🔓 Attack Path Lab – From Reconnaissance to Privilege Escalation

📌 Overview

This project simulates a real-world penetration testing scenario in a controlled lab environment. The objective was to identify potential attack paths from initial reconnaissance to privilege escalation on a Linux server.

The lab demonstrates how exposed services, authentication weaknesses, and privilege misconfigurations can lead to full system compromise.

This project highlights both offensive security techniques and defensive awareness.

🎯 Objectives

• Perform reconnaissance and host discovery
• Enumerate exposed services
• Simulate brute-force authentication attempts
• Analyze system logs for attack traces
• Identify privilege escalation vectors
• Document findings in a professional penetration testing report

---

🧪 Lab Environment

🎯 Target Machine

• Ubuntu Server
• OpenSSH service enabled
• Standard user account with sudo privileges

💻 Attacker Machine

• Kali Linux
• Tools used: Nmap, SSH, Linux enumeration commands

🌐 Network

• Internal virtual LAN environment

🧠 Methodology

The assessment followed a structured penetration testing methodology:

1. Reconnaissance
2. Enumeration
3. Exploitation Simulation
4. Log Analysis
5. Privilege Escalation Assessment
6. Risk Evaluation
7. Reporting

---

🔍 Key Findings

• SSH service exposed to the network
• Multiple failed authentication attempts observed
• User account configured with full sudo privileges
• Presence of SUID binaries that may enable privilege escalation

⚠️ Overall Risk Level: High
