How to Hunt Bugs and Secure Web Applications Like a Pro

Vulnerability PoCs: https://lnkd.in/gwvPV3-M

Bug bounty hunting and vulnerability assessment are critical skills in cybersecurity. Security researchers like Parth Narula identify flaws in web applications, report them, and help organizations strengthen their defenses. Below are key techniques, commands, and tools used in bug hunting and penetration testing.

You Should Know:

1. Reconnaissance & Enumeration

Before attacking, gather information about the target:

• Subdomain Enumeration:

  subfinder -d example.com -o subdomains.txt 
  amass enum -d example.com -o amass_results.txt 
  

• Port Scanning:

  nmap -sV -T4 -p- example.com -oN nmap_scan.txt 
  

• Web Directory Brute-Forcing:

  ffuf -w /path/to/wordlist -u https://example.com/FUZZ 
  

2. Vulnerability Scanning

Automated tools help identify common flaws:

• Nikto (Web Scanner):

  nikto -h https://example.com 
  

• Burp Suite:

Intercept and manipulate HTTP requests for testing.

3. Exploiting Common Web Vulnerabilities

• SQL Injection:

  sqlmap -u "https://example.com/login?id=1" --dbs 
  

• XSS (Cross-Site Scripting):

  <script>alert('XSS')</script> 
  

• CSRF (Cross-Site Request Forgery):
  Craft malicious requests to trick users into unwanted actions.

4. Post-Exploitation & Reporting

After finding a bug:

• Document steps to reproduce.
• Submit a Proof of Concept (PoC) via the organization’s VDP (Vulnerability Disclosure Program).

What Undercode Say:

Bug bounty hunting requires persistence, creativity, and deep knowledge of web security. Always follow responsible disclosure and avoid illegal hacking.

Expected Commands & Tools:

• Linux Commands:

  grep "vulnerable" logs.txt  Search for vulnerabilities in logs 
  chmod 600 sensitive_file  Secure file permissions 
  

• Windows Commands:

  netstat -ano  Check open ports 
  whoami /priv  Check user privileges 
  

• Automation Scripts:

  Bash script for auto-scanning 
  !/bin/bash 
  echo "Starting scan..." 
  nmap -sV $1 
  

Prediction:

As web applications grow, AI-powered bug hunting will rise, automating vulnerability detection. More companies will adopt bug bounty programs, increasing opportunities for ethical hackers.

Expected Output:

A structured guide on bug hunting techniques with practical commands and tools for security researchers.
