I Built a Free eJPT Preparation Guide — Roadmap, Notes, Commands & Labs

If you're preparing for the eJPT (Junior Penetration Tester) certification, one of the hardest parts isn't finding information.

It's finding the right information in the right order.

I recently organized my eJPT preparation and penetration-testing revision material into a free, open-source GitHub repository:

👉 https://github.com/saivishwaa/eJPT-Prep-Guide

The main idea behind the repository is:

Recon
  ↓
Scan
  ↓
Enumerate
  ↓
Identify
  ↓
Exploit
  ↓
Escalate
  ↓
Pivot
  ↓
Document

Instead of treating penetration testing as a list of commands to memorize, the guide is structured around this methodology.

📚 What's inside?

1. Networking & Reconnaissance

Network fundamentals
DNS enumeration
Passive reconnaissance
Active reconnaissance
Subdomain enumeration
Host discovery
Useful reconnaissance commands

2. Nmap

Practical Nmap references for:

Host discovery
TCP scanning
UDP scanning
Full port scans
Service detection
OS detection
NSE
Vulnerability scanning
Output parsing

3. Service Enumeration

References for common services including:

SMB
FTP
SSH
HTTP/HTTPS
MySQL
SMTP
RPC
LDAP
RDP
WinRM

The goal is to understand what information each service can expose and how to enumerate it systematically.

🔥 Vulnerability Assessment

The guide covers:

Nmap vulnerability scripts
SearchSploit
ExploitDB
Manual verification
Windows checks
Linux checks
Web vulnerability testing
Kernel exploit research

There's also a basic vulnerability-reporting structure for documenting findings.

💥 Exploitation

The exploitation section includes practical references for:

Metasploit
MSFVenom
Reverse shells
Multi/Handler
Shell upgrades
File transfers
Common exploitation workflows

🪟 Windows Privilege Escalation

Topics include:

systeminfo
whoami /all
Services
Unquoted service paths
Weak service permissions
AlwaysInstallElevated
Token impersonation
Registry checks
Credential discovery
Scheduled tasks
WinPEAS

🐧 Linux Privilege Escalation

The Linux section covers:

sudo -l
SUID/SGID
Linux capabilities
Cron jobs
NFS
Credential/key hunting
Kernel vulnerabilities
LinPEAS
Linux Exploit Suggester
LSE
pspy

GTFOBins is also included as a reference for researching potentially exploitable binaries.

🌐 Web Application Testing

The web-testing section contains references for:

Directory enumeration
SQL injection
XSS
Authentication testing
Directory traversal
LFI
File upload testing
Command injection
SSRF
SQLMap
Gobuster
ffuf
WhatWeb

🔀 Post-Exploitation & Pivoting

The guide also includes references for:

Meterpreter
Credential access
Port forwarding
SSH tunneling
SOCKS proxies
Chisel
Lateral movement

🗺️ Recommended Learning Path

If you're completely new to penetration testing, I'd approach the material in this order:

Networking
    ↓
Linux Fundamentals
    ↓
Reconnaissance
    ↓
Nmap
    ↓
Service Enumeration
    ↓
Vulnerability Assessment
    ↓
Exploitation
    ↓
Linux Privilege Escalation
    ↓
Windows Privilege Escalation
    ↓
Web Application Testing
    ↓
Post-Exploitation
    ↓
Pivoting
    ↓
Practical Labs
    ↓
Exam Preparation

The important part is hands-on practice.

Reading commands is not enough.

Try to understand:

What information am I looking for?

Why am I running this command?

What does the output tell me?

What should I investigate next?

That mindset is what turns a command reference into an actual methodology.

🧪 Practice > Memorization

A useful learning loop is:

Learn
 ↓
Understand
 ↓
Practice
 ↓
Troubleshoot
 ↓
Document
 ↓
Repeat

Practice the material only in authorized labs, CTFs, intentionally vulnerable systems or environments where you have permission to test.

⭐ Open Source

The complete guide is available here:

👉 https://github.com/saivishwaa/eJPT-Prep-Guide

If you're preparing for eJPT, feel free to:

⭐ Star the repository
🍴 Fork it
📢 Share it with other learners
💡 Open issues for corrections
🤝 Contribute additional resources

I'm continuing to improve the repository and add useful material over time.

Final Thoughts

There are plenty of cybersecurity resources available online.

The difficult part is often connecting them together.

That's what I wanted this repository to help with.

A single place to revise:

Recon → Nmap → Enumeration → Vulnerability Assessment → Exploitation → Privilege Escalation → Web Testing → Pivoting → Documentation

If you're preparing for the eJPT, I hope this helps you spend less time searching for resources and more time actually practicing.

Learn the methodology. Practice ethically. Document everything.
