Why Every Tech Professional Needs to Learn Basic Cyber Hygiene in 2025 | Secure Your Career in a Threat-Filled Digital World

In the evolving landscape of cybersecurity, Cross Site Scripting (XSS) remains one of the most common and dangerous vulnerabilities found in web applications. Despite being well-documented and well-known, XSS continues to pose serious risks for websites, organizations, and users across the globe.

In this blog, we’ll break down:

• What XSS is

  
  

• How it works

• Real-world consequences

• Types of XSS

• How to protect against it

✅ What is Cross Site Scripting (XSS)?

Cross Site Scripting (XSS) is a web security vulnerability that allows attackers to inject malicious scripts into webpages viewed by other users. These scripts run in the context of the victim's browser, enabling attackers to steal data, hijack sessions, or perform actions on behalf of the user without their consent.

In simple terms: XSS tricks a user’s browser into trusting and running malicious code on a legitimate website.

How XSS Works: Step-by-Step Breakdown

The process typically involves four key steps:

1. Attacker sends a malicious link containing an embedded script to a user (via email, message, etc.)

2. Victim clicks the link and unknowingly lands on a legitimate site.

3. The legitimate site loads in the victim’s browser, but the attacker’s script executes alongside.

4. Malicious script runs, sending sensitive data like session cookies back to the attacker.

Why XSS is Dangerous

• Account compromise

• Session hijacking

• Unauthorized actions on behalf of users

• Data theft

• Phishing

• Spreading malware

• Damaging brand trust

Types of XSS Explained

 1. Reflected XSS

• Payload is not stored on the server.

• Executed immediately after user input.

• Common in URLs or form submissions.

• Example: Injected JavaScript in a search query that’s returned unsanitized.

Think: One-time attack delivered directly to the victim.

 2. Stored XSS

• Payload is persistently stored in the database.

• Triggers each time the page loads.

• More dangerous due to wide reach and repeated activation.

• Example: A script in a forum post or comment section.

Think: Long-lasting, widespread infection vector.

How to Prevent XSS Attacks

Tools to Detect and Test XSS

• Burp Suite – Popular tool for scanning and exploiting XSS.

• OWASP ZAP – Open-source web application scanner.

• XSSer – Automated XSS vulnerability detection tool.

• Google Chrome DevTools – Great for testing scripts and DOM behavior.

Real-World XSS Attacks

• eBay XSS Exploits: Attackers embedded malicious JavaScript in listings.

• Twitter (past) and MySpace were also victims of stored XSS during their early days.

• Countless browser extensions have been compromised using XSS vulnerabilities.

Conclusion

XSS remains a serious threat due to its simplicity and powerful consequences. Understanding how it works and how to prevent it is essential for:

• Web developers

• Security researchers

• QA testers

• And even regular users

Organizations must proactively audit their websites and apps to ensure user input is never blindly trusted or echoed back.
