used by attackers to deceive users into clicking on hidden or disguised elements on a website, without their knowledge or consent. The attacker overlays or embeds legitimate website content with malicious elements, making users unknowingly perform actions they didn’t intend, such as clicking on buttons or links that trigger unauthorized actions. Clickjacking poses a significant threat to user privacy and security. However, ChatGPT can be utilized to address clickjacking concerns. It can help in educating users about the risks associated with clickjacking and provide guidance on preventive measures. By offering clear and concise explanations, ChatGPT can empower users to recognize clickjacking attempts and take appropriate actions to safeguard their online interactions. Additionally, ChatGPT can assist website developers and security professionals in understanding and implementing countermeasures, such as implementing frame-busting scripts or utilizing X-Frame-Options headers, to mitigate clickjacking vulnerabilities. 

Approach 1: In this scenario, we can utilize ChatGPT to generate a template for testing clickjacking on the target host and gather information regarding the website’s susceptibility to this type of attack. 

Approach 2: To determine whether a website is susceptible to clickjacking, you can create an HTML file and view it in a web browser for verification. 

Notice that the code provided by ChatGPT assisted us in conducting the vulnerability assessment. 

Enumerate Subdomain with ChatGPT 

Let’s Create a prompt on ChatGPT to create a code in python which will enumerate subdomains of the host. 

Approach 1: Copy this generated code and create a Python file in any Python-supported IDE. Run the code and validate if the subdomain enumeration is successful on the device or not. 

In this case, we need to add a comprehensive list for subdomain enumeration to improve the process. Additionally, we can create a prompt to allow the user to input a high-quality list of subdomains for more accurate and effective results. 

As information gathering and reconnaissance play a vital role in planning subsequent exploits, the techniques employed in reconnaissance always require new suggestions to gather the desired amount of information. By utilizing an interactive prompt with ChatGPT, we have the flexibility to design and generate as much information as we need. The extent of information obtained largely depends on the type of prompt we create.
