Using Search Engines
One of the easiest and fastest ways to find a vulnerable website is to use search engines like Google or Bing. Search engines index millions of websites and store information about their content, structure, and metadata. By using certain keywords or operators, you can filter the search results and find websites that match your criteria.
For example, you can use the following keywords or operators to find websites that use a specific technology, platform, or software that may have known vulnerabilities:
inurl: - This operator searches for websites that have a specific word or phrase in their URL. For example, inurl:php?id= will find websites that use PHP and have a parameter named id in their URL. This parameter may be vulnerable to SQL injection attacks.
intitle: - This operator searches for websites that have a specific word or phrase in their title. For example, intitle:"index of /" will find websites that have a directory listing enabled. This may expose sensitive files or directories.
intext: - This operator searches for websites that have a specific word or phrase in their text content. For example, intext:"powered by WordPress" will find websites that use WordPress as their content management system. WordPress may have vulnerabilities in its core, plugins, or themes.
filetype: - This operator searches for websites that have a specific file type or extension. For example, filetype:sql will find websites that have SQL files. These files may contain database credentials or queries.
site: - This operator searches for websites that belong to a specific domain or subdomain. For example, site:edu will find websites that have an edu domain. These websites may belong to educational institutions that have outdated or unsecured systems.
You can also combine these operators with other keywords or operators to narrow down your search results. For example, inurl:php?id= intext:"error" will find websites that use PHP, have an id parameter in their URL, and display an error message. This may indicate that the website is vulnerable to SQL injection attacks and has poor error handling.
Using Online Tools
If you want to automate the process of finding a vulnerable website, you can use online tools that scan and analyze websites for vulnerabilities. There are many online tools available for free or for a fee that offer different features and functionalities. Some of the most popular and reliable ones are:
[Shodan] - Shodan is a search engine that lets you find devices connected to the internet, such as web servers, routers, cameras, printers, etc. You can use Shodan to find devices that have open ports, services, protocols, banners, or vulnerabilities. You can also filter the results by location, operating system, product, version, etc.
[Nmap] - Nmap is a network scanner that lets you discover hosts and services on a network. You can use Nmap to scan a website's IP address or domain name and find out what ports are open, what services are running, what operating system is used, what firewall rules are applied, etc. You can also use Nmap scripts to perform more advanced scans and tests for vulnerabilities.
[Nikto] - Nikto is a web server scanner that lets you test a website for various vulnerabilities and misconfigurations. You can use Nikto to check for outdated software versions, insecure files or directories, default passwords, server-side scripts, cross-site scripting (XSS) attacks, etc.
[OWASP ZAP] - OWASP ZAP is a web application scanner that lets you test a website for common web application vulnerabilities and security issues. You can use OWASP ZAP to perform active or passive scans, spider or crawl a website, intercept or modify requests or responses, test for SQL injection, XSS, CSRF, etc.
Using Manual Techniques
If you want to have more control and flexibility over finding a vulnerable website, you can use manual techniques that involve using your own tools, skills, and creativity. Manual techniques can be more challenging and time-consuming, but they can also be more rewarding and fun. Some of the manual techniques you can use are:
Using a proxy tool - A proxy tool is a tool that acts as an intermediary between your browser and the website you are visiting. You can use a proxy tool to monitor, capture, modify, or replay the requests and responses between your browser and the website. This can help you analyze the website's behavior, functionality, and logic, and find potential vulnerabilities or flaws. Some of the most popular proxy tools are [Burp Suite], [Fiddler], and [Charles].
Using a code editor - A code editor is a tool that lets you write, edit, or modify code. You can use a code editor to view or edit the source code of a website, or to create your own scripts or payloads to test the website for vulnerabilities. Some of the most popular code editors are [Visual Studio Code], [Sublime Text], and [Atom].
Using a browser extension - A browser extension is a tool that adds extra features or functionalities to your browser. You can use a browser extension to enhance your browsing experience, or to perform various tasks or tests on a website. Some of the most popular browser extensions for finding vulnerabilities are [Wappalyzer], [Web Developer], and [Tampermonkey].
Conclusion
Finding a vulnerable website can be an interesting and useful activity for various purposes. However, it is important to remember that hacking or exploiting a vulnerable website without permission is illegal and unethical. You should only test websites that you own or have permission to test, or use websites that are designed for learning or practicing hacking skills, such as [Hack The Box], [VulnHub], or [OWASP Juice Shop]. Happy hacking!
