XSS Attacks Explained:

🔍 What is an XSS Attack?

Cross-Site Scripting (XSS) is one of the most common web application vulnerabilities. It happens when attackers inject malicious scripts into trusted websites.

When a user visits the infected page, their browser executes the malicious script. This can lead to:
✅ Stealing cookies and session tokens
✅ Redirecting users to fake websites
✅ Stealing login details
✅ Modifying web content

⚡ Types of XSS Attacks

1. Stored XSS (Persistent):

The malicious script is permanently stored on the target server (in database, comment box, forums). Every user visiting the page is exposed.

2. Reflected XSS:

The script comes from the user’s request (URL or form input) and is reflected back by the server.

3. DOM-based XSS:

The vulnerability exists in the client-side code (JavaScript). Data from the client is directly executed without proper sanitization.

🛠️ Tools Used in XSS Attacks

Hackers and ethical hackers use various tools to test and exploit XSS vulnerabilities:

1. Burp Suite – Used for intercepting requests and injecting payloads.
Command:

2. OWASP ZAP – Open-source tool for automated scanning of XSS vulnerabilities.

3. XSSer – A penetration testing tool to detect and exploit XSS.

4. BeEF (Browser Exploitation Framework): Used to exploit XSS vulnerabilities to control browsers.
