John Cruz’s transition from full-stack developer to Web Application Penetration Tester highlights the growing demand for cybersecurity expertise. His certifications—PWPA, PJPT, and PWPP—from TCM Security demonstrate hands-on skills in exploiting OWASP Top 10 vulnerabilities, Active Directory attacks, and API/web app pentesting. Below, we dive into practical tools and commands for aspiring testers.
You Should Know:
1. OWASP Top 10 Exploitation
- SQL Injection:
“`sqlmap -u “http://example.com/login?user=admin” –dbs“`
Use `–risk=3` and `–level=5` for deeper scans.
- XSS Testing:
“`“`
Test payloads in input fields or URLs.
2. Active Directory Exploitation
- Kerberoasting:
“`bash.py -dc-ip domain/user:password -request“`
- Pass-the-Hash:
“`bash-winexe -U admin% // cmd“`
3. Web App & API Pentesting
- Burp Suite: Intercept requests with `Proxy` tab.
- Nikto Scan:
“`nikto -h http://example.com“`
– API Fuzzing:
“`ffuf -u http://api.example.com/FUZZ -w wordlist.txt“`
4. Reporting with CVSS
- Calculate scores using:
“`bash://www.first.org/cvss/calculator/3.1“`
What Undercode Say:
Web app pentesting requires persistence. Start with OWASP ZAP, Nmap, and Metasploit. Practice on labs like Hack The Box or TryHackMe. For API security, master Postman and JWT exploits. Always document findings for clear stakeholder reports.
Expected Output:
- Tools: SQLMap, Burp Suite, Kerbrute, Responder.
- Commands:
“`nmap -sV -p- “` (Full port scan)
“`gobuster dir -u http://example.com -w /usr/share/wordlists/dirb/common.txt“`
