# Internal Network Penetration Test
## Overview
Conducted a full internal network penetration test as part of a simulated security engagement. The objective was to identify vulnerabilities, exploit weaknesses, and provide remediation strategies to improve the organization's security posture.
## Scope
- Internal network penetration testing
- Multiple target systems within a controlled lab environment
- Excluded: Denial of Service (DoS), Social Engineering
## Methodology
Followed a structured penetration testing methodology:
1. **Reconnaissance & Scanning**
- Identified open ports and services using Nmap
2. **Enumeration**
- Discovered vulnerable services and system configurations
3. **Exploitation**
- Leveraged known vulnerabilities using Metasploit
- Gained initial access to multiple systems
4. **Privilege Escalation**
- Escalated access to SYSTEM/Administrator level
- Used local exploit techniques
5. **Post-Exploitation**
- Navigated file systems and accessed sensitive data
- Identified lateral movement opportunities
6. **Reporting**
- Documented vulnerabilities, impact, and remediation steps
## Tools Used
- Kali Linux
- Metasploit Framework
- Nmap
## Key Findings
- Exploited SMB vulnerabilities (EternalBlue, ms08-067) to gain remote access
- Identified multiple Remote Code Execution (RCE) vulnerabilities
- Successfully performed privilege escalation on several systems
- Discovered outdated and unpatched systems across the network
- Weak access controls allowed unauthorized data access
## Vulnerability Summary
- Critical: 2
- High: 6
## Example Attacks
- SMB Exploitation (EternalBlue - MS17-010)
- NetAPI Exploit (MS08-067)
- IIS WebDAV Exploitation
- Rejetto HFS Remote Command Execution
- Multiple privilege escalation exploits (Windows Kernel & Services)
## Impact
- Full system compromise achieved on multiple machines
- Unauthorized access to sensitive files and administrator accounts
- Demonstrated risk of lateral movement within the network
## Recommendations
- Apply regular system patching and updates
- Disable outdated protocols (e.g., SMBv1)
- Implement network segmentation
- Strengthen firewall configurations
- Enforce least privilege access controls
- Monitor and log suspicious activity
## Skills Demonstrated
- Network Scanning & Enumeration
- Vulnerability Exploitation
- Privilege Escalation
- Post-Exploitation Techniques
- Security Assessment & Reporting
