Bug Hunting Methodology: A Comprehensive Guide

Bug hunting is a critical skill for cybersecurity professionals, enabling them to identify vulnerabilities before malicious actors exploit them. Below is a detailed methodology, along with practical commands, tools, and steps to enhance your bug-hunting skills.

Bug Hunting Methodology

1. Reconnaissance

• Gather information about the target (subdomains, IP ranges, technologies).
• Tools:

  subfinder -d example.com -o subdomains.txt 
  amass enum -d example.com -o amass_results.txt 
  nmap -sV -p- target.com -oN nmap_scan.txt 
  

2. Vulnerability Scanning

• Use automated scanners to detect common vulnerabilities.
• Tools:

  nuclei -u https://target.com -t ~/nuclei-templates/ 
  nikto -h target.com -output nikto_scan.txt 
  

3. Manual Testing

• Test for OWASP Top 10 vulnerabilities (SQLi, XSS, CSRF, etc.).
• Example SQLi test:

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

4. Exploitation

• Validate vulnerabilities by crafting exploits.
• Example (Metasploit):

  msfconsole 
  use exploit/multi/http/sql_injection 
  set RHOSTS target.com 
  exploit 
  

5. Reporting

• Document findings with PoC (Proof of Concept).
• Tools:

  cutycapt --url=https://target.com --out=report.png 
  

You Should Know:

• Essential Linux Commands for Bug Hunting:

  grep "pattern" file.txt  Search for patterns 
  curl -X POST "https://target.com/login" -d "user=admin&pass=test" 
  wfuzz -c -z file,wordlist.txt -d "param=FUZZ" https://target.com 
  

• Windows Commands for Security Testing:

  nslookup target.com 
  netstat -ano  Check open ports 
  certutil -urlcache -split -f http://example.com/file.exe 
  

• Nuclei Templates for Automated Scanning:

  nuclei -update-templates 
  nuclei -l targets.txt -t cves/ -o nuclei_results.txt 
  

What Undercode Say:

Bug hunting requires persistence, creativity, and a structured approach. Always stay updated with new vulnerabilities and tools. Practice in legal environments like Hack The Box or Bugcrowd. Mastering manual testing alongside automation will make you a formidable security researcher.

Expected Output:

• Subdomain enumeration results (subfinder, amass).
• Vulnerability scan reports (nuclei, nikto).
• Exploitation proof (sqlmap, metasploit).
• Professional report with screenshots (cutycapt).
